A direct charge directly plugged into the kind of mobile phones, it was called Lvchong like we used to call "the AC adapter." Such chargers are equipped with cell phones, the quality of the original good, the highlight is that that is sufficient, and therefore the charge current design of the larger (Strictly speaking, the phone is under the control of the charge current), charging time is short. Some phones have a trickle after the full complement of electricity, some covered with cell phone immediately after the deadline, also wait in vain. Read the above concept you should know that it is normal and no longer silly to 14 hours.

£  £  charge straight for the effect of charge, depends on the phone because the cell phone charge control circuit, the cut-off voltage of a certain discrete, I measured the same batch of the same type of basic cell phone in between 4.09V to 4.21V . If the deadline is to say 4.09V, not covered, rather than the ideal capacity, continue to charge for a period of time would be more likely to eat more. But do not forget, even if there's trickle up the phone, just 4.09 and 4.21 of the charging voltage difference, mobile phones make up the trickle electric current is also a certain degree of dispersion, meeting if a large electric current, it becomes charge , 10 hours, there is also damage the laptop battery, I have encountered a number of mobile phone batteries in the rechargeable bad, electricity is also original, brand power there. If the battery charge is broken, causing leakage and so on, there may be damage to the cell phone, it is proposed that if we really want to make up electricity, should be controlled within 2 hours or less, should not be more than 8 hours.

£  £  My view is that lithium is effemination power, sufficient enough to eat. But a few hours less each time with more than six months, and each with more than a few hours but with less half a year to measure their own right.

£  £  original but also has been filling in question, we came across a group of mobile phones in the allocation of sufficient direct high failure rate. Fortunately, there is no breakdown voltage, if the voltage is high, a good-looking.

£  £  on the market have a large number of non-original AC adapters, not quality issues, poor quality you can imagine, because you are plugged into one end of the 220V AC, on the other side of the phone ... ... so in my own point of view , Does not recommend the use of non-original AC adapter. (At least the original trouble you have to back the pan)

£  £  2, Wall Décor & Hangings, there are two slots, can be put in front of the phone, put the back of the latitude battery, AC adapter and the need to use. Wall Décor & Hangings better quality of the original, many "intelligent", some of the brand has been able to achieve constant voltage constant current charging process and in charge after the end of a trickle up power. Although some of the brands do not have current process of constant pressure, but current and accurate control of parameters such as voltage, is good.

£  £  so-called smart, in fact, very simple, such as the battery MOTOROLA, there are a chip (read-only memory ROM), curing a number of coding, insert a battery charger, the charger to read out the code, know what kind of battery, the implementation of the The corresponding charge of the process, all pre-arranged. (Different models and different capacities, different parts of the supply, distribution and even different brands of batteries, different coding),

£  £  make a simple analogy, I shout 1, the first by you on the implementation of the program, I shout 2, the second by you on the implementation of the program, I do not cry, I cry, or 3 in advance, but did not agree with you, On the implementation of the refusal, the charger is the phenomenon of flashing red lights, can not charge (on display in the cell phone U4873 or non-approval). We do not think that there are single-chip CPU control.

£  £  "smart" is also reflected in the other, the battery is the NTC (thermistor) and resistance standards, different criteria for different batteries and chargers resistance constitutes loop, to determine the size of the charge current, and in charge current After the decision, according to the ambient temperature by thermistor charger and constitute another loop to adjust the size of the charge current. (Only some batteries resistance, some marked only the battery resistance, and some have two batteries.)

£  £  For example, certain types of batteries, thin and thick electrical power capacity, the best charge current should be different standards for these two batteries of resistance is different, so the Chargers "know" how much to thin electric The current charge for electricity to much of the thick charge current. In fact, the initiative is still one battery, charger and the battery is only constitute no more than a loop.

£  £  By the same token, when the temperature changes in the charge, the thermistor resistance to change, and constitute a charger circuit to adjust the size of the charge current,G5260 protection, to avoid overheating.

£  £  Now you know why Wall Décor & Hangings battery and battery slots have a piece of metal contact you.
£  £  Of course, at the same time you also know that a battery should be qualified to do what is right? Sometimes not entirely chargers, batteries do not, the charger can also play a role. At present, many domestic battery NTC will be used to replace the ordinary resistors to reduce costs and lost the role of the current adjustment, and the design selection, and so unreasonable that this is the way, the first aside. (Also makes sense, of them are listed on the clear)

£  £  Wall Décor & Hangings of the original electric current trickle up the general control of the relatively accurate, but the green light in the charger to power up after 2 hours, that is enough. This principle is, for lithium power to achieve the batteries should be enough capacity, filling more than useless. Li-pressed to pay electricity will be life and, occasionally, for 14 hours on several occasions may not damage the PCGA-BP2NX, but this would look very bad habits.

£  £  finished the original Wall Décor & Hangings, said the market brand of the Wall Décor & Hangings.

£  £  can say for sure that the brands on the market Wall Décor & Hangings charge of the process is not a strict compliance with: constant current, constant voltage charging process (so please tell me, I buy). They probably can be divided into several categories:

£  £  A, constant pressure, do not trickle up power: 4.2V to charge the battery that is closed to deal with such Wall Décor & Hangings, 14 hours, and so you are deceiving themselves. Although the result to 4.2V, but the cut-off, there is no trickle of course, there is no full charge.

£  £  In order to charge full, and some of the damage to the design, the cut-off voltage of 4.25V to change over, but was simply designed to protect the battery, such as cut-off board. So the battery is full, you will definitely meet the seat cloth, but your battery life has decreased. This is a charger with charge-off, not have to wait 14 hours is also good to use.

£  £  B, constant pressure, with fixed trickle up power: count conscientious design, have improved over the top, cut-off charge to 4.2V, a fixed resistance "leak" more current, as a result of this trickle is Fixed, plug the PCGA-BP2NY alone will never stop. As far as I normally measured in about 30 to 50mA. This charger, just did not turn green when the full charge, up to power about 2 hours more ideal, but the trickle of large, continue to charge the battery for 14 hours and no benefits.

£  £  C, constant pressure, the so-called smart-pulse: 4.2V to charge the battery cut-off, and then pulsed electric current trickle up. This is the so-called high-grade type, design a very good idea, but unfortunately fail to live up to the product, consistency is not good, that is to say you bought the good may be bad, perhaps. I measurement is flawed: too big pulse current 50 to 100mA, closely spaced pulses, which is equivalent to the charge. Expensive, so might as well use the B.

£  £  worthy of attention is that some Wall Décor & Hangings in pursuit of the AC adapter directly effect the rapid charge, the charge current design on the high side, close to 1C, this Wall Décor & Hangings, although not in breach of industry standards, but it can not be all "Wall Décor & Hangings Small current is slow temporarily as a "a familiar concept. But I do not recommend the use of such Wall Décor & Hangings.
£  £  only summarized above, and the pursuit of the "charging effect" and "a trickle charge plus fill power," and "charge-off increase in pulse," and "rapid increase in charge-off increase in power up." What they need is for users to stay a very good impression, and so on the user's cell to die, do not blame the basic charger, a most criticized: the PCGA-BP2R broke, with only half a year!

£  £  Wall Décor & Hangings election, it is best to have a digital multimeter, insert-air battery charge, the string into the amount of charge current multimeter, in the range of 250 to 350mA more appropriate, such as the green light to the charger, immediately won the amount of battery voltage, Between 4.15 to 4.20 compared to normal after the green light to observe the current string into the multimeter, in the range of 30 to 50mA more appropriate. If elected this Wall Décor & Hangings made, including the use of you there is no problem, why spend money to buy original wrong of it? I mean, of course, made in line with the standards, qualified products.

1. Battery factory, manufacturers have been activated to deal with, and the pre-charging, the batteries have more than electricity, a friend of mine said that the laptop battery in accordance with the adjustment period recharged, the standby is still a serious shortage of batteries assumption indeed genuine battery, this Circumstances should be extended for a further period of adjustment 3-5 at full charge and discharge.
     2. If you buy a new cell phone battery is a lithium-ion, 3 to 5 times before the charge commonly referred to as an adjustment period, more than 14 hours should be sufficient to ensure the full activation of the lithium-ion activity. Lithium-ion battery memory effect did not, but there is a strong inert, should be fully activated in order to guarantee the future be able to use to achieve the best performance.

     3. Some type automated intelligent rapid charger when the lights change direction, said only 90 percent full. Charger will automatically slow to change with full battery charge will be. After the battery will be full of the best, otherwise they will be used to shorten the time.

     4. Charger, lithium batteries do not need special discharge, discharge improper compaq battery will be damaged. When charging as much as possible in order to slow Chong Chongdian to reduce the fast charge mode; time not more than 24 hours. After three to five times the battery fully charge and discharge cycles of its internal chemicals will be all the "activation" to achieve the best results.

     5. There are a lot of users are often in charge when the phone open, in fact, it will hurt the mobile phone is easy life, because in charge of the process, the cell phone circuit boards will be hot at this time if there are external phone, you may Have a current back to the moment, the phone's internal parts damage.

     6.'s Battery life determined by the number of repeated charge-discharge, so to avoid battery power than when the charge, which will shorten the Armada E500 battery life. Phone off for more than 7 days, the first mobile phone batteries should be fully discharged, adequate electricity and then use.

     7. Handset battery self-discharge exist, not when Ni-MH battery will be a day of surplus capacity by about 1% of the discharge, lithium batteries a day by 0.2% to 0.3% discharge. In the battery to charge, try to use a dedicated outlet, and the Chargers do not share household electrical appliances such as TV outlet.

     8. Although the mobile phone network coverage in the region, but in the mobile phone charger off when the phone is no longer acceptable and the call. At this point, you can use the phone did not pass the transfer of functions will be transferred to the mobile phone side of the fixed-line, to prevent the loss of calls, this method is not for the mobile phone network coverage area or a weak signal and being unable to get through when applicable.

     9. Batteries will not be exposed to severe cold or heat, like a dog day weather, should not be on the phone in the car, stood in the scorching sun exposure; or get air-conditioned rooms, air-conditioning on the direct blow. When charging, the Armada M700 battery a little heat is normal, but it can not be Jinshou high temperature "suffering." In order to avoid this from happening, it is best at room temperature for charging, and not to cover anything on the phone.

     10. If the cell phone not to place too long, to the best cell phone battery to the maintenance department to apply for a living to deal with, you can own a constant voltage direct current, voltage adjustment for the 5 ~ 6V, current 500 ~ 600mA reverse The battery connected. Note that the liberalization of touch, up to be repeated three times, after such treatment, re-use original charger "adjustment" charge.

     11. Recharged when the longer the time is not good, not for the protection of the circuit full Armada V300 battery charge should be stopped immediately, otherwise the battery overheating due to heat or impact on performance.

     12. Lithium-ion battery charger must be selected precincts, or may fail to saturation, the impact on its performance. After the charge, should be avoided to place the charger in more than 12 hours or more, so that should not have long-term cell phone batteries and separation.

From the notebook of the birth of the day, the battery on the controversy has never stopped, because of persistent use of laptops is a very important indicator of technology, and the capacity of the laptop battery determines that laptop's important indicator. In the end how can we maximize the use of the battery to play the effect of extending the battery life of it? Now, we all set out for a few people often vulnerable to the misunderstanding: (without all that for now the most commonly used lithium-ion battery)

I, for the first time the use of batteries, three times before the need to charge 12 hours?
This is totally unnecessary. Because the laptop has improved power management circuits and charging management system, when the battery reached saturation, the control circuit will automatically switch to the open state, so long as the line is full, does not mean that you will be able to charge more for a long time with longer The.

Second, in order to prevent the memory effect, should it run out of electric charge it?
Every time charge of battery discharge before it is not necessary, but also harmful. Practice has proved that as: the depth of the battery will discharge unnecessary to shorten battery life, when the proposal to use about 10% of the toshiba battery can be recharged when the. When the battery, of course, there are still more than 30% of electricity when it would be better not to charge, because the memory effect is real.

Third, insert AC, the battery should be to win in order to prevent repeated charge and discharge it?
I suggest that is: do not have to! Of course, you can get lithium-ion battery discharge natural to refute me, saying that in the natural discharge the battery, if there is access to power will be repeated charge-discharge, reduced battery life. I give you a "no" answer to the following reasons:
1. Notebooks now have the power control circuit design of the features: When the battery is 90% (as most of the HP models) or 95% of the charge will be through natural discharge capacity of this time is 2 to the Mie Month, when the batteries do not have to idle for about a month to complete in order to maintain the battery charge and discharge capacity at this time you should be concerned about the battery should be about training the body and not be left idle after the re-charging.
2. Even if the battery "unfortunate" was once again charge, the loss will not be brought about by the long period of time than the PA3383U-1BRS consumption caused by the large decline in the number.
3. Your data than you or your notebook batteries are much more valuable, not only power all of a sudden you have a notebook injury, is unable to restore the data it is too late to regret the.

Fourth, long-term need to preserve battery power is full of it?
Read the following table on this clear: (percentage of saturation at the time of the initial value of the relative percentage)
Storage temperature of 40% of the state-of-charge 100% state of charge
0 degrees 98% (after one year) 94% (after one year)
25 degrees 96% (after one year) 80% (after one year)
40 degrees 85% (after one year) 65% (after one year)
60 degrees 75% (after one year) 60% (3 months)
It is clear that if the long-term preservation of the battery, as far as possible on the dry and low temperature environment so that the remaining battery power in about 40% of the best. Of course, the best month we should come out with a battery, the battery can ensure a good state of preservation, and not let the loss of full electricity and cell damage.

Fifth, as far as possible in how to use the notebook to extend the use of time?
1. To reduce the brightness of the screen. However, large-screen LCD power consumption, reduce the brightness can be used to extend the time.
2. PowerPlay and open SpeedStep power-saving features, and so on. Now the notebook and display processor chips have a lower frequency and voltage to extend the use of the function of the time, open the corresponding options can significantly extend the PA3107U-1BRS life.
3. The use of hard disk drive and the deceleration of the software: NERO DriveSpeed, PowerBooster software can reduce the drive, hard disk drives, such as speed, can effectively reduce the notebook.
To thank the moderator
I used to use on the existence of two different
After the attention of the next
I bought books on the battery had not been to the two did not have any problems out
My battery is always on the machine, has never won, because the books had to be supported by a few feet
~ ~ Come Learning to learn and I do not have the PA3285U-1BRS-ah, has been used to power batteries and then charging and discharging a month
I would like to thank the landlord to 1, 10, previously really did not know that the way, thanks to share!
Battery maintenance is a controversial issue!
Battery has been since last drop Oh
Fear is a sudden power ah
The importance of hard science knowledge, I would like to thank
It seems my book is to die! An electric charge only 2 hours!

In fact, the battery does not take into account the use of too much attention, in other words is also taken into account is not much use. A number of batteries can be used, the more the difference from its own battery manufacturing of individual differences, rather than using the method. In addition to the quality of their batteries, the laptop battery life of its own is limited. Once a battery production line, which began life goes by. No matter whether you use lithium batteries in the life of only two to three years. Battery capacity decrease of one of the important reasons or due to oxidation caused by the increase in internal resistance, cell resistance to reach the final of a point, although this time the battery is fully charged, the battery can not release the stored electricity. Many of you will be the first time that the use of lithium batteries should be charging more than 16 hours, so as to fully activate the battery, in fact, did not do so, then this is the popular Ni-Cd or Ni-MH battery charging method for lithium-ion batteries for Does not apply. This is because at the core of the lithium polymer batteries in theory, no memory effect and, even if there is entirely negligible. Therefore, only hub 3 hours or so on can, show that if the charge has been completed and has no need to use an external power supply, you can power off, do not have to wait such a long time.

In fact, battery maintenance has been a notebook computer users a hot topic, and
In the Forum's major notebook battery plate, has long been the subject of consensus. PSP users now have begun to concern the subject, but in fact there's a lot of errors, in the final analysis, comes from two aspects, one is "thinking does not keep pace with the nickel-metal hydride batteries to lithium battery change," another more funny is From the cell phone, because in fact the majority of mobile phone users access to the first use of repeatedly charging the toshiba battery device, it will be granted to the phone number used to extend to the PSP. I do not have the capacity to the majority of PSP users trained experts, and there is no need for that. There is no absolute truth and what, I do not like some of the rationalism of the supremacy of friends, their promises to the effect that a certain theory is correct, and all have to convince him, I will only forum in the major notebook and electrical industry Senior engineers generally agree that the point of view to share with you. In the final analysis, PSP is expendable, no matter how hard you again, the battery life span of only two or three years. If you feel that the PSP batteries in order to bring little to almost no effect of the so-called maintenance, willingly put together to fully charge and discharge time and frequent disruptions in the game, waiting for the charge, then you do not have to continue to read down.

I put some of the most vulnerable to clarify the misunderstanding, and I think that given the right perspective and practices.

A misunderstanding: PSP need to buy it back again three times in order to activate the charge and discharge the battery. Unless you buy the PSP is more than one year of product inventory, or not to do so, because the batteries in the Satellite A75 when the factory has been activated, and the batteries in the package into a PSP battery time and after a considerable In the activation of the test, so you get the battery in hand, has long been activated before, three times longer charge-discharge process is unnecessary to increase the battery wear and tear.

Second misunderstanding: the first charge must be sufficient enough for 12 hours. For those who do not have this early battery control circuit of the Ni-MH battery device is applied, but now has a smart charge-discharge control module for the PSP is a joke, when the PSP battery is full, the charge current will be automatically cut off, and Shows that the system as "an external power supply." Even if you continue to charge 120 hours, there will not be any change in the state, generally speaking, completely full of 3 hours, and the rest of the "charge" is just a waste of their time. It is time to get the new machines should first get a rechargeable power shine.

Three errors: the battery once a month need to fully take charge. The memory effect of a strong Ni-MH battery, which is an essential task, but lithium batteries, the cycle is too frequent, and lithium batteries in theory, is to remove the memory effect, even if there had been significantly weakened negligible The extent, if you use the Satellite A70 battery very frequently, you should discharge the battery to the relatively low (about 10 ~ 15%) rechargeable, but that even if the discharge machines are not open (0 to 1%), of belonging to the Li-ion battery The greater the depth of the injury discharge, in general every 2 months to do so once the operation of it. If you use very little battery, so long as every three months the first time this operation can be had.

Four errors: Edge edges charge, or after the completion of the charge will continue to use an external power supply and will damage the host cell. This is one of the most ridiculous argument. The so-called E-hole, and sufficient time, and other aspects of the mechanism of theoretical argument, in practice, how much can respond to it? Industrial batteries are the views of academics first and foremost not unified. There are still differences between theory, be used to guide consumers on how to use the actual? The PA3384U-1BRS battery is divided into normal wear and tear and wear and tear and wear and tear of injuries, and the use of an external power supply while charging while the use of real wear and tear caused by the extent of the battery fully within the scope of normal wear and tear, that is, no matter how the theory of the maintenance of the system, all batteries Will be aging, which like magic how the cosmetics and beauty maintenance can not stop the old woman into a maximum of only delay it, but the window dressing played by the real effect of what can be the number, which is by no means the theory can not be explained - Respect for the actual experience is the correct and scientific understanding of the concept. Some may say that the only way to avoid aging battery is not in use (so many people would choose to take the battery), but to make a PSP portable lose its meaning, and secondly, even if the battery in the state archive, but also over time And the extension of the natural aging. The battery is actually a consumables, as long as the battery you bring enough fun and easy, I would like to be at the expense of their value.

1, for a new laptop battery charge

In the use of lithium batteries should be noted that for a period of time after the battery is placed into hibernation, lower than normal capacity at this time, the time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycle of the battery can be activated, the resumption of normal capacity. As the battery lithium own characteristics, its decision is almost no memory effect. Therefore, cell phone users in a new lithium battery in the activation process does not require special methods and equipment. Not only is the theory that, from my own practice, from the very beginning, the use of standard methods of charging that "activation" is the best way. Lithium batteries for the "activation", a large number of claims: the time to charge more than 12 hours, repeated three times to do in order to activate the battery. "The first three necessary and sufficient to charge more than 12 hours", it is obvious from the nickel battery (such as nickel-cadmium and nickel metal hydride) inherited. This is why it can be said is the beginning of miscommunication. Lithium batteries and nickel battery charge and discharge characteristics of a very big difference, but also very clear to tell you that I have had access to all the serious official stressed that all technical information and charge-off will discharge lithium batteries, especially lithium liquid Ion toshiba battery causing great harm. According to the charge and therefore the best time and method of charging standards, in particular for not more than 12 hours of super-long charge. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of charging. This
, The lithium battery in the phone or battery charger will automatically stop after a charge, there is no electricity nickel charger for 10 hours the so-called "trickle" charge. In other words, if your lithium batteries in full, on the white charger is also sufficient. And we can not guarantee that no one battery charge and discharge protection circuit features and never change the quality of safety, so your batteries will be in the long-term hovering on the brink of danger. This is also another charge against the chief reason. In addition to certain mobile phones, the charge for more than a certain amount of time, if not remove the charger, this time not only to stop charging system, will be the beginning of discharge - charge cycle. This is perhaps the manufacturer has its own purpose, it is clear that on the phone and battery / charger is the life span of a negative. At the same time, long charging would take a long time, often at night, and to our country's power grid situation, at night in many parts of the relatively high voltage, but also volatile. Said earlier, the lithium Satellite A70 battery is very delicate than nickel in the electric charge and discharge aspects of fluctuations in the capacity of resistance is much less, so this brings additional risk. In addition, can not be ignored other aspects of a lithium battery that is not the same for over-discharge, over-discharge of lithium batteries is also very unfavorable. This leads to the following question.

2, in normal use when the charge should be

In our forums, often see this as the number of charging and discharging is limited, so should the cell phone battery power used up as much as possible and then charge. But I find on a lithium-ion battery charge and discharge cycle test table, on the life cycle of figures is as follows:

Life cycle (10% DOD):> 1000 times

Life cycle (100% DOD):> 200 times

DOD is the depth of the discharge of which the initials. Can be seen from the table, the number of rechargeable and about the depth of discharge, 10% DOD at the time of the life cycle than 100% DOD's a lot longer. Of course, if the actual charge equivalent to the total capacity of the relative: 10% * 1000% * 100,100 = 200 = 200, which is the complete charge and discharge, or better than some, but in front of friends do say that some of the amendments: normal Under the circumstances, you should have a reservation in accordance with the remaining PA3384U-1BRS battery power and then run out of filling the principle of charging, but if your battery is expected in the first 2 days you can not adhere to the whole day, should start on time charge, of course, if you are willing to back A charger to the office and when Bielun. And you need to charge in order to cope with the anticipated upcoming busy communications will lead to an important event, even if there are a lot of battery power over time, then you just charge ahead of time because you do not have a real loss "1" sub-charge cycle life , That is, "0.x" times, but often this will be a very small x. The remaining battery power and then run out of charge to the principle does not mean that you go to the extreme. And charging the same length of a widespread view that "as far as possible the cell phone batteries run out of power, it is best to use automatic shutdown." This is only a matter of fact on nickel batteries, to avoid occurrence of memory effect, unfortunately, it is also spread of lithium batteries on this. It has been too low because the cell phone battery warning appears, do not continue to use the charge has been used in automatic shutdown of the case. The outcome of this case, the phone was in charge of the boot in and there was no response, had to give customer service overhaul. In fact, this is due to the battery discharge caused as a result of over-voltage is too low, that does not have the normal charge of the boot and conditions.

3, Li-ion VGP-BPS5 for mobile phones in the right way

To sum up, I lithium batteries used in mobile phone charging and discharging of the most important tips are:

(1) In accordance with standard procedures and charging time, even before the three to do so;

(2) When the phone prompts when electricity is too low and should start charging as much as possible in a timely manner;

A straight charge, directly from the phone on the kind, some people like to call Lvchong, we used to call "AC adapters." Such as mobile phone chargers are allocated, the original quality are good, prominent is the charge that is used, so the charge current designs are larger (Strictly speaking the phone is controlled by the charge current), charging time is short. Some phones have a trickle after the meeting, and some mobile phones after the deadline for full, laptop battery and so it is futile. Read the above concepts you should know that it is normal, but do not have to Shahu Hu to 14 hours.

£  £  charge straight for the charging effect depends on the phone, because the charge control circuit on the phone, the deadline for the discrete voltage to a certain extent, I measured the same batch the same basic models of mobile phones in 4.09 V to 4.21 V between . 4.09 V, that is to say if the deadline, even full, not the ideal capacity, continue to charge for a period of time may be more eat more. But do not forget, even with the trickle-power mobile phones, 4.09 and 4.21 as the charging voltage difference, phone the trickle-electric current to a certain extent the discrete, if completed, the current large, it becomes charge , 10 hours, there is damage to the battery, I have encountered many phone battery charge in a bad situation, there are original, brand, also. If the bad battery charge, resulting in leakage, etc., may also damage the phone, so if you really want to fill the proposed electricity, should be controlled in less than two hours, not to over eight hours.

£  £  My view is that lithium is Jiaoqi, sufficient enough to eat. But a few hours less each with more than half a year, and each with more than a few hours but less half a year, his measure it.

£  £  original straight but also have a problem filling the time, we encountered a number in the phone, with a straight charge of the high failure rate. Fortunately, no-voltage fault is powerbook battery, if a high-voltage, a good-looking.

£  £  the market a large number of non-original AC adapters, no problem for good quality, poor-quality you can imagine, because you are planted on the side of the 220 V AC, the other on the phone…… So in my personal view , Does not recommend using non-original AC adapters. (At least the original just to have you back to the pot)

£  £  2, Zuochong, there are two slots, can be put in front of the phone, behind-the battery, and AC adapters with the need to use. Zuochong better quality of the original, many with "smart", some brands of constant current constant pressure can basically do the charging process, and in charge after the end of a trickle-power process. Although some brands of constant current constant pressure failed to do the process, but the current and voltage control parameters such as accuracy, is also good.

£  £  so-called intelligent, in fact very simple, such as the battery MOTOROLA, the internal a-chip (read-only memory ROM), curing a number of coding, insert the battery chargers, chargers read out the code, know what kind of PowerBook G4 battery, the Executive The corresponding charging process, everything is arranged in advance. (Different models and different capacity, the supply of different areas, even with different brands of batteries, have different coding),

£  £  make a simple analogy, I call one, you first on the implementation of the programme, I shout 2, the second by you on the implementation of the programme, what I do not shout, I shout or 3 but did not advance and you agree, and On the refusal to implement, the phenomenon is the charger flashing red light, can not be charged (on the phone to display non-authorized batteries). Not everyone imagined, MCU CPU control.

£  £  "smart" also reflected in some other areas, that is, battery NTC (thermistor) and resistance standards, different cells by different standards resistance and a charger circuit, to determine the size of the charge current, and in charge current After the decision, depending on the ambient temperature, thermal resistance and a charger another circuit to adjust the size of the charge current. (Only some batteries thermal resistance, some batteries only standard way, and some have two batteries.)

£  £  such as a certain type of battery, thick, thin, and the capacity of different, the best charge current should also be different, so it two batteries of standard resistance is different, this charger on the "know" how much to thin, The charge current, as thick, how much to charge current. In fact, the initiative is still one battery, iBook G3 battery charger and only constitutes a just a loop.

£  £  the same token, when the charging temperature changes, the thermistor's resistance changes, and a charger circuit to adjust the charge current size, battery protection, to avoid overheating.

£  £  Now you know why Zuochong batteries and battery slots have a row of metal contact with the film it.
£  £  course, you are also aware that a qualified battery should do what it has » Sometimes can not depend on the charger, batteries do not, the charger can also play a role. At present, many domestic battery NTC will be used to replace the general resistance to reduce costs, loss of the role of the current adjustment, the design selection unreasonable, and so on, this is the way, not to press. (Also reasonable, Read to clear)

£  £  original Zuochong the current trickle-general, the control of relatively accurate, but the green light to the charger, two hours after the meeting that is enough. Or this principle, lithium, to reach the batteries should be sufficient capacity, filling more than useless. Press lithium to pay life, and occasionally several times to 14 hours may not damage the iBook G4 battery, but the bad habits so on.

£  £  Zuochong finished the original, the brand on the market that the Zuochong.

£  £  sure that the brands on the market Zuochong the charging process is not a strict compliance with: constant, constant pressure of the charging process (so, please tell me, I buy). They probably can be divided into several categories:

£  £  A, constant pressure, not trickle-power: The battery charge is close to 4.2 V, encountered such Zuochong, such as 14 hours you are cheating themselves. Although due to a 4.2 V, but the deadline has been, without a trickle of course, not sufficient enough.

£  £  enough to charge, on the design of some of the damage to the voltage to close to 4.25 V above, it was simply designed to protect the battery, and other board deadline. So the battery charge is enough, you will also have Zuochong satisfied, but your battery life has decreased. With this charger is a charge, do not have to use 14 hours is also very good.

£  £  B, constant pressure, with fixed trickle-power: the design operator with a conscience, than the above improvements, the deadline for filling to 4.2 V, with a fixed resistance "leakage" from some current, this is due to trickle Fixed, plug in the A2 battery alone and will never stop. I generally measured in 30 to 50 mA around. Use this charger, not just when the green light to charge enough to fill about two hours, ideal, but a trickle too large to continue to charge 14 hours of battery benefits.

£  £  C, constant pressure, the so-called smart-Pulse: The battery charge close to 4.2 V, then pulsed current trickle-power. This is the so-called high-grade type, design ideas is very good, but it is a pity that product is not Clear the Air, consistency, well, that is to say, you may be better perhaps Mai Daoshou the bad. I measure is flawed: too much pulse current 50-100 mA, the pulse of, or a charge. Also expensive, so better to use B.

£  £  It is worth noting that some Zuochong pursuit of AC adapters for the rapid effects of direct charge, the charge current design of the high side, close to 1 C, such Zuochong, although not in violation of industry standards, but not all "Zuochong Filling small current is slow, "a concept to understand. But I do not recommend the use of such Zuochong.
£  £  only summarized above, in order to seek "charging effect" and "a trickle-charge increases," and "increase the charge pulse," "too fast, filling and fill". What they need is for users to stay a very good impression, and other users of A3H battery can not, do not blame the basic charger, at most, scolded one: breaking batteries, with only half a year!

£  £  Zuochong election, the best way is to have a digital multimeter, insert the air battery charge, the string of charge current multimeter, 250-350 mA of more appropriate, such as the green light to the charger, immediately scored voltage of the battery, 4.15 to 4.20 between the relatively normal, after the green light to observe the current string of multimeter, in 30 to 50 mA range more appropriate. If elected the domestic Zuochong, the package you use no problem, why spend money to buy original innocence? » I, of course, is that domestic standards in line with the qualified products.

£  £  It is worth noting: brand Zuochong basically not smart, Nayi Pai-metal contact, in addition to being negative, the rest are let you look at the (individual has a thermal resistance of the contact-useful). But the original understanding of the method Zuochong smart, too smart do not have to pursue the mystery too. (Now know that some of the above battery why should simplify the material it »)

£  £  products have certain parameters of discrete, some brand Zuochong deadline voltage³¬Ήύ4.2 V, but as long as no more than 4.25 V, is to allow a certain error, the batteries have an impact, the effect is not.

Basically, the current mobile phone batteries are allocated by the lithium-ion battery, so I Below is against what the lithium-ion rechargeable laptop battery knowledge. Nickel-metal hydride batteries are different, not talk about here.

£  £  1, lithium-ion battery nominal voltage 3.7 V (3.6V), charging cut-off voltage 4.2 V (4.1V, batteries under the brands have different design). (Li-ion batteries standard argument is: lithium-ion battery)

£  £  2, the demand for lithium-ion batteries (GB/T18287 2000 norms): First of all constant current charging that certain current and the battery voltage with the charging process to gradually increase, when the battery voltage to 4.2 V (4.1V), Charging for the constant pressure to constant current charge, that is, a certain voltage, current batteries under the saturation level, with the charging process to gradually reduce, when reduced to 0.01 C, that end-of-charge. (C nominal capacity of the battery is a control that current methods, such as the asus battery is 1000 mAh capacity, 1 C is the charge current 1000 mA, attention is not mA mAh, 0.01C is 10 mA.) Course, a standardized form that is 0.01 C5A, here I simplified.

£  £  3, why that charge for the end of 0.01 C: GB/T18287-2000 This is the national standard set, but also the discussions. Before it was generally to 20 mA to end, the Ministry of Posts and Telecommunications industry standards YD/T998-1999 is such requirements, that is, no matter how much battery capacity, and stop all current 20 mA. GB provisions of 0.01 C to charge more full, the manufacturers through the identification of beneficial side. In addition, the provisions of the GB charging time is not more than eight hours, that is to say, even if has not yet reached 0.01 C, 8 hours to, and also the end of that charge. (No problem for the quality of the iBook G4 battery, should be in eight hours to reach 0.01 C, the poor quality batteries, and so it is meaningless)

£  £  4, how to distinguish between the battery is 4.1 V or 4.2 V: consumers are unable to differentiate between, depending on batteries manufacturers of products specifications. Some brands of batteries is 4.1 V and 4.2 V common, such as A & TB (Toshiba), basic domestic manufacturers is 4.2 V, but there are also exceptions, such as Tianjin Lishen is 4.1 V (but also by a 4.2 V).

£  £  5, the 4.1 V rechargeable batteries of 4.2 V to happen: the battery capacity will increase, I feel very good use of standby time, but will cut short battery life. For example, the original 500, reduced to 300. Similarly, the 4.2 V-off charge of the batteries, will cut short-lived. Lithium-ion batteries is a very delicate.

£  £  6, since the batteries are protected within the board, whether we can be at ease: No, because the deadline for the protection of the plate parameters is 4.35 V (this is still good, the bad to 4.4΅½4.5 V), the event was to protect the plate , If every time a charge, the A2 battery will soon decay.

£  £  7, much of the charge current is appropriate: the smaller the theory of the good battery. But you can not charge the battery in a bar, such as three days. GB provides low-rate charge is 0.2 C (arbitration charging standard), also above the 1000 mAh capacity of the battery as an example, is 200 mA, then we estimated this battery can be more than five hours filling enough. (Current capacity mAh = mA × time h)
£  £  national technical supervision departments identified lithium capacity is 1 C of the high-rate charge to 0.2 C low-rate discharge, time to calculate the value of capacity, five times the number of tests, one of the capacity of the end of trial. (5 is a chance that if the first test on a pass, not the back four times) testing before allowing a pre-cycle, 1 C is a constant current charge to 4.2 V stop, but not behind the constant pressure to 0.01 C of the process, not 14 hours.

£  £  8, lithium-ion batteries can withstand much of the charge current: manufacturers test can be high, but the ratio requirements for the elevation of 1 C, also above the battery as an example, over one hour to full. Such a charge current, A3H battery can bear? » For the current lithium-ion batteries, it is Xiao Yisi. There is no national standard on the Charger, is enforced by the Ministry of Posts and Telecommunications industry standards YD/T998 1999 / 2, inside the current provisions of the charger should be no larger than 1 C.

£  £  9, the provisions of what life is: To put it simply refers to a battery charge 1 C, N, 1 C discharge, the capacity dropped to 70 percent, when the N is the life. Is not to say that 300 can also use, the 301 can not be used. GB provisions of life shall not be less than 300. We normally not detected the use of the conditions when such a harsh and life will be longer.

First, the current epidemic is a practice that the use of electricity in the long working hours, many users of laptop battery will discharge that this can extend battery life. In fact, guarantee a good habits, under the premise Remove the battery module is the laptop battery life is not unduly affected. Remove the battery for the users did not need to pay attention to the frequent swapping is not the power, it is because of the short period of time may seem modest plug power supply, will also have a battery charge and discharge process, the frequent charge and discharge operation to be shortened Battery life while the battery on the side of the users, the best time to time (about a month or so), it will be Add to notebook computer batteries to charge, this battery can keep the best state If the battery is idle for too long, would lead to reduced capacity.

Second, the lithium-ion battery, it is not necessary to conduct further depletion of electricity charge, it is because lithium-ion batteries almost no memory effect. The so-called memory effect occurred in nickel chrome or nickel-hydrogen battery on the battery, which did not fully discharge the battery in the case, will have a crystallization of reaction, resulting in ibm battery capacity of the temporary reduction, if we eliminate this memory effect Can be done several full battery charge and discharge cycle, there may come back to save the battery.

Another issue is the need to pay attention to the use of the environment, although the mobile computing will encounter a variety of environment, but at room temperature for the use of battery life or to guarantee a certain benefit, cooling the overheated environment of temperature on notebook computers will Cause harm. In addition, when using the transformer operation, from the outside world power will support the system is running on the one hand, on the one hand, rechargeable ThinkPad R51 battery, the charging process than the shutdown of the state of charge operation slower, if you want to fast charge, or the best In a state shutdown.

Some users complained that some of its own battery power display credibility is not high, in fact, these products in a special calculation of the battery capacity of the chip. Generally speaking, the percentage of notebook computer batteries in the display or a certain credibility, it should be noted that from time to time, do the best for the battery calibration operation, to calculate the ThinkPad T41 battery capacity chip correction possible error. Calibration work carried out by two methods: unplug the external power supply, turn off power management in the power-saving mode, and discharge their own computer to shut down the use of random or in the BIOS software provided by the calibration.

This question is closely above the activation of the batteries, to mention a battery factory in the hands of users to have electrodes passive phenomenon, in order to activate the laptop battery charge deep deep discharge cycles three times, in fact, this issue into a deep charge is not is to Filling 12 hours of the issue.

The answer is sufficient and does not require 12 hours.

Early phone nickel-hydrogen batteries because of the need to complement and trickle charge process, to achieve the perfect filling enough, and may need about five hours, but also do not need the 12 hours. The lithium-ion rechargeable battery constant current constant pressure of a decision it is the deep-charging time without 12 hours.

The lithium-ion battery Some people may ask, since the constant pressure phase of the current lithium-ion batteries gradually decreased, when the current is not small to infinitesimal when the charge is the real deep. The author has drawn constant pressure to reduce the current stage of the time, it conducted a number of curve fitting and found that this curve can use 1 / x function of the way and close to zero current, actual test lithium-ion inspiron battery itself because the Self-discharge phenomenon, this is never zero-current reach.

To 600 mAh battery as an example, set up to the current 0.01 C (that is, 6 mA), the 1 C charging time is not more than 150 minutes, then set up to the current 0.001 C (that is, 0.6 mA), it may be the charging time of 10 hours -- -- Because this precision instrument issues, has been unable to obtain accurate, but from 0.01 C to 0.001 C, as calculated by the capacity of only 1.7 mAh, to the use of more than seven hours in exchange for it is only less than three thousandths of the Capacity is of no practical significance.

Moreover, there are other ways of charging, such as pulse charging the lithium-ion Inspiron 6000 battery to achieve the 4.2 V voltage limitations, it is not closing the smallest current judgement stage, after 150 minutes in general it is a full 100% charge. Many phone With the pulse charging.

It has been using a mobile phone display sufficient enough, then Zuochong to recharge the phone to confirm the sufficient degree of saturation, the less stringent testing methods.

Zuochong first real test showed that green light is not sufficient enough or not a basis.

Detection of lithium-ion battery charge enough or not the only way is the ultimate test is not in charge (or discharge) a state of the lithium-ion battery voltage. Reduce the current stage of the so-called constant pressure, its real purpose is to gradually reduce the resistance of the battery charge current and because of the additional voltage, when the current small to 0.01 C, for example 6 mA, with the Inspiron 700m battery by the current internal resistance (usually in the 200 Cents within the EU) was only 1 mV, it that when the voltage is no current state of the battery voltage.

Second, the phone does not necessarily mean that the reference voltage Zuochong the reference voltage, cell phone batteries that charge enough to Zuochong, Zuochong not think enough has been sufficient, but to continue charging.

Laptop battery maintenance method - on the proper use and maintenance of batteries? » In accordance with the correct method to use, the laptop battery can still longevity. Below talk about the use of methods:

  Laptop battery maintenance methods - 1, you want to activate the new battery longevity of notebook batteries, must have a good beginning, it was from the start with the purchase of notebook. New laptop in the first boot with a battery should be 3 percent of the electricity (this is also a common practice of manufacturers. If you buy the first to open the notebook, has a battery that is certainly used by others), and at this time, you Should not use an external power source, the compaq battery in the remainder of the exhaustion of power, until the shutdown, and then use an external power supply charge. After returning home, but also to the battery charge after the exhaustion of power, charging time must be over 12 hours, repeatedly done three times, in order to activate the battery, in order for future use and lay a sound foundation.

Laptop battery maintenance methods - 2, to minimize the number of batteries used this method seems to give people some feeling stingy, but it is also the most effective. We should know that the number of battery charging and discharging directly related to life, filling each one, Presario 700 battery on a step forward to retirement. We propose to make full use of an external power supply, use an external battery power should be removed. Some friends convenience, often several times a day in the power plug, and notebook computers equipped with batteries, to do so, the greater the damage to the battery. Because each access to an external power supply equivalent to a battery charger, a battery naturally Zheshou.

  Laptop battery maintenance methods - 3, after the exhaustion of electricity charge and avoid charging time is too long regardless of your notebook to use lithium or nickel-hydrogen power, electricity consumption to a certain exhaustion after filling (less than 1% of electricity), which is Avoid the memory effect the best way. On lithium not the memory effect, I have been in front of businesses that are irresponsible and misleading. Lithium will be the same memory effect, it is only the memory effect is somewhat smaller than the nickel-hydrogen only. And cell phone Presario 900 battery charging the same method as that, when you give laptop batteries, to avoid long time, the general control within 12 hours. As for the Prevention of exposure to prevent exposed to moisture, prevent erosion of chemical liquids, avoid contact with the metal battery of attention to matters such as contacts, will not mention here the

Laptop battery maintenance is the most user issues of concern, perhaps the prevalence of mobile phone batteries to let people have a certain understanding, Oh…… but obviously not enough in-depth understanding of these, so much misunderstanding.

     First of all need to be clear that the so-called 'lithium batteries no memory efficiency' argument is absolutely wrong, lithium batteries and memory efficiency is not so strong nickel-metal hydride batteries only, with the charge for the use of lithium batteries is to a certain extent of the injury! !

     The best course is to use once the battery will recharge its full shine, shine is the so-called completely shut down power management of energy-saving options used machine hardware or automatic shutdown of the alarm. The lithium batteries in laptop computers are charging and discharging control / protection circuitry, as long as these circuits are functioning properly, laptop battery recharging is not excessive, in order to reduce the batteries discharge from the frequent charge, now laptop batteries The charge and discharge control / protection circuit will be in control of inspiron battery power consumption dropped to a certain extent when it started charging, rather than a decline in electricity consumption on the charge immediately, thus effectively reducing the number of frequent recharging, various brands of notebook computers have different control , Such as IBM's is 95 percent of the models start charging, Compaq models are part of 92%, Toshiba models are part of 94%, but the same purpose.

     Of course, than the control circuit is the better way to the battery had not (because the normal lithium batteries per day will automatically discharge 1 to 2 percent, the daily charge will automatically 1-2), but there will be a body Comparing holes ugly…… but for some ultra-light machine, the battery is part of it to balance the weight, remove the battery after the opening screen machines will be back inverted…… I also follow the fallen……

     How to choose depends on your own, I personally do not want to because of a battery using a laptop computer and the impact of fun, so I will never win the battery, my method is to buy a piece of the same specifications of the old batteries, usually on the use of This one, the need to use the 1691P when the then state of good plug in the battery.

     Various manufacturers generally have their own power management procedures were available, to make their own notebook computers to maintain performance at the same time get the most battery life, these power management procedures generally provide a lot of custom power management settings, and some also Provide battery calibration, can show the real power and battery charging and discharging number, Compaq, Toshiba, IBM and SONY power management procedures are among the best. IBM's power management procedures can also automatically diagnose your battery status and use different colors, very advanced.

     Even under the most standard approach to the use of 75UYF life, battery or will the loss, it is because lithium batteries will be aging, just as our own even in the maintenance of good will, like the old……

     Another problem is that the battery after a certain aging, Windows shown in the percentage of battery power will not accurate, or even some new batteries will be this time, the battery to the 0% can use the half-hour or even one hour, or 30 percent of electricity is also available on the automatic shutdown of the examples of a common occurrence, it is because Windows power management and design of the battery can not be compatible with all due. Particularly the second-hand laptop battery more likely to have such a problem. This does not mean that the battery problems, it is best to use their own or Battery Mark PCMark2002 test to determine the actual time (to close all the power-saving options so as not to interfere with the Windows Zizuocongming).

     Different charging time of different notebook computers, Dell notebook computers can be part of within one hour fast charge 90%, IBM's charge on the relatively slow (even open the fast-charge function), but for all notebook computers 8N544, are turned off charge This is the fastest way. Because in the shutdown of the adapters are used for all the current charge.

     For long-term use of the AC users, the proposed monthly release a complete battery charge, so you can keep the battery in the best condition, but do not do a thorough frequent charge and discharge operation, which will shorten the life of your battery.

Ordinary people home to have a notebook computer is not difficult, although the value notebook or down a lot, but as a high-tech products it is still very delicate of gas, inadequate care if you are likely to affect the normal work! For each of its parts can not be taken lightly, some notebooks will likens the body's blood cells, although it is not very appropriate laptop battery, but so that its importance. Today, Xiaobian to collect more information, to Jiehuaxianfo, and friends to share the laptop battery maintenance problems.

 
First, activate the new battery

New laptop in the first start-up, the battery itself should be 3 percent of the electricity (this is also a common practice of manufacturers. If you buy the first to open the notebook, has a battery that is certainly being used by others). At this point, you should have exhausted the battery until the shutdown, and then use an external power rechargeable inspiron battery, charging time must be over 12 hours, repeatedly done three times, so as to completely activate the battery, can effectively improve the battery life.

Second, to reduce the number of battery life

To minimize the number of batteries used, this method gives impression that some²»Λ¬, since bought a battery is not so frequently used, it bought Zuoshen. Having said that, but the number of battery charging and discharging directly related to life, filling each one, battery on a step forward to aging. We propose to make full use of an external power supply, use an external 1691Ppower should be removed. Some friends convenience, often several times a day in the power plug, and notebook computers equipped with batteries, to do so, the greater the damage to the battery. Because each access to an external power supply equivalent to a battery charger, battery life naturally shortened by some.

Third, to avoid prolonged charge

After the exhaustion of electricity charge and avoid charging time is too long, regardless of your notebook to use lithium or nickel-hydrogen power, electricity consumption to a certain exhaustion after filling (less than 1% of electricity), which is to avoid the best way memory effect . On lithium not the memory effect, I have been in front of businesses that are irresponsible and misleading. Lithium will be the same memory effect, it is only the memory effect is somewhat smaller than the nickel-hydrogen only. And cell phone 75UYF charging the same method as that, when you give laptop batteries, to avoid long time, the general control within 12 hours. As for the Prevention of exposure to prevent exposed to moisture, prevent erosion of chemical liquids, avoid contact with the metal battery of attention to matters such as access, where it has not mentioned.

Fourth, do not have long-term maintenance of batteries

If long-term use of notebook batteries, the battery should be in a month to conduct a full charge and discharge, to maintain the vitality of the battery. Also if the long-term (over) not to use the laptop battery should be charged to about 50 percent, and once a year charge, to prevent excessive 8N544 discharge. If the charge when the shutdown likely to perform better, but does not require to be shut down.

Power supply monitoring system is operating with the power system automation arising from the operation, the system can substation in the exchange of power supply, control DC power supplies, backup power and switch state operating parameters, such as monitoring, alarm and other operational failures. So as to the timely discovery of the abnormal laptop battery situation of the power system ahead of time to prevent the power system to ensure continuous and reliable operation. At the same time, when the power system failure at the relay and circuit breakers and other equipment to provide secondary backup power operation, to protect the equipment.

Inspection is the backup battery power for the detection device, the main function of the single cell voltage, temperature, capacity and other parameters to detect, control and charging failure to provide alarm functions, thus it is reasonable to control the battery to extend compaq battery life And improve the reliability of the system.

Power monitoring system started in the late 1980s, when it can only monitor a separate DC power supply system or a Bureau (stations), and power monitoring level is low, and low reliability. After the 1990s, especially in recent years, along with the computer, communications technology and the rapid development of raising Inspiron 8000 battery the level of power equipment, power monitoring have gradually matured, that can monitor the development of multi-loop or even multiple systems.

Power operated power monitoring system with a reasonable controller, by controlling the high-voltage circuit breakers and other equipment of the relay, can fully realize the safe operation of power systems and automatic scheduling, dispatch electricity to meet the needs of modernization Armada E500 battery.

This power
Management of major equipment for the operation of small and medium-sized power substation and backup power monitoring and management, in order to better energy conservation backup Armada M700 battery, choose low-power MSP430F149 microcontroller as the processor.

When you have those big batteries can be used inside the lithium-ion rechargeable battery, you encountered a unique problem. Far more than 100 V bus voltage IC ruled out the standards for the transition charge and the use of excessive discharge of protection. In addition, since these batteries and battery series of self-discharge rate of small differences and eventually led to the charge imbalance. Therefore, you have to balance that the laptop battery. This design provides a great balance between protection and high voltage strategy. In Figure 1, the circuit monitor in a series of separate batteries, lithium-ion batteries. This circuit and a monitor connection and communication processors. This monitor monitor all the batteries in the battery, a problem in the time to open a protection switch and decided where and when the balance is necessary. This approach is easy to measure an arbitrary high-voltage bus.

PIC16LF88 a microcontroller directly from 3-4.2 V, access to the battery voltage energy. There's no need to regulators and the whole circuit of quiescent current of less than 1 μ A, thus minimizing the battery self-discharge. The event of non-reliability of some incidents, such as batteries from the battery, disconnect, the regulator diode D2 and fuse F1 in the protection of high-pressure monitor. Optocoupler connected to a compaq battery monitor and an asynchronous serial bus between a speed of 9600 baud. A monitor was driven by a broken line battery election election of a battery pack. Lotus-MOCD207M have a very stable large currents
Conversion ratio, so that it can be in the supply voltage range to do some set up the operation. Although the quiescent current oscillator close to 0, procedures available through the online serial pulse signal to send a wake-up monitor.

Monitor by measuring the M4050 unknown fixed voltage to measure the battery voltage. Reference points, operational amplifiers and voltage gain error led to the migration, this can be offset in the calibration software. As the temperature parameters of change, some residue there have been mistakes. R7 and R8 with a 25 ppm / ° C temperature coefficient Armada E500 battery. Volts of 0 to 50 ° C accuracy of the results is ± 7.5mV. Digital output offset by the baseline (point), volts or only when the necessary time to allow through the current. The same technique can be applied to the electric regulator.

The battery monitor flow through the action from the R2 the current 200 mA to balance the overloading of a battery. Although the splitter current ratio of the largest battery discharge current 12 A small, but he was still sufficient Armada M700 battery to meet the balance between different series of self-discharge the battery, a small difference.

Trainor said: "change the laptop battery cathode metal components, you can change the battery capacity of the curve, then mixing different metal depends on the content of the cathode can have the greatest power."

     Trainor said that the terms of the way the battery will not be too difficult, that is stored in the battery power (watt hours watt hours) and notebook computers, the average electricity consumption Xiangchu.

     High-performance lightweight notebook computer (usually weighs less than five pounds) may be supported by the number of hours to provide 58 watts of electricity , this notebook computer average electricity consumption is 12 watts or 12 watts and above, the best inspiron battery life is four hours. Now goal is to increase to 72 watts of electricity when the number of notebook computers and lower average electricity consumption to 9 watts.

     Trainor said: "We called this is 1-2-6, 1 for processors, chipsets for 2, 6 for the rest of the system. To have the life expectancy increased to eight hours, we propose that the mapping and chipsets Combo of our lab-built batteries have 72 watt hours of electricity, I believe to 2008, other companies have the capacity to produce this kind of Latitude CPX battery. "

     Notebook computers have improved by leaps and bounds to the use of the number of hours. Over the past few years, computer components manufacturers to continuously improve the efficiency of electricity. The average production of LCD panels as long as 3 watts of electricity, is a very significant step. LCD panels are usually on the consumption of the notebook computer 30% of the total power consumption.

     Also a big-screen hero is Intel's power-saving technology. With it, digital photos or graphics pixel opened wide, so allow more light to enter Latitude C600 battery. Under normal circumstances, allow more light partial white images, but chipsets will be closed within the light panel, photos or images appear to remain the same, but the overall power consumption from 480 watts down to 3.2 watts. (A part of the technology from Taiwan's unification-Optics Inc. Toppoly, access to Intel's venture capital fundsήΪΧ’).

     OLED (organic light-emitting display) technology may have to wait for a while can be used in notebook computers. Mobile phone manufacturers have been using this technology, but the screen and almost all of the dark, the only figure will be luminous, but the notebook computer screen is usually full of luminous, it may not be able to take advantage of savings on electricity consumption. The average power consumption of notebook computers 8 per cent of the total power consumption drives will also be improved Latitude C640 battery. Microsoft's WinHEC rally this spring, Samsung displayed a new hard drive, most of the information stored in the first flash memory, with flash help, can drive most of the time in a dormant state, thus the use of laptop computer battery time extended by half an hour or more than half an hour , Samsung said.

     Eden said that Intel's Yonah notebook computer chips in 2006 will come out in the first quarter, the chip power consumption than the Pentium M processor. In addition, the chip set will also use more efficient technologies. Chip components are usually much lower than the processor, so it will not use the same level of energy saving equipment.

     VIA (Via Technologies) company has recently developed a power-saving notebook computer chip C7.

     Despite many improvements Latitude C840 battery, consumers are not likely to see the notebook computer design significant change. Members of the fuel cell (fuel cells) the heat seemed Xiaotun, because fuel cell size, if they will reduce the need to spend more time and money. In addition, power also need improvement. Furthermore, rechargeable fuel cells have to spend money, but as long as lithium-ion batteries can be immediately plugged in charge, appears not to spend anything.

     Trainor said: "fuel cells into the computer may have to 10 years."

The near future, notebook designers expected magic number is eight, as the number of working hours a day.

     A few years ago, this is Shexiang, Baidoa laptop battery power-saving technology and raw materials thanks to the eight-hour notebook is already in sight of the trend, if all developed smoothly, three to four years of portable personal computers will double the battery life time , Extended to eight hours.

     Chip maker Intel urgent implementation of the envisaged in the recent or even ask notebook PC manufacturers to speed up the pace of the original time frame will be shortened by two years. Intel's Mobility Group vice president said Mooly Eden, Intel notebook PC manufacturers to request no later than 2008 before the introduction of thin notebook computers, can be a boot for 8 hours in the middle do not have to replace any external inspiron battery.

     This will benefit the majority of the notebook computer users. Battery life notebook computer is considered the most crucial supporter, thus well received by the chip and PC manufacturers attention.

     Intel and other microprocessor companies are very concerned notebook computer market, the price of notebook computer chips are usually higher than that of desktop computer chips, are more profitable. The notebook computer market share growth, accounting for the PC processor shipments by 30%.

     Computer manufacturers to find ways to design and lighter notebook computers, to let all kinds of Latitude C640 battery life notebook computer to play most vividly.

     At present thin notebook computer batteries is the use of the standard four hours, but actual use, not necessarily have to four hours. IDC analyst Roger Kay said: "The standard is the standard four hours, but had to look at the use of notebook computers. In addition, the battery does not necessarily have to use so long, to buy the beginning, perhaps to four hours, but if the As a multimedia notebook computer use, battery life time may be discounted, one-year warranty period approaching, it may be reduced to only 2.5 hours. "

Extended battery life may be improved proceed from the Latitude C840 battery itself.

     Creation Matrix Power devised a method using zinc metal production of alkaline batteries. Intel's mobile technology director Mike Trainor said that this not only battery power than traditional lithium-ion batteries, will not take up more space for notebook computers.

     Matrix's opponents Pionics design of the lithium-ion batteries also have similar performance. Other efforts with industry to develop new batteries, lithium-polymer (lithium polymer) is one of the Inspiron 8000 battery.

Digital cameras are rapidly replacing film cameras, because the traditional camera makers and consumer electronics manufacturers to actively introduce the product, leading to the rapid growth of the market. As high-speed logic laptop battery, CCD image sensor and displays the need efficient electricity supply at the same time, digital cameras in the power management design is very difficult. Of course, the power of space, weight and heat the requirements are very harsh, in order to meet these design requirements, the need for advanced power management IC.

A digital camera may need six or more different voltage to support its work. Including the drive system logic, low-voltage DSP core, the shutter drive, the lens motor, CCD bias, LCD bias and LCD backlight, and so on. Figure 1 shows a typical compact digital camera frame. The first generation of digital camera power supply IC, and is still used in some products, the adoption of a multi-channel PWM controller, with external MOSFET and transformers have multiple camera operates. This hp laptop battery design limitations include the relatively poor efficiency, a large number of external components, and the great size of the circuit, such as. Although the control IC itself is not expensive, but the whole circuit costs remain high, especially when the need for a high-performance MOSFET and transformers to maintain an adequate efficiency in order to save the limited battery life, its shortcomings become more prominent

Over the past few years, because of IC technology improvements, has allowed more functional and integrated power switches. Higher levels of integration, coupled with the more advanced IC packaging technology, creating a new generation of multi-function integrated power supply IC. Such chips can provide all the needs Pavilion ZV5000 battery of digital camera voltage, and also significantly extended battery life, significantly reduced the number of components. Especially prominent is, in many design also omit a transformer. This not only reduces costs, while also saving design time, because the transformer is usually the suppliers are not in stock. Transformer is customized components, needs special orders - standard, finished the ICP were not these problems.

In addition to eliminating the transformer, a new generation of power IC also increased frequency. This will reduce the size of the components, as per second, had a more switching cycles, each cycle need to switch storage of a lower energy. The result is that inductance and reduced filter capacitance, inductance and capacitance will reduce the size. Reduce capacity Pavilion DV4000 battery, the other advantage is that when switching frequency to 500 kHz and above, the filter will be required capacity, small enough to use ceramic capacitors. Ceramic capacitors was certified more reliable than the electrolytic capacitor, and has a very low ESR, is conducive to reducing ripple.

Market research firm Freedonia Group, mobile phones, handheld computers and emerging wireless devices in the next five years will promote the rechargeable battery market growth. Global non-rechargeable lead-acid laptop battery sales from 2006 to 2001 of 10.1 billion U.S. dollars increased to 16.2 billion U.S. dollars. In the United States, rechargeable battery market from 2005 to 2001 of 2.5 billion U.S. dollars increased to 4.2 billion U.S. dollars.

Freedonia, an analyst Ken Long said that the rechargeable battery demand growth is because notebook computers, handheld computers and cell phones and other portable electrical equipment providers. He pointed out that the use of digital cameras and handheld computers, multi-functional large power consumption of electronic products will increase the demand for batteries. Most of these applications use lithium-ion pavilion battery.

Long said that the lithium-ion batteries will be the first choice in many applications products, because such products can provide longer hours of work. However, lithium polymer batteries will also get some market share, because such a flexible batteries, and portable devices can be a special room for production.

Long pointed out that in 2001, 34 percent of the rechargeable batteries are lithium-ion F1739A. In 2005, this figure will increase to 45 percent. Lithium polymer battery market share in 2000 from about 2 percent to 10 percent.

For some low-end power tools and portable electronic equipment of the nickel-cadmium batteries will lose market share. In 2000, nickel-cadmium batteries can Chong Chongdian battery market accounted for 35
% Of the share. By 2005, nickel-cadmium F3172A market share will drop to 16 percent. For low-end phones and handheld consoles nickel-metal hydride batteries will maintain 15 percent market share.

On the Sanyo, Matsushita, Toshiba and Rayovac batteries, and other manufacturers, the main challenge is to create a smaller cell at the same time increase the battery life. Another problem is to reduce the battery charging time.

Early this year, Rayovac announced the I-C3 technology. This technology can be just 15 minutes - End the F2024A charge. The technology to function on a rechargeable battery, charger and not within. In this way, the battery charging time is short and not enough electricity. This rechargeable battery 1,000. However, this battery than the price of non-use of this technology in your cell number.
