For notebook computers, batteries can be said to be a more important component, and its performance is directly related to the lack of power in the notebook computer in an environment of the ability to work. The notebook computer batteries in many of the components is also an out-of consumables, it involves the laptop battery maintenance and reasonable use of the forum is often discussed. On the notebook’s battery kept on hold at the time exactly how much more than that to stay in power and whether or not the use of AC when the battery is removed, are not always what a unified answer. I watch a lot of foreign players in the experience, they will sum up the general point of view, for your reference. After reading this article, you will find many of their claims and generally we have received the recommendation of how many there are some differences.

Li-ion battery in a life cycle in general can be 300-500 times take the necessary and sufficient. Therefore, many people believe that as long as the use of batteries so that it can to a certain extent, played a role in extending the battery life. But they overlooked the battery is indeed the physical nature of the original, when the battery went down the end of the assembly line, its internal clock of life began to move about. Therefore, even if you do not have to set aside the battery, lithium battery life of only two to three years will be able to come to an end of. Battery capacity caused by the reasons for the decline is due to oxidation caused by the increase in battery internal resistance. When the cell resistance reaches a certain point, this time even though the battery still be full of electricity, but the battery has been unable to release the stored electricity.

Caused by lithium batteries that the rate of aging by the temperature and time set aside to preserve the state of charge and the decision. I will give a table to illustrate two different factors on the battery capacity.

Forms can be seen by the high state of charge and high temperature accelerated the decline of the battery capacity. Therefore, if possible, try to charge the battery to 40% placed in a cool place to preserve. This will in the long term preservation so that the battery protection circuitry themselves in a state of the work. If the battery is fully charged will be placed under high temperature, so that the battery will cause great damage, the table has seen a 100% charge in 60 ° C to preserve the environment, 3 months after the inspiron battery capacity dropped by 40% . Thus, in addressing how to preserve the batteries on this issue, at the same time we have been led to the focus of another controversy, and that is when we fixed the use of power, whether it is necessary to remove the battery? Until this question is answered in the Let’s first look at the use of fixed-power battery when placed in the computer environment … … at this time due to the laptop charging circuit protection, so that the battery remained at 100% of full capacity, and this When the battery’s temperature at least between 25-30 ° C, if the hot weather, the temperature will be higher, then from the table, you should be very natural to come to a conclusion that is so In fact would do damage to cells, which led to a decline in capacity.

However, despite the use of laptop computers, high temperatures will bring damage to the battery. However, the battery removed, only the use of fixed power, there will still be some danger that dust and moisture will cause some damage to the battery, and laptop computers in order to avoid the use of the environment for all of a sudden power notebook computers may be caused by injury, so In general, manufacturers are warning users not to remove the battery. Of course, such a result can imagine the natural, often because of your battery in such a relatively poor business environment, it will not be long over, then you need to repair the new center to replace the battery, then the benefit The manufacturer is a natural.

Finally, an eye-catching is the focal point of lithium batteries how reasonable charge and discharge the problem. The lithium battery is carried out for the best part of the discharge, rather than fully discharged, and as much as possible to avoid the often complete discharge. Often the battery too low discharge of the battery so that the results can only be scrapped in advance, because if the battery on each unit below 2.5 volts, the battery’s internal safety circuit will be switched on, this time of the battery would be some bad spent. Therefore, in order to avoid the occurrence of such cases, not to save battery power before it’s too completely, but should be stored until a number of electric charge, and again before the first full use of electricity.

All in all, in order not to make your battery’s too early to lose, so in normal use, you should try to abide by the following principles:
A. avoid full discharge, and often for lithium batteries. The repeated and arbitrary charging of the lithium Latitude D610  damage is very small, almost negligible.
B. will need to be set aside to preserve the lithium batteries under the shade, remember not to put the refrigerator. Avoid high temperature on the car, such as long preservation, the battery will charge to 40% after the placement.
C. If you do most of the time in the use of fixed power, remove the batteries placed in the shade.
D. no need to purchase spare lithium batteries for storage, so this is actually a waste of battery.

The battery is used to use, as long as attention to the reasonable use and custody of the way, there is no need for excessive care, it’s as much as possible for it to contribute more masters of the performance is what matters.

We know that cell phones are a source of electrical energy, which is the driving force for cell phones, there is no battery power supply, cell phone is a piece of scrap iron, a high-capacity high-performance batteries, not only to the phone’s range for a long time, but also to protect The phone circuit, making phone for a long time to work efficiently, while likely to cause unexpected damage to the emergence of mobile phones. And our players, the laptop battery performance in the factory, had been determined, the size of its power, performance, good or bad, are determined by the battery itself, in this regard we can not change the man-made, but That does not mean that we get the battery after it is not so. Cell phones are used by the lithium-ion rechargeable batteries, used in the run out of storage capacity, the need to be supplementary power re-charging. You do not look down on the link in charge, a good battery charger and charge the correct way to maintain a long battery standby time, but also to extend battery life. Step further said that mobile phones can also play a role in protection. On how to approach the charge, often in the forum, players will be asked, after a period of time to actually own and use for reference, I summed up the following points:

1. Lithium battery factory in general, manufacturers activated to deal with, and pre-charging, the batteries have more than electricity, to buy a new cell phone battery is a lithium-ion, then the first 3 to 5 times as the adjustment period recharged, should be sufficient for more than 14 hours To ensure that 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. The first charge on this issue, I also consulted with Samsung’s technical staff has given me the answer is that Samsung’s original battery in the factory had already done a full activation of the deal, then do not have to charge long way to activate Lithium-ion activity, for the first time as long as the inspiron battery charge, while the electricity can be filled after use. I would like to Samsung’s technical staff should be able to claim convincing.

2. Some automated intelligent rapid charger when the lights change direction, the fact that only 90 percent full. Charger will automatically slow to change with full battery charge will be. Do not immediately put the charger to cut off power, even the best batteries to power up for some time, and then use the battery is full, or else they will reduce the use of the time.

3. Charging, lithium batteries do not need to discharge, can not discharge, the current production of lithium battery charger is not discharge the function, if you adjust the speed of charge, we charge the proposed slow Chongchong Dian time as far as possible in order to reduce the fast charge Way; whether slow or fast and sufficient time should not charge more than 24 hours. If the battery is likely to be a long time because of the enormous power of the electronic flow and burn batteries.

4. There are a lot of users to charge a mobile phone when driving, in charge of the process, a cell phone because of the use of discharge from outside, because the Latitude D600 battery  charger and power supply inside, is likely to lead to disorder voltage of the cell phone circuit boards Heat will, if the calls would have to return the current moment, the phone’s internal parts damage.

5. The battery life determined by the number of repeated charge-discharge lithium battery charge and discharge in a row could be about 500 or so, after the battery’s performance will be greatly reduced, should be avoided as far as possible within the remaining battery power and then charge the full release End, or charge with the increase in the number of , Battery performance will gradually weaken, the battery standby time is hard not to have dropped.

6. Do not expose the battery at a high temperature or cold, like a dog day weather, cell phones should not be placed under the sun, stood in the scorching sun exposure; or get air-conditioned rooms, air-conditioning on the direct blow. When the charge, the current product back to the battery a little fever is normal.

7. If the cell phone not to place too long, to the best cell phone Latitude D800 battery  to the maintenance department to apply for activation of a deal, their could be a constant voltage direct current, voltage adjustment for the 5 ~ 6V, current 500 ~ 600mA reverse battery connector . Note that the liberalization of touch, up to be repeated three times, after such treatment, re-use original charger “adjustment” charge.

8. The charge is not a good time longer, not for the protection of the circuit full battery charge should be stopped immediately, otherwise they will affect the performance of heat or overheating. Theoretical calculation of battery charging time of the method are as follows: The battery charger power divided by the output current can, for example: a battery 800MAH for electricity, for example, the charger output current 500MA for less time on the same charge 800MAH/500MA = 1.6 hours, of course, this is only theory is full of power time, when the Chargers showed that after the completion of the charge, but also the best battery for about half an hour or so up the power of time. Lithium-ion Latitude CPi battery  charger must be selected precincts, or may fail to saturation, the impact on its performance.

It has always attached great importance to increase the capacity of the lithium-ion laptop battery with a view to the physical size of the smallest battery products to achieve the longest working hours. However, in some applications, longer battery life, more or less the number of rechargeable battery safety is more important than battery capacity. This article describes some can greatly extend the battery life of lithium-ion battery charge and discharge method.

Almost all high-performance portable products that will include the use of lithium-ion polymer batteries, rechargeable lithium-ion batteries because of other rechargeable batteries, lithium-ion batteries have a higher energy density, high battery Voltage, low self-discharge, very long life cycle, and environmental protection, and charging and maintenance simple. In addition, because of its relatively high voltage (2.9V to 4.2V), many portable products can be used single-cell, thereby simplifying product design.

Decided to lithium-ion battery life or service life cycle factors

There is no extend or shorten the battery life of a single factor, and often several factors combined to play a role. On the extension of the life cycle in terms have the following ways to extend battery life:

1. Using part of the discharge. In another pre-charge only 20% or 30% of battery capacity would greatly extend the life cycle. As a general rule, 5-10 shallow discharge cycles equivalent to a full discharge cycles. Even though some of the discharge cycle is likely to be thousands of times, but to keep the inspiron battery at full charge state also shorten battery life. If possible, avoid full discharge cycles (down to 2.5V or 3V, depends on the chemical materials).

2. To avoid the charge capacity of 100%. Choose a lower voltage fluctuations this can be achieved. Reduce voltage fluctuations will increase the life cycle and service life, reduce the cost of battery capacity. Reduce floating voltage 100mV to 300mV can extend the life cycle 2-5 times or more. Compared with other chemical materials, chemical materials for lithium-ion cobalt floating on the high voltage is more sensitive. Phosphate lithium-ion batteries in general than the more common lithium-ion battery float voltage low.

3. Choose the right method to terminate charging. Choose a minimum charge current termination (C/10 or C / x) of the charger, not to charge 100% of capacity, can also extend battery life. For example, the current dropped to C / 5 o’clock and the cycle will be a floating charge voltage of 4.1V down to similar effect. In both cases, the batteries to charge only about 85 percent of capacity, this is the decision of Latitude D600 battery  life is an important factor.

4. Restrictions on the battery temperature. Restrictions on the battery temperature limit can be extended battery life, in particular the ban on below 0 ℃ charge. 0 ℃ in charge following the promotion of the metal plating battery anode on the index, which may cause internal short circuit, batteries and heat instability and insecurity. Battery charger has a lot of battery temperature measuring device to ensure that they are in charge when the temperature limit.

5. Avoid large charge and discharge current, as it would shorten the life cycle. Some chemical materials more suitable for large current, such as lithium-ion phosphate and manganese lithium-ion battery. High-current battery to exert too much pressure.

6. Avoid the 2.5V or lower than 2V the depth of discharge, as this is a rapid permanent damage to the lithium-ion Latitude D800 battery . Possible in-house metal plating enough, it will cause a short circuit, so that the battery is not available or unsafe. Most of the lithium-ion battery in the battery pack has an internal electronic circuit, if the charge when the battery voltage discharge or lower than 2.5V, or 4.3V for more than if the battery is scheduled to exceed current threshold, the electronic circuitry will disconnect the battery connection.

First, it was suggested that the use of lithium batteries for the first time activation should be - must be time to charge more than 12 hours, repeated three times to do in order to activate the laptop battery.
==
This is clearly evident from nickel battery (such as nickel-cadmium and nickel metal hydride) inherited, is not correct. In fact lithium batteries and nickel battery charge and discharge characteristics of a very big difference, and in fact had sufficient discharge will have lithium batteries, in particular liquid lithium-ion battery causing great harm. Therefore the best charge in accordance with the standards of the time and the standard method of charging, that is, in a time of low power consumption prompted charge, and in charge of green light (23 hours in general) do not stop after the charge carried a mandatory charge.

Secondly, the use of a “trickle” charge the charger for the full 95% of the lithium battery “trickle” for 10 hours of slow charge.
==
In fact, the lithium battery in the battery charger will automatically stop after a charge, that is to say, if it is normal lithium powerbook battery, charger is normal, in full, on the charger does not charge, which is in vain The actual waste, and even long-term to do so could damage the battery protection circuit.

Thirdly, the mobile phone charger plugged into a direct, full of power after a long time describing the use of power charger, such as e-books and watch the game, it will not damage the battery.
==
In fact, some mobile phones are batteries, chargers together, not only to the cell phone charger to the battery power supply also, when the current strength of the charger mobile phone power supply, at the same time the use of mobile phones will be battery-powered. For example, playing some of the CPU resources consumed too much of the game will be the case, the use of a certain battery, for example, less than 90% of the electricity, the general charge of the circuit and give mobile phone batteries, which will be frequent in the 90% to 100% Inter-repeated charge to the phone, so the cell phone battery life will be affected.

Fourth, it must run out of power after the cell phone charge, even if it is less than 20% of the power charger will have to get to the office, such as when the electricity charge for the protection of batteries, reducing the number of charge.
==
In fact, advertising in rechargeable 300 or even 500 times 1000 1200, these figures are highly misleading.
In a typical lithium battery, for example, on a lithium-ion M6091  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 discharge of the English abbreviation, in other words, if only 10%, that is, when 90% of the time charge, then charge can be 1000, when used up after charging it can charge 200 times.
It is clear that the number of charge cycles and may be related to depth of discharge, 10% DOD at the time of the cycle than the number of 100% DOD’s a lot longer. 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.
Therefore, under normal circumstances, you should have a reservation in accordance with the remaining 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 insist on the whole time during the day, we should start charging in a timely manner, if you Chargers back to the office to wait for electricity in the end it did not go to work on the road to power using the telephone in such an embarrassing situation to arise but simply to save on the number of battery charge is not worth the considerable. 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.

Fifth, as far as possible to run out of A1012  power, it is best to use rechargeable automatic shutdown.
==
This is obviously wrong, was to avoid memory effect and extend the service life, but lithium batteries do this, over-discharge has been used on the automatic shutdown may be returned to the battery can not be used to activate. A friend of the author’s use of Samsung D908 (the mobile data market evaluation download ringtones) phone, electricity use did not automatically shut down after charging in a timely manner, when three days after the cell phone charger into the phone had been found not start The charge can not be carried out, this is in fact due to the battery as a result of excessive discharge and led to the low voltage that can activate the phone’s charging procedures and conditions of the boot. Solution is simple, universal charger I get on OK on the charge.

Sixth, the cell phone to buy a certain brand batteries business must be original, and to cherish even more the use of batteries, a small charge to reduce the number of prolonging life.
==
This is clearly said that if people do not understand is that the current market, it is true that some countries such as Japan brand of A1078  quality is indeed a lot higher, but the trend from the manufacturing sector, a great number of battery manufacturers in China are concentrated in Guangdong and other places , A number of domestic enterprises in Japan if the batteries are made, even if the quality of its trademarks is reliable, and the price less 50%. In addition, some of the quality of China-made batteries have greatly improved, and if it is not too concerned about capacity, can also be relatively low purchase price of China-made batteries battery.
Finally, I hope you will not deliberately go to the “protection” batteries, as well as hundreds of thousands of dollars relative’s cell phone, more than 10 million dollars of the battery is only a few one-tenth of the price, even if a replacement battery every year and will not become a burden . More importantly, seek to protect the battery and a real need to use the telephone but no electricity is a very embarrassing situation of uneconomical, I believe we all understand this principle.

First, the phone 3-5 times before the charge should be full of first use, should be used to lower power battery warning, is to ensure a full activation of the lithium-ion activity. Lithium-ion laptop 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.

Second, the battery factory, manufacturers have been activated to deal with, the pre-charge to 30% -50%, is also the purpose of the trial to allow cell phone, battery power than is normal at this moment should be re-used power over the full charge , So the cycle three times over. The reason is because the batteries may be in a state of activation of the need to achieve the best.

Third, if the third charge, the battery is still less than nominal value, then the charge current may be sufficient to fully activate the battery (commonly known as electric charge or not charge into the non-saturated), resulting in such a situation may be not to place too long , Or because of the factory failed to make adequate activation (activated) to deal with. This time can be filled with full charge can be activated several times. Can also be activated to make a deal with the battery (or increase “counter-current” to give activation). To do so with constant voltage direct current, voltage of 5-6V, current 500-600mA reverse battery connection. Note that the liberalization of touch, up to repeat three times, we can, through this deal after no problems.

Fourth, the current battery charging circuit protection, battery charging time is usually “× charge current charging time (an hour units) × 0.8 = battery power” formula. For example, 1350mha (milliamperes) of the XV6700 powerbook battery, charger current of 1A (1000 mA) rapid charger, it takes about 1 hour 41 minutes (1.69 hours), of course, this value is based on the battery and charger are Correctly marked on the basis of this, a great number of non-well-known brand of battery, the capacity of some false standard of the other characteristics of the battery itself is also different, the only reference.

Fifth, the battery life determined by the number of repeated charge-discharge capacity X-weighted value, the quality of some of the batteries is not particularly good, if electricity is enough to compare the repeated re rechargeable, it will shorten the life of a big fight. To avoid battery power than when the charge, which will shorten the battery life.

Sixth, when unused for a long time, the battery should be put END electric charge over again. This is because the lithium M8511 battery  cell to place some time after entering hibernation at this time of the normal capacity of less than full power after the actual shortage of electricity. Is the need to re-activate. Lithium batteries are easy to activate, as long as 3-5 after normal time of the charge-discharge cycle of the battery can be activated, the resumption of normal capacity. Lithium batteries very nature of its decision almost no memory effect.

The new battery-activated
Does not need batteries for 10 hours to charge the battery-activated activity, in accordance with the normal charge-discharge method to activate.

The proposed methods: Based on the information available indicates that the  Toshiba Tecra 8100B battery  should be activated in the factory completed, the notebook battery factory with a bit of electricity to avoid natural wear and tear caused damage to the battery. The battery should be activated in the absence of the protection circuit of manner, with its own lithium battery circuit protection circuit, this circuit is designed to avoid over-charging and discharging of the battery, battery in a general, the charging indicator light to turn off time , On the battery charge is not into power, then you plug in the power plug on the face of rechargeable batteries to carry out what is the use? From the battery will be able to see the situation on the  Apple M7426 battery charge there, and teach you a simple way to be able to determine there is no battery during charging, the battery will have time to heat, when the battery is full after an hour (power Do not pull the plug), then you try the battery to see if the battery does not heat hot yet? The results must be cold, not because the battery charge and discharge status, of course, not heat. Notebook makers in the factory when the proposed new battery for more than 10 hours. This author’s view is that notebook makers should be taken into account some new users to use a new HP laptop battery when not fully grasp the skills of charge, simply let them charge 10 hours, so it should be the business expediency.

How to charge

Most people said that the use of unnecessary re-charge automatically shut down, it is not free of charge. When the batteries are generally used in the computer prompts the need for re-charging charge, of course, prompts the time set, the default is 3%.

The author of the proposed method with the majority of people is the same as that. In fact, regardless of the use of laptop power lithium or Ni-MH battery, these batteries have been the memory effect, Ni-MH ,Dell Latitude D810 battery  has a memory effect is obvious, but the lithium power will be the same memory effect, but its memory effect than Ni-MH only a small number of . Lithium is no power on the memory effect that no more than exaggerated advertising business irresponsible behavior is totally misled. Since then the battery has a memory effect, that the charge should be noted that when, as far as possible and then run out of charge, but there is no need to deliberate must say that the computer automatically shut down, so did not use up any harm (as with a notebook battery charge Discharge protection, the general notebook automatic shutdown is less than the standard battery discharge protection), but you do not feel so tired? In fact, less than 3% of the charge in this way on the good, there will certainly be the effect of memory, compared with the natural wear and tear, nothing should be. As for the charge, saying that they want to charge the point of view, I totally do not agree, I have already mentioned the notebook battery, whether or lithium nickel hydrogen power, it has a memory effect, in accordance with this approach if it will go a long way to shorten  Apple A1148 battery life.

Unplug the external power supply when the ibm FRU 92P1141 battery 

Most people in the use of an external power supply, the battery will be removed, use only a small number of external battery power when it is placed on top of their brand names are used in a number of international brands.

In fact, the battery is removed, the conflict focused on the use of an external power supply when the battery is charging up the issue. To know that the number of battery charging and discharging a direct bearing on the life of the general set of lithium Toshiba Satellite A10  charge and discharge the number of fixed and charge only the number of 400-600, specially to improve the product but also 800 times, once for each charge on the battery Retired to step forward. The first point of view is nothing but fear the use of power, the battery will charge on top, not only to increase the number of charge and will have sufficient cause. The second view battery on a computer using an external power supply when it will no longer charge.

In fact, these two viewpoints has its right side, but also the wrong place. This is because the views expressed by individuals, not a very comprehensive investigation after the author, many notebook manufacturers are taking into account the vulnerability of the Pavilion dv8000  battery  and products to add to the protection of battery technology, and therefore different from the corresponding brand notebook batteries Charge of the protection of different technologies, such as some large companies in this area very well, such as: IBM, Hewlett-Packard, Toshiba, Compaq and so on. One of the most thoughtful consideration is IBM, IBM laptop battery discharge can detect the situation, ThinkPad notebook battery power only less than 95% of the time will automatically charge. This battery can play a good role in the protection, quite a number of other companies have to follow. Therefore, such as batteries, you do not need to use the time to pull down, because only when less than 95% of electricity when it will charge. But even then, if you are using the computer for a long time, or the battery will be removed to better notebook for a long time because the heat generated when running on battery to a certain extent of the injury. However, some other “brand” of notebook batteries, may not enjoy such treatment because it has not done inside the  , ibm ThinkPad Z61p battery  protection technology. I like to use a certain brand of notebook computer, a battery on top in the use of an external power supply certainly have to charge about electricity, because the battery when the store will have wear and tear can not be 100%, and as long as it is not 100% , Connected to the power supply on the charge. Every time an external power supply on access to the equivalent of battery time, although only a small charge will be the time. Therefore, we proposed the use of the time according to their own machine case may be, look at notebooks statement, choose to use an external power supply when the battery is removed.

China (Continental) group on September 24 announced that it has mass production of lithium-ion battery, and said their worldwide for the first mass production hybrid with lithium-ion battery. Group of the mainland standard lithium-ion batteries will be in the new Mercedes - Benz S400BlueHYBRID hybrid, the car will be held in 2009 in the mid-market Europe.

China said the Group of lithium-ion VGP-BPS5  battery which can help Mercedes-Benz car to reach 100 km only 7.9 liters fuel consumption and CO2 emission per kilometer dropped to 190 grams.

China Development Group’s lithium-ion battery, weighing about 25 kg, the mass production of the factory is located in Nuremberg, Germany, China Investment Group, in which about 3,300,000 euros, the annual output of up to 15,000 Dell battery   to Taiwan.

What is the use of laptop batteries and maintenance of the taboo? Maintenance of notebook batteries in the end not to be pulled out books, out of power if the how to do? If the laptop battery maintenance of good words to use up to how long? See below, it will know. Laptop battery life is longer, often dissatisfied with the charge, or even show damage, it must use some attention to the maintenance tips: Whether you use the laptop’s lithium notebook battery or Ni-MH battery, battery power as much as possible to use the basic And then do charge (less than 5% of electricity), which is to avoid the best way to the memory effect. In fact, the lithium-ion battery has some memory effect, Ni-MH battery is more than just a lot smaller. It should be noted that, however, charge, as far as possible to avoid too much time, the general control within 12 hours. Battery life of notebook batteries, not by the total length of time, but by the charge and discharge to determine the number of times. Here is the notebook maintenance. If the battery will always be loaded to a notebook instead of taking down, even if the machine shut down and remove AC power, the battery would not like to imagine what it has been full of electricity when the state. As the laptop battery in the battery in the integrated control circuit, so even if the computer is shut down when power is power. As the one connected to AC power, rechargeable battery will begin whenever the power turned on or off, your laptop battery will be recharged repeatedly and discharge affect battery life. To this end, the use of external AC power supply when it is best to unplug the battery, or notebook battery for a long time in a state of fever have an impact on their life. To maintain the battery, do not have long-term, at least 12 months a red discharge in order to ensure its activity. In the custody of the battery when there is a need to pay attention to. At present, the vast majority of notebooks used in lithium-ion battery for a long time, if not in use, often prone to excessive discharge, may no longer be able to charge batteries for notebooks. In order to prevent the excessive discharge, in a state of semi-charge save in cool dry place, and then once every six months, and then the necessary and sufficient electricity to half of the state. In addition, the impact on battery life books of factors including the use of the environment temperature (30 ℃ suggested that the use of the following), storage batteries and the battery temperature suffered shock, such as size. Notebook batteries in use for some time would be after the aging (how maintenance is the same), the specific performance of the resistance is bigger in charge when both ends of the voltage rise faster, so that was easy to charge control circuit has been judged to be full of , The natural capacity is lower than before. Notebook battery is a correction to deal with the aging of the pavilion battery effective way to a small number of notebook batteries have the exclusive use of correction software. If your laptop does not discharge the exclusive use of software, so the battery can be in accordance with the following steps for maintenance: ● screen saver will be banned; ● Windows power management in the power scheme will be set to “always open”; ● alarm at the options Card will be “insufficient power warning” is set to 10% of the operation is set to “operate”; ● will be “a serious power shortage alert,” set to 3% of the operation as a “wait”; ● the screen brightness to the maximum; ● confirmation Closed all the windows, and save all the data before work; ● confirmed that the battery charge in more than 80%, pulled out all external power supplies and equipment. Discharge after the end of the notebook will automatically shut down after the power supply will be planted to allow notebook charge, the process can be repeated 2 to 3 times to enable the continued low current battery discharge, which discharge in the state of our day-to-day use is not possible Achieved, the effect of the discharge and those dedicated basically the same software. Q: What kind of notebook can provide a longer Pavilion DV1000 battery  life time? DELL engineers: only low-value CPU frequency is wrong thinking to choose, because the selected components such as LCD can achieve energy-saving, and CPU can be dynamically adjusted according to application frequencies, it can not value the “Ultra Low Voltage.” In comparison, high-capacity battery configuration of the mainstream Centrino notebooks performed well, if conditions allow, can be equipped with the best recommendations of the second block the use of batteries. Usually use the same battery, the time to go out with the original battery. In fact, to buy a piece of notebook batteries are not expensive, you can find those brands are specifically to help manufacturers who wish to purchase. Those manufacturers because there is no pressure on the brand, so prices less than the general. Find out more about the laptop battery problems

Notebook battery maintenance How can we use for a long time? The problem is different to say, many people are confused, probably know that lithium-ion batteries used in the new time of three to

Chong fully discharge the battery to activate, every month to discharge the battery completely red, and so on, but why it has to buy a new back to a time when three times a month and complete discharge Chong Chong discharge, many people

Do not know much about. To this end, finishing the relevant information for your reference.

     The new compaq battery can be put in charge of deep lithium-ion batteries to upgrade the actual capacity of it? In fact, this is meaningless. Can not think of the use of so-called three times before the release of the all-sufficient “activate” what is necessary.

However, we later put in charge of deep marked the capacity of why change it?

Notebook computer lithium-ion batteries used in general management with a chip and charge control chips. The “management chip” in a series of registers, there is capacity, temperature, ID, and sufficient

Xinhua, the number of discharges, and other values. These values are in use will gradually change. “Charge control chips” to control the main battery charging process. Lithium-ion rechargeable battery process is divided into two

Stage, the current phase of the fast charge (when the Armada V300 battery  indicator light yellow) and reduced voltage current phase (the battery indicator light flashes green. Fast charge current stage, and gradually increase the battery voltage to the battery

Standard voltage, then under the control of the chip into the phase of the constant pressure, higher voltage is no longer sufficient to ensure that they are too, along with the current battery of 0 to weaken gradually increased, but the final completion of the necessary and sufficient

Xinhua. In the cell there were statistical power chips, will be recorded through the red discharge curve (voltage, current, time) can calculate the sample battery power, this is what we in the Battery

Information read in the wh. Value. The lithium-ion batteries in use on many occasions, the discharge curve may change if the chip has been no opportunity to once again read out a complete discharge of a song

Line, which calculated the electricity that is not accurate. Therefore, to be

Deep sufficient to put the chip to calibrate the Business Notebook nc6000 battery .

     So as that of notebook computers for use in “a month after the full charge should take a” leading role should be that these amendments to register in improper

Value, making the battery charge control and battery with a nominal capacity of the line with the actual situation. A battery capacity and how to use the time to decide on its own EVO N400c battery  manufacturing of individual differences, rather than

Is to use. A cell more than its rated put the number of red, so be careful and pay attention to how normal and will not extend its life. Therefore, the use of batteries, should not be too deliberate to protect

, In accordance with the normal peacetime use of it.

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 battery determines that laptop’s important indicator. In the end how can we maximize the use of the laptop 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, it is necessary to run out of power before recharging 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 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 compaq 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 battery 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 Evo N600C 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 Evo N610C battery  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.
