For notebook computers, the battery can be said to be a more important part of the future state is directly related to the lack of computer power far in the working ability of the environment, but the battery in the computer does not sting again, is not a part of population consumption, Therefore, related to laptop battery maintenance and reasonable use is frequently discussed topic.  HP Laptop Battery  IBM Laptop Battery 
As now configured Ni-MH battery models have been difficult to see, the universal application of a lithium-ion batteries, lithium-ion battery life cycle is 300-500 times the charge and discharge. But this does not mean that you rarely use the battery can be life extension. Original battery as a physical work environment sensitive to various factors, which lead to cell loss is mainly due to oxidation caused by how the battery internal resistance increases, which is why many users will complain that they fully charged battery in use Why suddenly no power, and that is when the battery off the assembly line after the end of its internal life and with the clock starting on the move, even if you hold the battery department, also only to some extent delay the cell loss rate of only always put the battery side, meaning that the mobile computer but idle talk.
As the battery life is mainly determined by the number of charge cycles, so to avoid the frequent use of the battery should be a fundamental way, that is as far as possible in the Ministry of Environment with the power to use battery-powered

1. New battery charge. Now the popular new battery is charging the new battery 10-12 hours before the three full charge and discharge. You need not actually do so, the reason to charge for 10 hours to fully activate the battery, but now manufactured in the notebook notebook manufacturers to fully activate the battery before.

See you how to use, is often used batteries, or often used external power supply. If long battery, on and as usual, full of take away with it wants, so normal use the battery in one to two years, the different battery cells are different, they are less filling more with longer battery life shorter, to a year or two, buy a new battery on it, reluctant to change the battery on to the computer core city, not too expensive. The effect is very good. But remember, the best is a full, and then put the battery point of doing a re-charge. And not use half of the charge. Can also extend battery life. Mainly that long to use external power supply. Battery, as part of the notebook, but also played the role of mass balance to maintain the book, if the battery and the case is one, or by the use of the best, if installed in the shell yard, you can take it out only to take power supply, but the battery to discharge to 50% of out every three months, discharge, recharge.

2. Charge and discharge techniques. Laptop battery nickel metal hydride or general material is lithium, nickel-metal hydride battery has a memory effect, lithium battery memory effect is significantly smaller and more, but there. Therefore, we use battery power when you try to run out of power after the charge. Recommended every few months on full charge and discharge the battery once, to ensure that the battery performance.

3. To reduce the number of charging and discharging. The number of laptop battery usually 600 times - 800 times or so, rechargeable battery directly affect their life. Therefore, when a certain reduction in the use of battery and external power supply switching frequency.



4. Using an external power supply disconnect the battery when not. In everyday use, we often use an external power supply for the notebook, if not then remove the laptop battery to, it will charge the battery? The fact is, many big brand laptop batteries are taken into account the vulnerability, only less than 95% when battery is automatically charged. Therefore recommended that you put the notebook battery, you can protect your data will not be lost because of a sudden power failure COMPAQ Laptop Battery Dell Laptop Battery .

5. Use the power scheme.

In this case, choose when to choose one for laptop batteries have become an essential part. But as a consumer, the most intuitive is that the number of cell batteries. Most of the notebook computer market standard 8-core, 6-core or 4 core of the lithium-ion battery. One standard 4-cell lithium-ion batteries are often ultra-thin products, but most of these products can choose to have more core number of cells for longer battery life. As for the number of two different batteries for laptops, batteries are generally more than the number of long life.

There are other friends a better understanding of the notebook when in the selection of products will be more focused on the battery "mAh" unit size, "mAh" is a battery capacity of the unit, its Chinese name is mAh. Purchases in general, many of my friends might think mAh battery unit will have a big longer life time. But the reality is not so, the laptop battery can often see "6-core 4400mAh", "4 core 2200mAh" battery nominal value such as the passage of time we believe that directly determine the capacity of 4400mAh or 2200mAh laptop working hours.

But in fact not the case, the real master, a unit of battery capacity should be considered "Wh", its Chinese name "Wh." Of course, "Wh" and the "mAh" is a close relationship with the following formula: Wh ÷ V × 1000 = mAh be noted that the measurement of electrical power consumption of the unit itself should be a power, that is, "Watt."

Since then, we can learn to select the notebook when the battery is not where it should be noted "mAh" but "Wh" and the voltage of a few. For example to speak, is also a 4800mAh lithium-ion battery voltage at 10.8V and 11.1V under different out of life embodied in the ability different, and this different from the "Wh" different. By calculating we can get the following equation:

4800 ÷ 1000 × 10.8 = 51.84 (Wh)

4800 ÷ 1000 × 11.1 = 53.28 (Wh)

It is obvious to see that 4800mAh 11.1V Li-ion battery in the battery life will be more on edge.

Another message from many of the readers I know many of my friends like to win the laptop's battery to use. LEAVE lost laptop batteries and how different desktops with a single purpose in doing so it would not extend their notebook battery life, and even affect their life. The reason is when the lithium-ion batteries in long-term relatively quiescent state, that the battery power when no electricity or less the case, probably only about 6 months time it will completely lose the function of storing energy. But if you insist on winning the battery to use, it should be filled up to 90% of the electricity, and the plastic wrap on a cool place to save.

Method of repair laptop battery
(A) causes damage to the batteryHP Laptop Battery  IBM Laptop Battery

Notebook computer battery a long time, I am often dissatisfied with electricity charge, and even the battery is damaged, the specific performance is larger resistance, the voltage across the charging up faster. This easy to charge control circuit judge to have full capacity will naturally decline. As the larger battery internal resistance, discharge voltage drop, high speed, so the system is easy to mistakenly believe that voltage is not enough power is low. Comparison of the discovery of short battery life, should take corresponding measures.

(B) of the battery refresh program to restore the battery's discharge time

Big brand laptop has a battery refresh program, we can use it to repair the battery. For example: a IBMThinkpad390/262650 based laptop, the distribution for the nickel-metal hydride battery (Ni-Mh) batteries, as usual discharge properly, leading to the battery discharge time is short, only less than 5 minutes, if carrying a laptop to work, then it is very inconvenient, what methods can restore the battery's discharge time?

In response to these circumstances, we can use the IBM has launched a battery refresh program to refresh the batteries, discharge time to recovery, specific methods are as follows SONY Laptop Battery  TOSHIBA Laptop Battery .

(1) the use of AC power to the laptop, the first to ftp://fip. pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe download the IBM provided TP390/390e/390x series laptop battery refresh program.

(2) Restart your computer, press F8 to enter boot menu and select safe DOS mode.

(3) into the directory just download the file, the implementation of the battery refresh program isbr0lww, exe, reading the warning message, insert the floppy disk as required, and then press the Enter key to the implementation of the self-extracting operation.

(4) boot floppy disk with this computer, the screen appears StartingPC-DOS. . . Message.

(5) prompted unplug the AC power, the program will automatically be on the Ni-Mh battery discharge, discharge is completed, the system will automatically shut down.

(6) The battery temperature is high at this time, should not immediately start, after the battery cool for a while, plug the AC power SONY VGP-BPS2 Battery  SONY VGP-BPS2C Battery  .

(7) boot the computer with a floppy disk, the Autoexec. bat file will automatically run the refresh program, and ask the user whether to proceed. Select yes, press the Enter key.

(8) At this point, refresh process began to refresh the battery, the process soon, when the return to DOS prompt A:> when that refresh is complete.

(9) Shut down the computer, and charge the battery until the light turns green so far.

(10) The above procedure is repeated three times to get the best results.

In addition, many lithium battery pack failure is the result of a failure of energy-saving core, this phenomenon can not be avoided. Because each cell batteries can not be completely consistent with the nature, quality and use for a long time some little worse after the beginning of aging, and damaged the whole (in series) if the discharge curve. Interest and ability of the reader can try to open the battery pack, the multimeter's help, you can quickly find the damaged batteries (abnormal voltage). If conditions allow, according to the corresponding parameters of batteries can replace the qualified product.

(C), notebook battery maintenance

1. When no external power supply situation, if the working conditions at the time being less than PCMCIA card slot, it is recommended to remove the card first to extend battery life.   

2. Room temperature (20-30 degrees) for the battery the most convenient working temperature, the temperature is too high or too low, the operating environment will reduce battery life.

3. Can provide a stable power supply in an environment using a laptop computer, remove the battery to extend battery life by not correct. On the ASUS laptop, when the full battery charge, the battery charging circuit will automatically shut down, so the phenomenon of overcharging does not occur SONY VGP-BPS2B battery  SONY VAIO PCG-6C1N battery.

4. Proposal to conduct a three-month average battery power correction action.

Reduce the power supply output voltage 0.5V is not an easy thing, series resistance does not work, because the resistance of the voltage will change with the current size. I use silicon rectifier diodes, to allow more than through the current in the 2A, or hot tube. Silicon Rectifier diode forward voltage drop between 0.7 to 0.5V, just to meet the requirements. Now a plenty of such tubes in the electronics market, price less than 2 yuan. To a different book on the specific situation may be different, the best time to install a digital multimeter Cece hand. Pipe is being connected serially in the power output, and still harder to buy a power plug inserted himself in the notebook. Diode which is not reversed, the book does not work it wants, and then in turn connected on it.
CANON Camcorder Battery JVC Camcorder Battery
In this way, the power output voltage drop is about 0.5V, if the drop too much, the book will switch to battery, if the drop too low, the book will charge the battery, the specific number to you in your own notebook tried to know.

Of course, if your battery is full, this circuit is not necessary, you can not have it connected directly to the power output can be had on the books.

This point, the two issues mentioned at the beginning resolved. It is up to you test results, and estimated book on different results may be different, it is best to first try to take a circuit, so that took 10 innocent money :-)

Finally I wish you good luck! Good use of your Lithium now!

Special Reminder: HITACHI Camcorder Battery PANASONIC Camcorder Battery

In the modified plug when the mistake is most likely to engage in anti-polar (diodes engage in anti-polarity does not matter), so you must double-check, measured with a multimeter, with different colors of wires to connect the positive and negative. I do not know engage in anti-polarity power supply will not burn the books, did not try!
If all aspects of laptop battery

Mentioned above, the lithium battery, the battery in the end points of several books then? We take a look at the general books batteries into nickel-cadmium batteries, nickel hydrogen batteries, lithium batteries of three. Nickel-chromium batteries, since batteries are bulky, heavy weight, small capacity, short life, there are disadvantages such as memory effect has been abandoned the market. Two kinds of lithium and nickel-hydrogen present to the market mainstream, which lithium is small, light weight, large capacity, low memory effect, charging time and short, is that large businesses use. Lithium has two types, one is lithium, the other is lithium ion battery. Lithium problems such as burning, bursting insecurity, was suspended.

If all aspects of laptop battery

Subsequently, after the improved lithium-ion battery, comply with the safe, efficient, convenient standard, and a market-driven, the time of purchase as long as the Note: Li-ion, the sign on it. The nickel-hydrogen batteries, it can be said is in line with the recent advocacy of environmental topics, and this mainly proud of its recycling features in! But there are also shortcomings, such as the charge time is long, weight, capacity, and small defects than lithium. However, the more charge cycles than lithium-ion battery from 400 to 600 times the mean, Ni-MH battery high record of 1200 is very tempting! In fact, the books also determines the price of the battery price books, if we can know the origin of the battery case, price is favorable for the Hom! Japan, Korea, China and Taiwan have produced books in the battery SAMSUNG Camcorder Battery TOSHIBA Camcorder Battery, especially Japan, mostly alone in Taiwan Province on the price of the battery is relatively cheap, the quality of Japan, South Korea is better! Capacity, the unit is mA / pm, recorded as: mAh, mA / time when the leading books of life, of course, the larger the number the better! 4000mah can support 4 hours of flying time, and with long life time known Matsushita Electric, has more than 4500mah battery capacity, should pay more attention to buy!

I often see the discussion of articles for books battery energy, say are some skills, but this is the books like to discuss every aspect of the battery, if the look and make you feel half the experts, then even if an end of the article!

First to look at books from the perspective of saving the battery, as to energy conservation, it is necessary to first know how to avoid cell "aging"! Typically, the battery internal resistance with the use of time as the growth becomes larger and larger, there will be voltage drop mate, system voltage support is not sufficient, resulting in severe shortage of electricity. Over time this will be a vicious circle, seriously affect the battery life books. This was lucky, sometimes your books battery failure will be a failure in a very short period of time, it is a headache! This failure is probably caused by batteries, this mostly occurred in the lithium battery, who are just like the books of the battery flashlight stabbed home as is a composition of one of the batteries, as long as one of a failure, then it will result in the overall series, voltage delay, regarding the scrap it! Therefore, to use electricity during charging, do not use industrial power, as voltage is too large, will affect the discharge curve! Start charging, do not select the fast mode (BIOS setting), battery charging with constant current charging mode, the system load current, avoid the CPU, hard drive, LCD power struggle between the phenomenon. Discharge when the deceleration let CPU, hard disk stops and the screen transferred to the darkest (or closed off), do not run any programs until the laptop automatically shut down to achieve the objective of low current discharge. Also, if you can find in the market, "temperature protection device", then the best of! It can be achieved by adjusting the overall balance, very good battery backup protection devices TOSHIBA Laptop Battery ACER Laptop Battery.

Now more and more people use the notebook as a notebook lithium batteries, one of the main parts of the problems also increases. So how good use of the notebook lithium batteries do? Grasp the main points:

1. To the appropriate charge and discharge current.

2. To minimize the discharge less than the charging or over-discharge.

While the battery is a consumable, lithium-ion battery is no exception. But no one wants to use up the battery fine spirit of God, to what age do not even rattle is finished, no one wants to start his own half dead battery does not pull the living, has been rubbing on it in 2023, makes good sad to realize how the thing about you is not?

Well, get down to business, following the battery began to speak. First explain, only lithium-ion battery HP Laptop Battery.

Appropriate charge and discharge current

General literature and the state standard on lithium-ion batteries on said lithium-ion battery charge current should be between 0.2C to 1C. It is said that the charge current battery capacity, such as your battery is 4AH, then the 0.2C charge current is 0.2X4 = 0.8A, that is the charge current should be between 0.8 to 4A. In general, the charge current at the extent permitted by the smaller the better, rechargeable lithium-ion battery should be a constant current charging the start, in my IBM R31, this current is about 2.8A, equivalent to 0.7C, is charging its own circuit control can not set yourself. Although this indicator does not charge more than the standard requirement, but is actually relatively large, especially when the battery capacity decline for some time after the charge current may be more than 1C. Now the length of time charge notebook users have also become targets regardless of the manufacturers were forced to set such a high charge current.

So first step is to reduce the charge current. I have a friend in the lab, all equipment readily available, on trial with him a bit. Power outlet on the first series resistance try a result, current is reduced, but became intermittent charge, this is not a good thing. Through trial and error, 4 Ohm is a more ideal value, this time around 0.8A charge current is very stable. This is only the current flowing through the machine power connector, battery charge current is estimated to larger, should be slightly larger than 0.2C. Specific to a different machine, this value may be different. Also with the increase in battery voltage, charge current will be reduced, but the decrease rate is small, less than 0.05A. In this charge state, charging circuit seems to not work, the battery indicator light is not bright. Etc. After the battery voltage up to 12.6V, charging circuits came into play and trickle charge the battery into the state, this time does not matter whether the series resistance has been, the charge current is controlled by the charging circuit, the last full charge after the charging circuit automatically end. The charging time is about 5.5 hours, if not resistance, charging time is 3.5 hours or so.

Lithium ion batteries are very delicate, good charge control circuit is required. With this charging method, can reduce the charge current, battery life, while use of the books original charging circuit controls the charge is relatively simple to achieve them, just buy a power plug (that is, from the power supply plug into the notebook kind, the best to buy two, followed by the methods referred to still use one, be of good quality) and a resistor on it, pay attention to big head and little resistance, after all the above are about 2W of power Otherwise, it would be more heat resistance, preferably constant resistance of the wire myself one of the wire resistance and this resistance is independent of temperature. However, this disadvantage is also obvious that, while not charging work with books. In addition, when charging will have a strange phenomenon, I do not write omitted here, and you try to know, Fortunately, this phenomenon into the trickle charge after the state disappeared. To extend the charging time is not a big problem, anyway, before the night began to charge the next day wake up and fully charged, of course, if you are a night owl or a special short sleep time, that is another matter.

Small current charging problem solved, and now discharge problem. In fact, this is difficult, after all, the book is used to work, the discharge current will vary with the working state, the method mentioned here only designed to restore battery capacity of the operation.

Start the machine, set the power management will never go to sleep (standby) and hibernation (hibernate), others are set to the most power-saving mode, including CPU speed, turn off hard disks, turn off displays, while in TP management process Close some unused hardware, such as sound cards, etc., and then open the battery status display window, and allowed to run in the foreground! ! ! Close other programs, in particular, screen savers and other programs that run on time! ! Do not use the machine, do not close the lid, let the battery discharge end (not to discharge the minimum value set to 0, I set up 3%). Display and hard drive shut down, the discharge current is about 0.5A, this is my IBM R31 can be achieved on the minimum discharge current, battery LG Laptop Battery discharge to the minimum value of the machine will automatically shut down after. The discharge lasted for more than four hours, depending on your battery capacity may be different in different, this time is also used to sleep way to send the.

Well, the last to emphasize that the method is not dead, especially discharge, 10 times which can be done once, or else why should the battery? Charge all the best with a small current charge, of course, if the need to use batteries, power cord plugged directly into the notebook on it.

Using this method my battery is now fully up 14 times, the capacity has been maintained in 45 more, the battery design capacity is 43.2, and has come down, but after such a charge and discharge are restored.

Beginning about two points, one appropriate charge and discharge, and second, not to discharge less than the charge, discharge less than the following to see how to solve the problem on the charge it:

To minimize the discharge less than the charge or over discharge

In fact, over-discharge a good solution, not to terminate the discharge limits set too low on it, I have been using 3%  LENOVO Laptop Battery.

Often use batteries may only be a short Shi Jian, such as battery remaining 70%, if the switching power supply, then the battery will Zidong charge, such a loop vanishes, although the battery's Shoumingbushi set to cycle the absolute number of death of, but always it will reduce the battery capacity, lithium-ion batteries have no memory effect reported, but in fact only a relatively low Bale memory effect. Unfortunately, IBM does not provide solutions to discharge less than the charging method, but provides the basis to solve this problem. This is what I found on the R31 may not be suitable for other machines, but the method should also not far off, do not forget after you've tried were posted for all to share.

R31 charging circuit based on the status of the power to decide whether to charge the battery. Power supply output voltage is 16V, within error of plus or minus 0.2V, if the voltage is lower than 15.5V, so not to charge the battery charging circuit, and books can also work, this is the IBM provided the basis for settlement. But the foundation is weak, because the voltage, if less than 15.2V, books will be converted to battery power, even if the power outlet in the books are useless. In other words, we can torment the space is 0.3V.

If you can find a 15.5V, over current 3A switching power supply, then the problem is solved, otherwise please continue to look down IBM Laptop Battery SONY Laptop Battery.

Reduce the power supply output voltage 0.5V is not an easy thing, series resistance does not work, because the resistance of the voltage will change with the current size. I use silicon rectifier diodes, to allow more than through the current in the 2A, or hot tube. Silicon Rectifier diode forward voltage drop between 0.7 to 0.5V, just to meet the requirements. Now a plenty of such tubes in the electronics market, price less than 2 yuan. To a different book on the specific situation may be different, the best time to install a digital multimeter Cece hand. Pipe is being connected serially in the power output, and still harder to buy a power plug inserted himself in the notebook. Diode which is not reversed, the book does not work it wants, and then in turn connected on it.

In this way, the power output voltage drop is about 0.5V, if the drop too much, the book will switch to battery, if the drop too low, the book will charge the battery, the specific number to you in your own notebook tried to know.

We all know that the battery will not charge if the impact would be very time of their life and the use of, then how can the effectiveness of the right to play their best then? Let me show A thin thin for everyone Tao Road to - a very thin very thin (imagine the echo effect of your own ^ ^)

Some equipped with lithium-ion laptop batteries using the battery system such as SBS intelligence technology to accurately measure the battery life, so use of some peace of mind. Although there are many advantages of lithium-ion batteries, but battery life, the power supply last longer, need to master some professional charge method. Laptop Battery camera camcorder battery TOSHIBA Laptop Battery ACER Laptop Battery
Bought a new lithium-ion batteries used for the first time, the need for 3 full charge and discharge, that battery fully charged at least once a power, then power up to do, repeat three times before use. To activate the chemicals inside the battery, the electrochemical reaction inside the battery into the best in the future can be freely used in the charge that is used, but within a month to ensure the battery must be a complete discharge, so depth of discharge can stimulate cell activation performance, battery life plays a key role. If more than 3 months the battery is not used again until the same should also be carried out with a new battery charge and discharge completely 3 times to ensure that activate the batteryACER travelmate 4600 battery Dell INSPIRON 6000 battery.

The use of nickel-metal hydride batteries, which must control the charge time, should be careful not to over-charge frequently, otherwise it will shorten the battery life. In addition, the NiMH battery be fully discharged before charging, the charging should be fully charged before use and in the normal, also requires the completion of 3 full charge and discharge ACER aspire 5560 battery ACER BATBL50L6 battery.

Most users used each time when using a laptop, plug the AC power supply are very rarely use the battery to the notebook computer power supply. In fact, every month should be at least one or two batteries to power, the battery completely run out, connect the AC full-time. Remember this one, for charging batteries will run out again full of power, useful and harmless, because the notebook computer lithium-ion batteries used in certain inertia effect for a long time without loss of activity of lithium ion would need to re-activation APPLE M8403 battery ACER aspire 3000 battery. When the notebook computer using AC power when the room is best to remove the battery so it often is in charge state. Best off when charging laptop, the battery can be fully charged, do not disconnect the power in the charge halfway. Fully charged, should be used within 30 minutes.

In addition, because the battery is easy to run out of power, most of the notebook computer has only one battery, thus, part of the document so that computer manufacturers developed a fast charge feature that allows users to reduce power consumption and the fastest speed available after the additional power . For example, Dell's notebook computer will have ExpressCharge feature, you can recharge in one hour more than 90%. Why not 100%? Because according to the charge and discharge characteristics of lithium batteries, if often charged up to 100%, the battery life on the big shortened notice, so 10% will be back before the slow-fast charge to charge to extend battery Dell INSPIRON 6400 Battery Dell INSPIRON 9400 Battery life.

No such function for ordinary laptops, the best way is to charge off, charge off charge will be 30% shorter than the boot over the charging time.

First, activate the new battery JVC Camera Battery
 



The new notebooks in the first boot, the battery itself should be 3% of the electricity (which is also common practice firms. If you first open the notebook to buy and found that the battery is full, is certainly used by others, a). At this point, you should be the battery exhausted, until the shutdown, and then use an external power charger, charging time must be more than 12 hours, repeated three times, so as to activate the battery completely, can effectively improve the battery SHARP Camera Battery SONY Camera Battery life.

Second, to reduce the number of battery

To minimize the number of battery, this method seems to be some people feel uncomfortable, since bought a battery is not so frequently used, it bought Zuoshen. Having said that, but the number of battery charge and discharge directly to the life of a single battery charge, battery on a step forward to aging. Suggest that you use an external power supply, use an external power supply when the battery removed. Some friends of convenience, often several times a day plug in the power supply, and laptop computers equipped with a battery, do more damage to the battery PANASONIC Camera Battery SAMSUNG Camera Battery. Because each time access is equivalent to an external power supply to charge the battery once the battery life naturally shortens the number.

Third, avoid prolonged charging
Charge after charge Yong Jin and avoid charging time is too long, regardless of your notebook to use nickel-metal hydride or lithium electricity, be sure to fully charge after Yong Jin (power less than 1%), which is the best way to avoid the memory effect . No memory effect on lithium argument, I note in front of businesses irresponsible been misled. Lithium also have memory effect, but it is the memory effect than Ni-MH small number of Bale. And battery charging in the same way, when you charge the battery to the laptop, try to avoid too long, the general control within 12 hours. As for the prevention of exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the battery contacts and metal objects such as notes, not much to mention here also.

Fourth, long-term maintenance of batteries EPSON Camera Battery NIKON Camera Battery not

If you do not use the term laptop batteries, should be conducted each month on a full battery charge and discharge, in order to maintain cell viability. Also, if long-term (over the year) does not use the laptop battery should be charged to 50%, and once a year charge, in order to prevent excessive battery discharge. Charging time may be more effective if the shutdown, but does not require to be shut down.
