Mistakes of Notebook Battery Maintenance

Notebook computer from the birth of the day, the argument was about the battery never stopped , because of the use of a laptop computer lasting a very important technical indicator , and battery capacity of the notebook determine this important indicator . In the end how to use to maximize battery efficiency , longer battery life then ? Below, we list some people you will always vulnerable to the error : ( without the instructions are for now the most commonly used lithium-ion battery)

1 , first use the dell laptop battery such as dell Inspiron E1705 battery, dell Inspiron 6000 battery(dell 6000 battery), dell Inspiron 9300 battery, dell Inspiron 9400 battery, dell 310-6321 battery, dell 310-6322 battery, dell D5318 battery, dell G5260 battery, dell G5266 battery and dell Latitude CPi battery,, the first three need to charge 12 hours ?

This is totally unnecessary . Because notebook computers have now improved power management circuitry and charging management system , when the battery reached saturation , control circuit will automatically switch to off state, so long as Chong Man on the line, Bing Bushi that you can charge the more longer on the longer Of .

Second , in order to prevent the memory effect , we should run out of power before charging it?

Each charge before the battery discharge is not necessary , but also harmful. As proved : the depth of discharge of the battery will shorten the laptop battery life meaningless , it is recommended when the batteries when used in about 10% can be charged up . Of course, there are still 30% when battery power for more than best to be charged , because the memory effect does exist.

3 , insert the AC when the battery should be seized, and to prevent the repeated charge and discharge it?

I give advice to you is : do not ! Of course, you can take the natural discharge of lithium-ion batteries to refute me, and that the natural discharge of the battery after the power supply access will occur if repeated charge and discharge , and reduce the battery life. I give you " instead of " This is the answer for several reasons :

1 . Now all notebook power control circuit design of this feature : When the battery is 90 % ( such as HP 's most models ), or 95% will be charged , but to achieve this through natural discharge capacity of a time for 2 weeks Month, when the battery is idle for a month or so to fully charge and discharge to maintain the battery 's capacity, this time you should be concerned about is the battery little bit of exercise instead of being idle again after the charge .

2 . Even if the battery "unfortunate "was once again charged , bringing the loss will not be long without the battery than the power drop caused by a large number .

3 . your data than you or your notebook batteries are much more rare , a sudden power failure has not only hurt your notebook , can not restore the data is no time for regret.

Fourth, long-term storage battery is fully charged you need ?

Read the following to clear the table : ( percentage of saturation at the time the relative percentage of the initial value )

Storage Temperature 40% Charge 100% state of charge state

0 degree 98% ( a year later ) 94 % ( one year later)

25 degrees 96% (one year later ) 80 % ( one year later)

40 degrees 85% ( a year later ) 65 % ( one year later)

60 degrees 75% ( a year later ) 60 % ( 3 months later)

Clearly, if long-term storage batteries, dry and cold as much as possible on the environment and let the battery charge remaining 40 % of the best. Of course, the best take the battery out every month with one , can guarantee the good state of preservation battery, not that bad for the loss of damage to the battery power completely .

Two Battery Questions

We often set our sights on price, weight, figure and configuration when we purchase a new laptop. Battery is often ignored. In fact, battery and integral performance of a laptop are inseparable. Battery is as important as CPU, mainboard, hard disk etc. We list the tips and guideline below. Let's get the most of your lithium laptop batteries.

1. How to charge your new replacement laptop battery properly?

Some laptops with lithium-ion batteries use technology of SBS brightness battery system, which can measure battery's life accurately. Although lithium-ion battery has many merits, we still need to master some professional charge method to prolong battery's life and made it maintain long time power supply. Your new laptop battery requires three complete charge/discharge cycles before use and achieving maximum capacity. It means the battery would have to be charged fully and then be discharged fully. Repeat it three times before starting to use the dell laptop battery such as dell Inspiron E1705 battery, dell Inspiron 6000 battery(dell 6000 battery), dell Inspiron 9300 battery, dell Inspiron 9400 battery, dell 310-6321 battery, dell 310-6322 battery, dell D5318 battery, dell G5260 battery, dell G5266 battery, dell Latitude CPi battery,. By this way, battery's internal chemical materials can be activated and its internal chemical reaction can come into the optimal state. After the activation, the battery can be charged and used freely. But the battery will have to be discharged completely once a month so that the battery activity can be released by such deep discharge and battery life can be maintained.

If battery is idle for over 3 months, it is also necessary to conduct 3 cycles of complete charge and dsicharge to ensure that the battery is activated. You must control the charge time commendably when you use a Ni-MH battery. Please remember not to overcharge continually, or it will shorten the battery's life.

Furthermore, Ni-MH battery should be fully discharged before being charged. It also needs three complete discharge/ charge cycles before starting to use it. Most users are used to using Alternating Current instead of a battery for power supply when they use laptops. Actually the battery needs to be used at least once or twice per month to release the battery power completely. Then fully charge the battery with AC power once. Please remember that it is always good for rechargeable batteries to use up the battery power before giving them a full charge. Because the li-ion Battery used by laptop has its own laziness and would lose its activeness when being idle for long time. It needs to be reactivated.

It is suggested to take out the battery from laptop when it uses AC power supply indoor to avoid having the battery get charged frequently. It is also suggested to shut down the laptop so that battery can be fully charged. Do not remove the AC power during charge.

In addition, the power of battery can easily be used up and most laptops have only one battery. For this reason, some manufacturers have developed a fast charge feature that enables the battery to replenish its power at the fastest pace after power draining up. One hour charge can give the battery back over 90% of its power. Why is not 100%? Because frequent fast 100% charge will greatly shorten the battery life. In order to prolong battery life, fast charge will have to be switched to slow charge(namely Constant Voltage charging method) when battery reaches 90% charge.

For a common laptop, the best charge method is to turn off the laptop when its battery is being charged. The charge time will be shortened by 30% by this method.

2.what's the "memory effect" of battery? and how to clean out it?

Ni-cd batteries, and to a lesser extent Ni-MH batteries, suffer from what's called the "memory effect". What this means is that if a battery is repeatedly only partially discharged before recharging, the battery "forgets" that it has the capacity to further discharge all the way down.To illustrate: If you, on a regular basis, fully charge your Battery and then use only 50% of its capacity before the next recharge, eventually the battery will become unaware of its extra 50% capacity which has remained unused. The battery will remain functional, but only at 50% of its original capacity.

The way to avoid the dreaded "memory effect" is to fully cycle (fully charge and

then fully discharge) the battery at least once every two to three weeks. Batteries

can be discharged by unplugging the device's AC adapter and letting the device

run on the battery until it ceases to function. This will insure your battery remains healthy.

To avoid the best way to the memory effect

Welcome to a Laptop Battery specialist
of the Acer Laptop battery   First post by: www.laptop-battery-stores.com


1. When no external power supply, if at the time the work situation for the time being less than the PCMCIA card slot, first proposed in order to remove the card to extend acer BTP-43D1 battery , acer TravelMate 220 battery life.

2. At room temperature (20-30 degrees) for the best of battery temperature, the temperature is too high or too low operating environment will reduce battery life.

3. Can provide a stable power supply in an environment where the use of laptop computers, will remove the battery can be extended by the battery life is simply not true. ASUS notebook computer on, when the full power rechargeable batteries, rechargeable batteries in the circuit will automatically shut down, so will not have been sufficient.

4. Proposed a three-month average of battery power correction action.

5. To minimize the use of the number of Acer BTP-63D1 battery


The number of battery charging and discharging a direct bearing on the life of each charge a battery to retire a step forward. We proposed to make full use of external power supply,

6. The use of an external battery power will be removed.

Some users often several times a day in Plug Power, and notebook computers equipped with a battery, to do so, the greater the damage to the battery. Because each access to external power supply is equivalent to charging a battery, battery on the nature of the Zheshou.

7. Exhausted after the electricity charge and avoid charging time is too long

No matter your notebook to use nickel-metal hydride or lithium-electric power, it must be exhausted before sufficient power (electricity consumption of less than 1%), which is to avoid the best way to the memory effect. Li-electric memory will have the same effect, but its memory effect than Ni-MH small number of them.

8. Note the use of normal


Normally used to prevent exposure to prevent damp to prevent the erosion of liquid chemicals, acer BATCL50L battery , acer TravelMate 290 battery , acer TravelMate 4000 battery to avoid contact with metal objects, such as access to happen.

Laptop battery purchase Notes

The laptop battery life - as no more than 3-4 years, it may be in the process of users are most likely to be replaced. Two years later the use of laptop computers, battery consumption will find more and more rapidly. If possible, can replace the old batteries for new batteries to ensure the stability of the computer work.


When the need to replace notebook batteries, preferably with a selection of models to replace the battery. However, if the old computer is to use nickel-metal hydride batteries, in order for longer battery-powered, of course, can also be specified by the computer user's manual or manufacturer's recommended selection of models of lithium batteries. Although the nickel-metal hydride batteries because of cheap, but there is memory effect, but also in the same capacity next-to-weight ratio of lithium batteries, lithium batteries and have no memory effect, light and power for a long time, and other advantages, has become a laptop acer TravelMate 2300 battery standard . At this stage to use the notebook computer manufacturers of lithium acer Aspire 1680 battery btp-44a3, acer Aspire 1410 battery due to the different power supply in time there are certain gaps and friends in the process of selection should be noted that different brands of batteries in the difference between the best of several brands compare.

In addition to the performance of the battery manufacturers supply a statement of the time, but also pay attention to the needs of its capacity. Battery capacity is usually AH (ampere-hour, ampere hour) calculation of the current notebook computer equipped with the most common is about 4000AH, and ordinary cell can be sustained for more than 2 hours. In addition to the battery power supply by the time the whole Computer power and heat dissipation, and other factors, the screen size (the bigger the more power), screen brightness, as well as the implementation of the work of all time will affect the power supply .

Now the prices of notebook batteries in 1000 up and down the ocean, accounting for about notebooks to 10% of the total price - about some of the ultra-thin models and even higher. The battery warranty, security of 3 months, half a year of security, but also the longest for 1 year; The reason why the battery warranty period is short because the notebook battery supplies belonging to the vulnerable, the frequency of recharging is a constant, A small one. Moreover, the notebook acer LCBTP03003 battery ,acer Aspire 1300 battery and other hardware, there is no room for repairs can only be replaced. For such a long period of warranty products (OZ), were invisible on the increased burden on manufacturers, so the purchase of laptop before the battery must ask the warranty period and conditions.

In addition, the purchase of second-hand laptop when not forget to try its built-in battery can be sustained for a long time and more work. Under normal circumstances, used in 2012 after sufficient power in notebook computers, Ni-MH battery can be some support for the work of the computer about 1 hour, lithium-ion battery can support nearly 3 hours, but relative to the terms of this new battery The request is already very low, less than the battery indicator shows a view from near the end of life.

Notebook Battery of the causes of damage

Laptop acer BTP-APJ1 battery , acer BTP-AQJ1 battery , acer BTP-ARJ1 battery life is longer, often dissatisfied with the necessary and sufficient electricity, and even shows the battery has been damaged, the specific performance of the resistance is bigger in charge at both ends when the voltage rise faster. This charge was easy to control the line has been judged to be filled, the capacity of natural decline. As the larger battery internal resistance, discharge when the voltage drop, fast, so the system can easily mistaken for lack of voltage, less power consumption. Batteries found in the relatively short-time working hours, should take corresponding measures.
