From the birth of notebook computer that day, the debate about the battery will never had stopped, because the use of persistent notebook computer is one of important technology index, and the capacity of the battery determines the notebook computer is an important index. Exactly how to use to maximise the efficacy of battery, extend battery life? Below, we will list for everybody several everybody often easy to meet without error: (that are now for the most commonly used lithium ion Apple A1175 battery)
One, first used batteries, the first three times need charging 12 hours?
This was not necessary. Because now notebook computers have a perfect power management circuits and charging management system, when the battery reaches saturation, control circuit will automatically switch to break state, so as long as full of went, is not to say that the longer you charging can use more long.

Second, in order to prevent memory effect, the electricity use up to charge?
Every time before charging to the battery discharge is not necessary, and it is harmful. Because the practice shows that the depth of the battery discharge will be meaningless to shorten the life of the battery, the proposal when the battery used 10% can charge the. Of course when the battery still have more than 30% of the electricity when had better or don't charge, because the memory effect does exist.
Three, insert the alternating current (ac), the battery off, in order to prevent repeated charge and discharge?
My advice to you is: no! Of course, you can take the lithium ion battery of the natural discharge to refute me, said in the cell natural discharge, if the power supply access will appear repeatedly charging and discharging, reduce battery life. And I give you "don't" the answer reason has the following:
1. Now notebook power control circuit is designed with the characteristic: is that when the battery power reached 90% (such as HP's most type) or 95% would charge, and through the natural discharge to the capacity of the time for 2 weeks and a month, when the battery is unused need not a month or so to fully charge and discharge in order to maintain the battery capacity, this time you should care about is the Apple A1189 battery should do some exercises and not be idle after the recharging.
2. Even if the battery "unfortunate" was recharging, bring loss will not than long time don't cell cause power down how much larger.
3. Your data than your battery even your notebooks are precious, suddenly loses power not only on your notebook there is injury, cannot be redeemed data is regret or too late. To see the full text please login Pai card battery network
Four, long-term preservation battery needs full of electricity?
See the following table was clear: (percentage of the saturated state of the relative to the initial value of percentage)
Storage temperature 40% charge state 100% charge state
0 degrees 98% (one year later) 94% (one year later)
25 degrees 96% (one year later) 80% (one year later)
40 degrees 85% (one year later) 65% (one year later)
60 degrees 75% (one year later) 60% (3 months later)
Obviously, if you want to long-term preservation battery, as far as possible in the environment of low temperature drying and let the battery soc at about 40% is most ideal. Of course, every month best to take out the battery with a time, which can ensure the battery good state of preservation and not let electricity completely loss and damage to the Apple A1322 battery.
Five, when use as far as possible, how to use the note the extension of time?
1. The screen brightness turn down. LCD screen but large power consumption, reduce brightness can effectively extend the use time.
2. Open SpeedStep and PowerPlay provinces such as electric function. Now notebook processors and display chip have reduce the work frequency and voltage in order to prolong the using time function, open the corresponding options can greatly extend battery life.
3. Use hard disk drive and the speed droop software: such as NERO DriveSpeed, PowerBooster can reduce the software such as cd-rom, hard disk drive speed etc.
