From the birth of notebook computer that day, about battery usage and maintenance of debate has never stopped, because the use of persistent is notebook computer very important technical indicators, and the capacity of the battery to the notebook computer is an important indicator. What use to maximise the battery efficiency and prolong the service life of the battery? Below, we will list for you several everybody often easy to meet without error: (that is now the most commonly used in lithium ion battery) network in many statement is unfounded. Of course, you can to this article also remain sceptical attitude.

This was not necessary. Because now notebook computers have a perfect power management circuits and charging management system, when the battery reaches saturation, the control circuit will automatically switch to break state, now not blunt electric, so as long as full of line, is not to say that the longer you charging can use more long. But the longer you run it doesn’t matter. And no harm, just wasted some time.

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, it is suggested that when the battery use 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 according to the chemical properties of lithium batteries, laptop battery memory effect does exist.

Three, plug in the ac, the notebook 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 “no” answer this reason has the following:
1. Now the 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% will charge, and through the natural discharge to the capacity of the time for 2 weeks and a month, when the battery idle without a month to fully charge and discharge in order to maintain the battery capacity, this time you should care about is the notebook battery should do some exercises (to blunt once electric) not be idle for a long time after the recharging.
2. Even if the battery “unfortunate” was recharging, bring loss also won’t than long time not caused by the battery power down how much larger.
3. Your hard disk data than your laptop battery even your notebooks are precious, suddenly loses power not only on your notebook there is injury, cannot be redeemed data is it too late.

Four, long-term preservation laptop batteries need full of electricity?
See the following table is clear: (percentage of the saturated state of the relative to the initial value of percentage)
Storage temperature 40% charge state 100% charge state
Zero 98% (one year later) 94% (one year later)
25 degrees 96% (one year later) 80% (one year later)
Forty degrees 85% (one year later) 65% (one year later)
Sixty degrees 75% (one year later) 60% (3 months later)
Obviously, if you want to long-term preservation laptop batteries, as far as possible in the environment of low temperature drying and let the notebook 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 battery.

Five, when use as far as possible to prolong the use time of laptop batteries?
1. The notebook screen brightness turn down. Of course, enough is enough, LCD screen but large power consumption, brightness reduce can prolong the use time of laptop batteries.
2. Open the SpeedStep and PowerPlay provinces electric function. Now the 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 prolong the use time of the battery.
3. Use hard disk drive and the speed droop software: such as NERO DriveSpeed, PowerBooster can reduce software such as cd-rom, hard disk drive, such as the speed, and can effectively reduce the work of the notebook.
4. You can use the master lu software to check the details of the laptop batteries.
