How to calibrate laptop battery capacity

Laptop battery is a necessary spare parts. The use and charging, will face the problem of declining battery capacity, which is calibrated the battery problem. Well, there is no need to calibrate the battery, how calibrate the battery?

The answer is yes. Because of this decline was not due to cell aging and is therefore appropriate to make this part of the calibration can restore the lost capacity. But the battery should be regularly calibrated, such as 1 to 2 months time.

Such as Compaq and IBM laptop's own power management in BIOS or a program to provide a battery calibration, so the two brands using friends can according to the prompts. For those who do not provide this feature the brand's users according to the following steps.

The aim is to continuous low current discharge batteries, which discharge state in our daily use is impossible to achieve, as the normal state we may make various changes in current operations up and down.

IBM, SONY machine can detect that the battery capacity before and after the change, other machines can download a program called batterymon to see, you will find, little by little to restore capacity in the. However, here to recall that, if your battery is caused by excessive use of aging, Na this ad-hoc method is also not solve the problem of little use Du no.

This method is also recommended that a friend just to use the new machine hand: General Li battery before use in accordance with this method is best for 2 to 3 times the maximum possible in order to best performance of the battery into position.
