1. Choose the best repair time for laptop
It’s inevitable that laptop battery would age, almost all repair methods are based on the principle of “Deep charge and deep discharge” to ease battery memory effect. But we cannot deny that deep charge/discharge operation does no good to the battery, we just have no better method for that. If battery life only reduces tens of minutes, then you should be cautious to take this action. Furthermore, manufacturers have already optimized battery, and there’s no such saying that auto deep charge/discharge could increase battery capacitance. But it’s hard to master the time when deep charge/discharge is needed. After all, each time the power consumed is different, so suggest you asking help from the professional software BatteryMon (here’s the download address http://www.passmark.com/download/index.htm).
  BatteryMon is little software specially supervising laptop battery, especially for those machines without integrated power management chip and software. No doubt, it helps a lot. The biggest feature of BatteryMon is that it could show discharging curve, and after installation, it would auto run. A battery with good performance must have a very inerratic discharging curve, as the picture shown below, basically, the time to decline a grid is probably the same. If you find very exceptional fluctuation, then it’s quite necessary to carry out “Deep charge and deep discharge” repair to the battery.
