Proper Battery Usage
> For first time usage, please charge the battery for 3 to 4 hours before using the laptop – usually it requires 2 to 3 charge/ discharge cycles before the battery achieves maximum capacity.
> Best practice is to unplug the charger when the battery is full. And plug in charger when battery reaches 20% to 30%.
> Usage time depends on how you are using your laptop. eg screen brightness, number of applications running etc. Average time is around 2 to 3 hours of continuous usage.
> Careful not to short-circuit the battery by placing the terminals in contact with other metal objects.
