Whether it is a laptop or a mobile phone, the battery gradually becomes less powerful with usage and time.

Allow your battery power to drop to minimum levels before re-charging. If your laptop battery is a lithium ion, then you should not let the battery die before re-charging. This deteriorates the battery life. Charge the laptop while the battery charge remains at 10% to 20%. If you are not using the laptop for a continuous period, it is advised to remove the battery from the laptop. When you buy a replacement laptop charger or an extra one, make sure the new charger is compatible with the voltage requirements and your mains.
