Tips:
1. Upon initial use (or after a prolonged storage period) the battery may require two to three charge/discharge cycles before achieving maximum capacity.
2. If the battery will not be used for a month or longer, it’s recommended that it is removed from the device and stored in a cool, dry, clean place at about a 50% capacity level.
3. Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant stake of charging up and that will reduce the life cycle of the battery
