Upon initial use (or after prolonged storage period) the battery may require two to three charge/discharge cycles before achieving maximum capacity. If the battery is not going to be used for more than a month, it is recommended that it is removed from the device and stored in a cool, dry, clean place. It is normal for a battery to become warm during charging and discharging. A charged battery will eventually lose its charge if unused, it may therefore be necessary to recharge the battery after a storage period.
