Rechargeable Battery System Care to Extend the Life of Lithium-Ion Batteries:
WARNING: Do not use battery if you notice a change of shape (lumps), over-heat when charging or if rust or corrosion on the battery connectors is found.
Fully charge Lithium-Ion batteries before beginning to use the battery. Failure to charge battery prior to use will reduce battery life.
Keep Lithium-Ion batteries fully charged when not in use.
CHARGE BATTERY REGULARLY. Charge between each use and a minimum of once every few months. It is important to maintain at least 25% of your battery power when not in use. Failure to do this will result in performance problems and reduced battery life. Never leave Lithium-Ion batteries discharged for long. The batteries do self-discharge and the charge could drop low enough to damage the battery.
