Recharge your battery every few months if not in use. Regular checks can help to maintain the charge level.

When considering these guidelines, individual battery manufacturers may offer specific storage recommendations. Variations in brands and battery chemistry can influence these recommendations. Be aware of any unique safety notices or guidance provided by the manufacturer.
