    The best way to store any rechargeable battery for a long period of time is to give it a full charge at room temperature. You will also want to charge the battery at least every 6 months. Some manufacturers suggest 3 to 6 months and others 6 to 9 months so I just suggest every 6 months to make it easy.

    Don’t expect your battery to be fully charged when you go grab it a few months later though. Rechargeable batteries lose some of their charge every day and that is the reason you need to put them on the charger every 6 months to make sure that while they are not being used they have a charge in them. So always plan on charging a rechargeable battery before using it if you have stored it for a while.
