Store battery packs in a dry environment at a temperature between 0°C / 32°F and 30°C / 86°F. The
lower the temperature at which the batteries are stored, the lower the rate of self-discharge.
If you will be storing batteries for a longer period (more than two months),
the battery charge level should be approx. 30 %. To prevent exh aust ive
discharge which wo uld perma nently damage the battery, check the level
