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 wh ich t he 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 exhaustive
discharge which would permanently damage the battery, check the level
of charge of the battery at regular intervals.
