Keep the battery pack betwee n 0°C and +30°C. The lower the temperature at which
the batteries are stored, the low er the rate of self-discharge.
If you will be storing batteries for a longer period (longer than two mon ths),
the battery charge level should be appro x. 30 %. To prevent exhaustive
discharge which would pe rmanen tly damage the battery, check the level
of charge of the battery at regu lar intervals.
To be able to ma ke use of the optimal charging capacity of the batteries, the battery
should be completely discharged and then fully recharged.
If you do no t use the batteries for long periods, rem ove them from the
