Keep the battery pack betwee n 0°C and +30°C. T he lower the temperature at w hich

If you will be storing batteries for a longer period (longer than two m on ths),
the battery charge level s hould be appro x. 30 %. To prevent exhaustive
discharge which would permanently dam age the battery, check the level
