Storage and Safety Precautions
Although charged Lithium-Ion batteries may be left unused for several months,
their capacity may be depleted due to build up of internal resistance. If this hap-
pens they will require recharging prior to use. Lithium-Ion batteries may be stored
at temperatures between -4
°
F and 158
°
F (-20
°
C to 70
°
C), however they may be
depleted more rapidly at the high end of this range. It is recommended to store
batteries within normal room temperature ranges.
Charging Considerations
It is important to consider the environment temperature whenever you are charg-
ing the Lithium-Ion battery pack. The process is most efficient at normal room
temperature or slightly cooler. It is essential that you charge batteries within the
stated range of 32
°
F to 113
°
F (0
°
C to 45
°
C). Charging batteries outside of the
specified range could damage the batteries and shorten their charging life cycle.
