ensure the battery has sufficient charge when you return it to service. The
recommended storage temperature is between +5
o
C to +25
o
C. Avoid temperature
extremes exceeding -20
o
C or +40
o
C for any extended period of time. Exposure to
extreme temperatures causes the battery to discharge at a faster rate and can take
longer to take a full charge when it is returned to service. A new battery or fully
discharged battery can take from four to eight hours or more to fully charge.
