Battery (G-Series)
Table 1-4 shows the specifications of the G5312/G7313 battery available from
Chaparral:
A fully charged battery can provide a minimum of 72 hours backup time using all
ranges of DIMM sizes. Replace batteries only with the same type as provided by the
manufacturer. Dispose of batteries according to manufacturer’s instructions.
If you must store the battery for a long time, you should take certain precautions to
ensure the battery has sufficient charge when it is returned to service. The
recommended storage temperature is between +5°C to +25°C. Avoid temperature
extremes exceeding -20°C or +40°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.
