21. Extreme temperatures can substantially affect bat
-
tery performance and charging. Cold reduces bat
-
tery capacity and retards charging. Heat increases
water usage and can result in overcharging. Very
high temperature can cause “thermal run away”
which may lead to an explosion or fire. If extreme
temperature is an unavoidable part of an application,
consult a battery/charger specialist about ways to
deal with the problem.
22. An overly discharged battery might need to be cycled
a few times before it can recover fully. If a battery
begins to heat before coming up to a full charge,
it might be necessary to discharge the battery and
recharge it a few times. The charge and discharge
cycle might help the current acceptance of the battery
and facilitate its recovery to a usable condition.
23. Inactivity can be harmful to deep cycle batteries. If
they sit for several months, a “boost” charge should
be given – more frequently in warm climate (about
once a month) than in cold (every 2-3 months).
24. Never store a battery in a discharged state. The
sulfate that forms during discharge can make the
battery impossible to recharge fully.
