Capacity vs. Operating Temperatures: Above are the changes in capacity for
wider ambient temperature range, giving the available capacity, as a percentage of
the rated capacity, at different ambient temperatures. The curves show the behavior
of the battery after a number of cycles.

IMPORTANT CHARGING INSTRUCTIONS: WARRANTY VOID IF OPENED OR
IMPROPERLY CHARGED. Do not install in a sealed container. Constant under
or overcharging will damage any battery and shorten its life! Use a good
constant potential, voltage-regulated charger. The open circuit voltage of
a fully charged 12-volt battery is 12.8V at 68°F (20°C).
