The figures listed above assume that the battery is charging at room temperature. If warmer than room temperature, use a slightly shorter
charging time. If colder, use a slightly longer charging time.
The use of constant current chargers to charge sealed maintenance-free batteries is not recommended. Any overcharge will cause dry-
out and premature battery failure. If a constant current charger is the only type available, do not exceed the charge times listed above and
do not continue charging the battery if it gets hot. When charging, never exceed 15 volts for more than 30 minutes.
