Charging Times.

Charging Times.
The estimated time to charge a battery is shown below. The size of
the battery (Ah) and its depth of discharge (DOD) greatly affect its
charging time. The charge time is based on an average depth of
discharge to a fully charged battery and is for reference purposes only.
Actual data may differ due to battery conditions. The time to charge
a normally discharged battery is based on a 50% DOD. Temperature
will also impact charging times. The GENPRO Series features thermal
compensation that automatically adjusts charging profiles to maximize
charging performance.
