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 GENIUS5 features thermal compensation
that automatically adjusts charging profiles to maximize charging
performance.
