The charger continuously monitors battery temperature. To initiate a charge cycle, the battery
temperature must be within the T
LTF
to T
HTF
thresholds. If battery temperature is outside of this
range, the controller suspends charge and waits until the battery temperature is within the T
LTF
to
T
HTF
range.
If the battery temperature is between the T
LTF
and T
COOL
thresholds or between the T
WARM
and
T
HTW
thresholds, charge is automatically reduced to I
CH/8
(1/8 of the charging current).
