6. When the battery cell voltage reaches 2.37 V/cell the
80% CHARGE light on the front panel of the charger
will light up. The charger then continues to monitor
the increase in charge until it sees no increase, and
then terminates the charging process.
7. The CHARGE COMPLETE light will come on when
the charging process is finished.
8. Unplug the charger AC power cord and wrap
around storage lugs under the left battery cover.
Abnormal Cycle Indicator Light
If the ABNORMAL CYCLE indicator light should come on
during the normal charging cycle of the batteries, it could
indicate any of the following conditions;
• The AC input to the charger was interupted, i.e. local
power failure or charger cable was unplugged or
bumped and power was interupted intermittently.
• A dead cell or cells in either battery would prevent the
charger from sensing enough voltage to complete the
battery charge.
• One or more of the batteries terminal connections loose
resulting in an intermittent incomplete circuit. Figure 2-4. Battery Charger Front Panel.
