the battery charger flash in the sequence noted fol-
lowing;
a. First all five (5) LED’s on the face of the charger
flash three (3) times.
b. Then each LED lights in sequence.
c. Then all five (5) LED’s flash three (3) times
again.
4. When ready to charge, the CHARGER ON LED and
the INCOMPLETE CHARGE (25%) LED on the front
panel of the charger will light up, the charger will
then begin to charge the batteries.
NOTE: If the ABNORMAL CYCLE LED comes on and stays
on at any time during the charge cycle, see sub-sec-
tion following about the ABNORMAL CYCLE indica-
tor LED.
5. When the battery cell voltage reaches 2.37 V/cell the
80% CHARGE LED 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.
6. The CHARGE COMPLETE (100%) LED will come on
when the charging process is finished.
7. Unplug the charger AC power cord and stow the
cord in the opening in the battery/charger carrier
(beside charger).
Abnormal Cycle Indicator LED
If the ABNORMAL CYCLE indicator LED 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 interrupted, i.e. local
power failure or charger cable was unplugged or
bumped and power was interrupted intermittently.
• A dead cell or cells in the battery would prevent the
charger from sensing enough voltage to complete the
battery charge.
• One or more of the battery terminal connections loose
or corroded resulting in an intermittent incomplete cir-
cuit
