CHARGING A BATTERY IN THE
VEHICLE
1. Turn off all the vehicle's accessories.
2. Keep the hood open.
3. Clean the battery terminals.
4. Place the charger on a dry, non-
flammable surface.
5. Lay the AC/DC cables away from any
fan blades, belts, pulleys and other
moving parts.
6. Connect the battery, following the
precautions listed in sections 6 and 7.
7. Connect the charger to an electrical
outlet.
8. Select the desired rate.
9. When charging is complete,
disconnect the charger from the AC
power, remove the clamps from the
vehicle's chassis, and then remove
the clamp from the battery terminal.
CHARGING A BATTERY OUTSIDE
OF THE VEHICLE
1. Place battery in a well-ventilated area.
2. Clean the battery terminals.
3. Connect the battery, following the
precautions listed in sections 6 and 7.
4. Connect the charger to the electrical

6. When charging is complete,
disconnect the charger from the AC

7. A marine (boat) battery must be
removed and charged on shore.
NOTE: This charger is equipped with
an auto-start feature. Current will not be
supplied to the battery clamps until a
battery is properly connected. The clamps
will not spark if touched together.
BATTERY CHARGING TIMES
Times are based on a 50% discharged
battery and may change, depending on age
and condition of battery.
AUTOMATIC CHARGING MODE
When an Automatic Charge is performed,
the charger switches to the maintain mode
automatically after the battery is charged.
ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging aborts,
the charger's output is shut off and the
CHARGING
flash. To reset after an aborted charge,
unplug the charger from the AC outlet,
wait a few moments and plug it back in.
DESULFATION MODE
Desulfation could take 8 to 10 hours.
If desulfation fails, charging will abort and
the CHARGING
will flash.
COMPLETION OF CHARGE
Charge completion is indicated by the
CHARGED/MAINTAINING
LED. When pulsing, the charger has
switched to the maintain mode of operation.
MAINTAIN MODE
(FLOAT-MODE MONITORING)
When the CHARGED/MAINTAINING
(green) LED is pulsing, the charger
has started maintain mode. In this mode,
the charger keeps the battery fully
charged by delivering a small current
when necessary. If the charger has to
provide its maximum maintain current for
a continuous 12 hour period, it will go into
abort mode (see Aborted Charge section).
This is usually caused by a drain on the
battery or the battery could be bad. Make
sure there are no loads on the battery. If
there are, remove them. If there are none,
have the battery checked or replaced.
