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. When charging is complete, disconnect the charger from the AC power, remove the clamp 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 outlet.
5. When charging is complete, disconnect the charger from the AC power, disconnect the negative
clamp, and finally the positive clamp.
6. A marine (boat) battery must be removed and charged on shore.
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 yellow/orange LED will flash. Do not continue attempting to charge this battery.
Check the battery and replace, if necessary.
DESULFATION MODE
Desulfation could take 8 to 10 hours. If desulfation fails, charging will abort and the yellow/orange LED will flash.
COMPLETION OF CHARGE
Charge completion is indicated by the Charged/Maintaining (green) LED. When lit, the charger has
switched to the maintain mode of operation.
MAINTAIN MODE (FLOAT MODE MONITORING)
When the Charged/Maintaining (green) LED is lit, 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.
MAINTAINING A BATTERY
The unit charges and maintains both 6 and 12 volt batteries, keeping them at full charge.
NOTE: The maintain mode technology allows you to safely charge and maintain a healthy battery
for extended periods of time. However, problems with the battery, electrical problems in the vehicle,
improper connections or other unanticipated conditions could cause excessive current draws. As such,
occasionally monitoring your battery and the charging process is required.
