DESULFATION MODE
Desulfation could take 8 to 10 hours. If desulfation fails, the display will show
F02
, charging will abort and
the Bad Battery (red) LED will light.
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 an excessive 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.
MAINTAINING A BATTERY
The unit charges and maintains 6V and 12V batteries.
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.
USING THE ENGINE START FEATURE
Your battery charger can be used to jump start your car if the battery is low. Follow all safety instructions
and precautions for charging your battery. Wear complete eye protection and protective clothing.
WARNING: Using the Engine Start feature WITHOUT a battery installed in the vehicle could cause damage
to the vehicle’s electrical system.
NOTE: If you have charged the battery and it still will not start your car, do not use the Engine Start feature,
or it could damage the vehicle’s electrical system. Have the battery checked.
1. With the charger unplugged from the AC outlet, connect the charger to the battery following the
instructions given in Follow These Steps When Battery is Installed in Vehicle.
2. Connect the charger to a live grounded 120V AC outlet.
3. With the charger plugged in and connected to the battery and chassis, press the Rate Selection
button until the Engine Start
LED is lit, and then press the START button.
4. Crank the engine until it starts or 7 seconds pass. If the engine does not start, repeat. Do not crank
during the cool down period (see below). This allows the charger and battery to cool down.
NOTE: During extremely cold weather, or if the battery is under 2 volts, charge the battery for 5
minutes before cranking the engine.
5. If the engine fails to start, charge the battery for 5 more minutes before attempting to crank the engine again.
6. After the engine starts, unplug the AC power cord before disconnecting the battery clamps from the vehicle.
7. Clean and store the charger in a dry location.
NOTE: If the engine does turn over but never starts, there is not a problem with the starting system; there
is a problem somewhere else with the vehicle. STOP cranking the engine until the other problem has been
diagnosed and corrected.
ENGINE STARTING NOTES
During the starting sequence listed above, the charger is set to one of four states:
• Wait for ready – The charger charges the battery for 2 minutes before the Wait for Cranking state.
While waiting for ready, the digital display shows
On
and the engine can be cranked. For severely
discharged batteries, it is not recommended to crank during this time.
• Wait for cranking – The charger waits until the engine is actually being cranked before delivering the
amps for engine start. While waiting for cranking, the digital display shows
rdy
.
• Cranking – When cranking is detected, the charger will automatically deliver up to its maximum output
as required by the starting system for up to 7 seconds.
