MAINTAINING A BATTERY
This unit maintains 6 and 12 volt batteries, keeping them at full charge. It is not recommended for
industrial applications.
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 ENGINE START MODE
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 Engine Start mode 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 Engine Start mode, 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. With the charger plugged in and connected to the battery and chassis, press the Mode Selection button
until the display shows ENGINE START - PRESS FOR BATTERY TEST. Wait for message to change
to ENGINE START ON. Wait two more minutes.
3. When the display shows READY, crank the engine until it starts or 5 seconds pass. If the engine
does not start, wait 3 minutes (until the display shows READY) before cranking again. 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.
4. If the engine fails to start, charge the battery for 5 more minutes before attempting to crank the
engine again.
5. After the engine starts, unplug the AC power cord before disconnecting the battery clamps from
the vehicle.
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, the charger is set to one of three states:
• Wait for cranking – The charger waits until the engine is actually being cranked before delivering the
amps for engine start.
• Cranking – When cranking is detected, the charger will automatically deliver up to its maximum output as
required by the starting system for up to 5 seconds or until the engine cranking stops.
• Cool Down – After cranking, the charger enters a mandatory 3 minute (180 second) cool down state.
The digital display will show COOL DOWN xxx SECONDS REMAINING. It starts at 180 and counts
down to 0. After 3 minutes, the digital display will change to READY.
USING THE BATTERY VOLTAGE TESTER
1. With the charger unplugged from the AC outlet, connect the charger to the battery following the
instructions given in previous sections.
2. Plug the charger AC power cord into the AC outlet.
3. If necessary, press the Battery Type button until the correct type is indicated.
4. Read the voltage on the digital display. Keep in mind that this reading is only a battery voltage reading;
a false surface charge may mislead you. Compare the reading to the following chart.
6V Battery Voltage Reading 12V Battery Voltage Reading
6.4 or more
6.1 to 6.3
Less than 6.1
12.8 or more
12.2 to 12.7
Less than 12.2
