8. When disconnecting the charger, set the charge rate switch and the timer to the OFF position, disconnect
the charger from the AC power, disconnect the negative clamp, and nally the positive clamp.
9. A marine (boat) battery must be removed and charged on shore.
MANUAL CHARGING MODE
When manual mode is performed, the charger will continue to charge and will not shut off. Monitor the
charging process and stop when the battery is fully charged. Not doing so may damage your battery and
result in property damage or personal injury.
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 damage
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. Set the charge rate switch and the timer to the OFF position.
2. With the charger unplugged from the AC outlet, connect the charger to the battery following the
instructions given in the Follow These Steps When Battery Is Installed In Vehicle section.
3. Plug the charger’s AC power cord into the AC outlet.
4. With the charger plugged in and connected to the battery of the vehicle, set the Charge Rate selector
switch to the Engine Start position.
5. Crank the engine until it starts or 5 seconds pass. If the engine does not start, wait 3 minutes 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.
6. If the engine fails to start, charge the battery for 5 more minutes before attempting to crank the
engine again.
7. After the engine starts, move the charge rate selector switch and timer to the OFF position and
unplug the AC power cord before disconnecting the battery clamps from the vehicle.
8. 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.
FAN OPERATION
It is normal for the fan to run while the timer is on. Keep the area near the charger clear of obstructions,
to allow the fan to operate efciently.
12. CALCULATING CHARGE TIME
When you know the percent of charge and the Amp hour (Ah) rating of your battery, you can calculate
the approximate time needed to bring your battery to a full charge.
Example: Amp hour rating = Reserve capacity + 16
2
NOTE: The Reserve Capacity can be obtained from the battery‘s specication sheet or the owners manual.
To calculate the time needed for a charge:
1. Find the percentage of charge needed.
2. Multiply the Amp hour rating by the charge needed, and divide by the charge rate.
3. Multiply the results by 1.25 to nd the total time needed, in hours, to bring the battery to full charge.
4. Add an additional hour for a deep-cycle battery.
