Completion of Charge (Automatic Charge Only)

When the FULL CHARGE (green) LED is lit, the charger has stopped charging and switched to the Maintain Mode of operation. If the 12V DEEP CYCLE battery type was selected, the CHARGED (green) LED comes on when the battery is charged enough for normal use.

Maintain Mode (Automatic Charge Only)

When the FULL CHARGE (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 battery voltage drops below a preset level, the charger will go back into charge mode until the battery voltage returns to the full charge level, at which point the charger will return to maintain mode. The voltage is maintained at a level determined by the battery type selected.

NOTE: An automatic charge automatically switches between charge mode and maintain mode as necessary. The FULL CHARGE (green) LED will cycle on when the battery is at full charge and off when the voltage drops below a preset level and the charger goes into charge mode. This cycle will continue, and the FULL CHARGE (green) LED will stay on for longer periods of time as the battery becomes more fully charged. This is not applicable in the manual charge mode.

Using the Engine Start feature (model SI-1275A only)

Your battery charger can be used to jumpstart your car if the battery is low. Follow these instructions on how to use the ENGINE START feature.

Follow all safety instructions and precautions for charging your battery. Wear complete eye protection and clothing protection. Charge your battery in a well-ventilated area.

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.

1.With the charger unplugged from the AC outlet, connect the charger to the battery following the instructions given in section 6 (FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN A VEHICLE).

2.Plug the charger AC power cord into the AC outlet.

3.With the charger plugged in and connected to the battery of the vehicle, set the charge rate selector switch to the engine start position.

4.Crank the engine until it starts or 5 seconds pass. If the engine does not start, wait 4 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.

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, move the charge rate selector switch to the OFF position and unplug the AC power cord before disconnecting the battery clips 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.
