Automatic Charging Mode 

When an Automatic Charge is performed, the charger switches to the 

Maintain Mode (see below) automatically after the battery is charged.

Completion of Charge 

Charge completion is indicated by the FULL CHARGE (green) LED. When 

lit, the charger has stopped charging and switched to the Maintain Mode 

of operation. If the 12V DEEP CYCLE battery type was selected, the FULL 

CHARGE (green) LED comes on when the battery is charged enough for 

normal use.

Maintain Mode 

When the FULL CHARGE (green) LED is flashing, 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 deter-

mined by the BATTERY TYPE selected.

NOTE: The charger 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 flash for longer periods 

of time as the battery becomes more fully charged.
