Understanding the Charger Functions
Three-Stage Charging:
The Three-Stage Charging algorithm has a Bulk, then Absorption and then Float sequence.
During the Bulk stage, the battery accepts the maximum constant current from the charger. In
the Absorption stage, the battery voltage is held to constant voltage and the charging will
slowly reduce. In Float stage, the charger continuously produces voltage at a lower level to
fully top up the battery and maintain the battery in a fully charged state.
The charger will automatically restart the charging cycle in Bulk stage if the battery is
discharged to 12.5V. Also, after seven days, the charger will automatically restart the
recharging cycle to refresh the battery.
Battery Type:
Three types of battery setting (GEL, AGM and Flooded) are available. See reference battery
charging voltage as shown:

GEL
AGM
Flooded
Equalize the Flooded Battery:
For Flooded battery type, equalization mode is available. Use the following procedure to
equalize the flooded battery. See also section 5 on setting EQ mode for flooded battery.
DANGER: Explosion Hazard. The flooded battery generates explosive gases
during equalization. Follow all the battery safety precautions listed in the manual.
CAUTION:
Green Pass-Through Mode (AC mode). Battery Charging is in progress.
