Understanding The Three-Stage (Mode 3) Charging
The Three-Stage Charging (Mode 3) 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 current
will slowly reduce. In Float stage, the charger continuously produces
lower constant oat voltage to fully top up and maintain the battery in
a fully charged stage.
The charger will automatically restart the full charging cycle if it senses
anyone of the battery bank is discharged to lower than 12.8V or after
seven days in oat stage to refresh the battery banks.
Understanding The Two-Stage (Mode 2) Charging

The charger will automatically restart the full charging cycle if it senses
