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 state.
The charger will automatically restart the full charging cycle if it senses anyone of the battery bank is
discharged to lower than 12.8V (13.3V for Lithium) or after seven days in oat stage to refresh the battery
banks.
Understanding The Two-Stage (Mode 2) Charging
The Two-Stage charging is similar to the Three-Stage charging except there is no oat stage after the
absorption stage. The charger will terminate the battery charging after Absorption.
The charger will automatically restart the full charging cycle if it senses anyone of the battery bank is
discharged to lower than 12.8V (13.3V for Lithium) or after seven days in oat stage to refresh the
battery banks.
