    In float charging normally the load current is supplied from the charger output and battery is fed a low current of 2 to 3 amps depending on the AH capacity of battery.When ac supply fails or charger fails the load is supplied from the battery and when supply is restored if the battery is deep discharged battery is charged in boost mode with higher voltage and current to reach the required AH.
    Normally all chargers are having boost and float capacity it will change to that mode depending on the application or usage automatically or manually depending on the charger.
