Stage 3 Float Charge: Once the battery has reached full charge, the charger voltage is then lowered
and held constant. This prevents over charging the battery and prolongs the life. This stage is often
referred to as a maintenance mode, rather than charging a battery, it keeps an already charged
battery from discharging while providing power to any additional loads connected to the battery,
such as fridges and lights.
Charge Stage Indicators:
When the charger is in the first stage of
charge, the Bulk LED will be flashing
When the charger is in the second
stage of charge, the Abs LED will be
flashing
When the charger is in the maintenance
stage, the Float LED will be lit solid.
When a load is applied, it is normal for
the battery voltage to decrease until
approximately 13.0 Volts, where the
charger will start charging again.
If all lights are illuminated solid, turn
the charger off and inspect all
connections between the charger and
battery to ensure that they are tight.
Then disconnect the battery and check
the DC output fuses.
