CHARGING PHASES

Step 1: Condition check

The charger checks the battery condition and calculates the required

charging parameters.

Voltage Function

0 V to 0.5 V „Error“ LED (18) lights up. Incorrect connection.

0.5 V to 1.5 V „Bad Battery“ LED (10) lights up. Battery defective.

1.5 V to 12 V Charging will start.

12 V to 14 V Trickle charge will start.

14 V to 15 V Battery fully charged. „Full“ LED (11) lights up.

>15 V „Error“ LED (18) lights up.

Step 2: Precharging

The battery is gently charged with a low charging current to return the battery to a

chargeable state.

Step 3: Soft start

The battery is gently charged with a low charging current.

Step 4: Full load charging

The battery is quickly and safely charged at the set charging current.

Step 5: Absorptionsladung

The battery is charged at a current end-of-charge voltage until charging current

no longer flows.

Step 6 Float charge

The charging voltage will be reduced, charging is complete.

Step 7: Monitoring

The charger monitors the battery capacity. Once the battery falls below 12.8 V,

the charger will emit a charging pulse. This maintains the battery’s highest possible

charging level.
