Step 1: Condition check
The charger checks the battery condition and calcu-
lates the required
charging parameters�
Step 2: Desulphation (rescue)
•
The charger can rescue most drained batteries
with voltages up to a minimum of 1�5
±
0�5 V�
•
The safety switch does not allow the charger to
start charging if the voltage is below 1�5
±
0�5 V�
•
at a voltage range of 1�5
±
0�5 V to 10�5
±
0�5 V
the charger will initiate pulse charging�
•
If the voltage rises above 10�5
±
0�5 V, the charger
will switch to the previously selected regular
charging mode, which will charge faster and more
safely�
Step 3: Precharging
The battery is gently charged with a low charging
current to return the battery to a chargeable state�
Step 4: Soft start
The battery is gently charged with a low charging
current�
Step 5: Base charge with a constant current
The battery is quickly and safely charged with a
consistent current�
Step 6: Base charge with a constant voltage
The battery is charged at a constant charge end
voltage until it is fully charged�
Step 7: Analysis
once the battery is fully charged, the charging
process will stop�
Step 8: Equalisation charge
If the battery is fully charged and drops to 12�8V
within 2 minutes, another charging process will
begin automatically�
Step 9: Maintenance charging
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�
cHarGInG TIMe
a battery’s charging time greatly depends on its
charge condition, capacity and temperature�
