The concept of the charging process is explained
based on a 12 V battery.
Diagnosis
Diagnostic function which automatically checks the
battery status and recognises the voltage.
Voltage Function
0 V bis 1.5 V "Error" LED (9) lit. Battery defective.
1.5 V bis 12 V Charging starts.
12 V bis 13 V Maintenance charging starts.
14.6 V Battery fully charged. "Full" LED
(10) lit.
>15 V "Error" LED (9) lit.
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.
SAFETy
FUNcTIONS

to prevent damage to the charger and the battery
or the vehicle:
•
Short circuit (defective battery),
•
incorrect connection (connected with reversed
polarity),
•
