Step 6: Monitoring
Once the battery is fully charged, the
charging process will stop.
Step 7: Maintenance char-
ging
The charger monitors the battery capa-
city. 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 func-
tions
To avoid damage to charger and bat-
tery, the charger will turn off its own
electronic system and will immediately
reset the system to basic settings in the
case of
•
short circuit
•
wrong connection
•
open circuit
•
reversed polarity connection
•
Battery voltage below 3.0 V ±0.5 V
The charger will remain in standby
mode and the display shows the error
indicator.
During the charging process, if the
charger becomes too hot or due to high
ambient temperature, the power output
is automatically reduced. The charger
continues to trickle charge and automa-
tically starts increasing power when the
temperature drops.

The concept of the charging process is
explained based on a 12 V battery.
Step 1: Condition check
The charger checks the battery
condition and calculates the required
charging parameters.
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: Base charge with a
constant current
The battery is quickly and safely char-
ged with a consistent current.
Step 5: Base charge with a
constant voltage
The battery is charged at a constant
charge end voltage until it is fully
charged.
