Regenerating / charging
empty (used, overcharged)
12 V batteries
The battery charger detects the battery voltage au-
tomatically once the battery charger is connected
to a battery and the charging process has started.
It changes to pulse charging mode if the voltage is
in the range of 7.5 V ± 0.5 to 10.5 V ± 0.5 V.
This pulse charging process is continued until the
battery voltage has increased to 10.5 V ± 0.5 V.
As soon as this state is reached, the battery charger
switches into the normal charging mode that you
selected earlier.
Now the battery can be charged quickly and safely.
Most empty batteries can be charged and used
again using this procedure.

Protective function of the device

If a unexpected situation should occur, such as short
circuiting, battery voltage below 7.5 V, open circuit
or reversed connection of the output terminals, the
charging station deactivates the electronic system
and immediately switches back to basic position to
avoid damage. If you do not activate any settings,
the system will remain in STANDBY mode. With the
inverse connection of the output clamps the LED
display „incorrect polarity / fault"
additionally.
