Mode 4 „12 V" (14.7 V / 3.8 A)
This mode is used for charging 12 V lead-acid bat-
teries with a capacity greater than 14 Ah under
cold conditions or for charging some AGM (Absor-
bent Glass Mat) batteries with a capacity greater
than 14 Ah.
Press the MODE selection button
mode 4. As you select the desired mode, the
appropriate LED indicator
mediately. If you take no further action, the elec-
tronic control switches on after a preset delay
to begin the charging process. In this mode the
charging current is the same as in "mode 3". If
the process runs without any problems, the LED
indicator lights up, the electronic control

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.
NOTE: The LED indicator

Protective function of the device

As soon as a deviating situation, such as short-circuit,
critical voltage drop during the charging process,
open circuit or reversed connection of the output
clamps, occurs, the battery charger switches the
electronics off and resets the system directly into the
default settings to avoid causing any 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 polari-
ty / fault" lights up additionally.
