© 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 9 to select
mode 4. As you select the desired mode, the
appropriate LED indicator
5 lights up im-
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
8 lights up, the electronic control
switches on and remains in this state until the
battery is charged. As soon as this point is
reached, the battery charger switches to main-
tenance charging mode. Now the LED indicator
8 goes out and the LED indicator 7
lights up to indicate the present status.
© 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 8 flashes during
the pulse-charging process.
© 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“
6 lights up additionally.
© Overheating protection
If the appliance becomes too hot during charging,
the power output is automatically reduced. This
protects the appliance from damage.
