Q
Product features
This appliance has been designed for charging a
variety of SLA batteries (sealed lead acid batteries),
as mainly used in cars, motorbikes and several other
vehicles. They may be of types e.g. WET (with liquid
electrolyte), GEL (with mit gel-type electolyte) or AGM
(absorbed glass mat) batteries. A special design of
the appliance (also named „three-phase-charging
strategy“) enables the recharging of the batttery to
almost 100% of its original capacity. Connecting
the battery for a long period to the battery charger
is also a good way of ensuring that your battery is
kept in optimum condition.
Q

Q
Select charging mode
You can select different charging modes for charging
different batteries at different ambient temperatures.
In comparison with conventional battery charging
stations, this appliance has a special function for
reusing an empty battery or rechargeable battery.
You can recharge an empty battery/ rechargeable
battery. Safe charging is ensured by means of a
protection function against incorrect connection and
short circuiting. Due to the installed electronics, the
charging station does not begin operation directly
after connecting the battery, but only starts after a
charging mode has been selected.
This avoids sparking, which often occurs when
connecting. The battery charger is controlled by an
internal MCU (Micro-Computer Unit).
Q

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 8lights 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
8goes out and the LED indicator 7
lights up to indicate the present status.
Q
Regenerating/charging
empty (used, overcharged)
12V 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 7.5V ± 0.5 to 10.5V ± 0.5 V.
This pulse charging process is continued until the
battery voltage has increased to 10.5V ± 0.5V.
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 8flashes during
the pulse-charging process.
Q
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“ 6lights up additionally.
Q
Overheating protection
If the appliance becomes too hot during charging,
the power output is automatically reduced. This
protects the appliance from damage.
Q
Maintenance and care
Before you carry out any work
on the battery charger always pull the mains
plug out of the mains socket.
Do not under any circum-stances use solvents
or other aggressive cleaning agents.
The appliance is maintenance-free.
Switch off the appliance.
