Overcharge protection
Battery charging is prevented by the device. It turns off automatically when the respective optimal
charging level is reached and turns on again when the battery voltage has been lost.
The device works fully automatic. The respective charging status is displayed via the LC display. The
output current of the charger depends on the battery being charged. When the battery is fully charged,
it is displayed with „FUL“ in the LC display. The charger automatically switches to a sustained charge.
It now monitors the voltage of the battery and keeps it at full power. The charger provides a maximum
charging time per charging stage. If this time is exceeded, the charger switches off. This is the case when,
for example, Larger batteries, with higher capacity, which exceed the charging capacity of the charger.
The battery must then be disconnected from the charger.
Note: If the device remains connected to a non-maintenance-free battery over a prolonged period, or if
high ambient temperatures prevail, always check the water level every four weeks at the latest. Observe
the specifications recommended by the vehicle / battery manufacturer. Maintenance mode. If the bat-
tery is exposed to a loss of voltage, the charger automatically switches back on until the battery is fully
charged again.

6 Connecting the charger
The device is ready for use.
The device can be operated on any 230V mains socket that is installed as required.
The use of an extension cable is possible if absolutely necessary. This must be in
Good condition, the length should not exceed 10 meters.
- Make sure that the battery is disconnected from the wiring harness in the vehicle
manufacturer’s logbook must be separated.
- If the battery needs to be removed from the vehicle for charging, remove the serial
connection from the battery (minus).
- Before charging a battery, clean the connections (battery poles).
- Check the polarity of the battery poles. The positive pole (+) usually has a larger pole
Diameter as the minus pole (-).

- Ensure that no battery dust and / or corrosion residues of the battery poles are inserted into
your battery eyes or is inhaled.
- In the case of maintenance - free batteries, follow the battery manufacturer’s instructions.
- Make sure that the charger is not connected to the mains socket.
- In case of negative polarity of the vehicle, first connect the red pole to the positive pole (+),
then the connect the black pole clamp (-) to the negative pole, keep in sequence!
- Do not attach to the carburettor, fuel line or metal clamps.
- Do not place the charger on or above the battery1. Only then connect the charger to a power outlet.
1. The LC display lights up and „Pon“ appears for Power on.
2. Press the „Battery Type Selection“ button until the battery type you require is displayed LCD appears.
These are SLA (Sealed Lead Acid) for WET, MF, nonwoven, GEL batteries. The winter icon (snowflake)
appears when the AGM mode is selected.
3. Press the „Mode“ button to select the desired charging current. Motorcycle Icon = 1A Slow.
Vehicle icon = 4A Fast. For a 6V battery, the charger automatically selects the 1A slow charging current.
4. If the pole terminals are connected incorrectly, the error message „Err“ appears in the display.
The voltage of the connected battery is displayed briefly, then the display shows „Con“ for Conditioning,
checking if the battery is charging. The charging process then starts autonomously.
5. When the battery is fully charged, the display will show „Ful“. When charging is completed, first unplug
the unit from the mains socket, then remove the charging cables from the battery.
Important! If you change the battery connections (ring eye connection on pole terminal connection or
vice versa), always ensure a firm and complete connection with the battery connection. If the connection
is incorrect, „Err“ appears in the display. Correct the connection.
MEMORY .The charger remembers the last selected setting. It starts, if no change is made, with the last
selected charging setting, battery type and charging current. Be careful when changing other types of
batteries, with different capacities, to adjust the settings on the charger.
The charging charge is the charge required to compensate for the self-discharge of the battery. Especially
for batteries which are not used for a long time.
Should the outside temperature fall below 0 ° C, the charger has a winter mode with a special charging
program. This mode corresponds to the AGM mode, but is suitable for all other lead-acid batteries at
low temperatures. This mode is NOT suitable for lithium batteries.
If unusual values (internal resistance) occur during the charging cycle, the charger detects the battery
as defective and displays this in the display.
