DESCRIPTION OF LEDS/FUNCTIONS
CHARGING A LEAD-ACID BATTERY
1. First make sure your lead-acid battery is
a 6V or 12V battery. Do not charge
batteries with different operating
voltages!
2. Disconnect all loads from the battery.
If the battery is installed in a vehicle,
turn off the ignition and any other loads.
Observe the instructions and safety
information of the vehicle to find out
how the vehicle battery should be charged. Modern vehicles are equipped with sensitive electronic parts
and controls that can be damaged if you do not proceed properly!
3. Connect the battery charger to the power supply (100-240 V~/50/60 Hz).
4. Now you can select a function using the mode button (11) . See the next chapter for a description of the
individual operating modes.
5. Then, connect the battery charger to the battery with the correct polarity. If the polarity is not correct, LED 5
will be lit.
6. If the Charging loop is in short circuit, LED 6 will be lit.
7. This battery charger is equipped with an automatic memory function, i.e. whenever AC supply is connected, it
starts in last selected mode.
8. After the charging process, disconnect the battery charger from the mains supply.
9. First remove the clamp from the negative terminal and then from the positive terminal.
OPERATING MODES
Mode 1: Winter mode (14.7 V +/- 0.25 V)
•This mode is suitable for all lead-acid batteries (also SLA, gel, and AGM) with a capacity above 25Ah at low
ambient temperature.
•To select this mode, press the MODE button (11) until LED 1 (car and snow symbol) lights up. The
charging process starts automatically (4.5A+/-10%), LED 1 is lit.
•When the battery is fully charged (14.7 V +/- 0.25 V), LED 9 lights up. The device automatically switches to
maintenance charging.
Mode 2: Summer mode (14.4 V +/- 0.25 V)
•This mode is suitable for all lead-acid batteries (also SLA, gel, and AGM) with a capacity above 25Ah at normal
ambient temperature.

Operation
•Operation under adverse ambient conditions must be avoided under all circumstances. Adverse ambient
conditions include: ambient temperatures above 40 °C, flammable gases, solvents, vapours, dust, and relative
humidity above 80 %.
•Do not use the battery charger inside a vehicle. The battery charger must not be used in the vicinity of flammable
substances or gases.
•Ensure that there is sufficient ventilation during operation. Never cover the battery charger or the connected
battery.
•Never charge lead-acid batteries in containers or poorly ventilated rooms. Explosive gases can be generated
during the charging process!
•Keep the battery charger as well as the battery away from ignition sources. Do not smoke while handling the
battery charger or the battery! There is danger of explosion!
•Never operate the device immediately after it has been taken from a cold to a warm room. The condensation
generated can cause malfunctions and there is also the risk of a deadly electric shock!
•Persons (including children) who have insufficient knowledge or experience in using the device or who are
physically, sensorially or mentally handicapped may only use the device under the supervision of a person
responsible for their safety. Children must be kept under supervision and may not play with the device.
•Check the battery voltage before starting the charging process, only 6 and 12 Volt batteries can be recharged.
Notes on rechargeable batteries
•Make sure you observe all safety instructions and charging instructions of the battery manufacturer.
•Before connecting the battery to the battery charger, disconnect the battery from any loads or cables (turn off the
loads first!).
•Always disconnect the ground connection from the battery before disconnecting the positive terminal.
•Disconnect the battery from the battery charger before connecting any loads to the battery.
•When connecting or disconnecting the battery, sparks might be produced. Therefore, make sure there is sufficient
ventilation!
•Observe the polarity when connecting the battery to the battery charger (red charger terminal = positive/+, black
charger terminal = negative/-).
•Lead-acid batteries contain aggressive and corrosive acids. Avoid skin or eye contact with battery fluids! Never
dismantle lead-acid batteries! On skin contact, clean the affected areas thoroughly with water and soap. On eye
contact, rinse the effected eye immediately with clear and cold running water! Then consult a doctor immediately!
•Batteries must not be short-circuited or thrown into fire. Risk of fire and explosion!
