For permanently sealed batteries, it is not necessary to carry out the above checks.
2. Connection
Warning! The crocodile clamps must be connected to the battery poles in the following order:
- Connect the positive charging lead (red) to the positive terminal post of the battery (marked P or +).
- Connect the negative charging lead (black) to the negative terminal post of the battery (marked N or -).
Note: It is important to ensure that both crocodile clamps are making good contact with their respective terminal
posts.
Then connect the charger to the mains supply. Once the charger is connected to the mains supply, it will sound a
tone for 0,5 seconds and the LEDs on the power panel will light for a short time.
Warning! Always disconnect the charger plug from the mains supply before connecting or disconnecting the
appliance to or from the battery.
3. Reverse polarity
If the crocodile clamps are connected to the battery in reverse polarity, the reverse polarity LED will illuminate. The
battery charger’s warning buzzer will also sound. If this happens, immediately unplug the charger from the mains.
Connect the crocodile clamps to correct battery terminals and then reconnect the charger to mains supply.
4. Charging
When connected to power supply, the charger is working on 12 V slow charging stage by default. Press ”MODE”
button to select the desired charging mode based on the battery to be charged. After connecting to the battery, the
charger will automatically enter charging status. At first, the orange LED of stage 1 will illuminate and the charger is
automatically detecting the battery. The battery charger is now in the standby mode and the ”12V”, ”GEL” and
”POWER” LEDs are illuminated. This is the standard charging mode and if ”START” button is pressed, the charger
switches immediately into the charging mode for 12V DC gel batteries.
If you require an alternative selection, proceed as follows:
Step 1 – Connect the charger to power supply.
Step 2 – Select the desired mode:
”6V, NORMAL/SLOW” ; ”12V, NORMAL/SLOW” ;
”12V, NORMAL/FAST” ; ”12V, DEEP/FAST”
SLOW Max. 1A current charging
FAST Max. 4A current charging
NORMAL indicates a common maintenance free battery, e.g. gel, VRLA, AGM etc.
DEEP indicates a common lead acid battery or calcium battery.
Step 3 – Connect the charger to battery to start charging automatically.
Step 4 – Charging is completed. First, disconnect the charger from the mains supply. Then disconnect the negative
crocodile clamp (black) and finally the positive crocodile clamp (red).
Battery fault
A few seconds after switching on to the operating mode, the LED indicator will illuminate if the following occurs:
A. High battery voltage: > 15 V (12 V battery) / > 7,5 V (6 V battery)
B. Too low battery voltage: 12 V battery: 5-8 V after 1 minute of charging and 8-10 V after 9 hours of charging / 6
V battery: 3,5-5 V after 4 hours of charging
C. Wrong voltage selection: 6 V voltage for a 12 V battery
D. Improper connection of the charger to battery terminals
E. Battery with voltage < 3,5 V (6 V battery) / < 5 V (12 V battery): defective battery that cannot be charged
Under these conditions, the battery charger will stop charging. In the event of A, B or E, the battery may be defective
and we advise you to consult your nearest battery service center. If the problem is attributable to C or D, select
correct voltage and repeat steps 2 and 3 to charge the battery.
