Note  
The battery must have a temperature of at least 10 °C.  
– Switch off ignition and all electrical consumers.  
– Connect charger plug to battery charger. The last selected  
type of battery will appear on display.  
– Set battery to respective operating mode with INFO.  
In the display the symbol -1- for „standard charge for wet batter‐  
ies“ or symbol -2- for „standard charge for gel/absorbent glass  
mat batteries“ will appear.  
– Set battery capacity (Ah) of battery for charging using respec‐  
tive button „Up“ ↑ or „Down“ ↓ .  
– Connect red terminal clamp „+“ to positive terminal on battery.  
Note  
In vehicles with start/stop function and battery monitor control unit  
-J367- fitted, black terminal clamp must be connected to body  
earth. Connecting it to battery negative terminal will cause start/  
stop system to malfunction.  
– Connect black terminal clamp „-“ to negative terminal.  
The charger unit recognises the voltage required for the connec‐  
ted battery (6 V, 12 V or 24 V) and initiates the charging sequence.  
At a charge condition of approx. 80 - 85 % the battery charger  
switches to the „final charge“ mode. The fourth bar appears in  
display -1-. The battery is ready for use.

The „service mode“ is suitable for:  
♦ Wet batteries where the magic eye allows charging (magic  
eye black or green)  
The operating mode „service charge (SERV)“ is only used on  
sulphated batteries. The battery is charged at a voltage of  
> 14.4 V. This can result in a partial reduction of the sulphated  
layer. After charging, always check the colour of the magic eye  
before using the battery ⇒ page 6 .
