- Press the INFO button to select the battery type.
The symbol - 1 - for standard charge of wet batteries or the symbol - 2 - for standard charge of Gel/Absorbent Glass Mat (AGM) batteries is indicated in the display.
- Set the battery capacity (Ah) on the battery to be charged with the corresponding [Up Arrow] or [Down Arrow] button.
- Attach the red charging clamp (+) to the battery positive terminal.
• In the case of vehicles with a start/stop function and an installed Battery Monitoring Control Module (J367), the black charge terminal - must be connected to the body ground. The start/stop system will malfunction if it is connected to the negative terminal on the battery.
- Connect the black charging clamp (-) to the negative terminal on the battery/negative connector.
The (VAS 5903) recognizes the nominal voltage of the connected battery (6 V/ 12 V /24 V) and begins the charging process automatically.

The display remains unchanged.
The selected battery type and Ampere hours (Ah) are displayed.
End the battery charging process
- Press START/STOP button.
- Remove the charger clamps from the battery terminals.
- Disconnect the (VAS 5903).
