These batteries must be replaced.
Special tools, testers and auxiliary items required
• Battery charger VAS 5903 (VAS 5903)
• The battery temperature must be at least 10 °C.
- Turn off the ignition and all electrical consumers.
- Plug in the electrical system connector of the charger. The last selected operation mode is shown on the display. Refer to=> [ Battery Charger 5903 Description ] Battery Charger 5903 Description.
- Using INFO, set the mode of operation that corresponds with the battery.
The symbol - 1 - for standard charge of wet batteries or the symbol - 2 - for standard charge of Gel/Absorbant Glass Mat (AGM) batteries is indicated in the display.
- Set the capacity (Ah) of the battery to be charged with the corresponding button up [Up Arrow] or down [Down Arrow].
- Clamp the red charging clamp + to the positive battery 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 battery terminal.
The charger recognizes the nominal voltage of the connected battery (6 V, 12V, or 24 V) and begins the charging process automatically.
At a charge condition of approximately 80 - 85 %, charging unit begins the final-charging. The fourth bar is indicated on the display - 1 -. The battery is ready for operation.
With a charge status of 100 %, all bars are indicated on the display.
• With the battery type standard charge, parallel operation of consumers during the charging process is possible. The charging time is lengthened by this.
• Depending on battery type, the charger switches over to sustain charging after approximately 1-7 hours. To achieve a 100 % charge status, the battery should remain connected to the charger for that long.
Possible malfunctions and how they are handled:
1 - Displayed voltage does not match the nominal voltage:
- Hold the appropriate button up [Up Arrow] or down [Down Arrow] until the charging process begins.
2 - Displayed battery voltage does not match rated voltage - charging process has already begun:
- Press START / STOP twice.
- Hold the appropriate button up [Up Arrow] or down [Down Arrow] until the charging process begins again.
3 - The charger does not recognize a battery, when the battery voltage is less than 2 V:
The display remains unchanged.
The selected battery type and Ampere hours (Ah) are displayed.
End battery charging process:
- Press START / STOP.
- Remove the black charging clamp - of the charger from the negative battery terminal.
- Remove the red charging clamp + of the charger from the positive battery terminal.
- Pull out the electrical system connector of the charger.
