Battery, Charging

CAUTION:
- Risk of injury. Observe warning notes and safety precautions.
- Batteries that have a colorless or light yellow visual indicator must not be tested or charged. Jump starting must not be used
- There is a risk of explosion during testing, charging or jump starting.
- These batteries must be replaced.

Special tools, testers and auxiliary items required
- Battery Charger VAS 5903 VAS 5900

NOTE: The battery temperature must be at least 10 degrees C.

- Turn off the ignition and all electrical consumers.
- Plug in the electrical system connector of the charger. The last selected battery type is shown on the display.







- 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/Absorbent Glass Mat (AGM) batteries" is indicated in the display.

- Set the capacity (Ah) of the battery to be charged with the corresponding button "Up" arrowup or "Down" arrowdown.
- Clamp the red charging clamp "+" to the positive battery terminal.
- Clamp 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.

NOTE:
- 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. Displayed battery voltage does not match the nominal voltage - the 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. 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.
