Note

The Battery - A- temperature must be at least 10 °C (50 °F).

Procedure

– Turn off the ignition and all electrical consumers and remove

the ignition key.

– Connect the -VAS5900- to the power supply. The last selected

mode is shown on the display. Refer to

⇒ “3.2.2 Battery Charger VAS5900 Device Description”, page

32 .

– Set the battery type with the INFO button.

The symbol -1- for “standard charge of wet batteries” or the sym‐

bol -2- for “standard charge of Gel/Absorbent Glass Mat (AGM)

batteries” is indicated in the display.

– Set the battery capacity (Ah) on the Battery - A- to be charged

with the corresponding ↑ button or ↓ button.

– Connect the red charge terminal (+) to the positive terminal of

the Battery - A- .

Note

On 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 when it is connected to the Battery - A- negative

terminal.

– Connect the black charge terminal (-) to the negative terminal

of the Battery - A- /negative connector.

The -VAS5900- recognizes the nominal voltage of the connected

Note

♦ With the “standard charge”, parallel operation of electrical con‐

sumers during the charging process is possible. The charging

time is lengthened by this.

♦ Depending on the battery type, the -VAS5900- switches to

maintenance charging after 1 to 7 hours. To reach a 100%

charge level, the Battery - A- should remain connected to the

-VAS5900- .

Possible malfunctions and how they are handled

1 - Displayed voltage does not match the nominal voltage:

– Hold down the ↑ button or ↓ button until the charging process

begins.

2 - Displayed battery voltage does not match the nominal volt‐

age - the charging process has already begun:

– Press the START/STOP button two times.

– Hold down the ↑ button or ↓ button until the charging process

begins again.

3 - The Battery Charger - VAS5900- does not recognize the

Battery - A- , if the battery voltage is less than 2V:

The display remains unchanged.
