With a charge status of 100%, all bars are indicated on the display

-1-.

Note

♦ With the battery type “standard charge”, parallel operation of

electrical consumers during the charging process is possible.

The charging time is lengthened by this.

♦ Depending on the battery type, the -VAS5903- switches to

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

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

-VAS5903- .

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 rated voltage -

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 charger does not recognize a Battery - A- , when the

battery voltage is less than 2 V:

The display remains unchanged.

The selected battery type and Ampere hours (Ah) are displayed.

Battery - A- charging, ending

– Press the START/STOP -button.

– Remove the charging clamps from the battery terminals.

WARNING

Do not check or charge a Battery - A- when the visual indicator

has »no color or is bright yellow«. Jump starting must not be

used!

There is a risk of explosion during testing, charging or jump

starting.

These Batteries - A- must be replaced.

Caution

“Refresh charging” is not permitted for VW vehicles, because

voltage surges can damage the on-board electronics.

The Battery - A- must always be disconnected from the vehicle

electrical system when using the “Refresh charging” mode.

Caution

Always set the mode that corresponds to the Battery - A- during

the charging process. Refer to the -VAS5903- Operating In‐

structions.

“Refresh Charging” is suitable for wet batteries, which must be

filled with distilled water.

Do not use “refresh charging” mode on maintenance-free wet

batteries.

“Refresh charging (Refr)” mode is only used on Batteries - A- that

are possibly defective (sulfation). The Battery - A- is then charged

to the maximum specific gravity of the electrolyte and the plates

are reactivated (removal of sulfation layer).

Note

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

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

Battery - A- (6 V/12 V/24 V) and begins the charging process au‐

tomatically.

The -VAS5900- begins the “final charging” when the charge level

is approximately 80 to 85 % of the battery voltage. The fourth bar

is indicated on the display -1-. The Battery - A- is now ready to be

used.

Note

A successful “Refresh charge” depends on the degree of sulfation

on the Battery - A- .

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 rated voltage -
