Audi A4: Solar Battery Maintainer -VAS6102A-

Solar Battery Maintainer -VAS6102A- Device Description

Solar Battery Maintainer -VAS6102A-

The Solar Battery Maintainer -VAS6102A- supports the vehicle electrical system and prevents the Battery -A- from self-discharging.

The Solar Battery Maintainer -VAS6102A- reaches a maximum voltage of 14.3 V and a maximum charge current of 255 mA.

All chargeable lead- and lead gel batteries can be charged with the Solar Battery Maintainer -VAS6102A-.

The Solar Battery Maintainer -VAS6102A- is connected to the diagnostic connection in the vehicle.

The Solar Battery Maintainer -VAS6102A- has a green LED integrated inside the frame which displays the function being performed. The brighter the LED, the higher the charging current.

It is not possible to overcharge the Battery -A- due to the integrated electronics.

The Solar Battery Maintainer -VAS6102A- is secured on the interior rearview mirror -1-. The bottom rests on the instrument panel -2-.

  Note

The Solar Battery Maintainer -VAS6102A- must not touch the instrument panel completely. Only the bottom edge may be used for support. If it touches completely, the color of the instrument panel could change.

Severely Discharged Batteries

  WARNING

Risk of injury. Follow all warning messages and safety precautions. Refer to → Chapter "Warnings and Safety Precautions".

A Battery -A- is designated as "severely discharged" if the resting voltage is less than 11.6 V.

  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

• Severely discharged Batteries -A- freeze earlier.
• Batteries -A- that have frozen must no longer be used.

  Note

• Batteries -A- that have not been used for a long time will discharge by themselves.
• In severely discharged Batteries -A-, the electrolyte consists almost completely of water, because the acid portion has been greatly reduced.
• Severely discharged Batteries -A- become sulfated, meaning all of the plate surfaces of the Batteries -A- harden.
• The sulfation process may be reversed if a severely discharged Battery -A- is recharged immediately.
• If the Battery -A- is not recharged, the plates will continue to harden, and the ability to accept a charge will decrease. This results in reduction of battery performance.
• Severely discharged Batteries -A- in vehicles must be replaced prior to delivery. Pre-existing damage cannot be ruled out.

Procedure

- Check the Battery -A- resting voltage. Refer to → Chapter "Battery, Charging".

- Charge the Battery -A-:

• Battery Charger -VAS5095A-. Refer to → Chapter "Severely Discharged Battery, Charging with Battery Charger -VAS5095A-".
• Battery Charger -VAS5900-. Refer to → Chapter "Severely Discharged Battery, Charging with Battery Charger -VAS5900-".
• Battery Charger -VAS5903-. Refer to → Chapter "Severely Discharged Battery, Charging with Battery Charger -VAS5903-".
• Battery Charger -VAS5906-. Refer to → Chapter "Battery, Charging with Battery Charger -VAS5906-".
