BATTERY, PREPARING FOR CHARGING

Procedure

WARNINGRisk of explosion on discharged battery with "visual indicator". If the "visual indicator" has no color or is light yellow, the battery may not be tested or charged. Jump starting must not be used! There is a risk of explosion during testing, charging or jump starting. The battery must be replaced.

Before the battery charger can be connected, the following preparations are necessary

Note. It is recommended that the battery is charged when installed and connected. This is the only way to ensure the charging current is incorporated into the capacity calculation for the battery monitoring control module -J367-.

Turn off ignition, turn off all electrical components and remove the ignition key.

CONTACT CORROSION

Contact corrosion can occur if incorrect fasteners (bolts, nuts, washers, etc.) are used.

For this reason, only fasteners with a special surface coating are used.

In addition, rubber or plastic parts and adhesive consist of non-conductive materials.

If there are doubts as to whether parts are suitable or not, use new parts.

Note

  1. We only recommend original replacement parts, they have been tested and are compatible with aluminum.
  2. We recommend using Audi accessories.
  3. Damage resulting from contact corrosion is not covered by warranty.
