Audi Workshop Service and Repair Manuals

Visually inspect battery before performing measurements, e.g. no-load voltage, specific gravity of electrolyte or battery load test.

Such inspection is designed to establish:

• ◆ Whether battery casing is damaged.
  A damaged casing can result in electrolyte leakage.
• ◆ Whether battery posts (battery connections) are damaged.
  Proper contact of connections is not ensured if battery posts are damaged. This may then result in cable burn-out and electrical system malfunctions.
