Dim lights or a clicking sound may help guide an inspection without proving the battery is the only problem. The professional assesses whether a starting aid, a compatible replacement or recovery is appropriate. For an electric or hybrid car, say so in the request: the auxiliary battery is separate from the traction battery.
Information to prepare
- Describe sounds and warning lights when you tried to start.
- Provide the powertrain and whether the car has stop-start.
- Say whether the car has been unused for a long time.
- Report swelling, leaks or an unusual smell near the battery.
What to watch for
Avoid improvised cable connections: connection points and procedures differ by model. Do not handle a damaged battery or high-voltage components.
