Battery Questions
Frequently Asked About Battery Replacement
How do I know if I need a new battery?
Common signs: slow engine cranking, dim lights when starting, clicking sounds, or battery warning light. We can test your existing battery if you're unsure.
Do you handle start-stop systems?
Yes. We have OBD coding capabilities for start-stop vehicles. After fitting an AGM or EFB battery, we reprogram the system as required.
Can I supply my own battery?
Yes. If you provide your own battery, we can fit it for £35–£45 labour. However, the 12-month guarantee only applies to batteries we supply.
How long is a battery replacement?
Typically 30–60 minutes, depending on vehicle access and whether OBD coding is needed. Most jobs are done in 30–45 minutes.
What warranty do batteries have?
We provide a 12-month labour guarantee on all battery work. Battery warranty varies by type (typically 2–3 years) and is covered by the supplier.
Do you cover all 12 areas?
Yes. Battery replacement is available across all our weekend routes: Feltham, Bedfont, Ashford, Sunbury, Kingston, Hounslow, Twickenham, Richmond, Hampton, Hampton Hill, Hampton Court, and Brentford.
