Battery FAQs

Common signs include slow or sluggish engine cranking, dim headlights or interior lights, the battery warning light appearing on your dashboard, and electrical accessories not working properly. If your battery is more than 3 years old and showing any of these symptoms, it's worth getting it tested.

Most battery replacements take between 30 minutes and 1 hour. Some vehicles with batteries in awkward locations (under seats or in the boot) can take a little longer. We'll also reset any electrical systems that need it after fitting.

Yes. We offer a free battery health check that tests your battery's voltage, cranking power, and overall condition. Drop in any time during opening hours and we'll test it while you wait.

A typical car battery lasts between 3 and 5 years, depending on driving habits, climate, and your vehicle's electrical demands. Short trips and infrequent use can shorten battery life. Regular testing helps catch a failing battery before it leaves you stranded.
