When should you change a battery?

Batteries don’t last forever – and they rarely give you much warning..
Most batteries last around 5 years, but things like short trips, cold weather, and dodgy alternators can wear them out faster. If your car’s been acting a bit lazy lately, it might be time for a check-up before you get caught out.
  • It’s over 3 years old
  • Engine’s slow to start
  • You hear strange clicking sounds when turning the key
  • Dashboard warning light has come on
  • Your electrics (windows, radio, lights) are playing up
  • It died once and you don't trust it anymore (fair enough)

Frequently Asked Questions

Batteries can be a bit of a mystery, especially when they suddenly give up the ghost. Here are some of the most common things we get asked in the workshop (usually when someone's stuck in the car park with a flat battery).

Most car batteries last between 3 to 5 years, depending on your driving habits, the weather, and the car itself. Short journeys and cold starts wear them out quicker.

Slow engine cranking, dim headlights, dodgy electrics, or a dashboard warning light are all signs. If it's clicking instead of starting, that’s a big clue too.

You might get away with it for a bit, but it’s risky. This normally indicates an alternator/charging fault and If your battery dies completely, you’re stuck. It’s best to get it checked before it lets you down.

Yep – swing by and we’ll check your battery’s health for free. It only takes a few minutes and might save you from needing a jump-start in the rain.

In most cases, yes! We can order batteries and have them onsite within an hour in most cases, some we may even keep in stock! Pop the kettle on – we’ll be done before your tea’s cold.

Good question. We’ll run full diagnostics to check if it’s the battery, alternator, starter motor, or something else misbehaving.

e do. Stop-start systems need special batteries, and we can source the right type for most makes and models quickly.

Only if the battery’s the root cause. We’ll never fit one unless it’s needed – if there’s another issue, we’ll tell you straight.

Yes – we make sure all old batteries are disposed of responsibly, so no leaky nasties end up in the wrong place.

You can, but it’s a temporary fix. If your battery’s gone flat once, it’ll likely do it again – best get it checked to be safe. Some newer cars are also sensitive to being jumped and there is the chance of getting it wrong and causing further damage.
