The average car battery lasts between three and five years. As it nears the end of its life, you will notice the engine cranking more slowly than usual when starting, particularly on cold Cardiff mornings. Dim headlights, a battery warning light on the dashboard and electrical accessories behaving erratically are all signs that the battery's capacity has diminished significantly.
Modern cars place enormous electrical demand on their batteries, from stop-start systems to heated seats, navigation and USB charging. An older battery that worked fine during summer can fail suddenly in winter, when cold temperatures reduce battery output by up to 30 percent. If your car has not started reliably lately or you have had to jump start it more than once recently, it is time to have the battery tested.

We carry a comprehensive range of batteries for cars, vans and SUVs, including stop-start compatible AGM and EFB batteries.
