**Most car batteries last three to five years. Short journeys, long periods standing, heavy electrical loads and extreme cold all shorten that. Slow cranking, dimming lights on start-up and needing a jump after a few days standing are the classic warning signs.**

Modern stop-start cars use AGM or EFB batteries, which cost more and often have to be registered to the vehicle's battery management system after fitting. Fitting a plain lead-acid battery to a stop-start car, or skipping the coding step, causes premature failure. Our technicians fit and register to spec.
