Frequently Asked Questions
How long does a car battery last?
Most car batteries last 3–5 years. Short journeys, cold weather, and leaving electronics on while parked drain batteries faster. If your car struggles to start on cold mornings, it's likely time for a replacement.
Can I replace my car battery myself?
For many cars, yes — it's a straightforward job. However, some modern vehicles (especially BMWs and Mercedes) require the new battery to be 'registered' with the car's computer using diagnostic equipment, which requires a garage visit.
