FREQUENTLY ASKED QUESTIONS
How long do car batteries last?
Most batteries last 3 to 5 years. Short journeys and cold weather shorten battery life.
Do BMW batteries need registering?
Yes. BMW vehicles need the new battery registered to the car so the charging system works correctly.
Can a bad alternator kill a battery?
Yes. A failing alternator will not recharge the battery while driving. We test both before replacing parts.
Do you fit start-stop batteries?
Yes. Start-stop vehicles need an AGM or EFB battery rated for the system.
Can you test my battery without replacing it?
Yes. We load-test the battery and charging system and only replace what is actually faulty.
