Conventional negative-earth cars only. Check the manual first; start-stop batteries may need workshop registration.
Wear gloves and eye protection. Switch off, remove the key and follow the manual’s shutdown delay.
Confirm the minus marking, usually black. Disconnect negative, then positive. Never bridge terminals with metal.
Remove the retaining clamp. Batteries are heavy and contain acid. Keep upright; leave damaged cases to professionals.
Clean disconnected terminals. Secure the correct replacement. Connect positive, then negative, following the manual.
Ask the dealer about recycling and required setup. Never bin it. Unsure about fitting? Book workshop help.
