How to replace the battery

Tools: 10 mm wrench or socket (some hold-downs need 12 or 13 mm or an extension), gloves, eye protection, terminal brush. Time: about 15–30 minutes for an under-hood battery; longer if it's in the trunk or under a seat.

1. Park, turn everything off and take the key or fob out of the car.
2. Disconnect the negative (–) cable first, then the positive (+).
3. Remove the hold-down and lift the battery out. Batteries are heavy (often 35–60 lb); lift with your legs.
4. Clean the tray and cable ends. Set in the new battery with the posts on the same sides as the old one.
5. Fit the hold-down, connect positive (+) first, then negative (–). Tighten until the clamps don't twist by hand.
6. If your car has a vent tube on the battery (common for trunk or cabin batteries), reconnect it.
7. Start the car. Some newer vehicles with a battery monitor need a reset or registration after a new battery. Your owner's manual explains it; a parts store or dealer can do it if needed.

Most parts stores take old batteries for recycling and usually refund a core charge.
