Free to post. Shops bid blind: they see your car, never you. Buy the part yourself, shops bid on labor only. Already have a quote? Check if it’s fair.What the job involves
The shop tests the battery and charging system, swaps the battery, cleans the terminals and, on many newer cars, registers the new battery with the car computer so it charges correctly.

Easy on most cars. Disconnect negative first and reconnect it last.
Questions drivers ask
How much does car battery replacement cost?
At a typical shop, labor runs $35 to $160 (about 18 min to 1 hr of work), and the battery costs about $120 to $300. That puts most jobs between $155 and $460 total. With SwaxFix you can buy the part yourself and have local shops bid on the labor only.
How do I know if it is the battery or the alternator?
If the car dies while driving or the battery light is on while running, suspect the alternator. If it will not start after sitting, suspect the battery. A shop can test both in minutes.
How long do car batteries last?
About 3 to 5 years. Heat shortens battery life more than cold.
Do I need an AGM battery?
If your car has start-stop or came with AGM, yes. Putting a standard battery in its place shortens its life.
