Car battery replacement cost

The average car battery replacement costs $456 – $493 at a repair shop, before taxes and fees. Parts run about $394 – $403 and labor about $61 – $90. AAA prices standard batteries at about $45 to $150 and AGM batteries at $150 to $250 for the part alone, so many drivers pay far less at a parts store or with mobile battery service.

Cost by vehicle

RepairPal estimates for recent model years; your year, engine and trim can change the price.

What the job involves

Replacing a battery takes a few minutes on most cars, longer when it sits under a seat or in the trunk. Many newer cars with start-stop systems use an AGM battery and need the new battery registered with the car's computer.

Warning signs

• Slow cranking, especially on cold mornings
• Battery warning light
• Battery older than about 3 to 5 years
• Swollen case or corroded terminals

What changes the price

• Your vehicle. Parts for trucks, European and luxury models usually cost more, and on some engines the mechanic has to remove other parts first, which adds labor hours.
• Where you go. Dealers often charge 25% or more above independent shops. Most shops bill about $120 to $159 an hour (AAA, citing a 2025 PartsTech survey).
• The parts. OEM (factory) parts cost more than aftermarket or remanufactured parts. Ask which ones the estimate uses and what warranty comes with them.
• Extras. Related parts found during the job, fluids, shop supply fees and sales tax are not included in these averages.

How to pay less

• Many parts stores test batteries and install them for free or a small fee.
• Replace an AGM battery with another AGM; don't downgrade.
• Return the old battery to avoid the core charge.

How to get a fair estimate

• Ask for a written estimate that lists parts, labor hours and the shop’s hourly rate before any work starts.
• Ask whether the quote uses OEM, aftermarket or remanufactured parts, and what warranty comes with the parts and the labor.
• Get a second quote for any repair over a few hundred dollars. Independent shops often charge less per hour than dealers.
• Ask the shop to show you the old part or the reading that proves it failed, and to call you before doing extra work.
• Check for recalls and warranty coverage first: many powertrain, emissions and hybrid parts carry longer factory warranties.
