What Is the Average Cost to Replace a Car Battery?

Replacing a car battery is a routine part of vehicle maintenance, but costs can vary depending on your vehicle, the battery type, and how the service is performed. On average, most car battery replacements range between $150 and $300.

Why the Price Range?

The wide cost range comes down to several key factors:

Battery Type: Standard lead-acid batteries are less expensive than AGM or specialty batteries.
Vehicle Compatibility: Some cars require specific battery sizes or labor-intensive installs.
Brand and Warranty: Batteries with longer warranties or premium branding usually cost more.
Service Channel: Mobile battery replacement often includes delivery, installation, and old battery disposal in one bundled price.

Is Mobile Service Worth It?

Yes — especially if your vehicle is immobile. While mobile car battery services may charge slightly more for the convenience, the price typically includes full service at your location. This can eliminate towing costs and time off work. Mobile car battery replacement is often competitive with shop-based options when you factor in total time and cost.
