How much does a car battery cost?
A new car battery typically costs $80 to $235 for a standard flooded battery, or $125 to $320 for an AGM (stop-start) battery, as of July 2026. What you pay depends far more on the battery type and brand tier than on your car's group size.
| Battery type | Typical price | Usually found on |
|---|---|---|
| Standard flooded | $80-200 | Most older cars and vehicles without engine stop-start |
| EFB (enhanced flooded) | $200-235 | Some entry-level stop-start vehicles |
| AGM | $125-320 | Stop-start vehicles and cars with heavy electrical loads |
The single biggest factor is battery type. If your car has engine stop-start, it needs an AGM (or sometimes EFB) battery, and those cost more - a flooded battery is not a valid replacement. After type, price is set by brand tier (value vs premium lines), and only then by size. In fact, some retailers charge a single flat AGM price across every group size.
Budget an extra ~$22 core charge if you do not bring your old battery in (refunded when you return it), and check whether installation is free - it usually is, unless the battery is hard to reach or has to be registered to the car.

Frequently asked
Why does an AGM battery cost more than a regular one?
AGM batteries use a sealed, absorbed-glass-mat design that handles the constant charge-discharge cycling of stop-start systems and deep loads far better than a flooded battery. That build costs more, so AGM typically runs $125-320 versus about $80-200 for a standard flooded battery.
What is a core charge?
A core charge (often around $22) is a refundable deposit added when you buy a battery without trading in your old one. Bring the old battery back and you get the core charge refunded. It also keeps lead out of landfills.
Is battery installation free?
At many auto-parts stores (AutoZone, Advance Auto, and others) basic installation is free when the battery is easy to reach. If the battery is under a seat or in the trunk, or needs to be registered to the car, expect roughly $20-75.
