Official U.S. vehicle data. It identifies the vehicle only; battery data comes from our catalogue.

Batteries by vehicle type

Each category uses its own search fields — a semi-truck is not a sedan.

Three ways to identify the right battery

Start from what you have in front of you: the vehicle, its VIN or the old battery.

Decode the VIN

Enter the 17-character VIN to identify make, model, year and engine automatically.

Open Batteries of different sizes with measuring tools

Match the battery you have

Search by part number, BCI group, EN code or dimensions and find equivalents.

Data you can check, not guesses

Battery compatibility errors are expensive: wrong size, wrong terminals or a downgrade from AGM to flooded. That is why every record carries its source and one of these verification levels.

How we source data
  • Verified Confirmed against OEM documentation or a licensed catalogue and reviewed.
  • Documented From a licensed or published source, not individually re-checked.
  • Orientative Derived from equivalent specs. Check size, terminals and ratings before buying.
  • Demo Fictitious sample data for demonstration. Never use it for a purchase.

Beyond cars and trucks

Deep-cycle and auxiliary batteries power a lot more. These tools help you size them.

What to check before you buy a battery

Physical size and terminals

The case must fit the tray and hold-down, and terminal type and polarity must match the cables. BCI group (Americas), EN/DIN codes (Europe) and JIS codes (Asia) describe these.

Technology

Start-stop vehicles need EFB or AGM. Never replace AGM with a conventional flooded battery. Lithium is used mainly for auxiliary and house banks.

Cranking amps (CCA)

Meet or exceed the manufacturer's minimum CCA, and only compare values measured under the same standard (SAE, EN, DIN or JIS).

Capacity and reserve

Ah and reserve capacity matter for vehicles with heavy accessory loads, sleeper cabs, boats and RVs. CCA cannot be converted into Ah.
