How to verify the correct battery for your car
Before buying, confirm the exact group size and specifications by one of these methods:
- Read the label on your current battery, which lists the group size (e.g., 51R) and CCA (cold-cranking amps).

- Ask a parts specialist and provide your VIN for precise recommendations, since market variations can occur.
With the correct information confirmed, you can select a replacement battery that fits and performs to spec in your vehicle.
