What should you check before buying a car battery?
The right battery is the one that meets your vehicle’s requirements and fits the tray and cables. Check these details in order so you can rule out a poor fit before comparing extras.
Which group size does your car need?
Use the group size specified for your vehicle, then compare the battery’s dimensions and terminal positions. Our guide to car battery sizes explains what the group label tells you.
Does the battery type match?
Check whether your vehicle calls for AGM or another battery type. If you’re unsure whether a switch is suitable, read AGM vs lead-acid car batteries and consult the vehicle manufacturer’s guidance.
Is the CCA rating high enough?
The battery must meet the minimum CCA required for your vehicle. Use the owner’s manual or manufacturer specifications, then read how many cold cranking amps you need for more context.
Do the terminals and case line up?
Confirm the case dimensions, post type and positive and negative locations. A mismatch can make installation difficult even when the group number looks right.
Which car battery should you choose?
Choose the ACDelco Gold 48AGM if your vehicle specifies Group 48/H6 and its fit details match. For Group 94R/H7, compare the ACDelco, Interstate, Mighty Max and Autocessking options by their listed ratings and warranty terms.
For a different group size, use the vehicle’s requirements to narrow the choices first. Then review our car battery brands guide and replacement checklist before ordering.
A correct fit and battery type matter more than a higher score. Check your manual and current battery details before you buy.

Frequently asked questions
How do I choose the best car battery?
Start with your vehicle’s required group size, battery type, minimum cold cranking amps and terminal layout. Then compare warranty terms and features among batteries that meet those requirements.
A higher score in this guide does not make a battery suitable for every vehicle.
Can I use a different group size car battery?
Use the group size specified for your vehicle unless its manufacturer or a qualified battery professional confirms an alternative. Group size affects dimensions and terminal placement, so a battery that looks close may still fail to fit or connect safely.
See our car battery group size guide for more on these labels.
Should I replace an AGM battery with another AGM battery?
If your vehicle came with an AGM battery, follow its manufacturer’s replacement guidance. Some vehicle charging systems and start-stop features call for a specific battery type, so confirm the requirement before switching.
Our guide to AGM and lead-acid car batteries explains the main differences.
How many cold cranking amps does my car need?
Use the minimum CCA in your owner’s manual or vehicle specifications, and don’t choose a battery below that requirement. The right amount depends on the vehicle and its operating conditions.
Our guide to choosing cold cranking amps covers what to check.
How can I tell if a car battery fits?
Confirm the group size, case dimensions, terminal positions and battery type against your vehicle’s requirements. Check the year, trim and engine, since fit can vary within one model name.
For a replacement checklist, read what to know before buying a car battery.
