How to Determine Car Battery Group Size
- The first place you can look to find the proper battery group size for your vehicle is the Owner’s Manual. If the company did it right, the manufacturer specs should be easy to locate.
- Look directly on the battery you’re replacing.
- The next simplest way is to ask an expert.
How do I know when my car needs a new battery?

- An old battery.
Can I put a smaller battery in my car?
Yes, adding more amps or reserve capacity for your car battery won’t hurt in any way. It will add more cranking power to your engine provided that you will still get the size that will fit your car. Amps or reserve capacity is not an issue in a car battery.

Cold Cranking Amps (CCA)
