Motorcycle Battery Size Chart
When searching for a motorcycle battery, we often get asked, “Are there different size motorcycle batteries?” The answer is a definite yes, and there sure are many of them, as you can see in the charts below. We often help our customers find the correct battery using our battery finder, but there are cases where a customer has a brand not listed, or the application is custom-built.
In those cases, the easiest method to find the right size battery is to work off the existing battery part number, or we can also go by the dimensions of the battery box. Customers with custom-built motorcycles will often ask, “What size battery does my motorcycle need?”
This can be tricky to answer, as a lot depends on the engine size and starter gearing. Our general recommendation for finding the correct battery for custom applications is to go off the original battery you are trying to replace. If you don’t have a battery, you can check our battery finder for recommended battery your applications motor came from. Or you can try to fill the battery box with the largest battery it can hold.
The charts below shows you the sealed AGM motorcycle batteries available today. These batteries are used among most powersport applications, such as motorcycles, ATVs, scooters/mopeds, UTVs, snowmobiles, and personal watercraft like waverunners or jet skis. If you need help finding the correct battery, feel free to give us a call or email us via our contact form.
