I just bought a used 2000 Dodge Neon and have to replace the battery. How do I go about finding out what size battery I need? It doesn't show up in the manual. Thanks.

 

Go to any parts store and they can look it up and tell you. You need a battery core anyway. Most part stores will even put it in for you.

They use Group Numbers to tell you what battery size to use. Your battery may have a group number printed on the top, and if they do, replace it with a similar group number battery.
