Just wondering if any of you guys ran across this.....Sam's Club tells me there are 2 kinds of batteries for my civic(2001, EX), an R, and an RS. Anyone figure this out? How can I tell by looking at my car/VIN, or otherwise?

Thanks,
Joe

 

They're not just different grades, one with a longer warranty but higher price? If that's the case you can buy either one and it will work.

 

Thanks!
