....I need to buy a new one and dont know what type of battery it is, Looks quite different than the one in my camry.

It is a 91 series.

Interstate Batteries part number is MTP-91. Oh, they aren't cheap....

I went with a Diehard battery this spring. It was $109 at Sears.

Group 48 is the one you want:

Also has a 3yr replacement warranty.

yea, purchased one yesterday and it cost me 110. The interstate one is not as wide as the OE one so I had to bend the metal to stop it from shifting.

[I have an outie]

what is a 91 series battery and why is it different?

[no1hustller]

Most battery manufactures use common sizes. 91 is just the size for our cars.

I don't remember my interstate being smaller than the original, however.
