Optima Battery That Fits?
I need to replace my stock battery and would like to know the correct replacement Optima battery model number and any special installation it takes or parts. Would like a larger capacity than the stock GM battery. Thanks for the help.

Re: Optima Battery That Fits?
the only thing that is a direct fit for the H2 is a group 79 battery ,an optima will fit but not as well as a group 79 . just get a good 850 to 900 cca group 79.

Re: Optima Battery That Fits?
I just went to Advanced Auto Parts store. They looked it up in a Optima booklet. They installed it for free. Their price was very good. It fit fine, no problem at all. They used existing clamp. It has worked great.
No, I do not work for Advanced. Come to think about it, I do not work at all anymore!

the optima fits with the adaptor on the base of the battery,but the group 79 fits better IMHO,and I have used both.

So are we talking about fit or performance?
I have an Optima in my Firebird and I love that is always ready to go when I need it and we getting one after the new year to replace the one in the HUMMER since we do not drive both of them everyday. ~Richard

Re: Optima Battery That Fits?
you can jam 2 regular size yellowtops sideways there and link'em together...more capacity than the biggest single battery.
