I don't know if any of you have had to replace your battery yet, but strangely, Wal-Mart, Checker auto, and Autozone have no replacement battery part number listed in their system. What's up with that? It's just a battery. Guess I will be going to the stealership.

You can order a top post battery from Optima, Odyssey, or go with a dry lead race battery in which case it will come with its own bracket. If you can't find one at a car parts store, try marine batteries. They are suited just fine for automotive use and usually have a longer warranty.

You can go to www.acdelco.com and search for a local battery distributor in your zip to locate the 85H7YR,,,, but it may have to be ordered. In checking Sears to see if they had a Diehard that fit,,, it was also a no go.

Another step is to measure yours and match the CCA rating with one that has the same dimensions with either top posts or dual post terminal connections.

Don't forget..... The battery falls under the 3/36 warranty. Just in case your warranty hasn't expired.

There has to be a cross-reference list from Delco.

Factories never put the best in a car.... Delco's best ranks at the top with other batteries. I swear by Delco Batteries. (the top of the line ones)

I went with the Optima Yellow top. you just need to bend one of the terminals to fit.
Do you have any pictures of what you had to bend? I'd rather not bend things if I don't have to but I can't find a battery anywhere aside from the dealer. Those Optima's were 170.00 though... Any idea how many CCA those OEM batteries are?

I have a 2005 GTO & faced the same problem & there is also no listing for the 2005 corvette either which I thought would be the same. Maybe this will help some of you, Here's what I did:

Called my local stealership & found they want $150 for the stock AC Delco battery that lasted only 3 years. Yea, right....Unlikely. So Plan B:

Measured my stock battery: 8 3/4" x 6 1/2" x 8". CCA (Cold Cranking Amps)= 600.

Keep in mind, you can go above the stock CCA of 600 & it does not matter, but you can't go below 600.

I then went back to Wal Mart with a tape measure & found that the MAXX-35N (640 CCA, $76) was the closest fit (about an inch longer) which is OK because the GTO has plenty of room in the battery compartment. Installed battery in 10 minutes, fired it up & hit the road. Done.

If you don't like Wal Mart batteries you can go to Interstate & use the following:
MTP-86 (CCA 640) $117.00 in Northwest NJ. I called Interstate direct, they have a distribution center a mile from my home & the guy worked with me to find this battery however it measures 9 1/16" x 8" x 6 7/8" which is a bit larger than the stock & Wal Mart batteries but it should still fit. I would have purchased the Interstate simply for the 5-year warranty & better price than the dealership but money is a huge consideration for me at the time of purchase.

So here is two (2) options for you if you don't want to spend over $200 for the Optima racing battery:

Wal Mart MAXX-35N -----> $76.00 w/ 3-year warranty
Interstate Batteries: MTP-86 ------->$117.00 w/ 5-year warranty

I must say the Wal Mart battery is working superb & with the added 40 CCA cranks SO MUCH better than the stock battery which was obviously too weak for the LS2 motor.

Hope this helps! Go GTO!

You sure the dealer didn't quote you that price on Delco's Professional Battery? At last I was quoted a price it was like 120.00.
