What kind of battery did they sell you? I love my Optima Yellow Top, especially because i store the car over the winter.

 

No, they aren't. It takes a Group 35 which is readily available, it's just that nobody seems to have the GTO in their application guides.
For not much more than you paid for a not-so-great Delco battery you could have had an Optima Red Top which is far superior. Oh well.

 

Deng..iFail.:banghead:

 

The Duralast Gold from Autozone is an excellent battery and it looks great in a Yellow Jacket !!

 

Same one I've got.

 

when my battery died the only optima had side posts andmy car was at the race track so i had to get it running, so i paid 130 bucks at the stealership

 

There are no Optimas with side terminals only, you were looking at the "universal" type with both top and side posts. Although not the preferred configuration it will work with some modification (bending) to the cable terminals, and would have been a better option than the dealer battery.

 

what part number is that duralast gold? It fit in the hold down with no issues?

 

The Autozone part number is 35-DLG, it fits with no problems, here is a link with all the BCI battery sizes, it's handy to find a cross for automotive batteries.

 

My Optima yellow top has top posts...

 

....also watch that stock battery. If you are not careful it will start to crap (leak) fluid all over your engine bay. That thing sucks.

 

That's what mine did, almost immediately, acid coming out from around the positive post.

 

I've had a Sears battery in mine and when it crapped out I replaced it with a Superstart (O'Reilly brand) they aren't as easy to find as a group 24 battery but they do exist outside of the dealership.

 

the ac delco batteries i had in both my '98 silverado and my '01 both leaked acid from the positive post and destroyed the cables

you'd think i'd learn my lesson but i still haven't junked the POS in the goat. need to get off my dead ass and do it already...........

 

the OEM replacement size for the GTO is a group 85 -- its a battery thats commonly found in cars from asia and the pacific rim. its about the same size as a 35, which is very common and will work just fine.

currently my GTO has an optima redtop in it, and its junk -- isn't worth a s**t on a cold start

 

I just bought 100 D flashlight batteries grouped them together and yanked the battery terminals out of my t.v. remote and hooked right up, I think it added 20 hp too

 

But u can only use energizer batteries its the bunny that makes them work
