I think the OP is making way too big of a thing out of a simple battery replacement.
1. Remove the battery
2. Go to your favorite auto parts store ... They will sell you the correct battery for your car.
3. Install the battery
4. Index the windows
Don't try to overthink all this ...
As I said above, yes, you are correct... i overthink lots of stuff... Which of course tends to make things harder and more stressful than they should be. Yep, that is unfortunately how not my car but how I AM wired. been that way all my 64 years. bob
thanks for the help... Now trying to find a good battery with the right dimensions. Some "replacements" appear to be larger and I would like to stay away from "larger" so I can truly put the new one in in 10 mninutes like the guy in the YouTube video did...
thanks... bob
FWIW, I recently replaced my AC Delco OEM battery with a Optima red top, and it was a perfect fit. Same dimensions too.

The overthinking is OK...it's a hallmark of the Corvette Forum. For proof just start a thread on battery tenders, motor oil or any number of other subjects....I'll bet ExxonMobil doesn't overthink their oil as much as we do here on the forum...LOL

Good point.. As a chronic "over thinker" I do feel somewhat of a kindred spirit here on the forum...
thanks for the input on buying a new battery... Yes, I will be buying one in the next couple days. Long story short I've been to hell and back in the past couple hours with more weird flashing dash lights, more strange DIC messages, more strange sounds coming from under the hood as some relays were clicking in some strange ways, apparently due to low voltage. Got locked in the car but knew of course about the manual handles. Then got locked OUT of the car but had already revisited how to use the mechanical key to open the trunk and then the pull handle to open the door. However, I would pull the handle, pop the door, but then walk around to it and each time it had not clear the lock or something. I would hard close the door, pop it again from the trunk, walk around to the door and same story, popped slightly open but not "openable"... Panic started to set in but I got my wife to come to the door. I hard closed it again and again popped it from the trunk but this time with her tugging on the door and it came right open. Whew... Tried three different times to jump start it. First time showed some promise but it just wouldn't fully pull in the solenoid and start. Second try seemed even better until suddenly all ceased to work, only to find that the negative connection on the engine bolt (gosh, what a tough place to have you hook up ground) had popped off. So three times is a charm, right??? Well, yes, it was... After the solenoid popping a number of times, it finally engaged and started right up. Must be a really bad cell or something... Took it out and drove it at good speed for 20 minutes or so. Brought it back, shut it off, and least one time (all I've tried) it started again. But at least now I know I can jump start it...
I parked it with the windows down. Also thought about lowering the covertible top but decided to leave that up. Gotta do something else tomorrow but Tuesday I will be either going to Napa Auto Parts, the only place we have here in our small town, or going to the nearby chevy dealer for a new battery there... I will have to read about some of these newer battery technologies, at least new to me.
Just went out after an hour and started it again. It cranked slow once and then started. Likely won't make it through the night without another jump.
Anyway, thanks for your input... bob
Where are you at in NorCal? My '09s battery died the other day and I was able to buy one from Batteries+Bulbs in Roseville, CA. The kid at the store installed it for me in a couple of minutes and it only cost $129. The label says "Duracell", the CCA is 590 IIRC and it has a 36 month warranty. You might give that a shot before you spend close to $200 on a Delco battery with lower CCA rating. Batteries is batteries. It's about CCA/$.

I also replaced the rinky dink battery cable ends on mine with some of the gold ones from Advance. They are not the cheapest but are if not the best close to the best.
Mainly because of local availability, I am deciding to stay with AC Delco. My local Chevy dealer has TWO that they say are meant for my Corvette, a
85PS and,
90PS
They have both. The 85PS appears to be the direct replacement for my OEM batter, an 85H7YR.
Does anyone know whether the 90PS is better than the 85PS. Even on the ACDelco website, I can't find any reference to those specific part numbers. I even tried their online chat and no one would ever answer..
Gonna buy one or the other. Just want to know if anyone knows how or why one is better than the other??

One isn't better than the other. The difference is size. You want the 85. The 90 is for dry sump with the battery in the back cubby.

Just size/shape. My '07 Vert had a group 90 from the factory. After six years I replaced it even though it was working fine...just did not want to get caught in the middle of nowhere since that is where I live. I did a new one from Walmart as there are lots of them and if I ever needed a replacement, I could get it at 9:00 at night in many locations. Been doing great for three years now. It's very likely that no matter where you buy it or what name is on it, you will get a battery made by Johnson Controls so don't sweat it too much.
Hi folks. Did the battery swap today. As many of you suggested, it was easy. Especially since I found one great youtube video showing exactly how to turn the battery to get it out and put it back in. Better to watch that and follow the lead rather than doing my own trial and error on how best to turn the battery. Did the out and back in in less than fifteen minutes...
Started the car right up but a few seconds later it died. Never has it done that before but it wasn't electrical. My guess is it perhaps had sucked in some water when I had tried to start it after it was pretty much dead a couple days earlier... Anyway, started again and ran fine.
Only issues were the windows and convertible top would not work until I re-indexed the windows. Expected that and fixed that easily. But what I didn't expect was all four TPMS sensors read precisely 0. And they stayed at 0 after multiple starts even though the TPMS caution light was not on and no messages showed up on the DIC. I didn't find anything in the manual about that. I was about to go out and drive the car to see if that would bring them to life when I decided to pump maybe a pound of air into one of the tires, mainly so I could watch the gauge on my little battery operated pump. Mainly I wanted to be sure there was plenty of air in each Run Flat (even though I KNEW they were inflated). When I added at most one pound of air, suddenly that sensor worked fine again. Same with each tire after. Just hit each one with a tiny bit of air and they came to life one at a time... Interesting...
Anyway, thanks to all for the many pieces of very helpful advice. My Corvette is back and running again. BTW, replaced the old one with another like ACDelco battery. Mainly because I could get it quickly. We retired to a small town outside the SF Bay Area that has limited shopping options. Old battery was an 85H7YR. The new one is an 85PS (Pro Series). Other than model number, they have the same specs and look essentially identical.
After reading thru this thread, thought I'd go put a meter on my 12 GS OEM battery and see what she reads...... 12.4 volts sitting quietly in the garage. Any thoughts on how that stacks up for a 5yr old? Car was last run two days ago....
Designer Imagines A Corvette That Looks More Like a Corvette Than the Corvette
Slideshow: A Jaguar designer's personal project imagines what a modern front-engined Corvette might look like if Chevrolet revisited the golden age of the Stingray.
