are all delco battery bad. my started to leak from pos post
9 out 10 battery go bad . There should be a re call on all batterys in corvette :mad

 

No. My battery good. I did have bad battery. Now I have good battery. :D

 

Get the new ACDelco AGM battery. 78P7YR. Part# 19002255.

 

Same one I replaced my original leaker with. No problems. :yesnod:

 

myron-I had mine replaced under warranty 2 1/2 years into ownership with no leakage before of after replacement. However, I couldn't stand not having the AGM(absorbant glass mat) battery in my car so I coughed up the $100 or so to get peace of mind about six months ago. Leakage down onto the computor and wiring harness is not fun to deal with as you can imagine. :smash: :smash:

 

Changed mine out with an Optima Red Top. Didn't want to risk the leakage issue plus with the Oprima my lights to sporadically dim at night.

 

I just changed my battery to the Optima 78/34 Group Red Top. (perfect fit)
If you see leaking around your Pos post - you gotta tend to it quick!
There are electronic modules under the batt tray that will get ruined.
BIG $$$$ to repair.
Also, my '98 starts a helluva lot better than before. :thumbs:

 

I read a tip on the forum dated 10-8-2002 that mentions the 78P-7YR, but then on the C5 Registry I read this:

More Power To You!!!
Thanks goodness! GM is listening after paying a bunch of warranty claims on their AGM battery!

It is well known that the AGM battery 9" size (catalog #2277) installed as OEM equipment for the last several years in C5 Corvettes has been, in our opinion, a discharging malfunction. It’s known for leaking from the terminal bolt-in points and if you don’t drive your C5 daily, it loses power quickly. The final insult is if you ever have to have it replaced under warranty the dealer never has one in stock so they must always "overnight" one as a replacement part from Delco, so that you lose the use of your C5 (the Corvette of your dreams!) for another day!

Now, for the good news! # 78-H6YR has arrived and is the warranty replacement for the AGM! Who is the new power source on the block? It is a brand new 675 cold cranking amps (compared to the AGMs 500 cold cranking amps) 10" monster (vs. 9" AGM) with a 110 minute reserve (AGM only gave us an 80 minute reserve). This side terminal black beauty with carry handle has arrived! And not a minute too soon!


So, when your AGM fails (and we know it will!) start memorizing the number 78-H6YR.

You and your dealer will be glad you did!"

So which is it 78P-7YR or 78-H6YR?

And also can I just go into my dealer and say "My battery hasn't leaked yet and screwed up my computer, but we both that it will...can you just replace it now under warranty?" Will they even do this?
