As many of you know, my 2004 Z had its original battery for almost nine years (it would be 9 on Feb 1st). Since I had such good luck with the original AC Delco, I went with the same.
Thank goodness I was able to find how to replace it on this site:

How did you know it was time? Mine quit on my C5 at about 4 years at the service station when it was in for an oil change so I was lucky I didn't get stranded somewhere.
I find it interesting that you all went with AC Delco replacements with the known issue of battery acid possibly leaking on the electronics below it. Did they move the battery to the back in '04? I thought it was '05, not 100% sure.
I'm a big fan of AC Delco but after reading horror stories of guys having to replace $1000s in electrical components after a battery leak, the visual gave me no choice but to go with an Optima Red Top.
Oh, and 9 years for a battery, outstanding! Definitely worthy of another AC Delco.

Still in front for 04. Only change was from side terminals to top terminals. Never had any problems with the AC Delco replacements.

I have to credit the battery tender for helping on this one. I always hooked it up when I was not going to be driving it for more than a couple of days.
What tipped me off that it was dead? The "green eye" was gone.

What is it about the 2004? I have a 2004 CE (about 40,000 miles) and it still has the original battery, yes it is on a Battery Tender frequently - yet my 2001 Z06 with 64,000 miles also frequently on a Battery Tender is on it 3rd or 4th Battery? (When I replaced the battery I replaced it with a Die-Hard. The Z has front mount posts where the CE has top mounted posts). Any comments??
After GM replaced my original battery (Dead as a wet noodle) with a new AC Delco .... I realized (from researching here on the forum) I'd better get a battery tender of some sort.
Once using the Tender, this replacement battery is now 8 years old.
This spring I'll probably be replacing it with a new Delco Pro 7 year battery.

Different batch of batteries? Maybe the earlier years had a bad run of batteries (which would explain the leaking issues). They changed battery styles in 2004 to the top mounted type.

After reading here.. about all the Brand O Red or ..whatever color top Jelly battery problems ... I anted up for the best AC Delco (little over a 100 clams) for the 50 month direct replacement (84 month total I think .. I am on my 3rd free replacement ...they keep replacing them. I think this This is a sealed glass mat type battery and if it is approved by GM it should be covered in an acid explosion.
I think winter stored cars have more battery problems than the year round or daily driven vetts and this has been true only since the 50's. Some lucky ducks get 4-6-8 or more years...tho personally I feel battery blessed when I get past 3 years

Re: I finally had to replace my battery
My original AGM battery still powers my trolling motor. I took it out of the car around 2004 because it kept swelling up like a football. It has lived on the dock on a Battery Tender ever since.

Hook up a trickle charger on your battery when not in use.
I Zip tied mine to the battery & keep the hood popped but not fully opened as to not forget that it is hooked up.
Your battery will last three times longer with a trickle charger.
