So I was out of the country on business travel,for the last 5 weeks and forgot to put my C5 on the battery tender before I left. Of course on returning the battery is dead and will not take a charge....looking at the battery I’m wondering if it this the original, see pic below, is this the original battery....
I think that if the battery had been replaced(either under warranty or bought at a dealership) it would be an AC Delco "Professional" battery. ACD makes two battery versions for cars; a Professional battery sold at dealers or some independent repair shops, and an "Advantage" battery that can be found at many of the chain auto parts stores.
You should check the battery voltage at the terminals with the positive cable disconnected. If voltage is 12.3 or less after being on a charger could indicate that the battery is bad. You should take the battery to a shop and have them test for a bad cell. I would suggest buying another AC Delco Professional battery or even an Interstate MTP (Mega-tron Plus) in the correct group size. I replaced the old AC Delco in y '02 C5 and it lasted just over 10 years before it died. Went out and bought another one!
Your battery should have a date code molded in the top of the battery. That code will determine the age of the battery/
Thanks guys, been doing some more reading and now I’m wondering if the connections were just loose, used a small box wrench to remove them and they were very loose, didn’t really need any pressure at all to loosen them.

will also check the voltage.
Clean the terminals before you put the cables back on.
I don't doubt it one bit. In fact, I did the same thing with the original battery in my 2004 convertible. I ordered that car in July of 2003, took delivery of it November 14, 2003. I replaced the original AC Delco battery on March 20, 2014. Now, that adds up to 10 years, 4 months and 6 days. But I will add two factors in here. The car always had a Deltran Battery Tender on it since day one and at the time of replacement, the car only had 9569 miles.
I just checked all of this in the log book I have kept on my car since new.

Great job, c4cruiser! I believe you.
I was talking to the OP, not C4cruiser. I doubted if his battery was the original. I have had batteries last ten years.
Some battery chargers require a battery to have SOME voltage before they recognize they are attached to a battery that needs charged. The way to defeat this feature is to attach the battery from your vette to another vehicle with jumper cables and let it put some charge on the dead battery. Usually above 4 volts most chargers will start to work. However, this is more of an issue with AGM batteries and it looks like yours may be a wet cell. Give it a shot if you aren't going to replace it, but I agree with ya 12 years is damn near double the life of most batteries.

Thanks, the battery is almost 13 years old, I’m just replacing it at this point.....
