Default battery

I have a 2001, my battery quit last month. If you have the original one? I'd change it if I were you.
to save all my settings, I clipped another battery on to the alternator battery post, and the alternator itself, changed the battery, and all is good.

The AC-Delco battery you describe is an Absorbent Glass Mat (AGM) battery (not a gel cell battery) and you should find "AGM" printed on the battery's label. GM never installed a gel cell battery in the C5 at the factory to my knowledge. GM started installing the AGM batteries in the C5s at the factory during the 2001 model year. GM has discontinued the AGM batteries and went back to a top post lead acid battery for the 2004 model year. My understanding that the reason for this was due to a number of premature failures they were experiencing with the AGM batteries. Also see the following C5 Tech Tip:

1997 - early 2001 Battery Acid Leakage Issue

The Optima Red Top and Yellow Top batteries and the Exide Select Orbital series of batteries you often read about here are also AGM batteries and not gel cell batteries. People often use the terms "gel cell" and "AGM" interchangeably; however, there is a difference:

"All you ever wanted to know about AGM and Gel Cell batteries"
