Okay, for anyone who's interested...
The Delco 79-6YR has screw-type terminals, not posts. The positive & negative cables on the 2K series Deville have 1/4 inch bolts that are accepted by this type of terminal. They are charged to 14.5 volts at the factory and carry a 6 year/75K mile warranty. My Caddy dealer had one for $139.00. Other options are the Delphi brand available at Autozone for $118.00, or you can fit an Optima in there too.
In my case, I had some fluid that had leaked through the positive terminal, resulting in it's eventual demise this morning. Eventually the threaded area surrounding the terminal became weak enough, until the cable fell off. I suspect the high charge rate in the Deville may have contributed to this, although it could just be the heat here...there wasn't a lot of acid on the floorpan, so it probably happened recently, and this has been a hot summer here.
I'm glad it was only the battery...I was able to switch it out in the parking lot, and it saved me a tow to the dealer and labor charges. Hope this helps someone in the future.
