From what you guys say, it appears it just didn't hold a charge / didn't have the capacity to charge up any more. The fact that it would not even run the fan / radio tells me that it was empty.

An interesting tidbit is that I parked the SUV at a 30 degree incline for 3 nights now in my driveway. Something I never do, as the driveway is so steep, but street parking was blocked due to paving work. I think it is possible that either the fluid not fully covering the plates sent it over the edge, or that the truck has something turn on at this angle (an interior light?) that drained it. I did not park it this way tonight to ensure there is nothing funny going on with a drain at that angle.

The battery was dated 07/10 and a "never start" product, so I brought it back to WalMart. Since it was late, nobody asked to test it first (which they usually do) they exchanged it for a new one at no cost (3 year full replacement). It is back in the SUV and I will report back how it goes.

Thanks for your input!
