2007 Yukon battery/starting issues

I have a 2007 GMC Yukon. In recent months I have had two occasions where overnight in the garage the battery went totally dead with no accessories left on. After multiple trips to the service dept nothing was ever replicated or identified to be wrong. Have not had that issue for about a month, but last week the truck would not start. All lights, stereo, heat...would work. Battery had full power. When you turned the key nothing, not even the slightest click or noise. Had it towed to the dealer, next AM they started it right up. Kept it all week and it always started, never lost bat levels... Diagnostics showed nothing. Only other odd thing i notice is that I could walk outside right now and open the door and if it is quiet you can hear noises like electronics booting up. Sounds like the CD player ejecting plus other noises. Any insight would be great!

? Dealer didn't find anything in a week?? OK - was the battery really dead the first time or more like disconnected, presets on anything lost as well?
Some things must be known good to even begin the hunt. Battery (age really matters so find out) and connections right there an historic trouble spot and both other ends of cables - bat + to starter, bat neg usually to side of engine block have found some not correct there new, bolt tight but cable wasn't!
If battery was truly dead and especially if very cold then battery itself will always be in question,
