Just my luck , no start Dakota outta da blue

Bad battery of all things, which didn't make any sense what so ever to me. It's like it dropped dead in a few hours. The ignition key works perfectly. It MUST be in the off position to be taken out. Unlike my wife's Durango which can be taken out in any position.
The radio turns off with the ignition and was turned off before I exited the truck. Interior lights were off, bed light was off, cables in excellent shape, total mystery to me.

It has not skipped a beat prior or since. Excellent and perfect operation before and since. Excellent truck.
