Something is drawing power, dome light, glove box light, trunk light, hood light, radio, something plugged into power receptacle, etc. In very rare instances a stuck power door lock or power window relay can cause this.

check battery cable connection to see if loose.could also be a drain on battery,check to be sure all accessories were turned off overnight.
