I've have 2010 Ford Edge ,same problem since new ,about every 6 months ..sometimes 8 months ..just dead ...clicking ...nothing left on ..I've read a lot on this topic , 3rd battery ..this battery is almost a year old ,it's a 36 month ford battery ...jump it and its fine ...test fine ,Alt test fine..thinking it's the CD player stuck trying to eject once in awhile ,or we had a phone charger plugged in , I'm thinking maybe computer can not go into to sleep mode ....sometimes ...charger has been plugged in for months ,left plugged in ,not charging anything but charger does have small Led built in ..I know the led won't drain it ,but might cause the computer not to sleep..I have no remote start or par roof ...no after market anything ...
