My car won't start after its sits for a day or two. It has a brand new top of the line battery and when it's running its sounds fine. It's almost like something is on and it's pulling power from the battery but we have. Checked everything......

Just to add to this one if the battery is dieing with it off then you have a excessive parasitic draw.I would have the alternator tested it could have a bad diode trio causing a draw.Also a parasitic draw test will have to be performed. I have seen window switches killing battery's the strangest things can do it trunk lights door switches who knows.
