I regularly leave my car at the Phoenix airport for four day stretches while away on business. I turn remote access off to reduce vampire drain, but I average about 6-7 Rated miles loss per day. The least loss I've seen is about 4 Rated miles per day. Vampire loss is the worst when the car is parked on the parking lot roof in the sun when the ambient temperature is over 90. The battery cooling system kicks in. At times like that, I've seen 35 Rated mile loss over four long days.
