Parked Battery Life - How long does a charge last?
How long will the battery charge last with the car sitting parked? Going out of town for three weeks and wonder if I need to put a battery tender on it or not. My old E30 BMW would usually only last about two weeks or so. West coast weather so 40s at night, low 50s during the day.

It depends a lot on the age/# of cycles of the battery. At a minimum I would expect 2 weeks with the car locked in a climate-controlled environment.
