I’m wondering about the minimum amount you need to run your car to maintain the battery. I live North of Boston where the normal winter temps are in the 20 degree range but we get really cold weather too. I own a car out of necessity but I hate to drive so I can go two weeks without driving (I use a lot of mass transit).
This isn’t Minnesota cold so that’s a whole different topic.
I have AAA so I can get a jump start if needed but I like to count on the car when I need it.
Also, is there a problem with just starting the car and letting it run for a while vs. actually driving it around?
