Last year I was able to drive my car throughout the winter because it was in a heated garage that had a car wash inside. So I drove it 3 or 4 times a month and washed it immediately after.
This year I'm not sure what to do. First I have to check if my garage even has an outlet. If it does, any recommendations on a good battery tender? If not, what can I do? Take the battery out of the car and plug it in inside?
