By the way, I just got my car out of storage today, this is the first year I have ever done an unheated storage. Here's my trick. When I store my cars I remove the battery altogether and store it on a wood shelf in my heated basement. It sits from mid November until mid April. When it's time to get the car I drop it back in and it fires up every time. NEVER in 15 years have I had a dead battery after doing this. The battery literally sits for five months and still holds it's charge.
