If you drive cars regularly then just disconnect it. Is garage insulated? If it is, it should be fine. Sometime ago I had often trips to Europe month or longer and I would leave vehicle in Alabama outside during winter for that period. Now, winter in AL is obviously much, much milder, but temperature during night drops below freezing for most January. I never had an issue with any vehicle except Mazda Millenia. I always had to jump start that one.
