Location: Musky Tackle Online, MN | I live in northern MN where there are many nights of 20 below or colder every winter. My boat stays in an uninsulated garage with holes in the wall that help bring in even more cold air. I've never taken the batteries out during the winter. I'll sometimes put the charger on them once or twice during the winter. But it never takes more than a few minutes before the batteries show a full charge, so even that hasn't been necessary. I just had to get a new starting battery after 9 years. I would say the cold winters with little charging served that battery well.
