I'm in the Midwest, KC Missouri. Store my unit under cover but exposed to the temperature. We have some days close to zero and many more in the teens and twenties. Here is what I do. Always keep battery cells full of liquid. Battery is fully charged when I put in storage. A fully charge battery will never freeze. (at least theoretically) Remove negative cable from battery. Leave battery in unit. When I go to take it out of storage hook up negative cable. Generally only in storage 4 months or less. Has never failed me when I take it out of storage.
