I live in MN and have seen batteries freeze. Those batteries were not fully charged. Cold storage will actually slow down the chemical reaction inside a battery and will help hold the charge if left outside. However, the best longevity is keeping a constant float charge on the battery. The float charge is necessary so the battery plates don't start to build sulfate crystals. When you don't float the battery and have intermittent charging, some of those sulphates will detach from the plates and after mixing with the electrolyte, sink to the bottom of the battery case. Both of these result in loss of capacity.
Users that intermittently charge batteries and keep them in a cool area will see more longevity than leaving the battery unattended for a storage duration. Those that keep the correct float charge on them will have the most longevity. Or, you can be like my neighbor, the Son of the shampoo tycoon, just keep them in the boat and replace every year. About every few years he has a garage sale and I buy up his marine batteries. My battery backup sump pump is still powered by one of these batteries. I think it is on year 11. It has a small transformer for float charge.
