The bad news is that if batteries are fully discharged (ie "empty") then 
they can freeze in cold weather - the electrolyte is basically water.

The good news is as long as they are fully charged before storage, they 
won't freeze as the electrolyte is much more acidic with a low freezing 
point (like minus 20 or so). And the cold slows down the self-discharge 
rate.

So I'd run a charge cycle once or twice over the winter, similar to what 
Jack said.
