Nah. Charge/discharge cycles is what hurts a lead-acid battery, not temperature. Especially discharge below 80%. True, extended cranking can discharge it below that, but making it work a little harder for the brief few seconds it takes to start a modern automobile won't hurt it. And although output is temperature dependent, longevity isn't. If it doesn't freeze, and it won't if it's on a float charger, the battery won't be damaged by the cold alone. Especially in storage, which was what we were talking about anyway.
