I could get really kinky with that.

But I won't.

Give this some thought, I have a boat that has four batteries. For at least ten years I have charged the batteries (November) and then stored the boat at the Marina. NE Ohio usually sees a few sub zero days each winter. I have never had a frozen battery on a charged (good) battery. Every now and then I know a battery is going bad and it won't hold a charge, but, I get lazy and leave it in, it will freeze.

I also sell high reliability lead acid batteries for industry. High temps are far worst then cool temps. There is actually a life/derating chart for temps above 75 degrees. Another issue is discharging the battery lower than 85% of nominal voltage. I also sell battery monitor systems that project battery life, the algorithm includes time over 75 degrees, number of discharges and level of the discharge.
