I keep mine on charge and don't worry about them.
Mr Google says : “A 100 percent fully charged battery will not freeze until approximately minus 76 degrees Fahrenheit. A fully discharged battery can freeze at or around 32 degrees”

"Leaving a battery on a smart charger full time is the best insurance against freezing plus it's best to keep fully charged anyway to avoid sulfation of cells."
That wasn't clear enough for you?

Up north here in Michigan I pull my batteries and put them in the basement fully charged when the water turns solid. I figure for the cost of those things it's worth my time to do that for the 3 months or so I can't use the boat. Can't hurt and may prolong the life of them.

I only carry my power drill batts, pole saw batt, and my lawn mower batt into the house after fulling charging and washing it up. Don't know for sure if it helps but I get ALOT more years out of my mower battery since I started doing this 10 years ago. I occasionally hook my on-board charger to the boat batts during an extended stay in the boat shed...be it winter or summer.
Lowrance is all upset about me not trying their new stuff.
They claim it "in the sponsorship contract " , blah, blah, blah......
Well my wife has a contract too.
