From Trojan:
The freezing temperature of the electrolyte in a fully charged battery is -92.0oF. At a 40% state of charge, electrolyte will freeze if the temperature reaches approximately 16.0oF.

When I had to store the 5th wheel off site I removed the batteries and stored them in the garage. That was a hassle so the last 2 winters I left them in the trailer after they were fully charged. I checked them every month and found that they were fine for the 4 months stored. So now that is my plan- leave them in even in our cold Colorado winters. Batteries are now 6 years old.
We have power where I store my FW. I just plug in BUT I also use a lamp timer so the charger is only active about 5 or 6 hours a day. Works for me.

I disconnect my fiver from shore power, plug in my https://no.co/products/charging/genius turn off my disconnect switch, hook up to BOTH batteries and wait till spring...
I'm not in a cold area but I would Fully charge the battery. Disconnect the negative cable and ignore it until spring. Cold will affect thins like increasing charging times
From the Interstate Batteries website FAQ.
What causes my car battery to freeze:
NOTES: Batteries stored in a discharged state are susceptible to freezing in cold weather and sulfation. A fully charged battery will not freeze unless the temperature reaches approximately 75° F (24° C) below zero. But if discharged, it can freeze at 15° F (-9° C).
some one dug up a old post, after 11 years, I am sure he figured out what to do 😂
Yeah apparently I need to do a better job of checking the OP date. It's not the first one I answered that was old.
