I remember reading about batteries freezing and should be removed from boats in very cold weather.
Does anyone actually do that?

Never heard that Brett! I don't move mine until needed to be replaced. Mine are on a on board charger and I think the heat from that keeps the water from freezing. I use to have a old aluminum boat I kept outside in the weather and never had a problem with the battery in it. I do know if it matters! I'm sure I'm about to learn something though :)
Up north they do that when they winterize their boats and put them in storage till spring .

Naw, car batteries don't freeze. Same for our big boat batteries. I lived at the IL/WI border my whole life, froze my you know what off all those years till I wised up and moved to FL.
Sure, some might take them out to keep a charge on them, so they don't die over the winter (cause 3-4 months of cold with no use/charge will certainly do that).
The amount of charge in lead acid batteries is a function of the specific gravity of the fluid in the battery. Pulling this out of the cobwebs in back of my mind but I believe the specific gravity of water is 1. When fully charged the SG of a battery is around 1.125. The more fully discharged a battery becomes the more like water the solution becomes. So a "dead" battery could freeze and burst just like a hose or spigot left unprotected.
Because we don't get a lot of " pipe busting" cold in SC batteries don't often freeze and burst.
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.
More than you wanted to know, right? Engineer's curse.
Thanks SeaRay!
I’m always learning something new.

Just to add to my story, all the time I lived up there, I never once heard of someone's battery freezing and bursting, and I heard many go dead on folks. I'm not trying to discredit anyone, I'm sure SeaRay is 100% right, I'm sure they'd eventually burst, but IMHO extremely rare indeed. I have seen "so to speak" koozies on batteries! Wrapped in insulation, never understood that, unless it was to protect it from the heat.
Now off to SC for a writers camp where it's supposed to be freezing. First time I've put pants on in many months, yuck. ttyl all
I too have never seen a battery burst from freezing. I was speaking in theory as to the possibility. I would venture to say that if you were to place a completely dead battery outside in the coldest SC weather and checked the water in the battery it probably would be at least partially frozen.
Would it freeze solid enough to burst the battery. Probably
not.
Slab you've managed to pick the nastiest weather we've had in months to come visit our great state! Hope your visit is a good one.
well I've had them go bad, as well as freeze/crack case
so they go in the basement up here...fwiw
JUST TELL ME WHAT TO DO!![emoji1] [emoji1]Quote:
