I keep my trailer batteries safe over the winter by taking them South in the trailer.
My boat batteries get to stay home here in Ontario where it gets very cold. For the last 30+ years I have charged them in Nov, disconnected them and checked them in Apr. No problems.
I know one guy who had a trickle charger on his boat batteries. The power cord got disconnected and the charger became a load that ran his batteries down. Two of them split spilling the electrolyte into the bilge. Bad.
Also - the concrete myth is a left over from batteries from the 1940's 1950' or earlier. It does not apply anymore.
