We winterize around 200 boats here in Canada and never take the batteries out just disconnect after we have finished.

I pull all of my batteries from my boats (4) and put them into my solar grid system and maintain the 13.2v-13.8v float charge that is recommended. (from the charge controller) They also see some cycling when out in my building.

And you are correct, storing on a concrete floor does not hurt a modern sealed battery that is in, otherwise, good condition.

This would be the time to 'winterize' which means getting a windbreaker out of the closet.

I don't like keeping them on concrete for temperature reasons. Keeping them elevated keeps the temperature more uniform from bottom to top. I don't have radiant floor heating, but that would be a different element.

The last few years, I have just left them in the boat, and plugged the boat in for about a week a month to keep them topped off.

I know I am bringing up an old post, but I've pulled my batteries from my Donzi and am storing them inside for the winter.

Which charger would you recommend? ..Pulled them around end of October and they have been sitting in my guest bedroom since. Interstate Deep Cycle Marine/RV. I know I need to get something hooked up to them to maintain until spring.

Thanks

I have one of these mounted in my Garage. Charges the boat batteries and my summer car battery. Easy, plug em in and forget it.

Have used this model for years with no problems. We use the larger 48vdc model for batts at work with same success.

I live in Michigan and bring both boat batteries, 3 Mustang batteries and the lawn tractor battery into the basement every winter. I don't know if it helps but I usually do get a long life out of batteries. I also keep them elevated and off the cold floor and put a slow charge into them about twice over the winter. lol, just realized that I answered this thread over a year ago!

hello,,yes i am also in the lovely state of michigan, for years i use to always bring batteries home , put in basement on a peice of wood, then trickle charger them. but now keep current boat in my heated garaqge year round, so just leave batteries in boat and trickle charge them every 3-4 weeks.
if your boat is sitting in a boat yard, i think i would still bring them home, as you couldnt charge them in a yard.
