I'm not sure where you are located. How cold are your winters The colder the winter the less often you need to recharge the batteries over winter (this is assuming you do no ever use the batteries when they are cold). This also assumes you start the storage period with the batteries fully charged. If you have cold winters, or even coolish winters there is no good reason to take the batteries out of the boat.
Self discharge slows as the temperature drops. Does that help? Ken H.

I have been removing my 3 flooded batteries and storing them in my garage, giving them a monthly charge “top up.” Would much rather not carry them down and then back up the ladder comes spring. My boat is 1 hour away in the winter so do not get there that often to give them a regular charge. > > > > Do you charge them on regular visits to the boat?
