I wanted to let you know that I did receive your question and I am working on getting the answer from the manufacturer. I apologize for the delay. As soon as I get the answer, I will update you and the product as well. Thank you for your patience.

The systems should be good to stay on the batteries during the winter. The only thing you will have to worry about is making sure no water is left in the male coupler. You can do this by keeping the coupler elevated on the battery, this will allow water to naturally drain into the system as it lowers.
