This is exactly what the boat mechanic at my marina told me. he said " if they are good batteries they will just need a little charge in the Spring. If they are junk they will be dead in the Spring. Better to find out then than when you get it in the water." I have 2 batteries with a switch. When I had the boat winterized they just disconnected both batteries.
