I leave my batteries in while stored over the winter and I have 6 6V batteries as part of my system with solar (hence my back says no way to lifting them in and out each season). My method is to make sure it is fully charged when I put it in storage with everything off and battery disconnect pulled as well as I have a battery switch in-line. I then stop by about every 4 weeks or so to check their status and once they are down ~ 10% in charge, I hook it up to my portable generator for a hour or two to top them back off using my inverter/charger and I am good to go again (and I get a couple hours of undisturbed time to catch up on reading while its charging). In general, doing it in this manner vs a trickle charger is considered better for the batteries by some overall as it isn't having the constant heat of a charger ongoing.
