A lot of good points here. Just to be clear, ALL batteries will lose about 3% of charge a week just sitting on a shelf doing nothing. A long slow trickle charger works great for automotive starting batteries and sort of okay for these 12v hybrid “deep cycle/marine” batteries (sort of). A battery will sulfate if drained too low. An equalization charge after fully charging the battery may save it, but ultimately it will have a decreased life span now. If You’re plugged in all the time camping you probably won’t notice it. If you boon dock at all, the 6v deep cycles are the way to go. Still 50% state of charge is the minimum with any FLA or AGM. It will or may still go for awhile....but.
Disconnect FoR sure. And/or a tender.
