Well there is two ways to go about this baby your batteries or use them. There is so many things to do to make your battery live the perfect life. For example you should only recharge at 40% battery life not 60%. That being said.
You can just leave it plugged in to 110v shore power. It will give a trickle charge that is just to maintain battery. Depending on your battery bank would depend on how well I treat them. If you have 1 interstate battery then no worries. If you got about 1000 dollars in batteries then I would read everything you can.
All in all. No worries just leave it plugged in , it will not kill over your battery. It may make it last only 3 or 4 years vs 5 years. But at 75 dollar battery I would not get too worked up.
