If you leave it plugged in, make sure to check the water level in the cells often.
My previous trailer had a pair of optima blue tops, when I wasn't camping I disconnected them and reconnected and plugged in a couple of days before heading out. They lasted about 8 years, current rig has a pair of Interstate GP 24's. They don't get disconnected, trailer stays plugged in and water checked monthly. They are good and only about 2 1/2 yrs old.
