Good to go, probably. If necessary, turn it on when you start out, turn it off when you get the mainland dock. Charger on, all should be good.

If you didn't have any parasitic loads at play, you could find your batteries are still amost topped up. We've been on the hard for about 5 months before (Odyssey AGMs) with no appreciable self-discharge. I'd expect the Lifelines to be the same.

Prior to then I had always thought only lead acid batteries should be given an equalizing charge.
FWIW, Lifeline is the only AGM maker -- that I know of -- that recommends equalizing.
