I've had my boat on the hard since Oct. Like most marinas, this one won't allow a trickle charger or any other electrical hookup on an unattended boat in their lot. I figured with the low discharge rate of 8A8D AGMs, I'd be OK, even with the tough winter here. Well the port bank reads 10 volts and and the starboard is 3. Every breaker is off, as I left it. I checked on the boat regularly and nothing has been running over the winter. Bilge pumps have been idle--the boat is shrink wrapped and no rain has gotten in.
I know far less than I should about this boat's electrical systems (been focused on learning everything but electrical, I'm afraid). I have a receipt back home I can dig out to find their age, but I think the AGMs are about 5 years old. It looks like there's a two-battery bank for each main engine that also provides 12 volts to the house. There's a single 8A8D for the Westerbeke genny.
So my questions are:
Thanks in advance.

So my questions are:
- How likely is it that these batteries are toast? Should I even try to recharge them?
- If it's worth trying, how would I go about trying to charge them? The Xantrex 40 charger is hard-wired into the boat and it's a 50-amp service. I don't have an adapter or shore source within distance to handle that. (I can string about 150 ft of 110 to the boat as long as I stay with it.)
- Should I put a charger directly on the batteries and just be prepare to spend the day up here monitoring?
Thanks in advance.
