Dave:
If the electrolyte is covering the plates and strong (specific gravity
of each cell approx. 1.260) you should have no issues with the batteries
doing this.
When I go aboard my boat over the winter (on the hard), I plug in the AC
power and give the batteries a charge. At our club, given the close
proximity of the boats stored on the property, you are not permitted to
leave the shore power connected to an unattended boat.....if one boat
caught fire, many more would also. In case someone deliberately or
unintentionally left their power cord plugged in, the night watchman
makes his rounds of the property and disconnects any he finds.

Windstar has two parallel group 31 batteries as the house bank, and a

For winter I top up the electrolyte , and leave the shore power cable
connected to the well-covered boat, coiled and hanging from the prop
shaft. Charger turned on.
Every month or so I emerge from hibernation and connect the boat
overnight to an outlet in the yard via a cheater cable to top up the
batteries.
Seems to work fine. Can anyone see any issue with this approach?
Thanks.
