hi jim
there is a real neat charger that cycles your battery. takes it up to
charge then desulfides or something when charged. will not over charge
and keeps the battery fresh as the day you bought it new. cost is
around 40.00 and you can get it from northern supply and most battery
stores. it can also keep in check up to 4 or 6 batteries at once. i
would just put in another 110V outlet behind the existing outlet in a
drawer, then just wire it up to the hot side of the starter and a good
ground. it can just stay on board you may want to also install a in
line fuse and a toggle switch to shut it down if need be. c-ya Jonce
