For that alone, his MC trickle chargers will do the job.

also will need to charge them between sailings once he
gets
his sails on next decade or two.

Scotty,
My engine or my onboard charger (when on shore power) can
each charge the
batteries from April to November. I'll keep them in my
basement over the
winter though, so I'm thinking of that scenario. Optima
seems pretty adamant
about not exceeding 13.8 volts or 1 amp. Otherwise I would
have just thrown
the MC charger on them.


My MC charger puts out 1/2 amp, and won't overcharge ( so
they claim). Not to exceed 1 amp? What does your engine
put out?
