I was tracing my AC wiring this last weekend and finally found the cut end of the lead for the battery charger... meaning I have no battery charger.

Looking for recommendations for a charger... right now just something basic; to hook up to dock AC power to keep the batteries topped off.

Thus far I have managed just fine on running the engine once a week... I have been contemplating a small solar charger.

So any ideas/suggestions/and of course, recommendations on what to avoid?

It's pretty basic right now... two group 24 batteries tied together with an isolator and through a battery selector switch. I have an alternator that puts out 50 amps and has done fine thus far.
