Thanks Chuck!

To answers the unstated facts.

I don't have a maximum charging time, I am in no hurry.
And on that note.... If I run the engine all day, I shouldn't need to
charge overnight right? Wont the alternators top of the batteries
during the day?

Assuming alternators are big enough (or that battery banks are small
enough) I would generally expect that 8-10 hours of above-idle engine
running should top off the batteries nicely. This does depend on the
charger, too. A smart charger will get your batteries up to 85-90%
charge more quickly than a simple automotive-type charger. Beyond that,
both types of charger will take about the same time to get you near 100%
charge.



My current battery bank capacity is somewhat moot as I am replacing the
batteries. They came with the boat and are at least 6 years old. The
age is not itself a problem, but they wont hold a charge, so I am
replacing them.

My generator is SUPER old, but it was manufactured as a 4.7 kw unit.

Ought to handle just about any charger on the market!
