In practice high output alternators make a big difference getting up

So do Larry, Peter and myself. (Well, larry doesn't live on one, he
just voyages).

Frankly, in my experience a 110 amp alternator and a 440 A.H. battery
bank is overkill,

Well, I've got two 110 amp alternators on a 510 AH bank and I think
that's about right. My experience is that I can bulk my batteries
quickly with my 110's. Sometimes I top them off with solar and
sometimes I work them in the 80%-50% range. Every week or so they get
a full charge and that does take a long time, but still less time than
it would with a 60 amp unit. YMMV.

During your bulk charging stage what voltage are your batteries
reading and how many amps are you charging at?
