High Output Alternators

Can someone help me clarify some issues surrounding high output alternators? I''m not sure I see the logic in having one unless one does a lot of extended cruising where your battery bank is discharged by more than 50%. It seems with three stage chargers, the charging rate is almost always in the range of 15 to 30 amps. If that is the case, the standard 35 amp alternator should be fine.

The only time I can see when a high-output alternator is when the batteries are down at the 50% level. At that point, you might get at higher charge rate. So - if you are off crusing somewhere and cycling the batteries between 1/2 capacity and 3/4 full, you will need to run the engine less. But for someone who doesn''t deplete the batteries below 3/4 full charge - I don''t see it making sense.

Hope that was clear...

Do I have it right?

Thanks.
