I agree that on the 3rd stage the voltage should drop to "float" voltage. I
would think that 12.9 to 13.1 would be good. Continued operation at 14.4
volts will boil out the water. Perhaps their definition of 3 stage charging
is different from mine (and yours).

Hi group,

I bought an alternator with a built-in 3 stages regulator. The voltage
coming out of it seems to be constant at 14.40v. The batteries are
fully charged now and the charge current is very small (1amp) but the
voltage remain at 14.40v. Is that normal?. I am told by the
manufacturer that it's the way it should be. I would have thought that
the voltage should come down to a lower level once the batteries are
full.

What do you think?
