    RPM depends on alternator brand and model number, and more importantly, it depends on the load, the battery, and its state of charge, and its health and temperature.

    in other words, at a fixed RPM, the output voltage varies with the state of charge of the battery. And the temperature.

    AND, alternator RPM is not the same as engine RPM as that depends on pulley sizes.
