Mechanical regulators for generators had current limiting and voltage relays.
Mechanical and electronic regulators for alternators have voltage limiting
only.

Batteries used in a old generator system seemed to last forever while the same
type/brand battery would have a limited life in a alternator system.  Lead
acid automotive batteries like a short/high current discharge and a long/ low
current recharge.  The current limiting a generator provides helps battery
life.

A alternator is current limited by the size of the stator windings and , to a
lesser extent, the size of the rotor ( field ) windings.
