Agreed Ian, but as the battery nears its capacity, the regulator turns the output down, if the battery is nearly full, then the voltage will drop to arround 13 volts, on a flat battery I've seen the meter hovering near the 14.8 volt mark, its the voltage that overcomes the battery's initial resistance.
