Hey Nathan, a yes these things are usually called either 12V, 24V, 48V turbines. The actual voltage will vary between 0 and say 14.4V for a "12V" turbine depending on the speed of rotation of the turbine. So as the wind picks up the turbine spins up and the voltage climbs up to about 13.1V - 13.5V as you say when the batteries can start to be charged. As long as you have enough batteries they should then load the turbine in such a way as to keep the voltage from going above ideally about 13.8V. One then uses a dump load controller and dump loads to stop the voltage from climbing much higher for long lengths of time.
