Can a car alternator charge a car battery?
Alternator generates low voltage AC which when passes through diodes becomes Dc and is connected to your car battery. usually battery voltage moves between 9V to say 13.5 V. When alternator runs, its output voltage is usually between 13 to 14 volts which is enough to charge a battery.
