A capacitor never charges fully to the maximum voltage of its supply voltage, but it gets very close. Example. Below we have a circuit of a 9-volt battery charging a 1000µF capacitor through a 3KΩ resistor: One time constant, τ=RC=(3KΩ)(1000µF)=3 seconds. 5x3=15 seconds. So it takes the capacitor about 15 seconds to charge up to near 9 volts.
