Time taken to charge the capacitor
$begingroup$ A possibly more descriptive version of your last sentence: after five time constants, the capacitor is charged to 1-e^-5 = .993 of fully charged (at the given voltage), which is usually considered charged. $endgroup$
RC Discharging Circuit Tutorial & RC Time Constant
As we saw in the previous tutorial, in a RC Discharging Circuit the time constant ( τ ) is still equal to the value of 63%.Then for a RC discharging circuit that is initially fully charged, the voltage across the capacitor after one time constant, 1T, has dropped by 63% of its initial value which is 1 – 0.63 = 0.37 or 37% of its final value.

Learn Electronics/Capacitors
The capacitor is then fully charged, the voltage at its terminals then being equal to the supplied voltage. Usually, if left alone for some time, a charged capacitor loses its charge slowly. Note that a voltmeter connected across the terminals of a capacitor represents a "load" and in some calculations may not be neglected.

Understanding DC Circuit Capacitor Behavior
When the capacitor voltage equals the battery voltage, there is no potential difference, the current stops flowing, and the capacitor is fully charged. If the voltage increases, further migration of electrons from the positive to negative plate results in a greater charge and a higher voltage across the capacitor.
