Voltage is not the same as energy. Voltage is the energy per unit charge. Thus, a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other because (Delta U = qDelta V).

and then solve. Clearly, this does not depend on the applied voltage since we''re interested in a dimensionless number - the fraction of the final voltage rather than the absolute voltage. For a simple exercise, how long does it take for the capacitor voltage to reach $(1 - 1/e) approx 63.2%$ of the final value?
