When charged, a capacitor''s energy is 1/2 Q times V, not Q times V, because charges drop through less voltage over time. The energy can also be expressed as 1/2 times capacitance times voltage squared. Remember, the voltage refers to the voltage across the capacitor, not necessarily the battery voltage.
