Thus this amount of mechanical work, plus an equal amount of energy from the capacitor, has gone into recharging the battery. Expressed otherwise, the work done in separating the plates equals the work required to charge the battery minus the decrease in energy stored by the capacitor. Perhaps we have invented a battery charger (Figure (V.)19)!

The most significant advantage of this is that a 3V capacitor now will still be a 3V capacitor in 15-20 years. In contrast, on the other hand, a battery may lose voltage capacity over time and repeated usage. Also, unlike a battery, they have a higher power throughput, which implies it can charge and discharge in a fraction of the time.
