Something seems fishy. Capacitors voltage versus charge conforms to the equation C= 1/2CV*V with half the voltage you have only 25% of the charge remaining! With a battery, you have the 2 half cell potentials that sum to the rated voltage. As you discharge, this is a flat line voltage until the charged element is depleted and it goes to zero, (discharged). This has the ring of a scheme to get investor $$
