Battery capacity is a measure of the amount of energy that a battery can store and deliver. It is an important factor to consider when choosing a battery for your device or system. The capacity of a battery determines how long it can run without recharging. The capacity of a battery is usually measured in ampere-hours (Ah) or milliampere-hours
The capacitance and the voltage rating can be used to find the so-called capacitor code.The voltage rating is defined as the maximum voltage that a capacitor can withstand.

The capacitance of a capacitor is a parameter that tells us how much charge can be stored in the capacitor per unit potential difference between its plates.

• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The is equal to the electrostatic pressure on a surface.
C = Q/V If capacitance C and voltage V is known then the charge Q can be calculated by: Q = C V And you can calculate the voltage of the capacitor if the other two quantities (Q & C) are known: V = Q/C Where Reactance is the opposition of capacitor to Alternating current AC which depends on its frequency and is measured in Ohm like resistance.
There is absolutely no way you can possibly know the capacitance value to 8 significant digits! Think about it. Even a fraction of a degree temperature change will cause more change in the stored energy of a battery than 1 part in 10**8, and of course the initial accuracy is nowhere remotely close to that. Your conclusion is simply absurd.
