Customer ServiceThis logically suggests that when you talk about an "equivalent capacitance" to a battery that you mean a capacitor that stores or can deliver the same energy as the example battery. In theoretical terms your calculation is correct for an idealised battery (constant voltage throughout discharge, defined mAh capacity) and an idealised capacitor.
So to establish the required capacitance for a given battery use. In this case, discharge to 0.54V would increase capacitance needed only by about 5%. For an endpoint voltage of 1V you have remaining energy of 1V^2 / 2.7V^2 =~ 14% energy remaining.
A battery and a capacitor are hardly equivalent. A battery has a voltage that's a function of the chemistries of the materials inside it. This voltage is constant. As the stored energy in the battery is exhausted, the voltage decreases some.
To measure a battery's capacity, use the following methods: Measure the time T it takes to discharge the battery to a certain voltage. Calculate the capacity in amp-hours: Q = I×T. Or: Calculate the capacity in watt-hours: Q = P×T. What is the C rating of a battery? The C rating determines the rate at which the battery discharges.

It is a handy tool that helps you understand how much energy is stored in the battery that your smartphone or a drone runs on.
Capacitance is just a ratio of electric charge (the integral of current) to voltage: C = Q V C = Q V The SI unit of capacitance, the Farad, is a coulomb per volt: F = C V F = C V (note here the C is coulomb, where above it was capacitance) This says nothing about how much energy the capacitor can hold.
