Battery capacity is the total amount of energy a battery can store and deliver over time, typically measured in ampere-hours (Ah) or milliampere-hours (mAh). According to the U.S. Department of Energy, battery capacity reflects the energy storage capability of a battery system and is a key performance metric for evaluating battery technologies.

We can find an expression for the total (equivalent) capacitance by considering the voltages across the individual capacitors. The potentials across capacitors 1, 2, and 3 are, respectively, V1 = Q / C1, V2 = Q / C2, and V3 = Q / C3. These potentials must sum up to the voltage of the battery, giving the following potential balance:
This 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.
The total energy is the nominal voltage multiplied by the nominal rated capacity. However, if you have been through the Battery Basics you will have realised that the battery cell and pack do not have a linear performance and this is true for the usable energy.
That fact that the battery may also store that much energy does not mean that there is a capacitor equivalent to a battery. While an ideal battery maintains the voltage across its terminals until the stored energy is exhausted, the voltage across an ideal capacitor will gradually approach zero as the stored energy is depleted.
The battery energy calculator allows you to calculate the battery energy of a single cell or a battery pack. You need to enter the battery cell capacity, voltage, number of cells and choose the desired unit of measurement. The default unit of measurement for energy is Joule.
Your formula for energy content of a capacitor is correct. Whether the energy is all usable is another matter. Your battery energy formula is correct for an idealised battery. What you have calculated is not an equivalent capacitance but, instead, the capacitance required to store 9kJ of energy at 2.7V.
