Equivalent Capacitance in the context that you use it can simply be called capacitance. Capacitance can be defined as ΔV/Q. This is true for any capacitor or network of capacitors. If a circuit behaves in a purely capacitive way then it HAS that capacitance, rather then being equivalent to that capacitance.
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.
Due to capacitor manufacturing tolerances, the capacitance can vary between 0-10% [IEEE] or 0-15% [IEC] of the name plate value. The voltage at which the capacitors are applied can vary +5% or even up to +10%.
