    The biggest problem is it implies that the battery actually has that capacitance. Mostly I'm just confused as to why you would try to assign an "effective energy storage capacitance to a battery when using energy storage would work just...

    I'm not sure what you were trying to compare, but it doesn't make much sense to say that a battery contains capacitance. Capacitance is a property of capacitors. I suppose all real batteries will have some equivalent parellel capacitance, but...
