A certain fully-charged 9.0 V battery can provide a total of 6500 C to a circuit. How much energy does the battery store when fully charged? (Note that the battery can store the amount of energy equal to the amount of total work it can do in pushing all of that charge through the entire voltage landscape of the circuit.)
