A 12 V battery is rated at 200 Ah (Amps hours). How much total energy can it supply?

2. Relevant equations

P=IV

3. The attempt at a solution

First I did E = 1/2 C V^2. (Got 4,320,000 J, although I'm not sure if that is correct). But now I need to convert it to kwh so my question is can I use P = IV in this manner:

P = 200 Ah * 12 V

P = 2400 Wh = 2.4 kWh

or do I need to manipulate my original energy finding?

4,320,000 J != 2.4 kWh so one must be wrong
