that is the battery you need

you need to a local camera shop and buy from them. I know that Ritz Camera (also called Wolf Camera) stores are in pretty much every major city. They would have such a thing.

You can also try best buy, but I don't know if they carry DSLR batteries

The type of battery that you need is called an EN-EL14 Rechargeable Li-Ion Battery

You can purchase these batteries at any camera shop, Best Buy Store, or Radio Shack Store. I have not seen this particular battery at Walmart stores in our area, but the selection varies by store.
