Dead Battery & Want to Replace

My battery has gone dead twice in the last month, but after jump starting it it seems to be ok. I still want to replace it, it hasn't been replaced and the car is four years old. Where and what kind to I get and where is it at? It's not easy seen as in most cars? Help Please, I would greatly appreciate it! :rofl:
