Sorry I forgot to post what batteries I use, they are the Rayovac 4.0 Lithium rechargeables. Here's a link to see
Amazon.com: Amazing Rayovac 4.0 Rechargeable AA Batteries: Electronics what I am talking about. It's for a 4 pack and they have a great lifespan, only thing is remember that if you use the flash, live view, or video recording, they will not last as long as if you were just snapping away. Also I have shot over 10 minutes of video and 2500 pictures without needing a recharge. The package states 1900 pictures but their just understating their product, overall I am extremely happy with them, and would recommend them to anyone.
