Query: Nikon EN-EL3e Rechargeable Li-Ion Battery

The Nikon D90 is my first DSLR. I've had 2 digital cameras before this--the Sony F707 and Panasonic DMC-FZ50. This battery lasts forever compared to the other cameras--maybe because it doesn't need to power an LCD screen. I bought a second battery but haven't needed it yet. I shot over 400 pictures in the last month and it still has over half its life left.
