Nikon EN-EL3e Rechargeable Li-Ion Battery for D200, D300, D700 and D80 Digital SLR Cameras

Its a battery. I trust nikon to make it properly, worth the money for peace of mind. works perfect.

This is my second battery for use mostly in traveling. If you travel a lot and do extensive hiking, do yourself a favor and buy a few extras of these. they'll come in handy when you're in the middle of nowhere.

Battery works as advertised. It lasts MUCH longer in a D300 camera than a D200 camera. I was able to shoot 4 football games with a single EN-EL3e battery with the D300 camera and still had charge to spare - in the past I would have used as least 2 or more of the batteries with the D200 camera.

This is a must have for digital cameras. I missed some gorgeous sunset photos once because my battery died just as the colors were at their best. Never again. I always bring a spare battery now. It's a no-brainer.

I got this because I heard the d300 burns through them. To date, I have not noticed that, although I'm not a pro doing full events. Regardless, it's worth it to have a spare.
