"Better than the knock-off's"
Splurge on getting the official Nikon battery. My sister bought an EN-EL3e imitation which seemed to be a bargain choice at first, but several charges later her's seems depleted, while my battery is as good as new.

"Nikon EN EL3e"
Nikon EN-EL3e Rechargeable Li-Ion Battery was purchased as a back up for my new D300 .I have noted that the original battery will not last 3000 shots as indicated by Nikon.Usually i will notice the bars getting lesser after about 300 shots but will still let me get about 500 shots .
This was never a problem with D70 and the battery that came along with it.I used the camera for three years and never felt the need for an extra battery.



"It's a genuine Nikon Battery"
There isn't really much to say. Buy the Nikon battery it will last longer and more charges.

"Good buy!!!"
I just bought a pair of Nikon EN-EL3e at a good price. I have been using one with my D50 for almost three years now and it didn't give me much trouble. It charges quickly and gave me lots of shots. I didn't want to gamble on other brands and stuck with Nikon.

"How do they do it"
This is a backup battery and I am amazed at how use you can get from a charge and the shelf life. I believe this is the only battery that will fit my D-300, but it does not matter. This is the one for me.
