Ok, I went on that Amazon link. The picture shows the battery and its different than my original. It doesn't show the 3.9 watt hours and it doesn't show the 4 Alpha characters under the holograph.

Makes me wonder if its really a Nikon branded battery. I would imagine that Nikon does not make batteries but instead gets someone else to do it. That would be fine as long as a consumer knows it is equal to or better than the Nikon original.
