I bought an MB-D11 at our big annual camera show last month and was dissapointed to discover that the EN-EL15 has some movement once mounted in the slide-in tray. The movement is sufficient to make an audible noise when you change the camera's physical orientation from "landscape" to "portrait".

Finally got around to taking it back to the retailer today and another one off the shelf showed exactly the same symptoms.

Has anyone else had a similar problem?

To date I have had to wedge the battery with bits of paper to prevent the movement - most irritating and my first Nikon dissapointment...
