#11. "RE: MB-D11 Battery Grip Question / Possible issue" In response to In response to 10 Sat 17-Nov-12 02:04 PM by hawaii502160
I just bought my MB-D11 a month ago...my battery "rattles" in the tray also. I have 2 Nikon batteries, and they both do it. The battery is "locked" into the tray with the plastic tab, but there is still enough movement to feel and hear the battery shifting around. I was aware of this problem being reported before I bought it, so it didn't surprise me when I found that mine does it.
