I used Sanyo eneloop AA batteries in my D7000 grip w/o any issues but they only hold a charge for about a week then need to be replaced even if no photos taken with my D7100?
I use eneloop in GPS devices and lots of other devices and they last very long. They have a very slow discharge rate which is why I use them. I have never used the Nikon OEM battery so maybe I need to test that but has anybody else had issues with such rapid power drain?

Have you checked custom setting d12, and ensured that it's set to HR6 (AA Ni-MH)? It comes by default set to LR6 (AA Alkaline), or at least mine did, which would cause exactly the symptoms you're seeing.
There may be a short-circuit in the grip or the camera. Try the Nikon battery in the camera without grip attached. If that battery depletes in a week, the problem is in the camera. If the battery hold its charge, the problem is in the grip.
Once you know where the problem is, you can take steps to get it fixed.
Of course, it's always possible your particular AA's are bad. All it takes is one bad cell to drag the others down the drain.
