Just yesterday I visited the Nikon West Coast Repair Center. They recently moved from the airport to Hollywood. A 20-minute drive. I had my D7000 in to see why the battery was draining.
They are really nice folks. Willing to talk to you. Camera has another 2 months on warranty. It turns out, that nothing is wrong with either battery or camera body.
The only conclusion I can draw is that I am doing something to pulls too much electricity. I rarely use the pop-up flash. So, I just went through the obvious menu settings that limit juice. I dimmed down the LCD and Control Panel. I cut the display time for INFO, Playback and one or two others.
Is there anything I overlooked to conserve battery charge? Oh, and I rarely "chimp" after taking a shot.

Some other tips . . .
1. When walking around with the camera on your shoulder, keep you finger off the shutter button. Lots of photographers rest their hand on the camera grip while walking and inadvertently keep activating AF so that the camera never goes to sleep between shots.
2. When stowing your camera in the bag while walking or traveling, turn off the camera. If there's anything stowed on top of the camera while its still on in the bag, in some situations there might be enough pressure on the shutter button to repeatedly activate AF.
You haven't mentioned how much battery life you're actually getting, and you haven't mentioned how many shots per charge you're getting.

Let me throw some numbers at you —
Yesterday, I returned a 3rd party battery grip (amazon) because in one 7-day period, the battery charge dropped from 100% to 24%. Less than 20 images were shot, and the camera turned off at all other times. And I wasn't walking around with it.
This happened twice to me. Same numbers on the battery charge. I tried it once with the Nikon battery in the body (grip attached). And then once again with the battery in the grip. The EN EL-15 battery.
That's why I took the D7000 body and EN EL battery to Nikon a week ago. To ascertain if the fault was in grip (which spooked me anyway by being a non-Nikon accessory) or the fault of camera electronics and/or the battery itself.
No more Chinese camera accessories for me. Aside from this, I wonder if I am setting menus too often. Could it be "operator error" that causes battery drain.

You can set and reset menus and configurations 50 times a day without even nudging the battery life. The third-party grip is the culprit, no doubt. The reason for the power drain is likely to be found in its main connector, which is a common problem with several so-called off brands.

What brand grip did you have? I have a D7000 with a Meike grip that does not get used that much but batteries seem to last forever. I have a Pixel brand on the D800 and Ziekos on the D90. The D800 goes through batteries pretty quickly but that is the same with or without a grip, it just pulls a lot more current than a D7000.
How did Nikon measure the current drain of the camera? If you took the grip off, did the battery last for 1000-1500 shots? There still maybe a problem with battery or camera unless they did a current measurement. I have not found any camera techs who were also electronics techs, and the job does not entail any electronics work. If a problem occurs in some module or if one is suspected, the entire assembly is replaced, or the next until the problem goes away.

Stan, the grip was a Pixel Vecta. Bought from Amazon. The repair place was one of only 2 official Nikon offices in the United States. Their printed report stated: No problem found within standards. Checked battery drain. CKD AF operation. CDK Flash operation. CLN CCD. General Check & Clean.
Since my only problem disclosure to them was battery drain. they went far beyond that on an 8-month old camera, There was a recall in Sept for the EN EL 15 battery, so my battery is really only 5 months old.
Since they are Nikon, I would guess they are knowledgeable about electronics. I'll report back here after I've shot for a month or so. Currently, however, I'm only shooting about 200+ images in that period.
Bob, I joined Nikonians in May or June, so your warning about about off-brand grips might have appeared before then.
I'm ordering a new Nikon MB-D11 this morning. I want the warranty and I don't want drama. Digital drama or any other kind.
While waiting for my MB-D11 grip to arrive, I did some research on this issue.
Thom Hogan's eBook on the D7000 (800 pages long) had all the details. It turns out that even when the camera is turned off, some viewfinder options remain on and cause a current draw. These viewfinder items are Warnings, Gridlines. Another big power hog pertains to LCD and Control Panel screen duration during Replay, Menus, Info and Metering.
What others have said here about resting your finger on the shutter button unnecessarily is also important.
Here is what Thom Hogan says to reset in order to prolong battery charge:
Menu C4, D2 (off) D4 (off). Set C4 as short as you can stand. I was surprised how quick a readout satisfies my "geek urge". 4 sec is enough for me. Playback (displaying an image on the LCD after the shot is taken) really sucks up the power. Resist the temptation! Don't be a "chimper". Be a grown up. Save power.
I'm on day 4 with the camera off. Charge still registers 100% As Gene Wilder exclaimed in the Frankenstein movie ....... It's alive. ALIVE!
