I just recently started using LV on my D700 and was amazed at the sharpness. I was using my 400mm f3.5 on it, with the zoom + button. I barely got a dozen shots before I needed to change batteries. I can shoot all day and get 500 shots before changing batteries normally. I may have to have my MD-10 attached to use this feature. I missed a sweet hummingbird shot when my first battery went down, but I got this shot.
LV eats batteries like candy. I've found I can get about 1 hr max continuous using lv and a freshly charged battery. Keeping the lcd on and the sensor powered on really uses a lot of power. I got a second battery just for that use.
That was one of the first things I noticed when I got my used 700. I also shoot with a 300s and I get much longer battery life in LV with that than the 700. But yes LV will suck the life out of the batteries.

I had a similar experience four weeks ago shooting water falls at Ricketts Glen in Pennsylvania. The battery fell more quickly towards 50% than I'd expected, and then died. Ok, so LV eats batteries, I learned, but the backup battery charged to 100% didn't last a minute!
So while I can understand that LV uses more juice it seems to me that something else might be going on too.
Btw, both batteries were successfully recharged and work fine in the camera since. Next time I'll bring the MB-D10 and see how it works with 8 AA's.
