Well, I still have to do my testing.
Filling a 8GB card with 720p video (about 26:10 min) didn't show up on the battery meter (still showed three bars afterwards). My gut feeling is that one battery would be good for 1 hour of video. But don't quote me on this.
Maybe you can get a better response from somebody who has tested it.
