Snap! I did the same in 2002: http://www.johnhpanos.com/nodal.jpg . It's a good method for non-SLR cameras. Except, your two batteries only 6 inches apart is far from being the worse case parallax. *Both* batteries will exhibit parallax shift and what you are seeing is the difference between these two shifts. It's better to compare the near battery with something as far away as possible. I use a window frame in the house across the road as the far reference point.
