Steve,
I did my NiMH conversion before the FAQ and other references now
available. I used all cells of both Varta 9V batteries. The logic went
as follows:
1. Motor Drive can use both M15v and M18v power supples
2. M18v uses 12 cells - either NiCad or Alkaline
3. Alkaline run as high as 1.6v when new
4. 12 x 1.6 = 19.2v
5. 7 x 2 = 14 (#cells in two 9v Varta's) x 1.4 (approx full
charge voltage per cell) = 19.6v. I think "close enough"
6. With a little juggling, it fits (a big test)
7. It works ! (Mine about 2 years now)
8. This configuration gives more output (more cells) and is much
more "user friendly" (NiMH cells) and weighs less. It sounds like a
better fix to me.
note: In step #6, one of the Varta's must have 2 cells "unfolded" for
space configuration.
