I removed the battery by desoldering it. It turned out to be two button
batteries shrink wrapped and soldered together one on top of the other. I assume
the bottom flat part is the positive side and the bumpy other side is the
negative. (Let's hope so. I've never seen ones quite like them - they are from
Germany that is all I can read on them). I am in the process of obtaining the
NiCd 3.6 V as you said. However, I don't know the term you used in your last
E-mail mignon. The three battery replacment with large capacity sounds great
so I belive I would like to do that.
Your information has been very helpful and I thank you very much.

PS as for the two battery trick from Berk ! Sounds like a good idea in the
future but there was nothing to save right now, all has been lost already.
