   I still haven't done much with them The one I played with did seem to   
   charge OK.   
   So many projects, so little time.

   I am doing an experiment with a NiMh battery pack in an old panasonic   
   wireless phone designed for NiCd's. I bought some NiCd replacements that   
   turned out to be NiMh. Fried a couple of those in the phones. They'd   
   last about a year, then quickly and completely die from overcharging. I   
   put a AC timer on one phone supply set for an hour a day with the last   
   NiMh battery. It started about 2/3 charged, and has stayed there for 2-3   
   weeks so far. Maybe they will last a lot longer. I will adjust the   
   charge time if the charge level drops.
