        Hello Tom, we were saying ! 

 TW> Well after reading about the Voltage end point differences between the
 TW> NiCAD and the NiMH cells I can understand why. The user counld be
 TW> taking a chance on damaging the radio as at times
 TW> overcharging(overheating) the Battery can cause caustic chemical
 TW> leakage.

        The battery pack on this Icom is removeable and I could slip it of
  for the first few recharge and thus monitor the temperature, by hand
  feel. Warm would not matter, hot would. There is a bit of fine soldering
  to be done to rebuild it and also, I will have to take notes/photos as
  there are some current limiter and diodes to also re-insert in the pack.
  I looked at it for a while in April and it seems to me that the 11th
  cell is connected to a "monitor" of  some sort as 10 x 1.2 is 12 v and
  that extra cell would be redundant. Maybe that is the protection that
  controls the charge as I mentioned before. icom is know for making
  quality apparati. ( Plural of apparatus ? )
     
 The BIOS on this Thinkpad got updated today.
  Still runs !
