I own a HP11C, HP16C, and (believe it or not) a HP 25.  The HP 25 is the oldest
and uses (yes! it still works!) rechargeable NiCads, but it also had a charger
to go with it.  It seems with time that the NiCads gave way to Silver Oxide
batteries.  Both my 11C and 16C use them.  Once I had to replace the cells in
the 11C (*much* easier that 28S).  I made the mistake of using Alkalines.
They died within a few days.  Then I noticed that the owners manual recommended
Silver Oxides.  I used them and have never had a problem yet.

Question:  Obviously NiCads are NOT the answer for the HP28S.  Has anyone
           thought about Silver Oxides??


All responses appreciated.
