Thanks to all who replied to my original post ~ 2 weeks ago.  After extensive 
searching, reading and talking I've learned a lot and have been successful with 
the task of battery replacement.  Yes, you can purchase new replacement packs, 
both NiCad & NiMH (at least for the FNB-41, 42 & 47 packs), and you can save 
~33% by purchasing replacement individual cells (with attached tabs) or ~15% by 
purchasing pre-assembled batteries and installing the series connected 
batteries yourself (2 solder connections).  The Yaesu battery packs identified 
above use 2/3A and 4/5A size cells.

Opening the cases is easy if you first freeze them for at least 24 hrs.  Then a 
sharp "rap" on a side with a rubber mallet pops an edge of the 6th-side plastic 
from the primary 5-sided case.  

For those who want a more detailed, step-by-step instruction and/or battery 
sources, please contact me directly.
