   Well crazy or not, I recommend that no matter what battery type you 
decide to go with, install a _battery holder_ and forget the stupid 
notion that batteries should be soldered down.  I'm sure that it had a 
valid reason at the time most manufacturers were doing it, but you can 
now get some nice battery holders with snap on lids that will prevent the 
battery from moving.  And then replacement will be a snap later (when the 
battery goes dead again).
   Check out my battery mod to the OB-X I sold here:

   I think you can see it in one of the last pictures on the page.
   As for voltage, it depends from one manufacturer to another.  I've 
seen it range from 3V to 3.6V and up.  If it is one of the charging 
types, I've heard of people ripping the charging circuit out in favor of 
a static system (prevents battery leakage, I guess).
