I had a similar problem with my Uniden phone.  The battery pack
consisted of what sounds like the same pyramid configuration of cells.
I couldn't find a replacement, but I *did* find a ni-cad battery at
Radio Shack that I could modify.  The Radio Shack battery was also
three circular cells, but stacked rather than arranged adjacent to
each other.  I ended up cutting the sheath off the stack of cells and
soldering jumpers across their contacts.  Works great!  Now my only
problem is lots and lots of RF noise around my apartment, but that's
another story...

It strikes me that the Radio Shack battery cost considerably less than
the $12 Robert Hamer reports, but I could be having a memory lapse.
