I doubt they're still being made, but you can probably get a definitive answer 
from Pulster or GoldenDelicious. The SANYO UF653450S they contain still seems 
to be available, so sticking the controller board on a new cell should be 
possible. Of course they could be old stock too. My reading of the BQ27000 
datasheet is that it'll get a power-on-reset when the new cell is attached, 
and should then learn the new cell capacity. I may have missed something 
important though.
