That does have rhyme & reason to it -- yes.

(And you are correct in that it takes 2 of these 2.5V lithium cells -- I 
failed to mention that in my original post.)

I suppose it just couldn't have been foreseen by them that SAFT would 
discontinue manufacturing this particular battery at some point down the road.

Still, though, wouldn't manufacturing a device which relies on a sole 
provider for its power cells raise a flag or two during the design process? 
It is not like these batteries are as common as dirt -- like your typical 
Duracell "AA". (Then again, I'm no hardware engineer, so I'm not familiar 
with how these decisions are made.)
