Why is it that rechargeable batteries state the capacity,eg., 2500

Probably because it's not in their interest. Better to show bunnies
going on and on...

Also when one question is answered, the next one is raised. And the
next one would be why do so many one shot batteries give only a
fraction of their rated capacity in real life apps. Some questions are
better left unasked.

Is it really true that a primary cell takes more energy to manufacture
than you'll get out of it, or just an urban myth?

I'd bet it is true - and by a factor of many. Then there's the energy used
to transport it etc.

Of course it's true, otherwise the laws of thermodynamics would be in a
pickle and the universe would probably explode fairly quickly as entropy
would be reversed!
