That's the AA version. The question was about 1980's AA NiCds compared to today's AAA (!) Eneloops. Despite the smaller size they still offer twice the original capacity.

But of course you are right: if you compare same-sized batteries the current versions actually offer five times (!) the capacity of the old NiCds. However, the point here was that even the smaller AAAs (as suggested by Dave) perform better than the much bigger AAs from 1980.
