I do not think that 700 mAh NiCds were common those days.

Hmm... I got Panasonic Industrial catalogues from 1990 (!) with their complete NiCd range. Their top-of the line AA product was the P100AAS with 1000 mAh. But this type was not available in the early Eighties. In 1985, years after the Spice production had ended, 600 or maybe 700 mAh was all you could get, both from Panasonic and from Sanyo. At least to the best of my knowledge. That's why I wonder what batteries you may refer to. And that's why I hope I may humbly ask if you're sure it was 1980 and not 1990 ?-)
