Well, I guess the answer to my ooriginal posting is that there is no
strong opinion on Eveready vs Rayovaac.


Not sure what year, but we had a medical product which required C, or AA
batteries, or was that AAA? sorry can't remember which. We found the
longest lasting was Ray-O-vac, but they had a 'leakage'problem that bit us
every now and then. The second was Everaedy, lasting [from memory] around
80 to 85% as long as ray-ovac. And Duracell was a major joke! cost as much
as everready, but lasted about half as long.

I'm sure by now these companies have solved their ills, sorted out their
battery chemistry and packaging, and are all equal now.
