John,
Thnaks for posting the discharge characteristics (or at least the specs) of
the button cells. Maybe I missed the data if it had been posted some time
ago...
What really inpressed me was the big difference between EXP76 and #357
design performance. I know that John Hermanson has been telling us for
years that the #357 is better, but the notes for each battery type really
get the point across. If you read the simple specs you'd think that maybe
the EXP76 was better, since it shows a higher MAh rating...
