My complete table (copied laboriously from the original--no photocopy
available then) also includes weights, volumes, cutoff voltages, and
some other stuff.
Please note that the above data was from ONE manufacturer and is very OLD.
Surely cells have been much improved since then. It would be interesting
to ask Eveready for an updated chart--if anyone does, please post.
