I don't know if this is relevant.? ?But one of the stated characteristics of Leclanche cells was an initial open-circuit voltage of about 1.4 V, which rapidly falls off.? Whereas carbon/zinc dry cells are supposed to be a little above 1.5 V, and all the ones I played with, measured close to 1.6 V when new.
?
And I still wonder why the only person in the world I have ever seen call them Leclanche cells, is here in this group.? Nobody else ever calls them that.? Why is that?? Is it because few of the people I know are chemists?? But surely many of them are engineers, and none of the engineers I know ever called them that.? Even some chemists don't call them Leclanche either.
?
I have your word, or I have my years of experience, to go on here.? Which do you think I am inclined to believe?
There was a long series of letters to the editor in one of the magazines about how to improve charging.
One thing that appeared to have helped was to have about 10% reverse charge during the process.
How does one give a cell a "reverse charge"?? What does it even mean?
?
It implies doing a partial DIScharge first.? Is that it?? I'm assuming it does not mean to discharge until the voltage reaches 10% negative, but like I said, I don't understand.
?
Does it help only with "non-rechargeable" dry cells?? Or does it apply to rechargeables too?
