Talk:Leclanché cell

Untitled
I intend to make some changes to this article. See Depolarizer and Primary cell terminology for further information. Biscuittin 10:24, 3 June 2007 (UTC)

Isn't the cathode of an electrolytic cell the positive terminal and the anode the negative terminal? Nivvedan (talk) 11:23, 4 January 2008 (UTC)

Depolariser reaction.
The reaction for the depolariser in this article is at variance with that in the Zinc-carbon cell. One is clearly incorrect. My belief is that this article is incorrect and that the other is right, but I can't find a suitable reference. 109.145.22.224 (talk) 15:59, 21 April 2012 (UTC)

Chemistry
It appears that the following reaction is not balanced for protons nor for electrons:

Zn(s) + 2 MnO2(s) + 2 NH4Cl(aq) + 2H2O(l) → ZnCl2 + 2Mn(OH)2(s) + 2 NH3(aq)

I suggest that we replace it with

2Zn(s) + 2 MnO2(s) + 4 H+(aq) → 2Zn2+ + 2Mn(OH)2(s)  — Preceding unsigned comment added by Friendly naif (talk • contribs) 20:55, 13 November 2015 (UTC)

Recharging
Is it known how these batteries were charged and recharged? I am particularly interested in their uses in country houses, where they powered discrete electrical systems such as those for servants's bells and internal telephones. Articles on the batteries indicate that they were not long lasting, sometimes losing power during the course of a short telephone conversation (as the article here points out). Some country houses still have examples of the batteries but with no evidence as to how they would have been recharged. I've scoured several journals and other sources for information on this but have found nothing. I'm sure it would help other researchers if this information was available here.

 * Leclanche batteries were primary batteries. The zinc rod slowly dissolved (when a current was drawn.) Once the zinc was totally dissolved, the battery had to be re-charged with a new zinc rod and a new porous cup with the carbon.
