[ARC5] Batteries That Do Not Corrode?

[Tom Lee]

Yes, that's correct. Ammonium chloride ("sal ammoniac" in oldspeak) is 
the electrolyte in carbon-zinc batteries. It may very well be that a 
little marketing effort went into deliberately confusing the public into 
thinking that "zinc chloride" was something different (and perhaps 
better), but it's all the same thing.
