No. In the context I was looking for a single word that would make it clear enough what I was trying to say, without unnecessarily filling the page with a reasonably irrelevant discussion of battery chemistries. Mayhaps I could have said "Zinc Anode chemistry" or some such but even that would have been confusing (and it still would have included eg Mecuric Oxide / Zinc cells). For those who feel inclined to benefit from this interesting digression, here's a fairly good discussion of the Zinc / Alkaline / Manganese Dioxide (with added carbon)(which takes it back towards Le Clanche) technology cells, from the company that first commercialised them sucessfully. http://www.duracell.com/oem/Primary/Alkaline/ Russell McMahon -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
