Well, it's a dry subject. Unless you're interested in it. The history of dry cells actually is quite fascinating. Back in the bad old days of tube radios, they did actually make portable radios. All those walkie-talkies and handi-talkies of WW II didn't have a transistor in them. For these applications dry batteries had to be made with a great many cells, and potentials as high as several hundred volts. Those are all gone now. SBHarris09:20, 19 January 2007 (UTC)[reply]
Great improvement from the earlier version. I've rephrased the description of carbon-zinc cell and chemistry and hopefully made it clearer. Ian10:12, 16 March 2007 (UTC)[reply]
