Max and all, surprisingly zink carbon cells are still around they're sold as "heavy duty" 9 volt batteries for sure, I've seen some smoke alarms which call for them, forgotten why.
Of course in the old days, when vaccuum tube portable receivers were about, they had zink carbon packs of seriesed cells that went up to 90 or even 120 volts I believe. Not sure what the individual cells in those packs looked like, but i do remember 22.5 volt packs that were the cross section of a 9 volt but about twice as long and had a connector on either end. They were made up of little flat cells as some 9 volt packs still are. These were called B batteries as they supplied the high voltages or B plus for tube rigs. That's why we have A and C but not B cells today. Havn't seen one of those 'telephone' cells in years, and they had such neat screw terminals on top, were fun for messing around. tom Net-Tamer V 1.13 Beta - Registered
