HoudiniHarry - the chemicals should only be manganese dioxide, zinc and carbon rod, with potassium hydroxide as electrolyte, no different from many bateries today still, not too dangerous unless youre eating them :lol:
Usually its only a carbon rod and manganese left, the zinc must fall off or eat away. Some must have a tiny bit of charge if tgey are wet and contain a salt of any sort to help conduct a current through though. Ill try on some of the better cells
