What's in a battery, these days?
When I was a lad, old dry cells were a source of interesting scrap,
carbon rods, zinc flashing, brass strips and brass terminals. Are zinc-carbon cells still sold today, or are the AA, A, C and D cells made up of more insidious (and poisonous) compounds? The metallically-sealed cells look a little more daunting than the bitumen-sealed zinc cans of yore. What do we get when we rush down to our local hardware stores apart from fork handles? PS. I'm interested in getting hold of one of those wet Leclanche cells, the sort with the baekelite moulded tops, that were used to power door bells. Anybody got one for disposal? ISTR that there was no depolarising agent fitted which served a useful purpose - that of preventing annoying long presses of the bell-push. |

I thought the police didn't bother ringing the doorbell as you are so well known to them? -- huLLy Mobile phone 07976 123278 ICQ 136-987-925 |

After replacing MonoCalculus with a small shell script on Sunday 27 Nov
2005 11:48, the following appeared on stdout: Are zinc-carbon cells still sold today, or are the AA, A, C and D cells made up of more insidious (and poisonous) compounds? Just don't start prying Li-Ion cells to bits. They're rather nasty if you manage to puncture them. -- Radio glossary #13 Integrated circuit: You have the only one in existence. This theory will be borne out when you try to obtain a replacement. |

If you buy the cheap cells ($1.00 a dozen or so) then you get the old style. But if you buy Alkaline batteries you get a cell that has the Zinc in the center and Carbon around the outside. Most of the Zinc and Carbon is powdered in the Alkaline cells Bill K7NOM |
