--- Quote from: MK14 on February 04, 2022, 12:56:58 am ---I'm now worried, because the wiki article seems to hint/imply/say (it is not that clear), that zinc (non-alkaline) batteries, older than 1996, may have used Mercury, to preserve their shelf-life. Which puts a possible twist on the OPs batteries. If their amazing life, is because they have Mercury coating the Carbon section. Then I'd be worried about possibly toxic Mercury, and its possible effects on the environment. --- End quote --- Actually, the danger to individuals from mercury is rather overstated, unless you ingest it. I took apart countless zinc carbon batteries in the 70's to get the carbon rods out of them, and quite freely got the black electrolyte paste and other contents all over my hands. I also played with liquid mercury and dipped my hands in a bath of the stuff to see how it felt (weird, in case you are wondering). So I would not consider a zinc carbon battery from before 1996 to be a hazardous items. After all, they were manufactured by the million. |
