Old PC motherboards
In the 1980s some PC used Lithium Thionyl Chloride batteries for the clock. I remember buying them in 1980s for parameter RAM for an Industrial Controller I was developing, no Flash memory then. The NiCd packs didn't have long enough life and also self discharge was 100s of times more than the static RAM standby current.
I wonder are they still made? Thionyl Chloride
One of the ingredients of super glue isn't much fun either. Methyl Isocyanate, I've noticed it lately as an ingredient and wondered. A spill of "Superglue" can set damp cotton on fire.
