Used Laptop batteries (HR1 Tupsley)

Batteries that are no longer good for running a laptop are still useful. If anyone has any of the old style (thick - 20mm, 3/4") I can make use of them. They will probably have years of use in my low power equipment. Only the thick type is suitable - the thin ones (about 9mm thick) contain flat slab phone type batteries which will not fit in my devices. Any offers much appreciated, Rod
