They look in remarkably good condition, externally anyway. As helius says, they're very tolerant of abuse, and unlike NiCds, didn't suffer from dendrite growth.
They're NiFe so no toxic Cadmium to worry about, with a benign electrolyte too. They probably have significant scrap value.
It would be a shame to see them go to scrap without at least trying to resurrect them. There are enough cells to select good from bad. NiFe were used in the orignal electric traction vehicles early in the last century!
