Thanks for than information as I was unsure of the application they were used in. I collect anything that has Chloride on it besides other stuff. Its a shame they were not complete though but there were loads dumped there and the separators to but no tops or filler caps. They were on the Blaydon side of the river. If you don't want those batteries of yours I could take them off your hands as I live down the road from you. I may go back and have another search in that area to see what else is there but loads of these cases still remain there though.
I have been trying to find them on the internet but no joy though but also there was a broken Alcad cell there to and there were nickel iron cells, plastic case ones and not metal. I also found a few broken Chloride cell cases at Marley Hill NCB colliery site, you may remember this place Ed as it closed in May 1983.
