Mike,
Thanks so much for that information, I will need all the help that I can get on this. I'm pretty darn good at FLA batteries but this is new to me.
I have not touched the contents of the cells but am removing years of crust from outer casings, there is a thin film of light oil on the tops of the cases with much dust mixed in. I will read your procedure before attempting to clean and flush. I do know not to use mineral water. I keep distilled water on hand for my LA battery sets and I manufacture colloidal silver using distilled water for personal use.
In testing various distilled waters some leave a black oxide on my 4-9 silver electrodes (.9999% purity). used in the colloidal silver manufacturing process. Arrowhead puritas distilled water does not!
This is the only brand that I use
Found this morning:
These are Edison Ni-Cad cells , I googled the model number "Ed-80 battery" and got this:
https://www.osti.gov/biblio/6640930-maintaining-edison-nickel-cadmium-batteriesArticle clearly states that Edison did manufacture these Ni-Cad's in four sizes, 80, 120,160, and 240 a.h.
This is not the whole article but a pointer to the original article.
Still searching more info on this, will keep this forum updated on progress
