I salvaged some Ni Cad batteries from a crane magnet fail safe system.
The batteries are 30 ah 1.2volt cells, they are strapped and bussed 5 together
which makes 6 volts. I tried to charge the batteries and they do not seem to take a charge.Does any one know how to determine if they are serviceable or scrap. My goal is to use them as additional storage in a cycle charge system that I presently operate at a remote cabin.
Thanks for any response Doug
