Are they Ni-cad or could they be Ni-Fe (nickel iron) 

My understanding is that the Edison cells are nickel iron, but I could be
wrong.

 

Ni-cad's are very toxic, and a disposal problem.

ni-fe is based on a alkaline (lye) electrolyte and easy to render harmless.

Hello Wrenches,

A friend was given some old Nicads (ED 160s).  These are single cell
batteries that are roughly 16" tall, but much smaller than an L-16 in the
other dimensions.  After being used for an unknown amount of time, they were
stored in a barn for 10 years with no maintenance.  

If these were lead acid batteries, they would clearly be scrap.  Is there
any chance that these could be any good?  If so, what steps should be taken
to get them out of mothballs?  

Thanks,

Drake
