    Don't beat me up on this! It's just for testing! Finding 20 tiny metric bolts in the shop was a pain in the a$$. So, I wired 10 of these up for a quick test, not great. They were at 0 volts as they were new in box, so I did a 2 amp slow charge for about 4 hours. They came up to 13.9 no problem but didn't handle a load at all. I let them sit over night after another hour of charging and will charge again today in hopes they do better tonight, I'm not thinking they will. So I guess I'm sitting on a whole bunch of expensive p.o.s.'s lol. Least they were free!

    I'm NOT a flooded NiCD person, but I think they can be restored if they have issues; I would guess  you found info on line but here are a few links;

    yes they can be restored...  I will have to dig out the manual I have somewhere on the CPU and send it to you, in the mean time go to the SAFT web site and look up the SPH battery type that was the closest I could locate.  there are some down loads there that will give you background info on NiCds...  you will need a better than average charger btw...

    the wet nicads are nearly un-killable, but toxic (because of the cadmium)  and there will be many interconnects needed (either in parallel or series)
