Nimh/nicd ponderings...

[lincpimp]

Ok, so seeing that the mig welder puts out somewhere between 16-30v, and he said to max the voltage. Read somewhere else that a good rule of thumb was double the rated pack voltage, so a single nicd cell would require 3v or so.

Guessing that whipping up a nice high C rated large capacity 1s lithium cell to some heavy gauge wires with some sort of tip to do the pack cells 1 by 1 would work? Or do I need some sort of forced pulse, ala the welder? I have a nice big mig welder, and a few dead packs that I could experiment with.

I understand the basics of what they are doing, with the reverse pulse the effect is to remove the anode material from the cathode. (might have got the 2 terms switched there, been a while since basic physics) So why does he then swap over and recharge it with the welder? I am guessing this is similar to what the "matched and zapped" packs had done to them back in the day of nicds.

I did read elsewhere that doing each cell individually would provide better results, as not all of the cells may be as bad as others...
