I was also curious about these "reconditioning" techniques for sale. I could not find any credible support for "zapping" of NiCd cells. I did, however find this 2001 article that had support from the US military
and decided to try out :
Read about the differences between "exercising" and "reconditioning".
I tried the reconditioning recommended on several NiCd cells showing barely ANY voltage. I took a good 1.2v cell and jumped the weak one to over 1v. I then hooked a tiny light bulb up to the weak cell and very slowly let the cell go down to .6v as recommended (the bulb was almost not even glowing). The discharge took several hours. Then, did another recharge of the weak cell up to 1.2v. I ended doing this same treatment to 8 (almost dead) cells to rebuild my Makita 9.6v stick pack. My Makita charger now recognizes the stick pack and will charge it as normal. After a few exercising cycles (after doing the cell-by-cell reconditioning), the stick is now THE STRONGEST I have. I did side-by-side tests with this reconditioned stick pack in my driver drill, screwing and unscrewing in a whole box of 3 1/2" wood screws.
This procedure is FREE, and is utterly amazing! This really works and I was very pleased.
