mickyd, I use the Ryobi 18V ONE+ system because I got tired of trying to keep up with three or four different charging systems and battery types. I also got tired of having one or two chargers even with the ONE+ system. So, this Christmas I bought myself a present that will keep all 6 (4 ni-cad 2 l...

I found this a while back, when this discussion first arose. I don't know how technically reliable it is but I am certain it rises above my level of expertise. At any rate, I zapped just the bad cells because the others were up around 1.2 - 1.3 volts. I chose to zap only the .000 volt cells. The pa...

3 bad cells! Maybe more(longer discharge will tell that tale). Should I just put it in the drill and let it run until it no longer rotates? I haven't seen it mentioned here but the original instructions for this that I saw said to put the battery through a full recharge cycle before zapping it. Was...

The initial verdict is in!! The reconditioning method used above WASN'T effective BUT.....that just means plan B is needed, just don't know what plan B is right now. When I put the reconditioned battery pack in the circular saw and tried making a cut, the battery pack discharges from 20V to about 16...

Looking at the individual cells , flat end is negative, protruding end is positive. . [ATTACH]11288[/ATTACH] . . Number each of the cells so that you can keep track of which ones you've done then connect an alligator clip lead to the metal conductor that connects the battery to it's neighbor. Black...

Reconditioning tired Ryobi 18v Ni-Cd battery
The topic of reconditioning Ni-Cd batteries by 'zapping' them isn't new. It was discussed in this thread . I have 3 Ryobi's that are shot and at $30 a pop new, I decided to first try the 'zap' method vs. buying new. My newest battery was just over a year old and when fully charged, wouldn't last but...
