Kolb people,
Recently there was a discussion on rejuvenating our older gutless NiCad power tool batteries.
Someone suggested a welder, but advised to be very careful. Knowing me, I'd rather not find myself
blown into the next county, so I opt not to try the welder method. Besides.....I'm a little low on acetylene,
anyway. (that's a joke!)
I've got two 18 volt DeWalt drill batteries that are so weak, that even after a full charge, I'm about to drive over them
with my tractor (not really)!! Usually at this point, I send them off to have them rebuilt. But, this time, I've put it off until
now I'm lucky to get them to work for 10 minutes after being on the charger for a full day.
So, after our recent discussion on rejuvenating them, I thought I'd see what an internet search would pull up.
I came up with this Youtube video, and am about to go zap them!

I have three 12volt scooter batteries (from a recent project), all charged up and wired in series. In the meantime, I've been
draining the life out of the DeWalt 18 volts. Now, I'm finally ready to give this guy's method a try. I'm headed out to my
shop to zap them right now.
After I've zapped them, and charged them as much as they'll take a charge, I'll report back with the results.

(I noticed some difficulty getting the Youtube link to display the video. If you have problems watching it,
I'll copy and paste it again, hopefully with better results)
