Resurecting NiCad batteries

[lockedup5]

I was looking on ebay and a guy had a manual on how to recharge bad NiCad (dewalt) batteries by jumpstarting them for $6.95 I think. Just wondering if anyone here has done that and if so what did you do and how did it work? one thing I found said to zap the terminals w/ a welder. Kinda wondering cause I have like ten bad batteries and would be nice to use them.

dont know how to zap them but i have used a company called prime cell. they take and split the case on the battery and put in new cells most of the time upping the ma/hr rating on them significantly. and it costs roughly half the price of a new battery.

here is a link to thier site if you want to look it over http://www.primecell.com/

couldn't you do the same thing with battery cells you buy at a hobby shop? I used to build my own batteries when I raced r/c cars.

For the record, I just buy a new tool when I need batteries. They come with 2 new ones and a tool for a little more!
