hairyone Posted April 29, 2009 Share Posted April 29, 2009 The 12v nicad packs for my combo drill have been neglected / knackered for some time. Won't charge and only giving about 4.5V. Was going to buy replacements and came across this on the net, and found this Revive Nicad batteries by zapping with a welder. With a little trepidation I tried it out, and .... it works. Tried one pack first, now back up to 13.4 volts and now charging and holding a charge. Did the other pack today. Apparently it can also be done with a car battery or a charged up capacitor, just need to zap a way the filaments that are shorting some of the cells. Very pleased £80 saved Quote Link to comment Share on other sites More sharing options...
