Revive Nicad Batteries by Zapping with a Welder

Step 4Zap the Hell Out of the Frickin' Battery!!

Zap the Hell Out of the Frickin\
The title says it all.
Tap the positive end of your welder to the "plus" terminal of your battery
while holding the negative end to the battery's "minus" terminal.

You should see some sparks and nothing should get welded to anything.
No welding please. If you get killed by a poisonous explosion it means you did something wrong.
It should feel like something good is happening.

this trick only works on nicads. Trying it on other types probably won't work

Hey There, I believe this can be done with any battery that has lost power after a charge. They seem dead.... They are not. Try using a short peice of wire to touch the positive terminal to the negative terminal causing a spark. 2 sparks may do the trick. If not it sounds like you need to get a power source that is double your battery voltage and "ZAP" the battery back to life! Positive to positive and negative to negative. Brief touches of both contacts at the same time shock crystals that build up in the batteries internal lead and acid. SO you will wear "smart clothes and eye protection". Good Luck.

Maybe a tenth of a second per shot. Give it three shots, then test. It's better to test and end early than risk frying the cells.
