You said the first time you’ll do reverse polarity. But you did it straight polarity.

Just wonderin, were you stoned when you made this video??

would taking the battery pack apart and determining which individual battery cell is not charging (using the multimeter) and zapping that particular cell only be better or your method would improve all the batteries together

will this work using a stick welder, and just to make sure. You said for 18V Dewalt battery to turn power to 110amp range? first you shock using the correct polarity and then you switch to reverse polarity, then you juice it up again the correct way. Right?

I reversed the voltage and then charge the batt with the welder. The meter showed a increase in voltage but when I went to use it, there was no power. Do I need to put it in the regular charger and if so for how long?

You can also use a car battery charger, if the charger has a jump start option like most of them do now days. Set it on 50 amp leave twice as long as the video was showing (since he was using 90 amp). I also used car battery charger for my 3.6 black & decker versapak batteries. Use the 10 amp setting on car battery charger for these.

What exactly makes the battery explode? It seems like if you hold it on too long or the battery gets to hot, it will explode fairly easily.

Great info-Only on my regular lincoln wire feed welder, the clamp is positive and the wire electrode is negative. This tip worked great once I stopped doing it bass ackwards-duh!

@dewalt23293 thanks for your perfect answer
I would like to ask to give shock to every batterys how mach should be our source voltage and AMP for that !
thanks

@TheVidsbids2012 . i have had that happen to, basically you have a partially fried cell that wont take very much power. so you can try it again or the battery might be beyond help. any more questions feel free to ask

@TheLordClem a dremel battery is do-able, but i would use a car charger with a start feature that puts a bunch of amps out, or you could use a car battery. as far as the + or -. i too have a similar dremel and if you look on the bottom of the tool it only uses two contacts so if you find out which ones they are on the battery you can then determine with a meter which is which, any more questions feel free to ask

@mega5531 not a good idea because most likely the battery is a lithium battery which will explode if you try it. but something you can do is put it in a deep freeze over night & then put it back into the laptop and let it charge. this should fix it. any more questions feel free to ask

Hi Dear
thanks for your clip that was excellent , I have dead laptop battery , and I have no supplier machine as you .
Can I use my car battery as main source to give shock to the battery?
thanks in advance
