I used this method and it worked! My drill came with 2 batteries, one was dead and appeared defective, I measured the voltage and it showed 1.2 volts, I used an external adjustable source and increased the current and adjusted the voltage to 19 volts, then of the procedure I measured the voltage and bingo! 5.3 volts. I installed the battery back into the charger and it worked!! thanks a lot!!
Worked like a charm.. I used a car battery and gator clips. Clamped negative to the 9 oclock position and slow tapped the 3 oclock and 6 oclock positions.. Then clamped 12 oclock and tapped 3 and 6 oclock positions again.. Tried tapping them fast and it didn't work.. Slow taps worked everytime.. Ordered 2 new batteries and just fixed my 4 old ones. Thank you!
Making use of the ---> batery.repair reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type
I followed his steps and I was able to revive 4 batteries. I've noticed that if I use a battery and completely run them dry, they will not charge back. So I went ahead and followed these steps and all four came back on. Thank you very much!
Just tried it on a old battery i had laying around.. was going to throw away the whole set because it would never charge. Just tried this technique... and WOW !!! It actually worked !!!! Going to leave it on the charge since its actually charging now and see what happens. Thank you for the neat trick. Very much appreciated
i used a 12 volt car battery charger with a 2 amp setting (and safety glasses!!) with the leads attached to screwdrivers. first battery worked great first time through. second battery i had to repeat the entire process 4 times, and it worked as well. Thanks for the video!!
BRO! Thanks for listing this alternative! Worked for me too! Unligged 8 times quick and then on the 9th plug-in, took the battery out and back in and now it's charging!
Pretty cool, I tried it and it worked! Before doing this I took apart the battery and noticed a thermal fuse and little diode looking bit.. This must reset those in some fashion. No it doesn't fix a bad cell, which can only be replaced. I'll be taking new voltage readings in each bank once the charge is complete. Thanks!
I used a car battery charger, 10 amp - 12volt with a visual amp indicator dial because I didnt have a good battery. I have 5 "defective" batteries so I experimented on the posts. What I discovered is that it worked using only the two opposite posts. + being the one he noted in the curved section, at the bottom in his video and - being the one at the top in his video, or the biggest section with the flat side. As I hit the posts, my car chargers amp meter spiked a couple times, when it quit spiking I stopped. Volt meter tested 8 to 11 volts on all 5 batteries. First one just came off the charger after green light. Ta-da, works!
Hell yes man! You just saved me big! THANK YOU. I bought a craftsman set at a garage sale for 10 bucks cause the batteries were dead. If you're skeptical try it.. This crazy shit worked. 12 volt marine battery tapped each 10 times.
Best method worked on a battery that’s been sitting for 4 years and was having a same issue saying defective battery but I did the same thing as you said but with my car battery instead lol the battery works now and is charging
It works best if you use a higher voltage than the battery you are working on, I use my mig welder, it puts out twenty something volts, I went over ten years not having to buy batteries for my Dewalt stuff because I used to dig the batteries out of the recycle bin at home depot and zap them, I would always leave one for the one I took.
Did anyone notice that he put one jumper on negative (left terminal) then hit positive (right terminal) then went to the top terminal. That terminal is the 2nd negative. Then he put negative clip on top terminal (2nd negative terminal) then hit the right terminal (positive) then the bottom (positive). The 2nd part he did it correctly,but the first time he went negative to positive then negative to negative. I'm a bit leary as to the success of this.
Yes. I noticed. At 1:34 LMAO! whoops! Youll notice as he did the second + he went to the first - and paused for a second and realized what he did wrong the first time but kept going.
I'm amazed this works, but it does. Just tried with my oooooold batteries. Too early to say yet if they hold enough charge to be useful long term, but at least I can charge them now. Seems to drive the drill and impact driver fine, but no go in the recip saw. (Although the recip saw drained brand new batteries in like 10 minutes of use)
I tried this trick on another battery too but it took 5 tries and finally the charging electronics in the battery allowed it to charge. Make sure you do have current and amps going through your leads. good luck !
this actually works! i didn't do it 8 times... needed to leave it on for 10 seconds... before the trick the voltage was 3.5v, then i found a laptop charger with 19v 3.5A and did this and it brought the battery to 19v! then i put it back on the regular charger and it worked like magic! not sure how long it will last but at least it revived it!!
I've read about battery reconditioners but can't seem to find them. The closest I've come is that iMAX Lipo B6 unit which both charges and discharges a battery. One TH-cam video shows the change in battery capacity after cycling the battery through something like ten cycles. Quite impressive. I just noticed that the original iMAX Lipo charger doesn't do anything but Lipo batteries but the V(ersion)2 and probably the V3 do all sorts of lead/acid, NiCd and other types of batteries.
he was not tapping the positive terminal the first time after moving the clip to the top one.he said the positives were at 3 and 6 o'clock yet he was tapping the top or 12 o'clock terminal which would be negative. At least that's how I see him doing it!
If I understand this correctly, you don't need to know which terminals go together. Just attach to jumper one at a time to a terminal and tap all three other terminals. The ones that are 'wrong' won't matter; negative & negative, positive & positive, positive & negative of different circuits all will have no effect; no harm, no foul.
An original Craftsman 19.2vdc battery, part# 1301341, only has 2 negative and 1 positive on the battery. On top of the battery is marked as 1 positive and 1 negative. The 19.2vdc Craftsman charger has 1 positive and 2 negative terminals. I remember I bought it in the early '70s or the mid-80s. I'm leaning towards the '70s. Not only that, but I also purchased a Craftsman 13.2vdc drill about 2 years before the 19.2vdc drill. That battery still works a little bit and quickly loses the charge within 1 1/2 days. I need to recondition that one soon. I will try this technique and then post the results. Likewise, I checked the current prices on the internet, which only has 3rd party new batteries. The price range is $60 to $140 for the 19.2vdc.
I'm glad it worked but @1:33 you tapped the top negative/12 o'clock. Shouldn't you have tapped the 6 o'clock position instead? If I understand this correctly, the idea is to clamp to the negative terminal, then tap the positives, then clamp to the other negative and tap the positives again? So it should look like this: Clamp to 9 o'clock and tap 3 and 6 o'clock positions. Clamp to 12 o'clock and tap 3 and 6 o'clock positions again. Is that right?
CyberGolem : you are most probably correct. under the stress of videotaping I may have hit the wrong terminal, but you get the idea... the goal is to share the method, not necessarily to duplicate each of my moves...
Amigo me sientas no entiendo el inglés, pero tengo 2 baterías muertas y estoy buscando como repararlas, me explicas como le hago por favor, te paso mi WhatsApp 311-122-72-30 o mi correo ivan_fibba@hotmail.com Saludos
@@jawdiel usa un cargador de baterías.. el esta haciéndolo a 19.2v q tiene la batería. Tenes 2 negativos y 2 positivos.... simplemente conectas como el muestra ahiii solo q OJO el invirtió los colores... en realidad el negro es el negativo y el rojo el positivo... conectas el negativo y le das 8 tokes en los bornes positivos con el lado positivo.
Hey i dont see the other end of the leads. you said it is an old charger which i i think i see to the left, but i only see a cord running under the newer charger. so where do the leads come from. i am laymen, where is the source of power here?
Hrroach, like I said in the video, I used a (car) battery charger (12V) to which I extended each lead with a smaller one I could use to make contact on the craftsman battery. (The cR battery charger leads are too thick)
I did this, and my battery shows 7V and 11V across the sets of terminals. When I put it in the charger, the defective battery light which used to be on before is no longer on. But the charger still says "fully charged." What could be wrong?
I tried this on all 3 of my Craftsman 19.2v batteries. Didn't work for any of them. 2 still say defective and the other never lights up anything. Also the 2 "defective" ones didn't spark at all going across from 3 to 6. I guess these all have dead cells. Can I make 1 good one from 2? Are the cells removable?
@Tony : sorry to hear your batteries are dead. This procedure is only useful if the batteries drop below a certain voltage and become dormant. By applying a higher voltage, their voltage goes past a threshold and your charger then recognizes them again send is able to charge them again like before. If they become defective however, you will need to replace the individual cells.
Yes, that is also confusing, but if you watch carefully you can see in fact both charger leads are red, so I guess we just have to take his word on the polarity of the charger clamps.
THIS VIDEO IS A FRAUD!!!!. He claims to have fixed the dead batteries,but the guy didn't use the correct procedure to restore them. Then he claimed they were fixed. I might believe he could fix them if he followed the correct procedure,but the fact that he didn't makes this video untrue & it should be pulled.
You know in the video you touched positive 8 times then negative 8 times first. Then moved the negative clip over to the other negative which you just said was positive and…So you should redo your video or correct yourself ASAP.
This does not jumpstart the battery. in fact, the only two terminals that are connected to the battery are the ones at the back 'flat' side (this is the negative terminal) and the rounded part (the positive terminal). The other two lugs are just for temperature sensors, so they did nothing... You may have in fact blown them out. I'm not sure, but they are sensors and not active devices...
Alexander Borsi, ____ Actually not. On a Lithium Ion Craftsman Battery that would be correct, only the front & rear terminals are connected to the battery source. On Nickel Cadmium (the older Craftsman batteries) however, all four terminals are connected. 2 to negative and 2 to positive.

Pull it in snd out of charger real quick. You will notice after it says its charged. Just do it again and it will fully charge.
Thank you. It worked like a dream

+Chris Bennett I noticed the same thing
Yup.. I was like WTF?!
Sure didn't make sense to me
Caught that shit too.
Caught that shit too.
Does anyone know do you have to show a charge on both positive and negative sets of terminals? how many volts before it should take a charge ?
I just took it on and off the charger 8 times and it worked

I'll be damned, it works. Thanks
so the green light blinking means it's charging? if so would solid green mean it's full?
Can it work with A 18v boosting a 19.2 battery?
Done. It worked! I conected the drill battery to my car battery for 10 seconds. What is your experience with the battery life after this procedure?
had to do it twice it worked for me ,i used a car battery charger
I'm glad it worked but @1:33 you tapped the top negative/12 o'clock. Shouldn't you have tapped the 6 o'clock position instead?
If I understand this correctly, the idea is to clamp to the negative terminal, then tap the positives, then clamp to the other negative and tap the positives again? So it should look like this:

No worries and no hate, just wanted to make sure I understood it. Thanks for posting.
But in your video, your procedure worked, so you must have done it right? If you had used the wrong terminal, it would not have worked, right?
Hi good info, But which wire i have to use for to jump start the battery?
Just place 9v battery on pos and neg terminals for 30 seconds problem fixed. Charge your battery. no wires or meters.
I don't know how others who copied this procedure got batteries to work. They mabye got 1/2 of the battery charged back up,but not the whole thing.
Me funcionó a la perfección
