3 years later and this still working. Thanks for the tip my friend!!!!
Great to hear!
You are genius 👍I can't believe I bought milwaukee battery 6 months ago I tried to charge it gave me broken flashing light I did exactly what you said and now it's working thank you so much 👍🙏
Thanks so much! Best tip I've found on UA-cam that saved me from having to buy four new batteries. The fifth had enough of a charge to recharge, and then I used that with the scissors to give the other four a starter charge to fully charge them. Great job!
Glad it helped!
Thank you ! I have 5 batteries that were dead and now working 😊
Thanks mate. this is youtube knowledge at it's finest
Absolutely brilliant! This totally worked for me. Thank you so much.
This absolutely works. I used a wire from terminal to terminal instead of scissors, but this definitely works.
This method worked fine for me with a 12V Li-Ion 2Ah Bosch battery, which seems to have good capacity after being revived and charged. It got overheated several times during charging after the initial boost presented in this video. I left it to cool down, and then resumed normal charging until full.
The battery was dead right from the start after unpacking the new drill, I am glad I kept it around until I saw this video, thank you!
I suspect that this method is very useful to get a battery out of a deeply discharged state, where the charger will not start doing it's job. What I mean is that it's not going to make wonders with a battery that has reduced capacity / dead cells after a lot of use.

Worked perfectly for me. I had lost one battery pack in my attic 2 years ago and recently found it in my blown insulation above. I used small electrical jumpers for about a minute and then charged it all the way through. Thanks for the advice. Beats $133 for a battery at Home Depot!
Fantastic tip! Thank you! Worked perfectly!
Did the battery drill for a few years and got sick of the lack of power + the cost for another battery! For a number of years now I'm happy using a extension cord which never loses power... + I don't have to keep buying expensive batteries that have to be recycled once it can't be recharged. The battery drill is great if the electricity is unavailable.
Built a house with a Porter Cable 14V. Switched to Ryobi. For non-professional but serious home use - the 18V Li Ryobi family rocks.
As for yard tools, I think Ego is fine. I had American Lawnmower/Zombi 58V. Not going back to cords and gas.
CJ, don't forget the power you get from as you put it, extension cord. Even brand new battery fully charged won't match the power of corded tools.
You can also do a similar method to your car battery that goes dead. You need to have a charger that is rated for at least 200 amps. There's a UA-cam video on it
Try dragging an extension cord around a job site.

Thank you for the knowledge.....regardless of all the haters, it dont hurt to attempt to revive and definitely easy enough to TRY.....
Thank you so much, I managed to charge my late father drill, thanks for the tips
Dude, just did it. Works like a champ.👍 thanks bra
I won't be able to try this out today, but I certainly will before long. I noticed a number of positive comments, and I had seen this done with wire in another video so I know there is something to it. Ignore the haters...there always have to be some Negative Nellies. Thanks!!❤
Great tip..better than some of the complicated ones I've seen. I've got two sets of scissors, just not one charged battery to jump it off of :( 3 uncharged drills, including one Makita not from a power pack 🤪
ThanX for that. Just want to mention that my hand drill charger packed up so I now use the car battery charger. Both take 12 volts and it works every time saves buying a new expensive replacement drill charger. Twelve months later still using the car charger and the car charger still charges my car battery so no problem. Just locate the positive terminal on your hand drill battery.
Do u use 1 dead bat and 1 charged battery
Thank you! That worked for me too? Had Dewalt Lithium ion batteries. One of them wouldn't even register on the charger? Two min scissor technique with my other battery worked!
Handy, timely info!
Very helpful! Thanks!
I've just had this problem, didn't have 2 sets of sisors so just used two bits of wie, and it worked , cheers
Your video is most easy and efficient, it worked, Thank you.
Glad it helped
Great video! Thx for the info.
good idea never thought of it. thumbs up
I’ll give that a go. Beats spending money unnecessarily, thank you
I had several dead batteries, instead of this, remove the battery packs out of the cases, use a ohmmeter to see which doesn’t have any voltage (check after having on charger) and replace that cell from one of the other ones, most packs only have one dead cell keeping the battery from charging full. Just need a soldering iron. I’ve made 3 chargeable batteries saving $$$ until I run out of replacements.

You have saved me a fortune! We have 20+ drills 3 corded and 1 working battery charged. Thanks!!!
@@violahernandez6446 7
O
I’ll try that next time. Thanks. Good advice
Excellent!!! Thanks a lot.
Thanks for your time and the knowledge you delivered on this video.
Awesome trick! Rejuvenated my old Dewalt that was in the recycle bin.
I have a question I bought a battery operated chainsaw Harbor Freight in for some stupid reason I opted to just get one battery at the time they now have discontinued this chainsaw and I can't find the battery anywhere online so my question is does it have to be the same type of battery to use to do this or can I use another battery let's say a DeWalt battery and try to charge this battery with it? I still have the charger to for the battery of speaking of which I could continue to charge the battery with after trying this technique
thanks for your tip friend,good advice
Worked! Thanks.
awesome and I'm able to fix two of my batteries...Thanks bro
THIS is a good video in that it shows it is possible to get a little more life out of the pack.However there is a video out where the guy explained JUST because the drill spins DOES NOT mean the battery is GOOD. I thought why the hell not.HE SHOWED WHY.!!! you need to put the drill under a LOAD,TRY drilling a 1/2 hole in wood with pressure.IT may stop dead let off the pressure it runs.He explained it this way.IT takes 18 volts to spin the motor but very little amperage.THE AMPS the battery can keep putting out are what has the POWER.To do it right you really need to replace the cells that no longer have CAPACITY to hold amps.Hope this helps you guys that are like me and like to mess around getting stuff to work again for fun.
Yeah, internal resistance is another factor in batteries dying, anything from an old AAA zinc-carbon to a car battery. In flashlight batteries, over time gas bubbles build up around one terminal and that obviously limits the output current, I suspect something similar happens in nicads but I'm just guessing. It's independent from the reversible nickel crystal short circuits that can be zapped as seen in the video, but as the battery ages both processes occur.
Thanks just discovered your video today. I have several batteries in my garage that seem dead . I plan to try connecting with between batteries with jump wires with alligator clips
Worked great, saved me from buying a new battery
What about the newer dealt batter iui es that don't have that long stick up part?
Thank you so much - just lost a battery over the weekend and was about to buy another... will try this method.
Did it work?
@@oilhauler76 no - but I'm trying it with a different style battery - 40v more rectangular... has 4 metal connectors and after the initial attempt I've been super busy and haven't had a chance to play with it. Using Ryobi battery... any suggestions?
@@wwhite181 let me know please sir
Thanks man, you just saved me a 60$👍
Great tip it works thanks👏👏👏
You are a gd genius Gump...They are gonna make you a general.
Thanks I have four batteries .I'm excited 😁
Once the cells are shot, the charge won’t last. I like the d cell replace/solder option another person suggested. Pretty cool permanent solution.
Thanks, that worked. at first i tried it with shinny Radio Shack jumper alligator leads they got worm right aw ay. Used the visors works like a charm.
I have done that on Craftsman C3 Lithium Ion Batteries several times. It may have 1 cell go totally dead, the charger will call it defective and won't charge anymore. Pop the top off after taking out 4 or 5 screws, jump the pack to a good one to supply voltage than jump the dead cell with power if needed, once it goes back positive for a few minutes get it in the charger asap. It will charge up normally and work for years again with no issues.
The first thing this old Guitar Doctor (Stars Guitars in San Francisco "Back in the day") thought of was to replace the pair of scissors with 4 alligator clips, one at each end of two jumper wires.
Yep!
A bit safer!!
The wires heat up too quickly. Use scissors instead, they won't heat up. Do your own video if you think you can do better.
@@stefanmeyers2808 I can do better.What he is doing is a total temporary fix on dead batteries that won't hold a charge but a few minutes.Been there.Done that.Buy new tools,especially if they are DeWalt.
@@larrynew7258 If a person doesn't need or can't afford new tools, then your way would be more expensive. He has helped me, you haven't. If you've bin there done that, then why have you come back to watch it again? You remind me of my dog that likes to return to it's vomit.
Wow, that's a great video. I will always cheer for you in Korea I'm looking forward to a great video. Have a nice day.
So cool, can't wait to show my sister.
I can't believe it, but it worked out for me, thank you
I'd like to do this with my dewalt 18v battery that isn't working, but I only have 1. Can I use a different batter from a different drill?
you should be able to or use a car battery
It worked, thanks!
Thanks 👍😊 buddy 😗☺️ Have a good day
Thanks much. Subscribed
I fixed my dewalt batteries by buying Milwaukee tools. No comparison!
Good answer,...I did similar thing but with Makita Lithium battery powered tools!
good one you got me rolling....
Lithium ion batteries have much more energy than Nicads. My lads said "Dad, don't muck around with Lipolys, they're much too dangerous. Nicads & Nickle metal hydroxides are only batts I "fry whiskers off" using an higher voltage for a "flash". Funny that Paul; my friend gave me his deWalt Post battery Nicad blackbox set ($1500 yrs ago) & bought Milwaukee/ No comparison he says. Hence sons & I are deWalt users. Amazing tools. My dad had an alloy Black&Dekker skill saw, handsaws & built 2houses in his short 49yrs. Fred NZ
Dude dewalt batteries are way better than the Chinese Milwaukee batteries
👍I know that's rite
You are awesome thank you
Never in the manual so many thanks.....
Wow thx great tip
Thanks for sharing, never knew you could do that, can't wait to try it on my batteries now 👍🏻
did it work
Did it work ?
Did it work?
@@chaosband I did it on the Ryobi battery and it worked .. I was amazed .. how long it lasts I don’t know .. I just did it over the last weekend
Thank you! Worked for me!
Glad it helped!
20v and 18v are actually the same number of 3.7v Li-Ion cells, some companies are advertising full charge and others use base voltage.
Dear Mr Haykus, Glad Frank Lee corrected your guess of Lithium Ion cells. Our lads say Never touch li-ion cells as they are extremely dangerous. Nicad & NiMH (Nickel Cadmium, Nickel Metal Hydroxide) are the only batteries one can "flash" (touch/apply higher voltage) to burn off the whiskers that grow between & short out the poles (+&-). Faithfully Fred Hughes
batteries range from 1.5-1.8 volts. 15×1.6= 18v 15×1.8 makes 20v. a drill battery is 15 rechargeable c batteries. dont know where youre getting 3.7 volts per battery. 15×3.7 is 48 volts.
My batteries will charge they just don't last long. I'm old school and hate battery devices so I bought a Honda 2200 generator for the back of my truck. My "battery" weighs about 50 pounds, fits every tool I own with more than enough power, and never needs charging. It even fits the house if the power goes out. That's what I call a battery!
FYI if you have a smaller generator that you use frequently it will start when you need it. I have a large generator that seldom gets started that may require work. Better to have a small one that starts than a large one that's sketchy.
What would 'car' jumping a dead battery do that an outright charging wouldn't fix, does the 'smart' charger circuitry stop the current flow when it reads a threshold lower voltage on the battery?
Hello
Can I use 18 v new battery to revive a 14.4 v dead battery for my cordless drill?
14.4 v new batteries are very hard to find these days.
Can a trickle charger be used? I have two dead battery packs so I don’t know if this method will work
A similar situation for car batteries. Connect the dead battery in Parallel ( + to +)(- to -) and put the Charger on @ 2 amps. Seems the Current FLOW helps the Dead battery come back to some sort of life again.
I've just watched you video on rebooting a dwalt drill battery
I've got a karcher backpack hoover but when I put the 36v battery on the charger it goes on the green for about two seconds and then starts flashing red.
I've left on charge overnight but it doesn't seem to charge.
Is there a way of doing this procedure I've only got the one battery
Thanks Brian
Need to know where is the dip stick for Tran on a2007 Toyota tundra need to add oil
Thanks Man..will do
I have 2 14.4V dead batteries on Porter C drill. I have the charger but no other 14.4V battery. Could I use a Milwaukee 12 V bat that is fully charged?
I have never tried it with 2 different voltages of batteries. I would think it would still give it some juice as you only need to give it enough juice for the charger to grab on to but I don't want you to ruin your Milwaukee battery by listening to me lol. Try at your own risk and good luck.
Thanks brother, that was awesome! Like giving it a jump!
Lithium cell balancing. What happens is the Lithium curve. If you dump more then 80% of the charge they drop off in voltage sharply. Chargers are designed to detect a certain voltage then begin the charge state. If you burn Lithium down past 20% remaining it cycles it 1 time. If you do this too often you'll change the chemistry. So cell balancing like he did brings the voltage back up where the charger can detect it and begin to charge it. NEVER leave a lithium cell dead for to long. They will self discharge slowly in a non rechargeable dead state and thus the charger will refuse to charge them until that low voltage is met.
@@TheWickerShireProject those are not Li cells, they are NiCad. Look at the charger when he has the battery in it, it very clearly says "1-HOUR NiCd Charger"
The good battery powered the drill faster than the recharged ones. You could hear the difference. Pressing the trigger is no real test of the rejuvenated battery's readiness to tackle jobs. Instead, drive a screw with it to see whether it does the job or poops out.
or a cordless circular saw
Yes you can hear the recharged batterys are not full charged and are slowly dying, sorry but ones its dead, its dead
Used alligator clips and did just great

thanks great idea
The charger says very clearly Nicad, meaning its not based on lithium ion. You can safely put a 12V car battery to force charge it.
Just because you see a spark at initial (flat 18V Lithium Ion battery to 13.8V fully charged vehicle battery) connection, does NOT mean the current is flowing in the desired direction. {Using a 1N5408 in series could help solve this}
A 24V truck battery is closer to the desired 21.6V charging voltage required for the 18V rechargeable drill battery. ✔
Say that you have two like you have and one from a Snap-On one that is good now how do you tell which is which one and how are you connecting them ?.
This works on packs with all good cells with little loss to original power rating but it seems that you have a bad cell in the bunch, hence the lack of power.
One can repair the pack IF they have the proper skill and knowledge. But as dangerous as these cells are if over heated or ruptured, it can be extremely dangerous and catastrophic to life and limb and should NOT be attempted. .
I saw a friend throw a screwdriver on his work bench and then a hissing sound. He knicked the tip of a battery cell from inside the pack that had gone bad and the next thing we knew the cell flew up off the bench emitting a 3 foot flame that was no joke and proceeded to fly around the garage for what seemed an eternity but in reality was 7 seconds as per cctv footage.
If this doesnt work when you try this hack, dispose of the pack properly, PLEASE!!!
These things are like bombs if one goes off, they all go.
Cool vid bro! Knowledge is power.
I took one of my old batteries and opened it up.... ran a 4" double wire with a plug on the outside drilled a little hole in the top to push the wires through and hooked positive and negative to it......then took a longer wire with a cigarette lighter plug on one end the plug on the other to attach to the battery. Plug it into any 12 volt source and it works just fine.....
I'm the American version of Red/Green
had a friend do the same with an old ingersol ran a wire from it with alligator clips and used it to work on trucks.14.4 ingersol running on 12 volts has enough to pull valve covers off on a Mack using the trucks batteries.
@@timmyhipbird7543 Drove and repaired plenty of mack trucks over the years.... still have the scar on my ring finger from being too lazy to disconnect the batteries when pulling a starter..... wrench in hand touched the frame thru my ring
@@notwrkn2mch needed a mentor to guide you you don't wear rings the obvious being electrical and the other getting in and out of truck and ring caught on something and you loose a finger.plus it is just in the way.don't reach in socket to pull out nut while still on air wrench.allways use safty glasses,and place stands under everything jacked up.I watch the Pakistain videos they are accidents about to hapen.I'm retired now with over 40 years working on trucks and have all my fingers and toes some scars from my younger years but nothing major.
@@timmyhipbird7543 30 years and retired.....My buddy lost his ring finger jumping out of a Transtar... I do all the safety stuff but was very young and made a very stupid move
Kind of defeats the "cordless" feature of the drill. But, in a pinch you have a working drill.
These lithium batteries can Jump start your truck too, just wire some Romex to wedge into the proper channel/terminal of battery and touch the Romex to correct pos/neg term
I have a Lincoln elect grease gun that the batteries won't charge on unsure if it's the batteries or the charger thanks for the tips on here I may try a car battery chargers
Good idea, did this to fix 14.4v i got a deal on.
Thank you sir
Can U use a fresh 18v to revive a dying 14v battery ?
Good idea. I have two dead batteries and two new ones. Will take your advice and try to resurrect the two "dead" ones. Like you, my question is how long will the charge last? Thank you.
I just tried it on my Ozito , was looking good, said fully charged but lasted about 1 minute then back to square one. Reckon they must be able to be renovated so will keep looking. Gonna ring or email Ozito and see if a dead battery can be resurrected see what they have to say
I tried several different methods of "reviving" batteries. Listen to me...forget this crap. Save yourself hours of frustration and just go buy yourself a new battery pack and be done with it. Or not. But when you're done screwing around with this, don't be embarrassed to come back here and acknowledge your mistake. You're in good company.
This is good advice if you can find another battery like the one that is no good anymore. I bought a battery-operated chainsaw and I only bought one battery now the chainsaw has been discontinued at Harbor Freight and know where online can I find another battery so now my chainsaw is no good unless I buy another chainsaw
you have to reboot the bms and that will fix it sometimes>not always
put life back into a 12 volt car battry with a 12 volt lipo4 battery and it is fine.saved me $150 bucks.

That's great thank you
That is all fine and well but what about us guys that have t4wo dead batteries? I was thinking I would take one of then out in the garage and using wires or alligator clips and hook it up to my car 12 volt battery for a minute or so. Is this feasible or am I going to have the lithium battery blow up if I put the juice to the wrong pole? It's a craftsman 13.2 battery with 4 poles to a battery.
I have not tried a car battery before but heard it works. I would not try it on the battery currently in your car just in case. Should only need a small jump to give it life.
the stem on that battery sure is clean and new looking for a battery that will not hold a charge any longer, just saying that there should be some scruff marks or something from inserting it into the drill.
Gives a whole new meaning to the term "scissoring"..
Suggestion: If you turn the phone horizontally before pressing "record" you'll get more in & the video will be easier to watch. Wide-screen instead of keyhole.
Yeah isn't technology great!
I agree. I'm tired of turning my monitor up on end to watch videos like this.
You'd think smart phone manufacturers would disable recording in portrait mode. Very annoying when watching a news clip on TV and the video cuts off the left and right 2/3's of the screen.
Yes, all the different types of advice, most do not work. I have removed the battery pack and connected it to a 12V, 7,5amp motorcycle battery by means of a 3m cord. I do woodwork and need to drill, countersink and screw - so I have my new drill for drilling and 2 others connected to the battery and they do the job well.
Pretty clever. Seems a bit ungainly... but you now have a 'corded' drill. Nice work.
Can we use li ion mobile batteries for drill battery pack?????
I've turned this video into a drinking game for my friends. You have to drink Everytime you hear the word "SO" you'll be hammered by the end!
Good after that test your batteries with your tongue 😂🤣
SO ?
LOL 😅😅
After you revived the battery and then used it till it died again, was you able to plug it straight in to the charger and continue using it as normal? Ive Read a few comments now and it looks like for some people it has been a case of having the use a reviving method over and over.
Try not to let it get 100% dead or you will have to do it again.
Also when you leave the battery on the tool it dies completely so once you use it unplug it from the tool and charge again.
I had Batteries R Us replace the batteries in my 12 and 18-volt drills
for about 45 dollars each
Might be more now after several years.
I did the same thing, but then the battery that they worked on lasted only nine months and then would not take a charge again! I don't think it was worth what they charged!
@Lonnie Chartrand no because you could have bought 4 of the Chinese knock offs for yellow or red for about 100
Very good video. I think the same thing happened to my BlackBerry PlayBook. For some reason it is not charging because I haven't used it for like 2 or 3 years. The only reason I picked it up was to get the photos and since it is probably glued shut I think I'll give up on it until I watch a UA-cam video that tells me how to open it and take care of that battery.
I have 2Dewalt 20volts batt. The other way to fix that problem is to open the case and replace all the 1.2 volts that are soldered together inside that adds up to 20v. A bit more work but last much longer, it’s a matter of choice but it’ also an option. Still you got a good trick.
Getting the battery up enough to charge is one thing, but the battery holding the charge is quite another. My 18V batteries charged up, but the next day they were dead again. Still needed to replace them.
I use an ATI Radeon cooler to fully discharge it, after the drill stops working. I already experienced improvement. Charging time is 5h fir all cheap devices.
