My brother I cannot thank you enough my tools put my food on the table when I lost my use of two of my charge packs I was unhappy thinking I got to go drop another 150 dollars to get them but after I stumbled on you're video and did this for myself it saved me a fortune and made my day God bless you for sharing this video man stay blessed

Like this guy. No talking. Straight to the point😆😆

Legend! You will gp down in history as the saviour of all power tools

2.11 for S2 T10 saved me at least 90.00 for a new battery! Thank you and DeWalt must not like you for showing us how to do this!

Used this trick and it worked great! I had a brand new battery that showed it had voltage, but wouldn’t charge. I did what you said to do and it took a full charge. Thanks for the tip!!!

This worked on my dead 5ah battery. The charger would indicate a solid red light as if the battery was fully charged, when it was completely dead. Tried jump starting with no success. This trick brought it back to life. Thank you!!!

I gotta admit, I thought you were yanking our chains but, out of pure desperation I tried it and it actually worked! Awesome dude! Thx!

I followed your directions and just now placed the pack on the charger. The pack is now taking a charge. 😁 It was showing less than 10 volts on a 20-volt pack. Thank you.

This is amazing, thank you! I tried the jumper trick a few times and it never took, figured my 2014 battery was dead and time to get a new one. Did this trick, then did the jumper trick again and now it's on the charger and seems to be working fine again.

Ok, SIR!! Thank you!!! I’ve seen a lot of videos on getting these things to work. None, and I mean none, have worked. Until now. Wow!! Thanks! Loved this. I’ll just say for those still watching this, if you have a bigger ah battery, just remember to do the 2nd deck!!!

Fantastic! I didn't believe it until I tried it! Makes perfect sense though. All batteries need to vent. Now my four dead batteries are good as new!!! 👍🏼

I have to share this video to all my dewalt user friend. I just revived 3 battery. Thanks a lot Respect!

Perfect result. 4 seconds to revive my very expensive Ingersoll Lithium 20v battery. Thanks!!!

Hi Dusty! TomBoy here 🙋🏻‍♀️ Super appreciate this video, it worked on my dead XR 5 AH DeWalt battery!!!

Thank You.... Had two dead DeWalt batteries. Popping the CID brought both of them back to life.

Thanks dude! Worked perfectly! Tried the jumper trick with no success then came across your video and released the gasses out of a couple of the batteries and charged it, and it worked! amazing never heard of this trick before and not sure how it works but it did!

Quick update just got done doing this fix for 2 of my batteries after trying everything else. It worked like a charm. Thank you very much 🙏💯..

I just fix one of my battery thanks to you, It’s Amazing how something so simply can fix the battery

Thank you for this information. I just revived 2, 5 amp 20 volt dewalt batteries. Saved me some serious cash. Thanks again.

Did this, first battery leaked. Luckily I was prepared and expected for the worse - had gloves on and did it over the sink with the exhaust on to mitigate the fumes. I guess i must've punctured it in the process. Had a second battery that also had issues. I was more careful and diligent second time around. It worked (no air release). Just had to do trial and error with the charger to see if it did the trick. Working great though. I'll probably just remove the battery that is leaking from the first one and reolace it. Should be good as new though. Thank-you for sharing!

Thanks for the info about the fuse reset, I learn something new today 8-)

Saved me the price of a new battery thanks for this

Thank you Sir! I just followed your directions and my batteries came back to life. Those batteries had some flatulence!

Nice video. Saved my battery when the jump was not working.

A good video. He takes it carefully and slowly. IM confused now on this -generally-so that no bad thing.

I ordered the security torx. Can't wait. Glad I kept that dead battery in hopes of fixing it.

Dzieki Tobie naprawilem juz 2 baterie od Dewalta

thank you so much for saving my battery.👍

Vous êtes incroyable merci bcp pour cette astuce ❤

Very good video! No telling how many people just think the battery is dead and get rid of it.

It worked!!‼️ Thnx for the upload 🍻

saved my "life" no new battery.Thank you so much

Man this really works had 3 batteries sitting for months ran to the garage and did one just to see. Well let's just say all 3 are good now.

Great video, I fixed my dewalt batery 20v, 4 amp, thank for your help,!!!!!!!!!!!!!!!!!!!!

Good video the Marcel Marceau act was a little annoying, but it eventually got its point across.

Defenetly going to try this next i already did the jump start and nothing i will get back to you soon thanks.

excelente explicación desde Barcelona Venezuela francisco sabino gracias señor

Just saved me $75. Excellent!

No blah blah. but this guy is a great teacher.!

That is brilliant! Nice work.

Thank you!!! Worked like a charm - cheers!

It works. In my case for 18V batteries just a couple of seconds was enough. Used power old cable from 110v desk lamp, no issues.

It worked great,crazy when the air comes out. Thanks, it's crazy what they charge for a dewalt battery.

You are the man!! Is amazing this fix, 10/10 congratulations

Absolutely brilliant, thanks. I do not need it now but the info regarding the barreries am stored. Ta

Thanks for the info I’ll try it on my dead battery

Work , almost through away mi battery’s, thanks 🙏

I left my batteries connected to each other for about 10 minutes. Popped the dead one in the charger and it worked.

1:56 2:23 great. Thank you. It worked for me. connect it with the charged battery for 1 second only. ❤

Excellent. Saved my battery. Battery to battery failed. This worked, though 👍

This is awesome. Worked great, thanks.

This worked, THANK YOU!!

Dude that is awesome ive never seen anyone actually make sense out of these kinds of videos.. almost all other videos on youtube are lies and they dont really work but this video is legit and got 3 of my batterys up and running again..im so glad that i didnt toss them in the garbage because this video was fantastic and now this is something i can always do if i ever have a battery that messes up in the future.. thank you so much for this video you are awesome 👍

Grande hermano ,me ayudaste muchísimo, me funcionó al💯

Thank you very much for this information

Excellent, Great presentation!

Nice job, u must of worked for DeWalt at one time to know that secret.

Thank you!!! Very good video man!

It worked like you said. I had to use a jeweler type screw driver to get it release the air. Charging light came on after 8 puffs of air out of 10. On the charger now with the red light flashing. Thanks. Here's hoping.

Thank you soooo much. Worked great !!!!

I'll keep this in mind next time I have this problem.

Literally the perfect youtube video

Obrigado amigo pelo vídeo, agradeço por compartilhar, estou com problema parecido e com uma bateria extremamente nova, comprei a apenas 2 meses e já é a segunda vez que isso acontece, da primeira vez levei na autorizada e alegaram que não tinha defeito nenhum, nem na bateria e nem no carregador, disseram apenas que foi feito alguns testes, mas amanhã vou seguir passo a passo o seu vídeo para tentar recuperar a minha bateria. Sou de São Paulo - Brasil

Thanks ,it's really working

Thank you very much totally enjoyed your video. Have to admit though, I also enjoy the 😱MG do not do this, nay sayers. 🤯

Sir, I love what I see so subscribed.

Just, Many thanks. it's very helpfull👍

Thank you very much brother .it's work 100 %

The brilliance of this content is unparalleled. A book with similar focus was a personal turning point. "A Life Unplugged: Reclaiming Reality in a Digital Age" by Theodore Blaze

I use a little nylon tool meant for mobile phone screens. Managed to chew 2 using a little flat head but haven't had issue since using this. PPE is a must tho. If you're in a spot you can't afford to lose a battery (no judgement, I am too), your sure as fuck not in a position you can lose your ability to earn. Keep safe, go gentle, measure and test once more than you need and treat with suspicion on 1st charge. When lithium goes tits up, it goes hard.

Id be curious to see what a voltage meter on that was. Ive gotten the charger to accept the battery and charge it to what the charger indicates as a full charge and the pack still only has 10.25 volts. I'll have to give this a shot though. Thanks for sharing

It really helped, thank you

Muito obrigado fiz o primeiro passo de jumper e deu super certo muito obrigado

God bless you it works for me

it works like a treat now i have 3 batterys to use 🎉😂

Very good, thanks.

Gravee salamt boss gumana na Yung battery ko

Thanks! I'd never have found the issue if it wasn't for this video. I had to solder a ground back on, but I'd never have looked and found it had I not taken the pack apart.

It worked! ❤❤❤

Interesting, I will have to see if it applies to my pack.

Thanks brother is charging ❤

You can break the thermal protection on the 18650s. Remember all those batteries exploded years ago? Well on the end of all batteries they put on thermal cut outs (this is that tiny coin looking object on the end, it has a sensor and a chip inside of it, shuts off the charge when it overheats) so you can “short out the charger direct to the battery”this way but you might well cause an explosion later on when the safety thermal switch doesn’t work. I would either replace the batteries inside the unit or just get a new power pack and keep your house from burning down

C’est excellent 👍

Good info!! I take it that if the CID opens, you would see zero volts across the cell? And maybe some small voltage after successful reset? Thanks!

how do u fix a dewalt battery that say fully charged but acts like it almost dead?

Should be pretty much the same for Milwaukee you think?

it worked great..thank you..

Idol ang galing mo

Tried everything then this. IT WORKED thank you ]

Thanks I'll try this..

Your cells are simply almost dead with here undervoltage (no more possible charge again by protection) : no BMS here in the battery for cheaper price, but only in the charger. With your dangerous method (you can destroy the overpressure protection of each cell) you get an upper voltage again : charge works again, but you get only correct voltage at the end , no more amps. You have the illusion that your pack is alive like new, but it will stop very quickly by use. (How many mns for yours? Is your pack correctly balanced? What IR value?) However If you want to do this (useless, your pack is dead) , connect the battery first to a normal 18/20V charger during 1 mn and then place it immediately on the lithium charger : you have the same result with less danger....Here the only good solution is to change the cells with low internal resistance and high amps drain for a drill. (And no cells from a laptop!) But when I see your "precautions" on the video, first of all against possible shorts, I think the best for you is to buy a new one. Sorry but such a video is useless and dangerous.

That something new, will try that.

Good job

Thank you bro

Great sir,

it works thank u so much.....

Thank you! Good!!!!!!!!!!!!!!😊

Pretty good, thank you! Very helpful 👍

Very clear demonstaration thanks

Thenk you its work
