If you have a lithium battery that is dead and will no longer charge, don't despair, in this video I demonstrate a last ditch method of how to revive the battery. The hack that I will share with you in this video is just like jumpstarting a car but instead we are using it on a power tool battery. I also include a few simple tips to make the process safe and simple. Check it out and thank me later :)

![RYOBI 18V Battery Not Working? [Easy DIY Charging Hack]](http://i.ytimg.com/vi/sqeiOkSNRsU/mqdefault.jpg)
56 years old and still learning smething new everyday and this was by far one of the best lessons yet
Worked great. I only left it for about 30 seconds and tested it and was already good. Thanks!
This short video is perfect to explain its not a simple task to just buy batteries and "get more" out of our electric equipment. Thanks for explaining this to us.
Well said!
Outstanding!! So much easier than other videos, I saved well over $100 using this video to save 5 dead, unchargable batteries!! Thank u sir!!!!
And I have 18v ryobi
Worked like a charm. Thank you. Got a Black and Decker for Christmas that wouldn't charge out the box. Did this with a fully charged Worx battery and now it's charging. 🤘🏾
I am a homeowner with a day job who does not do anything construction related for a living. That being said I am working on framing out my basement and Bought this czcams.com/users/postUgkxHQsUrwNr5GQrnx9V4xDdUr56qxwuiBHt gun. I have done a few walls already, have probably shot a couple hundred nails through this thing and have yet to have a misfire. It works awesome, good depth on every nail if you have your compressor set right. My literal only complaint is that it is a bit heavy and my arm can get a little tired especially whrn I am nailing at odd angles. That being said I am super happy with it and would buy it again. Hoping the old girl allows me to get my whole basement finished out!
I searched different videos but yours was the one that I felt I could follow best. It worked for me, saved me from buying a new battery and not sending it to the dump or to hopefully get recycled. Great video and great instructions, to follow at your own risk, love it!! Thanks!!!
You're welcome!
Heard of this quite some time ago and didn't believe it, at least not fully but to my surprise it worked. Also great step by step guide. I'm not well enough informed to recommend this to others but it's a start, thanks a lot.
happy to help
This rocks! I had a Craftsman battery that I never could charge. After putting on a small charge for like 30 secs, it started right up on the charger. So cool, thanks!
Great - make sure you sub
Thanks for the wire hammering idea . Saves me muck'n about with croc. clips and bits of metal . Perth , Western Australia .
No way man, this is fantastic. I have a real need for this! Thanks you so much!
Glad I could help!
61 year old professional tech here, you just saved my old battery packs, many thanks. Always learning!
hey mate - make sure to sub
Dude, this was simple and to the point. I'm amazed at all the high quality stuff ur putting out these days. Beautiful!
Thanks mate - time to bring back some batteries from the dead
Your video just saved my batteries. It does work. Thanks!!!
Thank you for this! I just attempted this and it worked with my 2 Milwaukees, had one at 20v and the other I couldn't even get a reading or at least a volt. Connected them for about 30 seconds and the 2nd reading jumped around 12 to 15v, the dead one then took the charge.
Just saved two dewalts and one Worx, you are the man. Thank you!
cool - throw me a sub
Thanks for confirming what our thought process had in mind-just used this on a Motorola Impress battery, 20 second jump start and now on the charger.
Awesome - make sure you give me a like and sub
Worked for me!
Left the battery uncharged in the basement for 5 months, couldn't charge it anymore. Connected a spare battery to it for less than 30 seconds, tried charging, and everything works!
Thanks!
Worked like a charm just like he said it would I can’t believe it. The only issue is you must have the same battery luckily I had one. Excellent! Works again.
Thanks mate - make sure you sub
If you notice once you hook up to test the battery the second time (after the jump) its steadily dropping in voltage...... The battery has a bad cell in it. Ive jumped several different types and size batteries in the last few years, and over time, I've discovered that no matter the type or size, if it has a bad cell, (or cells) it will continue to drain. Thus that battery will continue to drain over time faster than a battery that doesn't have a bad cell. There are ways to replace individual cells but that is not as easy for just anyone to do. Excellent vid though, and hope that info helps.
Can I jump a 12v onto the dead 20v
@@scottschmittmusic thats what I'm wondering, he says at 1:50 "the voltage matters", but I was thinking as long as its the same type of battery it should work, and I'm just making what I thought was a somewhat educated guess. LOL
@scottschmittmusic No you need at least the same voltage (but also not too much higher) less will not charge it. Although if you put two 12V batteries in series, then you'd be in business.
Have a blessed day!
Thank you so much for such a clear and helpful video! Just "jump started" one of my Milwaukee m12 CP 3.0 batteries that wouldn't charge but would still start a tool, just showed low battery. Was registering a little less than 10 V, 80 seconds later, showing 10.8 V, showed two bars on a power tool, and plugged it into the charger and it started charging as it is supposed to. Again, thank you so much! Saved me buying another battery or a $73 service few to Milwaukee since it's outside the warranty range!
glad to help - please throw me a like and sub
Thank you so much for the tutorial. I saw some other video and used a simple steel wire and it just burned out !!
I had totally missed out on the Amp and Wattage understanding. It took a a $1 for a feet of 14 gauge wire and 30 seconds to charge my dead battery. You saved me exactly 99$
Great - throw me a sub
I like the way you just hammered the wire flat, I pissed around looking at Stanley knife blade's and picture hook's till I found four matching slim hook's
Yeah - it is a simple little hack
I cut both ends off some jumper cables and it worked perfectly thank you so much. I bought a tool set and I thought the batteries were bad. And now they're charging dude you are so awesome
Excellent!
the trick is working.Very usefull! Thanks!
Wow! Totally works. I saved a Dewalt battery and a Black and Decker battery with this method. Thanks. Saved me a bunch $
Thanks mate - throw me a sub
Thank you for a very easy, clear to understand, video.
Thanks for the video, just saved three batteries 👍
Dang this worked. I straight touched the wires from a good battery to the dead - literary touched it for 3 seconds and Wam- worked immediately. Thank you!
Thanks for the sub
It worked. Thank you so much for this video.
Great to hear!
Great, useful video. Clear and concise.
Glad it was helpful!
Thanx, sceptical but I tried it , hot dang! It worked!
Thanks for saving me $180+ on my Lowes Kobalt 5amp battery! I really appricaite it 😊
your welcome - throw me a sub
Thank you so much. Nice& simple. Direct& to the point
Happy to help
Thank you, I'm gonna give this a shot
I have 4 black and decker batteries I've had for over 20 years, 2 of them I have "rebooted" multiple times and they still work as backups. They tend to release their power faster than my new ones but they are there when i need them.
I like the solid wire trick. I use an auto spade connector with a test lead
but those connectors are SO small I am always loosing them. I'll try yours.
!
I Did mines with 14 gauge wire I got from my neighbor and its worked. I did just as he said 5 min and place it on charger, it's charging back up. Thank you.
AWESOME - love to rescue good batteries
I came across with your post and thank you very much..if you're near here I'm going to treat for a beer. I followed your instruction and My new battery worked!!!! Thank a lot sir!!. God bless!!
Who knew! Great share. 💯💯💯
*Andrew, you are making me drunk too much. Every time you say, "Guys" I take a drink, and by the end of your video, I'm wasted! It's a throwaway word, much like when kids say, "like" three times in each sentence. It comes across as if you are trying to hold our attention. You're so good, we're not going anywhere! Thanks. 👍
like thanks guy ;)
Great tips. Thank you.
Glad it was helpful!
Simple ,big helps thanks
You're welcome!
great info i need to try that on several my old defunct batteries
Go for it!
Great video it really helped me out thanks
Glad it helped
Awesome vid sir thxu!!
Awesome hack!!!! Actually works
It worked for me.. Thanks!
Kite army I have an old model dewault drill the batteries doesn’t work is there a replacement that can fit to work ???
Thank you
I worked for me.
You got a new subscriber. I will tell everyone.
Thanks for the sub
I just did it on my 18v 3/8" impact wrench battery and it started to work as he said. Great thanks alot. Don't have to buy a charger or battery.
I will like to say thank you
I have seen videos on this subject in the past this only reason for me to be looking for this and seeing you is I found a hart tool on the side of a road must have fallen off someone's truck I had this tool about 3 years now yep it be dead
Then my Milwaukee tool died after 15 years so in the interest of saving a few Lincolns I got a charger and that problem well I did do it pretty close only difference was I used a 19 Guage wire the thing I noted was the battery did get hot the other thing was it needed to cool a few minutes then it wanted to work well need mention I did try once while it was hot and nothing till after it cooled now it is holding a charge I figured I have nothing to lose I found it
And you talked me in to it with a fine video brother
Otherwise it would be still a paper weight
Then that other thing you mentioned was Milwaukee is apparent company indeed that's nice all although it don't handle like the Milwaukee free is the price no complaint
Good job done
Super, thanks heaps! I had no luck with an 6Ah 18V (20V US) battery starting up a 9Ah 54V (60V US) battery but when I used a battery with the same voltage as you suggested then it worked! Whoohooo! I was nervous using my expensive battery to do it but it was a winner! Thanks again.
I actually got ripped off on Facebook Marketplace after being sold a battery cheap and then getting home and it not charging and the bloke blocking me so I could not follow up! I felt pretty dumb but turns out I got 54V 9Ah battery for $90 Australian dollars. Whoohooo! Did I say thank you!!!!
I'm going to try this!
I wish I had another identical battery to fix my 24v but like you said, you need another 24v to do this. Thanks for the tip
Do you have two 12 volt batteries by chance? You can wire those two 12 volt batteries in series and then charge your 24 volt with those.
Great video
Wow bro it worked, you saved me a lot of $$$
Nice
Works like a charm!
Sure does
Going to gthe this a try. Thanks so much.
Did it work?
GGreat video, I have 2 bauer 20v batteries I'm going to try this with.
Can you use any battery to jump another battery?? Or do they have to be the same??
Like the energy and subscribed
Thanks mate
worked great thank you!!!!
thanks - throw me a sub
Any other kind of wiring that we can use? Not sure I have some spare household wire lying around
I have a Worx 24 volt battery that went dead. However, I do not have another 24 volt battery. I do have a 40 volt Black & Decker (higher) or an 18 volt Performax.
But from what you sre saying, I MUST HAVE the same voltage? So I would either need another 24 volt good battery or I am SOL. Is that correct?
What could happen that is a bad outcome if I tried using either the 40 volt or 18 volt to attempt the jump start the 24 volt? Just curious.
Thanks a lot for this video!
Checked 2 Mensela 2 Ah and 2 6 Ah (50 USD each). One showed 4 lights, the other a poor shadow of one LED, and it took no charge. Kicking, jump starting, the poor battery a few minutes, like You did, and it takes charging! Wow!
No surprise. Opening the sad battery quite some electronics sits inside.
If the voltage goes down too much the built in controller doesn't run and then no charging is performed.
Unfortunately the battery only charge up to 13 volt, not 18 - 20, and is scrap.
It just works!!! 🥰🤙
Great - make sure to slap me a thumbs
Omg I have like 6 batteries that won’t charge after watching this video im going to try this method great video
Good luck!
Also you're able to do that the cheaper battery packs where you jumpstart them most high-end battery packs like Milwaukee have protection boards that won't allow this but the cheaper packs without protection boards you can
I did it and it worked tx a lot
sure - could you throw me a sub and a like - TX
❤ Thank you!
I fixed a dead battery I found from the dump for my ryobi tools works perfect
nice - now sub
thank you and on a flashlight li-ion round batt
Thank you for saving me 💰
YES - love it
Thanks man !
You bet!
What if I don't have a spare battery? Can I run the + and - terminals to the charger directly?
I noticed mine has 4 terminals, but only 2 are + and -??
Can you do that with laptop battery? or phone battery? by end of life they used to be get a bit swollen
Cool video
Thanks mate - glad you liked
I've got 3 porter cable batteries that all simultaneously decided they'd charge for 30 seconds and then be complete. So I thought it was the charger. Replaced the charger. They'll charge for an hour now but then say complete. However you connect em to a tool, they are all dead.
Porter cable also discontinued. So I don't know if they need a jumpstart or if I should just use knockoffs from now on
It's crazy I did that to jump start my truck years ago with my Ryobi 18v battery
Why does the voltage have to be the same on the jump start battery? Wouldn't a more voltage battery equate to a better jump start? I used an 18v/54v dewalt jump start battery for my 10.8V dead lawn mower battery. It didn't work. I got the lawn mower battery to one signal light charged but that wasnt enough to get the charger to fully charge it. And I dont have a multimeter to test how many volts it is. Where am I suppose to find another 10.8V battery?
Thank You…🙌👍
I've got a cordless lawnmower battery that shows fully charged but wont power the mower for more than a few seconds....It's not the mower as a friend tried my battery in their same mower and had the same problem with my battery....any tips please?
So for how long we should connect the cable between the battery in order to jumpstart it ?
I’m going to try this on my ego 5.0 hopefully it works🤞🏽
I have heard rumors that it might work
Keep us updated bc my 7.5 stopped charging.
Was this work with the Ryobi?
I have a Craftsman V60 battery. How do I identify which is postive and negative?
I have a dewalt 20volt 5amp that when put on a fast or slow charger it shows it charged. When u take it off it is dead. The charge lights don't light up at all. Tried doing the jumping it then lights up. Left it on for 5 10 15 mins didn't matter still said it was charged when I hook it to the charger? Any suggestions
Would that work with a halo bolt??
I have done this on car batteries and a lawnmower battery where the smart charger isn't smart enough to charge a completely dead battery, and 1.5[1.2]volt rechargeable AA batteries.
It hasn't failed yet.
Cool - have you ever tried this on a battery
It is worth opening the battery pack [ I presume it is out of warranty, because doing this will void it]. The thing to do is to check each cell to see if the voltage on all are more of less the same. One or more cells on a lower voltage means those cells are toast, so this method will not work. If you are good with a soldiering iron you can de-solder the trashed one[s], replace them, and try again. [At your own risk, blah blah blah].
If you start a fire with a lithium battery, they are really hard to put out, even with the proper class of fire extinguisher, so there's that. If a Lithium battery gets too hot you will have a "thermal runaway" which is super bad news. The smoke emitted can be highly toxic. Some cells contain lead, nickel, cadmium, mercury, and electric car batteries, cobalt. If you breathe cobalt for example, you are dead. So if you are anywhere near such a fire, go upwind and away. FAST.
Probably why such hacks are not recommended.
What would happen if I used a 24v Kobalt battery to charge a 40v Hart battery?
So what happened to the robbed battery? Did you ruin it and will it charge and be recognized by the charger?
You sir yes you sir you saved my life thank you
Thank you - pls sub
Thanks for the info. I just did this process on a 36V battery using a 40V battery and it's now Charging.
how did it go?
I have been trying this on my 48v lawn mower battery. When I plug the last of the 4 connections in (be that +ve or -ve), it gives a spark and small explosion - any idea why that is? Anyway, by Jove it worked. Saved £160 for a new battery!
WOW 😳 thanks 👍
You're welcome 😊
Just worked for me, dead one has green light on the charger anyway.
Had to buy another $70 battery to do it, but now I have 2. It'll be nice not to have to swap from drill to drive.
Cool - make sure you throw me a like
Unfortunately while the jumped battery appeared to be charging, after the green charger light went out, the battery was still dead as doornail.
Certainly worth a try though.@@Kitearmy
Does the donor/working battery need to be the same capacity/output as the battery to be repaired? I have an M18 8-amp battery that needs fixin' but the only other M18 batteries I have for jump starting are 5.0xc
it might work
Saw your video. Excited! Can’t wait to try it! Have a Ryobi 18v one+ battery that just endlessly flashes red on the charger.
Did it work?
@@Kitearmy yes it did! Thank you 🙏
Tried on my Canadian tire impact 14.4 volt wrench and it worked. 14.4 v batteries are not made anymore.
Thanks
did it work
what do you do if both your drill batteries are dead?.
