Here is a replacement battery if needed amzn.to/3voqOCJ
anyideas on getting a 20v 6.0amp an hr battery to charge it has some life but wont full charge
I just did this to 3 dead Dewalt batteries, and it freaking worked!!!!!! Thank you so much.
I am glad that it worked for you. Please share the video on your social networks
Lithium batteries are not designed to be used beyond a low threshold of power, usually nothing less than 40% or so, and in most cases the internal circuit board is the charging monitor and it is designed to shut off at a specific point to not allow a lower level of discharge. If a battery sits long enough it will self discharge below this level. Jumping the dead battery charges the capacitor on the monitoring circuit, allowing it to believe it has the lower limit and it adjusts to allow charging. I use an 18 GA wire with a bent loop at the end to plug into contacts lie this in order to not spread the contacts too far. This is a good video, Thank you for posting.
I have a ryobi battery. How do I make that work

I have a Craftsman 19.2 battery. I bought a charger for it. But I have no way to jump-started except off my Dewalt batteries. What should I do and how do I do it
Thanks, friend. I ruined my Ryobi 18v model P102 by leaving it in charger but in my frozen garage over winter, now dead. Don't have a mate to jump start but do have a B&D 18v p pack. Worth a shot with this method?
Thanks for this video. I have a Dewalt battery that was “dead”. I followed your step by step video and viola…my battery is charging again. Saved me a lot of $$$
Awesome Mate!!! I just bought a bunch of new De Walt batteries just in case my old ones start to give up, but that is really vital info if ever i am out in the middle of nowhere and don't have a good spare with me for some reason. It's the kind of''know - how'' that can make the difference making or losing money on a job or getting oneself outta the crap. Thanks Man.
No way..they say you learn something new every day..Thankyou so much for sharing that with us..Have an awesome day & Take care,xx
Wow. Just tried this on my small lithium flashlight batteries and it also worked. Thank you.
tried it . . . it WORKED!!!!!!!! The DeWalt 20V would not turn on the charger, but after I followed the directions in this video, it charged and charged fully!! This video is worth its weight in gold.
IMPORTANT SAFETY REMINDER @RICHIE ...THANKS
So.... That worked like a charm!! I watched the clip earlier, gave you the like before I tried it I was that confident. Worked so well I had to return and comment. So for all those who've done this and it worked, Thank you!
ABSOLUTELY happy to like your video. Thanks so much for sharing this. Wiring the batteries in parallel is a great tip to transfer just enough power to trick the charger. I had an old mobile phone battery that would not do anything and after putting it on and off the charger many times with zero life I put it in one last time and then it initiated the charger and charged and it's been fine ever since. But you're video jogged my memory so I can't wait to try your idea on my DeWalt 18 volt batteries that are lifeless through lack of use. I love my cordless tools but whenever you need a tool without fail it's always the Old Faithful corded tool that never fails. Cheers again.
I just tried this and it WORKS! Saved me a lot of money!
Thank you from the UK, something i had never thought of, had two dead 1.5 mah B and D batteries, jump started from a 2.5 mah Power Exchange without issue, saved me buying yet another drill.
We followed your instructions with the wires. Thank You it worked. Wouldn't have known this if we hadn't seen your video
.
Worked perfectly with my Craftsman 20v! Thank you for this great hack/fix!
I like it it looks simple enough. I will try it towards the end of the day when I gather up all my dead batteries thank you for the tip and will let you know how it works out. Have a blessed day.❤
Literally the most useful TH-cam video ever!!! Thank you sir!
Been and done it mate works brilliantly , good on you for sharing it 😊
Best hack I've seen here for months. Kudos for you💙
I already tossed bad ones a month ago and watched your video today. Thanks for sharing.
THANK YOU SOOOOO MUCH!
Had two new Black & Decker batteries that had been left too long without use and the charger would just flash red errors and do nothing.
This worked INSTANTLY! They're now charging green!
Straight up worked. Used 20v DeWalt to awaken 20v Bosch for about 3 seconds. Charger blinking now! Ty.
Brilliant top tip mate bought a multi tool with only one battery a few year ago used once when I got it back out it wouldn't charge your tip is spot on works on any multi tool battery now its charging after 3 year 👍 cheers mate
U the man I'm sitting in home depot and about to go buy new batteries and it worked u just saved me a good bit of money thank God for TH-cam
Thank for that great tip. I was skeptical when I saw the title, glad I gave it a chance. I use these exact tools and batteries daily in my work and this is a common problem.
This revived my 14v DeWalt battery. Thank you.
Good to hear it worked.
What a brilliant tip !! I had a battery that I thought was dead and had put it to one side for when we went to a battery collection place. I saw this tip and gave it a go.....WOW !! Just gave it a one second jump and tried it in the charger and hey presto, battery now charging. Thank you so much for sharing this with us.
Question: How good is your batteries now? I mean after your success, is it still working good now? I just threw away one death Makita battery two weeks ago. If I watched this video before, I tried to do it like you. Thanks
I probably threw away a Craftsman drill battery that could of been saved a few years ago. I know now. Thank you.
@@VidTubeWatchprobably saved yourself from a ion fire and burned down the house.
They are designed to stop working for a very good reason.
Kaboom!
Hi does this work on batt that no longer fully charges ie 2 out of 3 light s when charged
Also a one off , can it charge of f another same size batt
Thx Joe
@joebalkovics3322 It does work. It's really for a battery that won't charge at all. Try to jump off with a good battery of the same kind. Just follow the directions in the video. If the battery is totally shot or dead, then probably not. A battery that will not fully charge as you described is on its way out.
Just repaired all my dewalt 12v max. Thank you so much!
Excellent video! Today TH-cam suggested I watch your video and I am so glad I did. I will try your trick the next time a battery does not charge. This may save me from spending $120 or so on a 18V 4Ah rechargeable battery. TX SO MUCH!!
Thank you! It’s crazy how much $$ these new batteries are! This happened to me years ago before I had seen this trick, and ended up buying a whole new tool bc it was just as much as buying new batteries!
Worked for my 18 volt lithium. Went from 2.3v measured to full charge 18v. Held the wires for about 15 seconds. Thank you!
That's excellent! Thanks! I'll keep that in mind for future if they ever go completely flat
You just saved me $20. Thanks Dude. Only took a few seconds on my 20V lithium. Liked....
Oi vay...... thats how to do business today..... pull this comment down, dont let the goyim know how to save money !!!!!!
So easy when you are shown how!....brilliant!...👍🏻
You are a genius; was just about to toss the drill. Saved me money. worked like a charm !!!
I bought a Hart drill combo and the battery that came with it NEVER worked.......well...... until I watched your video and used your technique. Flawless!! Thank you, sir
I’ve just done what he showed me and it’s worked. Not used the battery for nearly 2 years as I thought it was totally gone. It’s now charging. Thankyou very much.
Pls report back on how much work can the revived battery do. I try to store lithium batteries around 20-30% full but sometimes they bleed out their juice before the next top-up.
Same here mate 3 years and charging fully
You will have to rejump them quite soon
just remember that this will charge, but your capacity is crippled unless you replace the dead cell that caused it not to charge in the first place.
Thank you Flannel, I will give it a try. You are a good man!
thank you for watching
Thank you,
I bought a set and one battery never would charge, it’s been a few years.
Your trick worked like a champ, thought I had nothing to lose.
I’m back with 2 batteries working great.
Most useful tip on you tube thus far thank you sir salud!!
Thank you very much from the UK, I was skeptical about the battery fix but I had a second battery that has never worked in over four years. Did your wire trip to spare battery charged and now fully functioning. Many thanks.
My friend came round today with his Bergman 18v 'dead' battery,-he couldn't get a new one anywhere,-so we tried your trick today using my Bosch 18v battery. It worked a treat,-so thanks a lot for this video!
I've got a Ridgid that was brand new, left it.on my radio and it hasn't worked since... this didn't work for me, any ideas?
one of the best videos on youtube! Thanks Mister!
Worked like a charm on a cheap Chinese 21v battery for a handheld saw. Arrived from amazon seemingly dead. Saw a few little sparks when connecting the last negative wire. Thought that might have caused a problem, but it didn't. Thing charged right up and works perfectly now. Thanks a lot.
I had the same few sparks then charged up to fully functioning spare battery
Worked like a charm appreciate it
Thanks much for the tip! I have a "Ridgid" and a Ryobi drill. I'm gonna give it a try and see if I can re-use them.
I tried this snd have successfully revived 3 of my 20 volt DeWalt batteries. It really works. Thanks gir showing hiw easy it is to bring dead barteries back to life.
This is really helpful. Thanks a lot.
THANK YOU SO MUCH!
I have 2 brand new never used 20v (newer style) porter cable batteries I let sit for 2 years. Dead. I Took my 18v (older style) RYOBI 18V and it worked! Both were lithium. I held it for about 5-10 seconds and that's it. It works!
glad it worked. please share this video
I have a old black & decker how do I do that one with one battery
@@eulessjohnson-ku8hoborrow your friends, or someone in another comment even got a 12v car battery to jump it just enough
Brilliant thankyou very much. I had a pile of dead camera batteries and after watching this video applied the same principle, jumping a good battery to a dead one with two paperclips and the so-called dead battery charged immediately. The holes to poke the wires in were tiny in a 1 x 2 inch camera battery, so I just flattened the ends of the paper clips with a hammer and it fitted perfectly. A very happy viewer, Phil UK.
Thanks for this - helped me fix a batteyr which had been dormant for 9 months. Also I used this hack for a laptop battery for a laptop that had been in storage for the last five years. Cheers!!😀
Worked like a champ. Can use pennies in the slots and then use clipped wire leads. Thx!!
Good idea
Note he's letting a lot of current flow to the flat battery. There's no resistor in the circuit. This could damage a battery or maybe make the wires hot depending on what you use. Just do it for a second or two, don't walk away.
X2 and I sure as heck would be keeping those in a steel box for storage after that. When they see how much a single AA lithium battery can light up from overcharging, or force charging a bad cell......it changes a person....lol
Tried it on one battery I've had at work that has been dead for a couple of years now just sat in a corner of my box forgotten. Did the trick and it's charging. AWESOME THANKS 👍
OMG you are incredible. My battery was dead. And after what you said about wires. Now is charging it. Thanks again
That's an outstanding trick! Wish I had know this years ago before I tossed all my older batteries.
thank you for watching. please share the video
Me too thank you
Anything that mitigates waste in my book is a good thing and you're a star.
Thank you for the tip… I’ll try it. I have a dead 12v one. God bless you
Hi there I have just tried it on my Milwaukee batteries and it works great i had 4 of them that way going to throw them away. thank you 👍👍👍👍
An incredibly useful tip. My son returned a totally exhausted Bosch hedge trimmer. I was about to toss the dead battery but tried this hack. It worked beautifully and has saved me at least £60. Thankyou!
This is a great idea provided you Have 2 batteries and one is in good condition! Usually my situation is the battery will indicate charged, but only last a few minutes.
thanks for watching
Such a useful and informative tip, these batteries are seriously expensive and it worked for me first time.
This is what TH-cam really should be used for
Just looked at your video a few minutes ago and with all the concerns I had in mind about a possible fire I took my two batteries outside to do it. Like magic it really works. Thanks! You saved me a bundle. I live in the Caribbean ordering a lithium battery online means shipping to Miami first and then paying air freight to my island then pay customs. A forty dollar battery means $108 in my currency (East Caribbean Dollar). Shipping it is about $35 in our money then customs on a good day will charge 40% around $57 for the importation costing me around EC200. Thank goodness I found this video and thank heavens you shared the info. Thanks again.
Thank you for this. I had a 20v max DeWalt battery that has been non responsive for over 6 months now. I followed your steps and 'boom', back to life. I'm glad I didn't discard it!
Very cool! One thing: you said "toss them in the garbage" these batteries need to be recycled - not thrown in the trash.
Your video does defenitely make sense! Output from the fresh lithium battery is about 21V. Will try it today!
it worked. you are the men!!
Very useful! Thank you for sharing this. I have a bunch of DeWalt tools and will most likely need this at some point.
😢🎉
Fan-TASTIC video. Who would believe that it's so simple to fix? The explanation makes perfect sense - without even the tiny amount of charge needed to send signal to charger that all's O.K. to recharge - it wont!
This must save so many people (including myself) so much time and money. Many thanks for posting.
thanks for watching. Please share the video!
You misunderstood this, the charger is specifically designed to refuse charging a fully depleted pack, not even with a tiny current. A lithium Ion cell might be internally damaged if it is fully depleted in such a way that once it's fully charged agan (no matter how slowly) it can get internally shorted and bust into flames. Even a small cellphone battery might be enough to burn your house down. Some years ago I also thought I was very smart when doing this. I might still do it if I have to, it will work, but I would discard it as soon as possible after in a safe way.
@xehpuk Are u saying they're resistant to recharging in the first place because they are internally damaged?
@@rchristi761 It will charge for sure but it shouldn't be. In worst case a damaged li-ion cell might ignite fire.
@@xehpuk 🙏
Just saw your video,so I ran downstairs into my garage and I tried your trick? HAPPY TO SAY IT WORKS!!! I left the spare battery charging right now. Thank you for this great video you saved me money and you know this batteries are not cheep, so thank you very much!! I’m subscribing and like your video
glad it worked for you. please share the video
I wasn't even searching for this issue but it appeared in my feed for some reason. And shortly after, I found a battery that wasn't charging. I had my doubts, but figured what the hell. Lo and behold, it worked!
I won't lie, the spark and slight burning smell when I connected the last contact scared me, but it saved one of my precious DeWalt 20V batteries, so thank you!
Yep, it worked for me 👍thanks :)
Holy cow ! This is a great tip. It would have been nice to have known this a couple of years ago before I retired. No telling how many good batteries I tossed and bought new to replace them. I worked my tools hard, so I just figured I pushed them too much.
This works well on NiCD and Lithium-Ion tool batteries. Not quite so much on a deep discharged lead-acid battery.
Thank you very much. Used to fix a Bosch power for all 12v Lithium battery.
Taking the rest of the day off!
Holy smokes, where did you learn to do that? This will definitely be helpful for me, thank you so much.
thanks for watching
This was a great tip! I was about to through a $100 battery away that I had left a charger attached to. The battery has been dead for a year or so at least, until today. Thanks!
Top tip, it loads again, many thanks from the Netherlands
Thank you dude. worked with my m18v Milwaukee batterys....
Turns out I needed to charge my Milwaukee M12 a bit more to get over the safety limit for the charger to engage. 8 minutes seems to have done the trick. Thank you!
Great tip that worked perfectly! Saved me the cost of a very expensive drone battery! Thank you!
Glad it helped....now you can help me by sharing this video on Facebook
What about E-Bike battery'$ ?@@flannelguydiy6458
Thanks mate it worked a treat. You have now got a new subscriber. Take it easy.
I wish I would have seen this earlier. I might have gotten rid of a good battery. Thanks for the info!
looks like a simple fix and I will try it
Thank you for this video! I have 40v Ryobi tools and one of the batteries suddenly would not take a charge. I decided to try your method, but checked voltage first. The 'dead' one was showing less than 2v. When I jumped a good battery to the dead one, I got a spark when connecting the negative terminal, but only once. I checked the voltage again and that battery was almost up to 40 volts. I put it in the charger and it immediately started charging. Saved me $100+ for a genuine Ryobi replacement ($60+ for a knockoff).
knockoffs ? or refurbished?
Hopefully he will explain how to recharge a Panasonic battery please
Glad to see this comment. I have a 40v kobalt I want to try this on. Per another comment I’m waiting till I have one of my other 40v batteries to be at about half charge since fully charged ones may not work for the jump.
I was told that putting a dead battery in the freezer overnight is another way to rejuvenate it. Has anyone tried this or have a comment?
Hey, I had the exact same battery that you recharged, and it worked like a charm. Battery would not come alive with no light in the charger, just like yours. After your B+, B - wire trick, charger light started blinking and Batt was fully charged in one and half hrs. Thanks a bunch!!!!!!
thanks! it works for my milwaukee m18 battery pack
Wow..this was pretty awesome and was great to learn this technique as I have a Ryobi drill and you know how expensive these canbe I also told my hubby about this and you thing I hung up the moon using said drill ...So thanks for the new status in the world of tools and women ...lol am going to subscribe to you so hope to see some more vids that wow me, thanks for the tip though am going to share this with my friends if they need it and share your site with them too 👍👍
Tracy thanks for watching. Please share the video so others can see.
I do have this going with one of mine for 6 months. Glad I didn't throw it away. I'll give it a try today! Thanks
Worked perfectly, thank you!
It worked! I had it on the hazardous waste bin for two years!
The same problem happens with normal 12 car battery chargers, they have to see a certain voltage coming back from the battery to check polarity before starting a charge cycle, it is also a part of the 'anti-spark' and short circuit proofing that if you connect the clips together the charger will not pass any power. Sometimes to charge a battery you need to connect a 'good' battery in parallel to start the charge and after 10 minutes take the good battery away and the charger will happily carry on.
Did you just explain how to jump start a vehicle
@@jygb7092 Only if you belong to a certain group of people....
WOW, THANK YOU!!! I was about to throw my drill and buy a new one, thanks for sharing your video....
Saves a TON of money on buying new batteries! Thanks!
*The way you make your tools is amazing. I really like the way you do it my friend* 👍👌
Thanks for the heads up, I appreciate it. I'm gonna try it out this weekend.
Great tip. I haven't used this on power tool batteries, but similarly I've found that on car batteries, the newer chargers with all the sensors can have the same problem with very low batteries. So have yourself an older style car battery charger that will push charge Into it. Then you can use any charger after that.
Or just connect another car battery same voltage to it, leave for a few minutes and disconnect
@@adrinathegreat3095 because you usually got stuck buying the digital "smart charger" because of the lack of options for old-school mechanical dials
I have used this technique for 8v golf cart batteries. I boosted each battery with a 12v charger for a few minutes, then wired the batteries (6) in series for a total of 48V. The charger for the golf cart is "smart" and needs to see a minimum voltage to start charging. Thank you for providing this method for tool batteries, I would have never thought to do this.
6 that’s a ton of money for golf cart batteries
This is brilliant, just tried it and it works! Have emailed all my friends with batteries..thanks. 4:49
Yeah, it helped! I was about to throw away what I thought was a dead battery. I tried this first, and it worked. Battery is charging now as I type. Now, to see how long this formerly 'dead' batter lasts on this charge. Thanks Flannel Guy!
It worked great - I found it worked easier if you flatten the ends of the wire before inserting
into the battery terminal
Great idea! So simple… But effective
