You sir, are the man! Fixed my issue. Had not used my battery since 2013 (currently 2021) and your trick brought the battery right back to life & is charging as I type this! Thank you!
Thank you very much. I had experienced this problem with two previous batteries, and was about to call DeWalt AGAIN, when I found your video. It solved my problem, saving me money and aggravation. Very grateful.
Awesome vid. I had 3 dead batteries and I thought it was because of my cordless skill saw. I was getting ready to call DeWalt and give them an earful. Tried it on the first dead battery and now charging perfectly. Thank you.
Brilliant. Just received two replacement batteries from deWalt and one stopped charging after a week. I pulled the two originals out of the garbage, did this procedure, and now have 4 working batteries.
Your solution worked just like you said. We had 2 completely dead batteries. We used a Milwaukie battery to jump start them for about 15 seconds. Plugged the Dewalt batteries in and they both started charging. WTG
I just discovered it doesn't necessarily even have to be a good battery that kick starts it again. I had two dead batteries. Both DCB201. One wouldn't show any lights at all when put on the charger, and the other would just give a solid red light a second after putting it on.

I linked them together like this video, and now both have fully charged, and neither would before.

these lithium batteries chargers will not charge a battery that has been fully discharged. This because when the lithium batteries get below a certain charge level they become unstable . by lifting the charge above that level you fooled the battery charger into thinking the battery had not been fully discharged.
My husband has been going back and forth with Dewalt regarding his brand new 3ah 20v Lithium batteries. He bought the 18v to 20v adapters for his cordless tools and so fare has had to return (4) batteries because of this exact problem. He even bought a brand new 2 pack from Home Depot thinking that Dewalt was sending him refurbished batteries. I'll show him this video to see if this works. Thanks for posting.
Thanks for sharing ! You just saved me $400 for 2 40v lithium ion batteries, I used my charged 20v porter cable battery to bring my Dewalts back to life !! 😂😂
Trevor - glad I could help, discovered that a few tools just drain the battery when left connected - so now I just disconnect the batteries from the tools when not in use.
Keith that’s what I plan to do from now on, I have the leaf blower and weed eater and I just left them in but now I’ll remove them after use and hopefully that works
That worked for me too! My usb phone charger attachment to deWalt battery completely drained the battery and charger wouldn’t recognize it, but that’s the solution I was looking for. Thanks!
Michael Branning - excellent glad I could help - FYI: I had one of my DeWalt tools that was draining my battery’s so now I disconnect the tools from the battery when I’m done using them
Great video. Thanks for demonstrating with very good details of exactly what you did. I especially appreciate showing exactly how you connected the wires.
Yes this works. I actually had to do it a few times. While completely draining the battery a few times in between attempts. Don’t get discouraged if this doesn’t work the first time. It will eventually!

I was online looking to buy a replacement and stumbled across this video. Dead battery shows charging as I type this. Fingers crossed, I'll know in about an hour. Much thanks.
This solution seems to work for so many people however in my case that did not solve it. I got a brand new battery that wouldn’t charge. The problem was the ID resistor was not present at the ID pin in order for the charger to recognize the battery. I ended up bypassing a wire from that resistor on the internal pcb to ground (negative) and now the battery works great!

I just received in the mail my like new Dewalt DCD777 1/2" drill,but it only came with 1 battery so about to order another one and glad I saw this video..if needed I will do this to mine.. Even though haven't needed to do this yet this looks like the way to go before throwing used battery out and buying new.
This has been driving me nuts for 2 years. Bought new charger and battery following dewalt customer service advice and still have the same issue. This worked a treat. Shocking from DEWalt I’ll never buy anything again from them thankfully I only have one battery powered tool from DE-Walt
Joseph Smeath - glad it helped, I'm all about saving money if possible - too bad Dewalt didn't work this solution into their charger, and also they aren't helpful about this when you call crust service
Jadon Spazz - yep same solution for the 207, glad I could help, especially since the 207 is even pricier - I have 4 of those myself note 1: if there is a damaged internal cell (one of the individual batteries within the battery pack) this solution doesn’t work long term Note 2: I now store and travel w/ my batteries and tools disconnected from each other
BINGO IT WORKED even with doing it with a 20 vlt and a 40 volt dcb 404!! I needed 2 so save 400 buckaroonies! Thank you sir you in my prayers lol Be careful positive neg post are opposite on these batteries
Tom Richey, glad it worked for you, it's not just the money we make, it's the money we get to keep too - glad I could help you save a battery and some paycheck - please subscribe and will post some more videos soon
Very good video, definitely trying this later! I just found out one of mine isn't responding on the charger. If this saves the day that's worth $$. Thanks for the video!
I wired my batteries together and let the current flow between them for 15 seconds and VIOLA it works! Very nice, makes me wonder why they won't charge when they go completely dead. Similar to golf cart batteries you've got to put current through them if they get too low or the same issue arises. Curious.. Anyway, Thanks again!
I just bought a 5 amp 20 v battery. It had 1 bar and when I plugged it in for several hours, it still would not charge. I unplugged the charger and plugged it back in and BAM! It charged.
thanks for the video . . . . I bought the 20 volt Li-Ion upgrade kit for my 18 volt stuff. I can NEVER get over two green lights on the batteries. ?????
I just used a 20v 2a to jump a 20v 4a..it worked! My 20v blower is killing my batteries when left in a day or so when not in use. I'm assuming the blower has a short causing this problem? It's just a year old or so. Thanks for the video.
Glad I could help, I’ve had a few tools that if I leave the battery clipped in to that tool, it will discharge my battery below the min threshold for the charger to recognize the battery - this is bad for battery health and just downright annoying - I now always pull all of my batteries from all tolls at the end of a day by habit. Good luck, glad my video helped!
sharpeye83 - watch that batter - I had one that charged fine - and then another one of mine that actually had a failed cell - It soon failed completely and required that I rebuild the cell pack (It cost me about $30-40, took about 1-2 hours and I added a lot more battery umph while I was at it - I didn’t make a video (had audio problems) but this is a great example of how to do it if you end up needing to rebuild yours: ua-cam.com/video/3zhOpgZPoy8/v-deo.html Note: go with good “name brand” batteries, don’t use the cheap Chinese batteries
Keith Farnsworth thank you. I will keep an eye on it. This is the first time I’ve tried this so I appreciate the early warning on potential problems. How long did it take before that battery failed?
sharpeye83 - on the one battery I had that did actually fail due to a cell, it was about 1-2 weeks later, and when I opened the battery (requires a security torex (T-15 if I remember correctly - Harbor Freight sells a 100-pc set of security bits for $10) it was pretty obvious on mine what had happened, one of the cells was slightly bulging and was leaking. So I ordered a full set of 18650 Li-ion replacement cells from Amazon, (I used Amazon because of their return policy if fake/Chinese knock-offs, on eBay you’re more likely to get knockoff’s) lots of videos on how to tell fakes, look, color, weight etc., - hope your’s was just a fully drained battery and no issues beyond a good charge - Good Luck !!
sharpeye83 - I noted a problem with the battery that had the failed cell wouldn’t hold a charge beyond a few days (discharging without any load), then wouldn’t charge at all, even with the above method, opened it and found the one cell that had failed was bulging and leaking -
Dang i jumped started an it sparked thought i had burnt the battery, little smoke, left it for about 5 seconds and i started charging it and it worked,, will let it charge hopefully it starts working as usual... will get back to u guys if not that might be because i have no complaints but so far theres signs of life jeje

Battery works now video was really helpful and yes thats exactly what happened i let my battery sit for so long discharged that it completely died on me... very helpful sir
@@beyondthebirdhouse4796 that just happened to me memorial day when a neighbors tree got blown down. Was using my jigsaw to help cut it up and had a battery shoot shyt. Gonna do this tonight. You got a sub for sure !!
Lithium batteries will self protect when they reach a low voltage threshold. They go into a “ sleep” mode. This technique wakes them up and they take a charge again. It’s the same in these, car, motorcycle, any lithium batteries. In a vehicle, you turn it on for thirty seconds, then off 3-5 times to wake the battery. If that doesn’t work you can “ fool” the battery like here.
worked for me and my neighbour also. i should of realised since ive done the same with 18650 batteries before. also would be easier if we had dumb chargers that send power regardless instead of intellicharging lol thanks +1 like
@@ezequielfuentes1823 You're a fucking moron. Two batteries at my local Lowes are $149.99 for the pair, as you cannot buy just one, and you telling him to quit being cheap and throw away his brand new battery that should've worked ”out of the box” is outlandish, at best!!! GTFOH!!!
Awesome!! After watching a few worthless videos, I was about to throw the battery away. But then I watched this one! Worked like a charm and it’s back to normal! Thank you!!!
Thank you so much! The battery was totally dead and nothing happened when I tried to charge. I did exactly what you showed in the video and the charger has the battery in it and finally it’s flashing!
I tried you jumper cable fix on an almost new battery that came with my DeWalt lug gun that would not take a charge. Your solution worked like a champ! Many thanks!!!
Wow, fantastic! My 5AH battery is only 6 months old so I was searching for the warranty process when I found this. You have probably saved me a ton of time and aggravation. My battery is now charging and suspect will work fine later today. Thank you.
You're a lifesaver because I just brought a weed eater hedger that came with a b16-2025 battery that didn't take a charge. So I followed your instructions and the battery is now charging. Now I got 2 working batteries. Thank you very much!!!
Thanks for posting this! When I realised just a tiny power boost might trigger the battery enough, I tried this- I put it on my 3/8 impact driver and spun it by hand for about 10 seconds. In theory this would put charge into the battery. It worked! Put it on the charger and the light came right on.
Thank you so much for this. I had the same issue with a brand new tool , came with 2 batteries. One charged, one did not. This fix absolutely did work.
You saved the day my friend. I picked up a Dewalt DCD795 open box from Lowe's with 2 dead 203BT batteries....hence the cheap price. Hooked them both up to my good battery from my other Dewalt driver and now I have 2 functioning batteries.
Excellent fix. Saved a 20v, 4.0Ah triton battery that now costs $100. Pay close attention to the "just a second." I did it longer and nearly overheated the battery. Looked at other fixes; don't have a 20v controlled power supply. Using the other battery (carefully) is just one of those head-slapping, why-didn't-I-think-of-that ideas. Careful with the polarity, just a second, and don't let your batteries get completely drained. Thanks, BTB!
Sir, THANK YOU SO MUCH! I went to use my Dewalt 20V sander with a 2 year old Dewalt battery that was attached and it was dead. I tried to charge and it wouldn't, I found your video and did exactly what you said and, PRESTO! New battery that charges!! Thank you, those batteries are $75 here in Palm Springs, CA
Kesh Patel - glad it helped ! Note - 2 of my tools drain the battery if left in the tool during storage, so now I always disconnect the battery when done - also if a cell in the battery pack goes bad it can/will drain the other cells, requiring you to rebuild the battery pack or replace it - thanks for the feedback
That you so much! I was pissed my brand new 5AH battery would do anything. I am still very disappointed with DeWalt for not making a fix for this before putting it to market. They knew about this problem for sure, two of my batteries had this same problem. The fix would have been easy to integrate into the changer.
It’s not a Dewalt problem. The problem is with your supplier keeping there Dewalt tools stocked for way too long. Batteries self discharge if left on a shelf for too long, to the point that the charger doesn’t recognize when a battery is out on.
@@frankjackson2439 that would directly be a dewalt problem then if the charger (The dewalt charger) doesn't recognize the battery for a known issue such as this.
Jason Lefevers - I’ve found it can be a tool that will drain the battery if left in tool for storage - On one of my batteries it had a damaged cell, that would drain the other cells (if that’s the case, then the only solution is to rebuild the battery cell pack).
It’ll happen if the battery fully discharges, for example if it’s left in a tool that’s on (like a flashlight) or attached to one of those adapters that lets you use the new style batteries with the older DeWalt tools. The battery has a built in protection circuit that shuts itself off if the battery is overdischarged. Connecting the other battery resets this circuit.
This is a very helpful video! I followed your tips and my battery is now back as normal after an hour of charging. Glad that I did not throw it away. Again Thanks and greatly appreciated!
Long past since you made this video but the solution to the problem is ,new. Thanks so much for your video instruction. I can't believe something works as advertised from You Tube. You the Man,Bro. Thanks again!
Dylan Wood - glad it helped, I used speaker wire but any wire would work that is a moderate gauge - (I wouldn't do this with ultra thin gauge) great MacGyver quick solution using the foil !
I just got two of the 20v batteries about 6 months ago and went to charge one and this exact thing happened. If I didn't find your video I would've ended up going through some warranty bs. This worked like a charm! Thank you!!!
Thank you very much from NC! I was going nuts trying to figure out why a fairly new 5 AH (and those puppies are expensive!) battery wouldn't charge. Your trick solved it in 5 seconds. :-) Much appreciated!
Joe - it happens when the battery discharges below the threshold for the charger to recognize it. Cause for me has been 1) a tool that over drained the battery (fixable using this technique) - I now disconnect my batteries from tools for storage and transport 2) can also be caused by one of the internal cells failing and then draining the other cells (in that instance, my video will not fix the battery pack, and would require rebuilding/replacing the internal cells within the battery pack)
Worked like a charm! I had the same problem with two 20v 5AH batteries that would not even charge on the charging dock... Charging dock would not even blink red or nothing! Was about to contact Dewalt, but found this fix and now it’s charging again! Thanks!
Andrew - I ended up applying this solution to two of my dewalt 20v batteries (apparently my dewalt flashlight will run them down too far to be recognized to charge) - my results were mixed on one battery 4A worked fine and is still going strong, on the other battery the 2A it charged but then rapidly failed - upon opening the battery pack it was discovered that there was a failed cell - so I replaced the set of batteries and rebuilt the battery pack (cost about$37) - has worked fine every since , I recommend reading on the poor quality/relabeled LiIon batteries from China before you rebuild, so you know what to avoid.
Andrew - here’s the how-to video that I used: ua-cam.com/video/3zhOpgZPoy8/v-deo.html Re: the batteries - Panasonic, Sanyo, Orbtronic, Samsung, and LG are the top level 18650 cell manufacturers, making long lasting cells, Chinese knockoffs are available for cheaper, but are prone to shorter lifespans and aren’t always uniform size.
Thank you so much for the tip, really appreciate the info. I ran into the same issue and got it fixed by watching your video. Thanks again for sharing this information. You are a rock star.
Some perspective from someone who flies large scale RC helicopters and has been working with high performance, high capacity LiPo batteries for several years. The DeWalt batteries have an over discharge protection circuit built in. If the battery is discharged beyond a certain voltage, the DeWalt system will not allow you to charge the battery. Your fix is circumventing that circuit by directly adding charge to the battery, lifting the charge above the low charge threshold. You really are jump starting the damaged battery, and it really does work. The reason the battery is warm to the touch when charging is because the battery is damaged; Discharging a LiPo battery too much damages the battery. In a car battery (lead acid), after 2-3 discharges, the battery will no longer have the amps (torque) needed to start the car. In damaged LiPo batteries, the batteries get hot and puff (literally get bigger) when charged and discharged. The battery will not have as many amps (torque), the individual battery cells will have a higher internal resistance, and the battery pack will get hot when you use it. For batteries in hard cases, this puffing could lead to a battery puncture and fire. This is why the protection circuit exists in these batteries. I'm not saying "don't do this" (we all want to save money); I'm saying 1) Do not over discharge your batteries, 2) if you do this, be extra careful with the batteries you have done this to, because they will be prone to puffing and eventual rupture and fire, and 3) batteries that are over-discharged will not have the same punch as batteries that have not been abused. Reminder this is the same battery type used in Sony laptops, Samsung phones, and the Boeing 787 Dreamliner; these batteries absolutely will catch fire if abused. Do not over-discharge your batteries. It's the internet; believe what you want. I'm not product bashing, I have no incentive to mislead you, and my message is caution and safety and please don't burn your house down. Good luck! :o) Related searches: - "Tareq Alsaadi Goblin" for big LiPo batteries in high performance RC heli flight - "lipo nail" for what a LiPo fire looks like - "lipo fire house" for the worst case scenario Nerdy stuff: - LiPo batteries are made up of individual LiPo cells - Based on the number of connectors (main + x1, main - x1, balance - x1, balance + x5 = 8 leads), this is a 5 cell LiPo pack (if you opened up the battery, you would find 5 individual cells) - Those extra leads are for balance charging. The charger will (or "should") charge or discharge each LiPo cell independently - When fully charged, each LiPo cell should read 4.20v, and the whole battery pack will read 21v - Storage voltage for optimal battery life is 3.86v per cell, or 19.3v for the whole pack - Really don't want to go beyond 3.74v per cell when discharging, or battery life will be shortened, the battery will lose punch (amps), and the battery will start to puff and get hot when used - LiPo batteries absolutely do not last forever, even in optimal use circumstances
ImTimay2 - love your comments - and totally agree on almost every point, My complaint lies in the design from the Dewalt system - excessive battery discharge does occur in some of their tools (by design or rather lack of design) and the circuitry designed to prevent the excessive discharging fails to preform effectively, thereby rendering the battery useless - I’m proposing a potential bridge solution, vs just discarding and replacing the battery - I agree with you that that there are potential negative side effects, I also believe we shouldn’t have excessive waste, disposing of batteries that still have plenty of use left in them
ImTimay2 way too many people who are doing this don’t understand what they are doing and are just asking for trouble and have a ticking time bomb. They have these safeties for a reason people like this make upset because they clearly don’t have a understanding what they are doing. Wait till he gets sued because someone burns their home down
zack9912000 if u do this once you will not have an issue. My battery was dead from the start, I been busy working and never took it back. Yea I should have but at time couldn't and before knew it, was to late to even consider taking back. I don't ever totally discharge my batteries, I'm an rc guy myself, 4s summit all day!!

I’ve found through trial and error: A) keep my batteries charged before storage, and B) separate the battery from the tool when storing or transporting - ever since I’ve done that I haven’t had a battery fully discharge and refusing to charge
2) the second reason a battery drains below charger recognition is due to a failed cell(s) within the battery pack that then drains the other cells - unfortunately my video won’t correct this issue (it might temporally, but the battery pack will discharge rapidly again) ~ if this occurs, obviously use your warranty if available - if you don’t have a warranty option then, athough it’s not my video, here’s a video I recommend that shows you how to rebuild the battery pack (thereby replacing a damaged/failed cell/cells) :

I just received in the mail my like new Dewalt DCD777 1/2" drill,but it only came with 1 battery so about to order another one and glad I saw this video..if needed I will do this to mine..
Even though haven't needed to do this yet this looks like the way to go before throwing used battery out and buying new.
I now always separate my battery from my tools for travel or storage
Just fixed two of my Dewalt batteries using your method. Thanks a bunch!
Thank you so much! My battery is back alive after several months of storage and just about to recycle it.
Roch-Yves Vallieres - glad I could help!
This has been driving me nuts for 2 years. Bought new charger and battery following dewalt customer service advice and still have the same issue. This worked a treat. Shocking from DEWalt I’ll never buy anything again from them thankfully I only have one battery powered tool from DE-Walt
this video saved me 120 nz dollars as we get ripped over here for any dewalt product. our version is the 18v thanks heaps for posting this video
Joseph Smeath - glad it helped, I'm all about saving money if possible - too bad Dewalt didn't work this solution into their charger, and also they aren't helpful about this when you call crust service
Just worked for me! Brought back an older 20v Max battery (with a little spark)
YOU A-R-E the man. This worked out perfectly for me.
worked great with DCB207 battery!! Thank you.
Jadon Spazz - yep same solution for the 207, glad I could help, especially since the 207 is even pricier - I have 4 of those myself
note 1: if there is a damaged internal cell (one of the individual batteries within the battery pack) this solution doesn’t work long term
Note 2: I now store and travel w/ my batteries and tools disconnected from each other
Wow i figured I had killed that battery when I was running the kids powerwheels off it. Worked like a charm with the DCB204. Thanks a ton.
167Maverick - glad it helped you !!
How did u convert this battery to power wheels connector
Thank you so much!! You saved me 89 dollars!! Now my heated jacket has a battery that works.
Thanks. Followed directions and it worked perfectly...
worked perfectly thanks for the video
Przemek Gorka - so glad it helped you !!
Thank you I am so greatful for this video. I am subscribed. I can't tell you how stressed I was until this worked 100 percent first try.
Kesotone - glad I could help - hope this helped to de-stress!!
BINGO IT WORKED even with doing it with a 20 vlt and a 40 volt dcb 404!! I needed 2 so save 400 buckaroonies! Thank you sir you in my prayers lol Be careful positive neg post are opposite on these batteries
Fantastic - glad I could help!
Add one more to the "it works" list. Thanks for the tip!
Thank you for the feedback - glad I could help
SOB, that worked. Thank you man. Saved me 100
This solution absolutely works. Thanks for sharing.
Tom Richey, glad it worked for you, it's not just the money we make, it's the money we get to keep too - glad I could help you save a battery and some paycheck - please subscribe and will post some more videos soon
excellent video! exactly addresses my problem on a different device (mower battery).thank you. worked perfectly!
It worked! Thank you... i hate replacing my company stuff early
noah - glad I could help 👍
Very good video, definitely trying this later! I just found out one of mine isn't responding on the charger. If this saves the day that's worth $$.
Thanks for the video!
I wired my batteries together and let the current flow between them for 15 seconds and VIOLA it works! Very nice, makes me wonder why they won't charge when they go completely dead. Similar to golf cart batteries you've got to put current through them if they get too low or the same issue arises. Curious.. Anyway, Thanks again!
I just bought a 5 amp 20 v battery. It had 1 bar and when I plugged it in for several hours, it still would not charge. I unplugged the charger and plugged it back in and BAM! It charged.
LeRoy - glad you’re up and going, watch that battery, save your receipt and warranty early on if needed 😉
Thank you sir!!! Worked for me! GODS BLESS!!!
thanks for the video . . . . I bought the 20 volt Li-Ion upgrade kit for my 18 volt stuff. I can NEVER get over two green lights on the batteries. ?????
Worked like a charm! Thanks for the great tutorial.
Richard - glad I could assist!
this worked like a charm!! thank you so much!!awesome and easy solution!
Cecilia Lydolph - glad I could help!
🤣🤣Awesome thank you for doing the research for me! Cheerz! Wonked like a charm !
thanks brother. you save me from getting a new battery at home Depot. thanks
Peng Thao - glad I could help!
I just used a 20v 2a to jump a 20v 4a..it worked! My 20v blower is killing my batteries when left in a day or so when not in use. I'm assuming the blower has a short causing this problem? It's just a year old or so. Thanks for the video.
Glad I could help, I’ve had a few tools that if I leave the battery clipped in to that tool, it will discharge my battery below the min threshold for the charger to recognize the battery - this is bad for battery health and just downright annoying - I now always pull all of my batteries from all tolls at the end of a day by habit. Good luck, glad my video helped!
Thank you! Worked perfectly! ...and thanks for the heads up... mine also got a little hot while charging afterward
sharpeye83 - watch that batter - I had one that charged fine - and then another one of mine that actually had a failed cell - It soon failed completely and required that I rebuild the cell pack (It cost me about $30-40, took about 1-2 hours and I added a lot more battery umph while I was at it -
I didn’t make a video (had audio problems) but this is a great example of how to do it if you end up needing to rebuild yours:
ua-cam.com/video/3zhOpgZPoy8/v-deo.html
Note: go with good “name brand” batteries, don’t use the cheap Chinese batteries
Keith Farnsworth thank you. I will keep an eye on it. This is the first time I’ve tried this so I appreciate the early warning on potential problems. How long did it take before that battery failed?
sharpeye83 - on the one battery I had that did actually fail due to a cell, it was about 1-2 weeks later, and when I opened the battery (requires a security torex (T-15 if I remember correctly - Harbor Freight sells a 100-pc set of security bits for $10) it was pretty obvious on mine what had happened, one of the cells was slightly bulging and was leaking. So I ordered a full set of 18650 Li-ion replacement cells from Amazon, (I used Amazon because of their return policy if fake/Chinese knock-offs, on eBay you’re more likely to get knockoff’s) lots of videos on how to tell fakes, look, color, weight etc., - hope your’s was just a fully drained battery and no issues beyond a good charge - Good Luck !!
Keith Farnsworth this is all excellent info. Really appreciate this!
sharpeye83 - I noted a problem with the battery that had the failed cell wouldn’t hold a charge beyond a few days (discharging without any load), then wouldn’t charge at all, even with the above method, opened it and found the one cell that had failed was bulging and leaking -
This 100% works, I used paper clips.
It worked. Thank you!
Dang i jumped started an it sparked thought i had burnt the battery, little smoke, left it for about 5 seconds and i started charging it and it worked,, will let it charge hopefully it starts working as usual... will get back to u guys if not that might be because i have no complaints but so far theres signs of life jeje

Awesome i just got 3 batteries back to life
Freaking awesome brotha!! Thanks
Daniel - Happy to help - we can all use to save a little time and $$
@@beyondthebirdhouse4796 that just happened to me memorial day when a neighbors tree got blown down. Was using my jigsaw to help cut it up and had a battery shoot shyt. Gonna do this tonight. You got a sub for sure !!
Lithium batteries will self protect when they reach a low voltage threshold. They go into a “ sleep” mode. This technique wakes them up and they take a charge again. It’s the same in these, car, motorcycle, any lithium batteries. In a vehicle, you turn it on for thirty seconds, then off 3-5 times to wake the battery. If that doesn’t work you can “ fool” the battery like here.
worked for me and my neighbour also. i should of realised since ive done the same with 18650 batteries before. also would be easier if we had dumb chargers that send power regardless instead of intellicharging lol thanks +1 like
👍🏻 worked for me!
Worked! Thank you!
Worked like a charm
Just simply jump start! The battery charger senses 0V as defective.
Victor - hope this helped
A easier way is to use a 18v adapter and plug into 18v charger for a 4 seconds then plug back into the 20v charger and it will charge correctly.
After 2 years of my husband trying to get his 2nd battery to light up on the charger...u saved the day by ur video! Thanks!
Melissa - glad we could help, 2 years is too long to go with out a backup battery
Tell him to buy a new one and stop being cheap
@@ezequielfuentes1823
You're a fucking moron. Two batteries at my local Lowes are $149.99 for the pair, as you cannot buy just one, and you telling him to quit being cheap and throw away his brand new battery that should've worked ”out of the box” is outlandish, at best!!! GTFOH!!!
So glad for your husband!
No guy is happy when his battery won't light up the charger. (Including me!)
Awesome!! After watching a few worthless videos, I was about to throw the battery away. But then I watched this one! Worked like a charm and it’s back to normal! Thank you!!!
Worked! Thank you!!
Thank you so much! The battery was totally dead and nothing happened when I tried to charge. I did exactly what you showed in the video and the charger has the battery in it and finally it’s flashing!
Patrick Castillo - glad I could help
I tried you jumper cable fix on an almost new battery that came with my DeWalt lug gun that would not take a charge. Your solution worked like a champ! Many thanks!!!
Wow, fantastic! My 5AH battery is only 6 months old so I was searching for the warranty process when I found this. You have probably saved me a ton of time and aggravation. My battery is now charging and suspect will work fine later today. Thank you.
It seems like a scam but the battery is charging now.
@@dwightlembke3930 yeah on Dewalt's part definitely a scam I got a flexfuel battery used like 5 times that stopped working.
You're a lifesaver because I just brought a weed eater hedger that came with a b16-2025 battery that didn't take a charge. So I followed your instructions and the battery is now charging. Now I got 2 working batteries. Thank you very much!!!
Thanks for posting this!
When I realised just a tiny power boost might trigger the battery enough, I tried this- I put it on my 3/8 impact driver and spun it by hand for about 10 seconds. In theory this would put charge into the battery. It worked! Put it on the charger and the light came right on.
Thank you so much for this. I had the same issue with a brand new tool , came with 2 batteries. One charged, one did not. This fix absolutely did work.
You just pissed off dewalt lmao score one .
You saved the day my friend. I picked up a Dewalt DCD795 open box from Lowe's with 2 dead 203BT batteries....hence the cheap price. Hooked them both up to my good battery from my other Dewalt driver and now I have 2 functioning batteries.
panthrosan - great score on the open box, and glad it helped 1) to get them working 2) to save some cash
Amazing, the hack is still working 2019 !! Thanks man !
Excellent fix. Saved a 20v, 4.0Ah triton battery that now costs $100. Pay close attention to the "just a second." I did it longer and nearly overheated the battery. Looked at other fixes; don't have a 20v controlled power supply. Using the other battery (carefully) is just one of those head-slapping, why-didn't-I-think-of-that ideas.
Careful with the polarity, just a second, and don't let your batteries get completely drained. Thanks, BTB!
Glad I could help
Unbelievable! And so simple. A time saver and money saver. Thanks for sharing your knowledge.
Sir, THANK YOU SO MUCH! I went to use my Dewalt 20V sander with a 2 year old Dewalt battery that was attached and it was dead. I tried to charge and it wouldn't, I found your video and did exactly what you said and, PRESTO! New battery that charges!! Thank you, those batteries are $75 here in Palm Springs, CA
No freaking way! I'm so glad I looked before buying new! They're so expensive. Thank you thank you thank you! 127 Dewalt resellers disliked
Wow no joke. I seriously thought they had to be sent back. Both of my batteries started to charge... awesome!!
Kesh Patel - glad it helped !
Note - 2 of my tools drain the battery if left in the tool during storage, so now I always disconnect the battery when done - also if a cell in the battery pack goes bad it can/will drain the other cells, requiring you to rebuild the battery pack or replace it - thanks for the feedback
That you so much! I was pissed my brand new 5AH battery would do anything. I am still very disappointed with DeWalt for not making a fix for this before putting it to market. They knew about this problem for sure, two of my batteries had this same problem. The fix would have been easy to integrate into the changer.
It’s not a Dewalt problem. The problem is with your supplier keeping there Dewalt tools stocked for way too long. Batteries self discharge if left on a shelf for too long, to the point that the charger doesn’t recognize when a battery is out on.
@@frankjackson2439 that would directly be a dewalt problem then if the charger (The dewalt charger) doesn't recognize the battery for a known issue such as this.
@@frankjackson2439 I just got done using mine on a dewalt pole saw and now they won't charge. Not sure what that has to do with suppliers...
Worked for 2 of my batteries I thought were garbage. Thanks!
Kyle Smietanski - glad I could help
Awesome. I will try now.
Yep works! Thanks! I've done a similar thing with golf carts since the relay needs a minimum voltage to turn on the charger.
Carl Zirk - glad this video helped - good luck (hope it’s just over discharged and not due to a failed cell)
Amazing. I had the same issue with a practically brand new battery and this worked perfectly. I wonder what causes these batteries to do this.
Jason Lefevers - I’ve found it can be a tool that will drain the battery if left in tool for storage -
On one of my batteries it had a damaged cell, that would drain the other cells (if that’s the case, then the only solution is to rebuild the battery cell pack).
It’ll happen if the battery fully discharges, for example if it’s left in a tool that’s on (like a flashlight) or attached to one of those adapters that lets you use the new style batteries with the older DeWalt tools.
The battery has a built in protection circuit that shuts itself off if the battery is overdischarged. Connecting the other battery resets this circuit.
Just tried it on my dead battery and its now charging! Amazing fix. Thanks a million for your expertise.
Andrew - glad we could help!
This is a very helpful video! I followed your tips and my battery is now back as normal after an hour of charging. Glad that I did not throw it away. Again Thanks and greatly appreciated!
Long past since you made this video but the solution to the problem is ,new.
Thanks so much for your video instruction.
I can't believe something works as advertised from You Tube.
You the Man,Bro. Thanks again!
wow this worked like a champ for me. couldn't find any loose speaker wire so I used foil and I'll be damned if it didn't work. thanks bro.
Dylan Wood - glad it helped, I used speaker wire but any wire would work that is a moderate gauge - (I wouldn't do this with ultra thin gauge) great MacGyver quick solution using the foil !
I just got two of the 20v batteries about 6 months ago and went to charge one and this exact thing happened. If I didn't find your video I would've ended up going through some warranty bs. This worked like a charm! Thank you!!!
I have a couple of the 4ah batteries that I can now save. Thanks for sharing
Mymanmark - glad I could assist
Great tip! Thank! I just "fixed" one of my dead batteries and save myself a bunch of money not having to buy a new battery..
Gosh! Just fixed 5 genuine batteries! I was very sceptical, but thought I'll try. Genius!! Thanks :)
It effin worked ! Thanks !
Alex Lopez - awesome, glad to help
Thank you very much from NC! I was going nuts trying to figure out why a fairly new 5 AH (and those puppies are expensive!) battery wouldn't charge. Your trick solved it in 5 seconds. :-) Much appreciated!
Chris Coffey - awesome, glad I could help - I’m now taking my batteries out of all of my tools - and I don’t get the Bluetooth batteries anymore
Worked spot on, thanks. Do you know why this occurs?
Joe - it happens when the battery discharges below the threshold for the charger to recognize it.
Cause for me has been 1) a tool that over drained the battery (fixable using this technique) - I now disconnect my batteries from tools for storage and transport
2) can also be caused by one of the internal cells failing and then draining the other cells (in that instance, my video will not fix the battery pack, and would require rebuilding/replacing the internal cells within the battery pack)
Great tip. Worked perfectly on two new batteries which had totally discharged and I thought were faulty. Thank you
Worked like a charm! I had the same problem with two 20v 5AH batteries that would not even charge on the charging dock... Charging dock would not even blink red or nothing! Was about to contact Dewalt, but found this fix and now it’s charging again! Thanks!
GT-BMX-RIDER - awesome, glad I could be of assistance !
So, its been 20 months or so since you executed this fix. Is the battery still functioning perfectly now? How about an update?
Andrew - I ended up applying this solution to two of my dewalt 20v batteries (apparently my dewalt flashlight will run them down too far to be recognized to charge) - my results were mixed on one battery 4A worked fine and is still going strong, on the other battery the 2A it charged but then rapidly failed - upon opening the battery pack it was discovered that there was a failed cell - so I replaced the set of batteries and rebuilt the battery pack (cost about$37) - has worked fine every since , I recommend reading on the poor quality/relabeled LiIon batteries from China before you rebuild, so you know what to avoid.
Thanks for the prompt reply. Did you buy a set of matching A-hr 18650s from Amazon?
Andrew - here’s the how-to video that I used:
ua-cam.com/video/3zhOpgZPoy8/v-deo.html
Re: the batteries - Panasonic, Sanyo, Orbtronic, Samsung, and LG are the top level 18650 cell manufacturers, making long lasting cells, Chinese knockoffs are available for cheaper, but are prone to shorter lifespans and aren’t always uniform size.
I was half way through my rebuild before I realized I hadn’t hit start on my record button so missed making that video -
Thank you so much for the tip, really appreciate the info. I ran into the same issue and got it fixed by watching your video. Thanks again for sharing this information. You are a rock star.
Some perspective from someone who flies large scale RC helicopters and has been working with high performance, high capacity LiPo batteries for several years.
The DeWalt batteries have an over discharge protection circuit built in. If the battery is discharged beyond a certain voltage, the DeWalt system will not allow you to charge the battery. Your fix is circumventing that circuit by directly adding charge to the battery, lifting the charge above the low charge threshold. You really are jump starting the damaged battery, and it really does work.
The reason the battery is warm to the touch when charging is because the battery is damaged; Discharging a LiPo battery too much damages the battery. In a car battery (lead acid), after 2-3 discharges, the battery will no longer have the amps (torque) needed to start the car. In damaged LiPo batteries, the batteries get hot and puff (literally get bigger) when charged and discharged. The battery will not have as many amps (torque), the individual battery cells will have a higher internal resistance, and the battery pack will get hot when you use it. For batteries in hard cases, this puffing could lead to a battery puncture and fire. This is why the protection circuit exists in these batteries.
I'm not saying "don't do this" (we all want to save money); I'm saying 1) Do not over discharge your batteries, 2) if you do this, be extra careful with the batteries you have done this to, because they will be prone to puffing and eventual rupture and fire, and 3) batteries that are over-discharged will not have the same punch as batteries that have not been abused. Reminder this is the same battery type used in Sony laptops, Samsung phones, and the Boeing 787 Dreamliner; these batteries absolutely will catch fire if abused.
Do not over-discharge your batteries.
It's the internet; believe what you want. I'm not product bashing, I have no incentive to mislead you, and my message is caution and safety and please don't burn your house down. Good luck! :o)

Nerdy stuff:
- LiPo batteries are made up of individual LiPo cells
- Based on the number of connectors (main + x1, main - x1, balance - x1, balance + x5 = 8 leads), this is a 5 cell LiPo pack (if you opened up the battery, you would find 5 individual cells)
- Those extra leads are for balance charging. The charger will (or "should") charge or discharge each LiPo cell independently
- When fully charged, each LiPo cell should read 4.20v, and the whole battery pack will read 21v
- Storage voltage for optimal battery life is 3.86v per cell, or 19.3v for the whole pack
- Really don't want to go beyond 3.74v per cell when discharging, or battery life will be shortened, the battery will lose punch (amps), and the battery will start to puff and get hot when used
- LiPo batteries absolutely do not last forever, even in optimal use circumstances
ImTimay2 - love your comments - and totally agree on almost every point,
My complaint lies in the design from the Dewalt system - excessive battery discharge does occur in some of their tools (by design or rather lack of design) and the circuitry designed to prevent the excessive discharging fails to preform effectively, thereby rendering the battery useless - I’m proposing a potential bridge solution, vs just discarding and replacing the battery - I agree with you that that there are potential negative side effects, I also believe we shouldn’t have excessive waste, disposing of batteries that still have plenty of use left in them
ImTimay2 way too many people who are doing this don’t understand what they are doing and are just asking for trouble and have a ticking time bomb. They have these safeties for a reason people like this make upset because they clearly don’t have a understanding what they are doing. Wait till he gets sued because someone burns their home down
zack9912000 if u do this once you will not have an issue. My battery was dead from the start, I been busy working and never took it back. Yea I should have but at time couldn't and before knew it, was to late to even consider taking back. I don't ever totally discharge my batteries, I'm an rc guy myself, 4s summit all day!!
These batteries are not LiPo (lithium polymer) these have 5 lithium ion 18650 cells inside the packs.
shhhh
What if my battery chargs but doesnt work with any of my tools my impact driver lights just flash
Jonathan - sounds like either a pin issue, or a battery circuit failure
Im having the same issue, let me know if you found a solution
Abolutely brilliant. So glad I stumbled upon your video. Saved me a lot of money. Thanks a million.
THANK YOU!! I just purchased a DeWalt impact driver that had an extra battery. One would charge, one would not...
I contacted the seller on Amazon and they said to contact warranty service. After trying your "Fix", the battery now charges.
You saved me a trip and a couple of hours out of my already busy day.
David - glad I could help !!
