WOW!!! I can't believe that worked. I got 2 dewalt 20v (2ah) batteries from a store that was throwing them away. The customer brought them back because they were dead. I put them on my charger and got nothing. Then I found this video. I used some wire to connect them to one of my battries for about 3 seconds each and now they are charging just fine.I learn something new every day. Thank you 😁😁
THIS WORKED FOR ME!! I didn't have a battery jump starter and read in the comments here someone tried a regular 9v battery...like the kind that goes in a smoke detector... So I also tried a 9v battery with the razer blades and my dcb203 battery is now charging! I threw away at least 4 relatively new batteries recently with the same issue.. I bet all of them could have been jump started like this. THANK YOU !!!
You're right, it's amazing that this needs to be done. Both my 20v batteries stopped charging, no light on the charger. I contacted Dewalt and, to their credit, they were easy to deal with and sent me a new charger. When that didn't work, it was clear to me that it was the battery that was the problem, not the charger. I had even gone to Lowe's and bought another charger, that I was able to return when it didn't help. Thanks for the vid. The batteries are charging right now!
Dude I am going to give this a go tomorrow. I’ve got about 12 - 60V batteries and 2 are dead. I’m sick of spending $200+ for these batteries just for them to bug up within a year. Dewalt needs to make some changes! Thanks for the tip man! 🔥
This worked for me…THANK YOU! 8 month old battery barely used. I suspect it does not like being completely drained, mine was powering the Dewalt inflator airing up an extremely low set of tires. Died while trying to air up the last one. I used my Schumacher battery charger set to 40a, just gave it a quick tap to get a tiny spark. Charging fine now.
I can’t tell you how much this helped me. I just purchased a DeWalt cordless screwdriver for $100 bucks. It came with two batteries, a charger and tool bag so obviously a deal only problem is, the batteries wouldn’t charge. I brought it home and attempted to charge them for three hours and nothing. I found this video and tried it with a battery from a drill I have that does work and presto... the batteries are both now charging. You are a genius. Thank you. I’ll let you know if I get a full charge and a general update.
20v 5AH just worked for me using a spare charged dewalt same style battery. Used 14 AWG speaker wire, two razor blades and two sparks later, battery is now charging /blinking in the charger. U deserve an award.
Watched this and circumstances identical new battery, charger, and just wasn’t used yet. Just went thru very cold weather here in Texas and battery was in truck. Did not really think it would work didn’t seem logical to have to jump start it. Used dimes and IT WORKED - started charging and took a full charge. Totally impressed! Thank You!
Wow, you've just saved me load of cash my friend. I jumped the battery using four blades, two in each of my batteries and it worked straight away. Thanks for the tip .
Thanks a lot for sharing this information. Had a Dewalt battery fail on second charge. Jumped it with a 12v motorcycle battery as you showed. Sparked and is now charing on charger. Excellent! Thanks again!!
Thank you for this video! You saved me a lot of headaches and troubleshooting. I bought a brand new battery and charger kit, used the battery a few times, and then when it came time to recharge the battery for the first time, I was getting no lights on my charger. I was a bit skeptical trying this out. I tried with a 9V battery as some folks said, but that didn't work for me - possibly the battery was just a bit low. I also tried with my portable booster, but that didn't work either for some reason. My final attempt was using booster cables with my car battery. I saw a couple of sparks as you mentioned in the video, brought the battery back in and put it into the charger, and it started charging! (Charger is currently flashing red, which indicates that it is charging). Great trick, thank you!
I tried a few other ways to fix my battery but none work. I used my battery trickle charger and the blades from my razor knife as you demonstrate here. Battery took a full charge and back in business. Thanks so much for your vid!!
My DeWalt 20 V battery- the only 1 have- showed no lights in the charger. Followed this tip with a 6 volt lantern battery with no results. Got out my 12 V car charger and after a spark and 3 secs, all working perfectly. I too used the razor blades, they fit perfectly are eary to connect and readily available in your box knife. :)
Never mind I read some of the other comments and took a stab at it hoping I didn’t fry my 250$ batteries. But it’s worked great. Finally some good info on TH-cam that WORKS!!!! Nice thanks again.
Hello, thank you very much, because I regretted my $280 purchase because the battery does not charge. I followed your video and it worked. Great, thank you again
I can 100% confirm that this works. I've just tried this on a DCB185 battery that would not charge and its now charging! I used two Stanley knife blades and a battery charger set to boost.
It worked great for me I use the battery charger/Maintenance with prong or the circle things and place them in the same locations as you and voila it work once I place it on the dewalt charger.
You're a lifesaver, my DeWalt charger would not light up, no led light on battery either, gave it a jumpstart with my portable AA charger, sorted 😊👍 battery now charging.
Thanks I had a dead 60v Dewalt battery and this worked. Light did not even turn on when checking battery level. Now it works! What I did is that I connected to portable car battery charger left it for 5 minutes and then I connected it the charger and it started charging.
I have the same weed eater, the battery stopped charging (the charger works, just not the battery for this!) Ty for this video I can finally get to work on my crazily over grown yard
I did the utility blades and connected it to my battery tender and tapped the ground, took it back to the charger and it works. I bought a kit from ebay with no returns so this just saved me a good chunk of change.
You saved my battery. I followed this right down to the blades lol. Amazing. easy. Set the booster to 50 amps boost, touched the + three times and now life is perfecto. Thanks very much!
I literally just had this exact scenario happen to me with a 20-volt battery. It's like if you were speaking to me directly. I only had one battery. It worked perfectly. Thank you for making this video!
I've tried on older craftsman battery without luck and then just tried with larger 40v Dewalt. It worked this time but be careful to only do for a few seconds. I had smaller gauge wires connected like this guy and seen wires start to droop after about 8 seconds so I could tell heating up and they were very warm.
Wow 👏 dude awesome trick it saves my battery. I used a Duralast battery charger instead of a jumper starter. After a couple of sparks it was back to the life
Thanks for this video, it helped a lot, i knew about the wire jump from other batteries but all 4 of mine are dead. I used my portable battery car booster to bring the batteries to life, and i wish i knew this last year when i just threw out my 6 batteries which i could have saved.
It work 9.0 dewalt battery wasn't charging i use another dewalt battery and it work just put positive with positive and negative with negative thanks for the video it help alot 👍
Great video showing what to do if you can’t jump start from another battery. My FLEXVOLT has a partial charge and works on tools, but when put in charger, light briefly comes on and then goes off. I’ve tried cleaning the terminals, but makes no difference. Even though the battery still has a charge, would a jump start result in a ‘reset’ which might allow it to charge?
I did it with 3 steak knives, no power source, just stick 2 in the slots according to the video and connect them with the third, it smokes a tiny bit and my knives did a little microscopic weld, then put it back on the charger and it worked like a charm, no longer than 2 seconds connected or else it might mess something up.
It works with another battery u can use speaker wire use a full 20v battery and put a wire in negative and positive then do same for the one that won’t work but only tap the negative wire to the not working one for like 3 seconds then put it on charger
Tried a 12volt battery tender charger and 2 razor blades but got no spark. Put the blades in between another porter cable 20v and the Dewalt 20v and got spark. Back in business and working now.
Thanks for this as I was getting frustrated-great tip that worked well, just wondering why DeWalt don’t suggest a way to do this? Or even sell a gadget to send the 3 quick charging voltage into it.
It's crazy how much this works I have a 20v 6ah only used it about twice and it stopped working did this but I tapped it 3 times didint work tried charging it tried it again but this time I just held it on there till no more spark now it charging
I will NEVER but another Dewalt tool,,,Got a 500 tool sitting and they can't build a damn battery and charger that's works right,,,,WTFUCKKKKK...Extremely aggrivated
Worked for me. Used a 12v car battery charger and sparked it a few times. Fyi ...initially I tried it at 2 volts but it didn't work. Wonder what the science behind this is?
you dont need the box or receipt for warranty return through DeWalt. For future reference if the battery is less than 3 years old just get DeWalt to replace it.
Be Advised that these Flexvolt batteries have to be pushed all the way in before they will charge. I have had dewalt 20V for years and just recently got the FlexVolt 9AH batteries. They will charge on a regular 20 volt charger. However the 20 volt batteries have one click to start charging. The Flexvolts have to be pushed on until there is a click and the light starts blinking.
Thanks. This solved the problem with my brand new Dewalt batteries that were not charging. It seems strange that their manual doesn't explicitly mention the need for the second click.
I just successfully used a 5 year old 20v max (2ah) to jump a larger 3 year old 20v max (5ah). I used a thin 22gauge speaker wire. My experience has been that the battery’s tend to lose charge when the temp gets under 40. I think the cold temps just kill any remaining charge on already low batteries that haven’t been used in a while.
Yes. The temperature definitely effects a battery's charge. I keep my Paslode nailer batteries indoors for that exact reason. And yes you can use speaker wire or many other conductors to successfully do this.
What did you have the jumper cables hooked to? Maybe I missed when you said it. I'm in the same boat as you, I only have one DeWalt battery, but mine is the 60v 6amp Flexvolt. I have Bosch, Makita, and Ridgid batteries, but do not know if hooking to any of those would work; I'm assuming it would. I don't have a portable car battery charger. I have jumper cables though. Could I hook them to my car engine and jump the battery?
No. Don't do that. I didn't have jumper cables, it was a battery charger I was using. If you have other batteries (like makita) you can jump one battery to the other with speaker wire.
@@Isaiiahii just make sure to connect positive to positive negative to negative and just give it a tap. If you see a spark, you know you're getting good connection.
@@fixinstuff4374 Unfortunately this didn't work for me. It actually broke my Makita battery. I knew that was a risk going into it. This makes me never want to buy DeWalt again. I have a flexvolt skillsaw and flexvolt grinder that are useless unless DeWalt will replace the battery for me. I haven't heard back from them yet. I don't want to buy a new battery because it seems DeWalt has tons of issues with their batteries. I have 8 year old Bosch batteries that still work.
This shouldn't have broke your Makita unless you accidentally mixed up your pos/neg. But yes you shouldn't have to do this, and many Dewalt fans have swapped to Milwaukee.
What are your leads connected to and what voltage did you tap the battery with? I’m having the same problem you describe but I don’t wanna assume it’s a battery charger and if it is what setting is your box on. Thank you
This is a rare case if the battery was that low to be able to jump it. I would not recommend jumping the battery with a lead acid charger. You should use another battery of the same voltage or brand that is lithium ion underneath the 20 volts which that battery sits at 20 volts until it's activated in the tool at 60 volts. Also I would never ever charge that 64 battery of any type on the black 20 volt charger unless you don't want it to work on 60 volt tools. This was a huge flaw that you all did and their design so if you have 60 vtools and batteries only charge on their yellow charger otherwise eventually it will reprogram it and you will not be able to charge it on your 60 volt charger nor will it work on your 60v tools. Also I highly recommend using a voltmeter as you were tapping that battery because I'm not sure how you did that so easily because 12 volts or even 15 volts is not high enough to kick on the charger it typically needs to be 16.5 or higher.
My charger thinks my battery is full. Solid read light...dead battery. This jump trick almost works but then in charger I get on blinking light...the solid right after.

Cannot believe this worked, but it legit just fixed a 3 ah. I used a 4ah battery with razor blades to fix my 3ah. Thank you
Jumped my 60volt with a 20 volt and it is now charging..thank you!
Hey bud! What cable did you use? Was it regular speaker wires? I’m trying to jump my flex volt with a 20V battery but I can’t get it to charge lol
I use 2 razor blades
Got it but what did you connect to the razors? Thanks!
It does work with other DeWalt batteries. I literally just jumped a DBC203 using another DBC203 and spare wire I had laying around
I have the same weed eater, the battery stopped charging (the charger works, just not the battery for this!) Ty for this video I can finally get to work on my crazily over grown yard

The charger didn't work but the second battery trick did, Thanks a lot.
Well SOB…it worked! Thank you. Btw: didn’t have jumper cables. Used 2 metal clips and let them touch once which created the spark.
I used this trick on a 20v 2ah and it worked! Thank you.
Used my car to jump start my battery, worked perfectly thank you!
Wow it worked. I almost threw one away and was going to buy new ones. I used a 12v battery jump starter for about 5 seconds
Hey I just tried it with a walmart battery charger and it worked. Friggin sweet man. a 20v 5ah and a 60v 6ah.
Wow, just wow! The 2 battery videos were all I could find too. Thank you!!!!
I didn’t think it would actually work until I tried it and holy shit it worked!!
You’re life saver. It will work any jump start from 6v-12v. Thanks for your video 🙏

you dont need the box or receipt for warranty return through DeWalt. For future reference if the battery is less than 3 years old just get DeWalt to replace it.
The power stack battery doesn’t work with the battery jumper trick , completely dead , won’t charge.

Be Advised that these Flexvolt batteries have to be pushed all the way in before they will charge. I have had dewalt 20V for years and just recently got the FlexVolt 9AH batteries.

Can I just put the other end of the blades into the donor battery?
100% WORKS!!!!!!! THANK YOU SO VERY MUCH!!!!!
Just tried this and my flexvolt is now charging!!!! We'll se tomorrow if it works but it is definitely charging and refused to before.
Yeah. It actually work. Thanks bro.

Also I highly recommend using a voltmeter as you were tapping that battery because I'm not sure how you did that so easily because 12 volts or even 15 volts is not high enough to kick on the charger it typically needs to be 16.5 or higher.
What was the other end of the cables hooked to?
Thank you! I Did it and it worked. You are the man💯
My charger thinks my battery is full. Solid read light...dead battery. This jump trick almost works but then in charger I get on blinking light...the solid right after.
Mines doing the same any luck on a solution?
You just saved my butt! Thank you 😎👍
You are AWESOME thank you
