DEAD TOOL BATTERY JUMPSTART HACK - Ryobi, Dewalt, Milwaukee ⚡⚡⚡

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 :)

#KiteArmy 2021 how to fix and repair a Ryobi Milwuakee Dewalt EGO Toro Greenworks kobolt lipo battery

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!

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

[ronaldthornton]

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. 🤘🏾

Outstanding!! So much easier than other videos, I saved well over $100 using this video to save 5 dead, unchargable batteries!! Thank u sir!!!!

If you notice once you hook up to test the battery the second time (after the jump) its steadily dropping in 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.

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!

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!!!

[BXHiram]

Just saved two dewalts and one Worx, you are the man. Thank you!

[bharamas]

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 $1 for a feet of 14 gauge wire and 30 seconds to charge my dead battery. You saved me exactly 99$

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.

I had a brand new out of the box milwaukee battery that would charge so I grabbed a piece of romex hooked it to another one of my milwaukee batteries for 2 minutes and put it on the charger and it immediately started charging..this is a great hack

[rosseye]

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!

[thedeergarden]

Worked great. I only left it for about 30 seconds and tested it and was already good. Thanks!

I finally got to try this technic. Works BUT - If your battery has an issue, it will still have an issue. But it was fun to see it actually work to a point. AND OMG it was a Brand New Dead Worx battery. Came back to life but would not completely charge and would not hold a charge for very long. If used INSATANTLY it did go for about 5 minutes. Love Works and this was the ONLY Issue I have every had. Customer Service replaced it.
And Damn but I want a Pressure washer. Did they discontinue the short wand?

[OldGuyGarage-lq]

Wow! Totally works. I saved a Dewalt battery and a Black and Decker battery with this method. Thanks. Saved me a bunch $

[jaguiar]

3 years later it's still working. Thanks

[TrevorBengtsson]

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!
