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.

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 just did this to 3 dead Dewalt batteries, and it freaking Thank you so much.

[georgelee]

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!

[MothmanViper]

Straight up worked. Used 20v DeWalt to awaken 20v Bosch for about 3 seconds. Charger blinking now! Ty.

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 !! 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.

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 YouTube

[mohamedsheik]

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.

[Mike-qlsz]

That's why the corded power tools will always rock!

[alyte]

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!

Have a Harbor-Freight 20v 5 ah battery that went dead from lack of use / charging (only used it once in the past two years)...charger lights would only flash...Didn't want to hunt down some solid wire...so I used 4 "t-pins" from my local fabric store inserted into the battery slots...(picked that idea up from the South Main Auto channel) and a pair of alligator jumper wires...got a spark upon touching the negative t-pin...so i sparked it again...immediately put the battery on the charger...IT IS NOW CHARGING!!!! In the words of Elvis: "Thankyouverymuccchh!"

[terukopops]

THANK YOU 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!

Literally the most useful YouTube video ever!!! Thank you sir!

[tarefoot]

Thanks my man, I just threw away a Hart battery the other day in the trash because it was dead and wouldn't charge at all. After watching your video today I went and got the battery out of the trash and hooked that battery up to another Hart battery and it worked just like your video. Very much appreciate what you showed.👍👍👍🙏

[Reality_Check]

I bought a Hart drill combo and the battery that came with it NEVER until I watched your video and used your technique. Flawless!! Thank you, sir

[StangCrazy]

Worked for my 18 volt lithium. Went from 2.3v measured to full charge 18v. Held the wires for about 15 seconds. Thank you!

[oldmarine]

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).

[skullrose]

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

[blakeharrup]

tried it . . . it 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.

[mrk]

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.
