HOLY CRAP! Mine was so dead that it wasn't even flashing at all when I hit the button. I didn't think it would work because of that, but it did! Saved me a lot of money man thank you for sharing!
Buddy… you are a blessing disguised as one smart human… been trying to find a receipt for this battery all day and then came across this video and fixed it in 15 seconds. Jump starting Kobalt batteries…. Who would of thought!!! Thanks pal!!!
So I bought a Snowjoe 96v 2 stage snow blower last year. Went to use this year and all 4 batteries wouldn't take a charge. Jumped them with a Harbor Freight 20v battery. All 4 charged when put on the charger saving me a huge expense on a year old machine. Great video and Thank You!
I just want to say thank you, because my husband and I almost took the battery back, thinking that it was bad, your idea worked like a charm. Thank you so much.
I was a little hesitant at first to try your method. But, to my surprise it worked! I was able to charge the dead battery fully. Once again thanks for the solution for my dead battery.
Succussefly Jumped My Lawnmower Battery. I have the Kobalt 80v 5.0Ah battery for my lawn mower and it refused to charge after a year so I threw it in a drawer for another year forgetting about the warranty. Just saw this video and I used two 80v 2.5Ah batteries to jump this one 5.0Ah battery and it worked!!!! It's now taking charge. You rock!!!
I just did this and it worked. Thank you so much. I put the battery in the charger and at first the light didn't come on. Then all of a sudden the charging light started flashing green. Amazing!
WOW!! You sir, are a blessing to society. IT WORKS!! New Kobalt Ultimate Output 4ah battery. Plugged into charger, nothing but a solid green light (no blink), no charge. After 1 hour, nothing. Searched and found your video. Jumped from a Skil 20v 2ah battery for 30, then 40 seconds. Plugged Kobalt back into it’s charger….blinking green light and taking a charge!! THANK YOU, THANK YOU for posting this video.
If all cells have just drained too low, then this can work as long as the cells aren't damaged. This can be rather dangerous if you don't check to make sure one of the cells hasn't dropped. If 1 cell is damaged and is at very low voltage and can't charge at all, You could overcharge the other cells, Lithium cells can catch fire overcharging them. The safe thing to do is to unscrew the bolts, and use a volt meter to check each cell to make sure they are all somewhat close to each other. If you find all of them at 3.9v for example, but one of them is 0.2v for example. Do not do this method as one of the cells has faulted or shorted. When that happens, I wait for 2 bad batteries and then sacrifice one of the cells from one and replace it in the other. Just have to be very careful doing that and requires hacking at the enclosure to do it.
Same exact scenario - brand new and it was flashing red. Battery was manufactured on 04/24 and today is 09/24, so not even 6 months on the shelf. Did this for about 15 seconds following similar procedures as jumping a car battery (red to dead, red to donor, black to donor, black to dead) and all is working now. Thanks for the advice!
Thank you!! This worked. I had a Greenworks 80v battery that I didn’t use for a year. So then I did your method with another 80v Kobalt battery. I left it for like 5 minutes and it’s charging now!!
Genius, it worked for my 80v Kobalt leaf blower battery. Used it outside in the cold and battery died will using. Could not recharge cause charger kept flashing red even after letting it sit at room temperature for days. This method saved my battery, though I had to let the 2 batteries connected for a good 30 minutes ( probably because of the size of the battery. Thanks again!
Great tip! I thought my Kobalt 40v battery/charger was dead but your suggestion allowed me to get the battery recognized by the charger. Let it charge overnight and the next day it was like new.
Holy Smokes! Worked like a charm!!! In my case, I could not get any of the 4 lights to come up...100% dead as a door nail....I used actual wire (just what I had on hand) and left them hooked up for about 30 seconds...and then it worked! STELLAR WORK HOMIE
It works! I did it for a few seconds and it wasn’t enough. Then did it again for 10 seconds or so and it had a little flash fire. I tht ‘o well it was dead anyways’ To my surprise, it had some juice. Kobalt brand
Wow! I just bought a charger with 2 battery bundle. One battery charged, and the other wouldn't. I took it back to Lowe's and got a replacement. But the replacement also made the charger flash red. I did what you show here, and it worked like a charm.
I had the same problem on a kobalt 24v battery that came with reciprocating saw I bought off marketplace. Jumped it like u did, it worked. Now has and maintains full charge.
While I don't currently have some spare wire to do this to a battery I know works cause I used it a few days ago, but forgot to take it off a air compressor, I appreciate this tip and will use it at my earliest opportunity, thank you in advance!
Thank you so much!!!! It worked perfectly!!! Only took. Minute or so I used old speaker plugs cut off the ends stripped the wire and like magic I’m back in business!!!!!
You, Sir, are the man! I just bought the double 4ah battery with a free tool, and after an hour of charging, the first battery I charged did not work. I was mad because now I had to make another trip back to Lowes. Then I figured I'd look for solutions on UA-cam and saw your video. I just thought I'd give it a try before going to Lowes, and lo and behold; IT'S ALIVE! LOL. Thanks for the tip!
Thanks a ton, this trick even worked using 56v to fix a dead 80v. Since I metered the 80v dropped to 37V😂. The battery light didn't turn on, but after a min or two the charger is now charging it.
I can’t thank you enough! I threw the battery in the trash, but now I can go ahead and get that bad boy back out and try this! I was so confused because I’ve had it less than a year and only used it a few times in a hedge trimmer lol. You are a life saver-er battery saver?! 😂❤
I tried that with my Milwaukee 12 amp battery and it didn’t really work, I was able to get a full charge but the battery only last 10 minutes 🤷🏼♂️. Have a great one Lucas 🙋🏼♂️🙂👍🏻
YOU'RE THE MAN!!!!! I purchased a used battery at an auction for cheap. When I got it home it just flashed red in the charger. I did your trick by jumping the batteries and now it works. I was almost going to throw it away, but now it works!! If I know where you are I would buy you a beer!! Thanks!! P.S. What do you do if you don't have a second battery? LOL
WOOHOO!!! You saved the day! Or, well, you saved the BATTERY!!! LOL! We were about to throw the battery out and decided to search UA-cam and luckily we found your video. This worked like a champ and in just a couple minutes we have the battery now charging properly. Thank you!!! Subscribing to your channel to see what else you can help with!! :-D
Ok so I drive a semi. I use the 40v blower on the daily. Came to watch the video for help. Only problem is I don't have a second battery or wire. What I did to get mine back to running was put battery back in cradle and turn the inverter directly off and back on and it jolted it back to life.
I have a 24V 4AH battery that’s rarely been used. I got it last year or two years ago at most, it came with the blower. It works when it wants to, but often all four lights on the battery flash at the same time for quite awhile. When I charge it the charger flashes green like it’s charging for a couple seconds and then goes solid green like it’s fully charged. However when you press the button to check the battery level it again flashes all four lights red at the same time and only works when it wants to.
Thank you. I was about to go buy another battery again. I got 4. What's your method. I am able to charge all of them. You should go work part time at lowes.😂😂😂To help the customers like myself.
Every UA-camr gives the exact same solution which is just great if you have TWO batteries. What are you supposed to do if you only have ONE? Or what if you have a second battery but it's less voltage than the one you're trying to get up to charge so your charger will recognize it?
I've got a different issue and it seems to be exclusive to the high output batteries. They won't charge unless they're down to one bar. Idk if the older chargers don't read them correctly or what. And not long after the four amp ultimate output refused to charge above two bars. My regular ones charge fine . Have three ultimate output and they're all doing it.
Thanks for the info i have a 80 volt max kobalt battery that will not charge so i am going to try this tomorrow and hope it works for me because I done bought to new charges thinking that was my problem and it wasn't so i sure do hope this works for me
I have a bad kobalt charger, so I will gut it and add a mechanical timer and a wall wart power supply. Just install the battery and turn on the timer to bring it up a it. Since it is a slow low voltage charge one can leave in on longer like 15 minutes. I"ll just need to decide with a dc amp meter what size fuse I'll use. Use a slow blow at about 10% higher than the initial spike.
Wish this worked for me. Tire Inflator drainied mine dead. This will get it to all 4 green lights flashing, but won't ever start to where it will take a charge.
The problem with mine is, is that my battery charger will flash green as if its charginging one of my batteries, but it will flash maybe 4 times then fully illuminate as if the baterry is already charged. The battery never has mor than one green bar on it.
My comment is not on charging but FYI. If battery starts flashing and drill or impact won't work unless re- inserting battery then I found letting switch snap back to off stops the problem.
Mine take charge for a bit, light is green showing is fully charge on charger, but only one light on battery shows that needs more charge. So mine does take charge but it doesn't charge all the way. Will this method help?
Thanks! Got a battery with a tool deal, and then saw it was a pretty old manufacturing date. Then it started having trouble in the cold to recharge, then it just wouldn't. A few seconds jump and the charger was OK to charge it. Hopefully I can squeeze some more value out of this battery before it totally dies. Maybe I'll label these and stop using them when there's 1 bar remaining.
Thanks for the video, I have a new battery , that I have only charged once , it got stuck on on in my tool box in my Jeep and killed the battery ? My question is I only have one kobalt battery if I try this cam I do it from a lower volt battery from my craftsman batteries ?
I've got 2 batteries that wont take a charge and the charger shows green as if they are charged. Can't figure out how to charge them besides jumping them to another battery. any advice for this problem. They are 4ah ultimate output batteries with somewhere over 22v in them. if i jump them to a good battery they will indicate 1 led of charge and run tools briefly. no matter what i do they show green on the charger.
I did this for my 40V battery for my Mower. All bars shows on the gauge when hooked up to the good battery... but soon as I unhook it will not charge (charging light does not come on) and the light in the battery doesnt gauge come on. Any thoughts?
My Kobalt 24v battery does charge and is green. But the problem is when I plug that Kobalt battery into the Kobalt 24v tools, the tools do not power up. Is there any way to fix it? Thanks.
No go for me, fried the good battery I used for the jump. It won't even flash now. Bad one will still flash. 24v. kobalt black. Now down 2. These were my newest batteries[ 2020] . I have a half dozen regular blue 2.0 & 4.0 that are 6 years old & work fine... Still love my kobalt tools though .
In my case it does flash as if is fully charged just solid green light, but when u click on the battery it does display as only 1 bar left , would doing this fix that issue ?
Did like you said hooked up 2 wires from my dewalt battery to the Kobalt 40v..after 2 minutes I was able to charge the Kobalt battery... Thank you..
HOLY CRAP! Mine was so dead that it wasn't even flashing at all when I hit the button. I didn't think it would work because of that, but it did! Saved me a lot of money man thank you for sharing!
This worked like a charm with my 80v batteries too. Saved me $200 on a replacement!!
Man, I spent a bit of a time and was getting frustrated but tried this on my Kobalt 80v and it worked like a charm!
Buddy… you are a blessing disguised as one smart human… been trying to find a receipt for this battery all day and then came across this video and fixed it in 15 seconds. Jump starting Kobalt batteries…. Who would of thought!!! Thanks pal!!!

Been charging my kobalt for 2 days and yes the charger red light stayed flashing. Watched this and man I Preciate it. Very helpful advice here.

This worked for me on my Kobalt 40V MAX 2.5Ah battery. Preventing me from handing over my $150.00 to Lowes :) Thank you for this easy and helpful tip
Thank you thank you and thank you! Worked! Left a battery on a tire inflator and it was drained too far to register on the charger!
The Tire Inflator killed mine as well. Unfortunately, this one couldn't revive mine.
I have a SnowJoe 24v thought I had a bad battery. Contacted CS while waiting for a response I found this video. Worked like a charm!!! Thanks bro!!

This works (assuming your battery is dead and not broken), thanks man!
Thank you so much just jumped my brand new battery. Saved me a trip from returning it

Wow, thank you! Worked immediately after giving it a jolt!
Thanks for the video! I ran a brand new battery dead and it wouldn’t charge. It’s charging now thanks to you.
Glad it helped
You just saved me from a headache and some penny. Thank you!
Was going to thrown the battery away but came across this video.
Thank you!!
Awesome!

Thanks for this. I'd looked at several videos and this is the one that worked!
Thanks for the video. Saved my battery and $60 bucks
That's interesting! Good tip Lucas. 👍
Thanks!
Thank you this was very helpful .👏🏽by the way who gave you that shiner?
Thanks for the help! I couldn"t help noticing your Greenup County license plates!! Hello from Ashland!
Right on! 👊
Worked great on 2 batteries! Thanks!
Was going to bring a new 2 battery kit back... thank you man!
Thanks! Just saved me a trip to Lowe’s!
👊
I tried that with my Milwaukee 12 amp battery and it didn’t really work, I was able to get a full charge but the battery only last 10 minutes 🤷🏼♂️. Have a great one Lucas 🙋🏼♂️🙂👍🏻
Interesting! So far so good on mine. Maybe because it was a new battery already. 🤷🏼♂️
It worked!!! You, my man are awesome. Thank you so much for posting this video.
Right on!
Awesome. Worked like a charm with 14ga speaker wire
For anyone watching this. It is worth a try. I just jumped mine. This can definitely work
YOU'RE THE MAN!!!!! I purchased a used battery at an auction for cheap. When I got it home it just flashed red in the charger. I did your trick by jumping the batteries and now it works. I was almost going to throw it away, but now it works!! If I know where you are I would buy you a beer!! Thanks!!
P.S. What do you do if you don't have a second battery? LOL
You’re welcome! I don’t exactly know, but I would think if you had a cord that produces 24 volts that would work too.
Wow! So easy and I have 2 good batteries again. Thank you, thank you.
just now did this and i think the battery is gonna charge, thanks for the trick
Good deal! Glad it helped!
Thank you! That worked exactly as you said it would!
Great video! Saved me from buying a new battery. Thanks
Worked !! Awesome. Thank you for a helpful video.

Thanks bro was gonna have to go to lowes and trade it in great content 👌 💪💯
Simple and great, one quick question, I do not have second Kobalt battery , I have Dewalt or Ryobi batteries , can one of those be used to jump start
They should work the same
Thanks for the info i have a 80 volt max kobalt battery that will not charge so i am going to try this tomorrow and hope it works for me because I done bought to new charges thinking that was my problem and it wasn't so i sure do hope this works for me

If that method doesn't work, you might have to open up the battery pack and charge the cells which are more discharged more than the other cells.
THE BEST, MAN!!
It worked ! thank you!! I got a new one that didn't work as well
Good deal, glad it helped!
Thank you for the information!
That worked amazing! Thank you . I just subscribed
You are a life saver brother you honestly saved me about 900
Thank you 🎉🎉🎉🎉 worked like a charm.
Wish this worked for me. Tire Inflator drainied mine dead. This will get it to all 4 green lights flashing, but won't ever start to where it will take a charge.

That's good information to know!! How do you know all that stuff? God Bless!!
Lol. Well, mostly just trying stuff! And UA-cam…😂
My comment is not on charging but FYI. If battery starts flashing and drill or impact won't work unless re- inserting battery then I found letting switch snap back to off stops the problem.
Good info!
Here’s what you really do. Buy the same battery from Lowe’s. Return it with the bad battery a day later with your receipt.
Mine take charge for a bit, light is green showing is fully charge on charger, but only one light on battery shows that needs more charge. So mine does take charge but it doesn't charge all the way. Will this method help?
Thanks! Got a battery with a tool deal, and then saw it was a pretty old manufacturing date. Then it started having trouble in the cold to recharge, then it just wouldn't.

Maybe I'll label these and stop using them when there's 1 bar remaining.
That’s probably a good idea. 👍
Thanks for the video, I have a new battery , that I have only charged once , it got stuck on on in my tool box in my Jeep and killed the battery ? My question is I only have one kobalt battery if I try this cam I do it from a lower volt battery from my craftsman batteries ?
I believe it would still work…
I've got 2 batteries that wont take a charge and the charger shows green as if they are charged. Can't figure out how to charge them besides jumping them to another battery. any advice for this problem. They are 4ah ultimate output batteries with somewhere over 22v in them. if i jump them to a good battery they will indicate 1 led of charge and run tools briefly. no matter what i do they show green on the charger.
The only idea I have is do you have multiple chargers? I wonder if it might be an issue with the charger…
I have this same problem and it doesn’t matter what charger I use still trying to figure it out
Mine will flash green 3 times then just not kick on. Thank you in advance if you get this and have any ideas that will help
I did this for my 40V battery for my Mower. All bars shows on the gauge when hooked up to the good battery... but soon as I unhook it will not charge (charging light does not come on) and the light in the battery doesnt gauge come on. Any thoughts?
Thank you for this video!!
I tried this with a 40v battery i bought last summer. It won't take a charge. Battery level light. All of them blink. Not sure what that means.
Thanks for the tip! Is this ok to do with an 80v? I'm having same problem and want to try this.
It should work the same, but I can’t say for certain.
@@PeeksPeakHobbyHomestead Thanks!
I got one red cell when I push the battery life button and NO lights turning on when I connect it to the charger, so I guess my charger is broken?
My Kobalt 24v battery does charge and is green. But the problem is when I plug that Kobalt battery into the Kobalt 24v tools, the tools do not power up. Is there any way to fix it? Thanks.
I’m sorry, but I do not know what that would be.
Thank you! Problem solved.
No go for me, fried the good battery I used for the jump. It won't even flash now. Bad one will still flash. 24v. kobalt black. Now down 2. These were my newest batteries[ 2020] . I have a half dozen regular blue 2.0 & 4.0 that are 6 years old & work fine... Still love my kobalt tools though .
Thanks about to try today
In my case it does flash as if is fully charged just solid green light, but when u click on the battery it does display as only 1 bar left , would doing this fix that issue ?
I really don’t know, but I don’t know what it would hurt to try…
I have this same problem
i have 3 and they do this as well. what can i use instead to do the trick. brand new as well.
