Dead DeWalt Battery? Not charging?- TRY THIS- (it works! ...-usually)

[@joegut3fish]

This could have been a 30 second video

[@shoDOHC]

Make the video then

[@whiteflagrage]

Yeah but i would have missed a couple of laughs

[@nathanbaker5773]

That worked just fine Wasn't charging now it is 6ah flexvolt 20v. 60v Thank u

[@yousefalmarhoon8789]

If you have a DC power supply and multi meter, just open the battery & check the voltage of each side. I guess it has different voltage in each of the three packed sides connected together, I already fixed my Milwaukee 12AH battery with this method since one side was 3.5 and the other was 3.74 after equalizing them with 3.8V it started charging with zero problem, + I saw videos with guys fixing dewalt the same way on KZbin

[@eddygarcia7022]

J'ai le même problème avec les miennes mais je vois pas comment faire

[@kenibnanak5554]

There are size 18650 batteries inside that battery pack. There is probably only 1 of those needing replacement or resetting. All should work well then.

Read the Description ! He said "it Works , Usually" but you rather sit here and Criticize Him ! I have done many of these things before and it works sometimes, actually , Most of the time ! Don't Criticize the Guy !!!!

I have 3 of the same Flexvolt battery you have, one came with my chainsaw and I bought a package of two a month later...that was about 20 months ago. Now two of them charge perfectly and one...charger light blinks once then nothing. I have a charger in the garage and another in the house...same behavior. The battery is definitely seated just fine in the chargers, I do press the release button. I jumpstarted from one of the identical batteries...got one light to come on the battery but same behavior in the charger...one blink then nothing. I tried charging from a float-type 1.5amp automotive charger but it says it is already charged. Maybe I will try jumpstarting from one of my 4 and 5 amp batteries.

[@shoDOHC]

How frustrating this crap is. Let us know if you find a solution

[@dakotacarter3489]

So this has been happening a lot with this exact battery. I have a few of the flexvolt 9ah batteries and also the same exact charger. I thought the same thing you thought when i bought the batteries recently. I was actually about to take them back. I know it’s hard to believe but you actually aren’t seating the battery correctly. Yes, you are fully seating it. But for this battery, due to the size and weight, when you force it into the charger without fully depressing the release it makes a connection before it is fully seated and in my case it would show the battery was fully charged on the charger, even though it was nearly dead. You have to fully depress the release, and i mean fully, all the way until the battery is fully seated and then release, and it should charge. Again, i know your fully seating it but i can tell in the video you are not depressing the release fully, and although what you’re doing works for literally any other battery they make, this particular one is picky about how it is connected to the charger. Mine did what yours is doing right out of the box, before ever being used at all, and it was all because of not fully depressing the release button until fully seated

[@shoDOHC]

Very interesting stuff. Thanks a bunch I will give this a shot!

[@dakotacarter3489]

@@shoDOHC let me know if it works. I actually was about to do the same thing you did as i have done it before, and i came across another video and tried what i just explained above. Hope it works out for you my friend. These flexvolt batteries are far too expensive to have issues

[@shoDOHC]

@Dakota Carter hell yeah! I'll get back hopefully it's not been too long!

[@uceniculluiyahushuahamashy6251]

Друг, это никак не работает, купил новую зарядку 118 и новый flexvolt 6ah, не заряжается, другая батарея всё ok. Попробовал как угодно нажать, изо всех сил нажать, никак не хочет заряжаться... 😢😢

[@TroyHelmly]

I don't think this is the problem. It doesn't take much for the prongs to make contact. Every other battery I have is seating the exact same way and they all work fine. This is more than likely an internal issue

[@NTSRFR4]

It would be nice of Craftsman had the designations of what polarity's and what not each of the terminals were on the 60 volt, but mine doesn't show anything like that.

[@shoDOHC]

That does suck..time to bust out the DVOM

[@JT_70]

Perhaps you drained the tiny charge by continuously pressing the status button on the battery. The %charge light seemed to have gone out before you took your finger off the status button and plugged it into the charger.

[@shoDOHC]

Interesting. I should re-run the test and see what comes of it..we gotta solve this problem

[@JT_70]

@@shoDOHC What size lithium cells are inside the DeWalt batteries? They are about Samsungs about 2x the size of an 18650 and have a cap on one end.

[@Foxbodychuck386]

It didn't work for me either. Mine did the same thing I jumped it and 1 bar on the battery would light up but it still wouldn't charge. I only used mine a handful of times before this happened.

[@julianjulio3690]

El cargador no es el indicado para cargar la batería FlexVolt, puede usar un DCB116

[@addminusDIY]

Same happen to my flex volt 6ah, good thing its from garage sale, didn’t cost me much but done all the stuff and still didn’t charge. I went thru all videos of battery fix for dewal haha

[@Brad-0212]

The wires you used are a little to thin for the power your using if you use more bigger wire so it doesn’t get to warm or over heat also maybe try out the wires on the battery again for around 1/2 mins sounds quite a long time but it should hopefully juice it enough for the charger to recognise it but honestly the price of that battery I’d say your right with price around £200/£300 wouldn’t pay it if I’m honest good video tho lol 😂🤣

[@tbabicas]

I used thin headphones wires and it worked for my 54v 6amp battery lol only 3 seconds did like electricity shock.

[@Alphasig336]

I use 14 Ga solid electrical wiring

[@whiteflagrage]

Size of the wires will not be the problem.

[@Brad-0212]

@@whiteflagrage probs cell balance or faulty cells could be anything but only way to find out with these batteries is take apart and test each cell

[@whiteflagrage]

@@Brad-0212 yep I think you're getting close to solving it

[@AjManiclang]

Can do 72v good battery kicker to 36v dead battery tnx

[@shoDOHC]

It should really be ok. Keep in mind how the charger is just looking for a vase voltage so it's really a pre-screen

[@shoDOHC]

Eh em....BASE voltage

[@kbguy9654]

Isn't that charger 12 and 20v only?

[@shoDOHC]

They are 20v batteries

[@whiteflagrage]

Its 3 batteries in one case

[@tbabicas]

It works bro 🎉😮

[@shoDOHC]

Hell yeah. Glad the vid helped ya

[@jonasbarry8979]

Take 5 seconds and solder tabs on the wires

[@shoDOHC]

It's a male and female connection. Why would you solder that if it's not permanent. This is only to jump a battery.

[@whiteflagrage]

No soldering irons at that garage sale?

[@shoDOHC]

@whiteflagrage3840 yeah they had 4. I bought all 6 of them

[@juanleon213]

Can some one tell how i can fix it please

[@shoDOHC]

Unfortunately it can vary case by case. But TYPICALLY it's a low-no voltage issue that causes the charger to "not see" the battery. What I can tell you is to at least try jumping it, them go from there- fusable links, dead cells and so forth

Here's why you sound like an absolute pretentious clown. Any real mechanic knows that a collection of tools one has isn't some mega collection that daddy magically gave you. You find most a few at a time over decades. Much like my incredibly usefull and powerful husky ratchet and klein strippers, they are part of a real collection of tools that I earned. If you wana be some dickfake fanboy little kid about a specific brand, go ahead knock that tiny brain out. You're the exact type of maliable target all those brand hope so bad that they'll hook in the ass. All you. Congratulations boomer.
