For those wondering, the battery is not actually bad it's just dropped below the low voltage threshold that will turn the charger on. This is part of the computer charge controller he mentioned. It has something to do with these batteries being. A fire risk if taken too low or charged from too low of voltage or something. I would not recommend leaving batteries in attended charging no matter if you do this or not.

You could make a harness out of 5 core trailer wiring. Red, green, white, yellow & brown coloured wires so it’s easily identifiable when hooking up in order.

[@msrockwood]

Bravo! Most useful and brilliant idea I’ve seen in a while. Was going to call Milwaukee over this same problem but I am going with this. Thank you so much!!

[@williamhightower4940]

Speaking of tagging when you put the battery into service I would also tag the battery that you have done this trick too. That way if there seems to be a premature failure you'll know if there might be a contributing factor.

[@charleswise5570]

Josh, if you have a label maker, just put a label on each end of each wire with a # 1, #2, so on, and so forth. If you have different colored stickers, that would work also. Same color on each end of the wire.

Amazing demo!!! I’ve heard rumors of that working but haven’t had a demo like that to feel confident enough to do it. Thank you 🇺🇸🦅🇺🇸

[@standzierzega9049]

Great tip and thank you for sharing!

[@JimsEquipmentShed]

I bought the dewalt adapter as soon as it came out. It took me a couple of iterations before I realized that the adapter was the reason the batteries were dying. I always used to leave my 18v batteries on my drill, and never thought another thing about it. In the end, I ended up just getting rid of my dewalt kit, and switched to makita. (Makita batteries suck, but at least they are marginally better.) I wish I had made the move to milwalkie instead….

[@jonpaulandrews3773]

I have the same Milwaukee problem. I just unplug the charger slide the battery on the charger than plug it in. Always works 4 me every time.

Thats awesome Josh i have a set of Kobalt 12 volt batteries went dead n wont recharge they dont make them any more said i woild have to buy 20 volt its a shame you get a new set of tools then they quit making the batteries for them thanks for the info i will try it have a great day on the farm

[@gafgradingllc5424]

It doesn't matter to brand or what tool it is. They're all just tools, and they're all good.

Sending to my husband! 😁👍

[@No1Bigbear]

It's the same principle/ problem that new automatic car battery chargers have...the charger has to see voltage in the battery before it will charge at all...great tip tho...pick the older battery chargers up at garage sales and keep it under your workbench for your car batteries...

[@jameskennedy673]

When I get though using my cordless power tools for the day I always take out the batteries. I was given two DeWalt 18V 6.5” circular saws with batteries and charger, one battery was dead the other almost. I priced a new battery $109.00, I ordered two adapters from Lowe’s for less than $100.00, I already had 20V lithium batteries plus I also found out that the adapter is hard to remove so I just leave them in the saws just remove the batteries.

[@TheBigmark75]

Josh if you use different color wire for each jumper that harness idea will work perfectly

[@StoneyRidgeFarmer]

requires 5 rolls of wire lol

[@TheBigmark75]

@@StoneyRidgeFarmer or get 4 different colors of electrical tape and put a stripe on each end of the corresponding wire

[@ryanjames8888]

Was excited to Fix my battery but only have the one

[@chrismcrae4652]

U pointed out all the reasons I don't use Milwaukie, never in 30 years from the 12v to the 20v Dewalt never had any of those issues, I still have a Dewalt 12 drill, I just buy replacment packs for the housing

[@StoneyRidgeFarmer]

12v? You mean 18V? FYI there are at least 30 comments asking if this works on DeWalt...it happens to every brand battery ....Milwaukee is awesome stuff my friend!

[@markschwerin1794]

Awesome

[@simondavis3434]

WOW, talk about bizarre... Just last night, I was curious of the name of the wood stoves that you collect so, I did some searching through your videos and found the video of when you installed the new rope seal on a stove. You actually mentioned this DeWalt adapter. I had never heard of such a thing and liked the idea. That video was many years ago and then tonight you mention it again. Crazy timing. So, BTW, what is the brand of wood stoves you like? I'm hoping to see you do a restoration soon. My apologies for the long comment.

[@Angry_Bob]

I think that was the Milwaukee fast charger. I’ve always heard it’s best to slow charge batteries, for the longevity of the battery.

[@scottsmith6846]

Hey Josh thank you for the video but I have seen somebody do this before in the past but I do have a question for you because my friend wants to get a circular saw a new one and I think the Milwaukee is going to last longer with the battery life then the DeWalt what do you thank because you have both woo

[@phillymet]

I just got home from work saw your video and Josh I have to say that is super cool. I wish I knew about that before I chucked out my old 18 V batteries. I bought two new ones and I’ll be sure to use this tip. Question: can you do the same thing with the 20 V batteries?

[@stubbshomestead1316]

This will work with any of the tool batteries. Just be careful of how your doing it, It can start a fire if done wrong.

[@phillymet]

@@stubbshomestead1316 thank you I appreciate the insight

[@Profshinobi]

Do both batteries need to be of the same Voltage?

[@StoneyRidgeFarmer]

I'm not sure....but I would use 2 identical batteries...this isn't recommended by anyone fyi

[@neuroradguy]

Cool

[@samfosdick9874]

I literally just threw a Briggs 82 volt .... dumpster dive to try this trick!

[@jamessteffens8337]

When cutting zip ties I’ve always a large toenail clipper. No sharp end. Jim80

[@StoneyRidgeFarmer]

this tool is perfect....tightens and clips my friend...but toenail clippers work in a pinch for sure lol...great idea for sure!

[@brandonbowser5487]

wonder if this would work on the ego batterys that wont charge or a koblt 40v that hasnt been chagred for a while ? any input ?

[@ronblack7870]

this only works on some batteries. it won't work on worn out batteries. i have a bunch of worn out 20 v dewalts that i have tried this on and most of them it did NOT work. and those 18v to 20 v adapters also burn up on any tool that takes real power like an angle grinder or big drill especially under sustained load. we use a bunch of dewalt drills in my factory , that's how i know this.

[@markcroucher3977]

Josh, does the fix work on say Dewalt or Porters Cable batteries also?

[@ClickinChicken]

Hmm, were'd you learn that?

[@StoneyRidgeFarmer]

Honestly just had an idea bused to be an electrician

[@natevanlandingham1945]

You have to do the same thing with smart battery chargers and car, golf cart, or deep cycle batteries. If they drop below a certain voltage the chargers won't recognize the battery and won't even cut on. The cheat is to hook another battery up in parallel like this to booster the voltage so the charger will kick off or get an old school manual charger and charge each battery for a bit to boost the voltage till the smart charger will kick on and take it to fill charge.

[@josephklingshirn7818]

Wow first viewer!

[@GhostEric813]

How do you repair an old school DeWalt battery that is dead and won’t charge can you please make a video

[@rockymatthews8643]

I didn't know that

[@ernieimbody7093]

Can you jump a bad 20 volt dewalt battery with a good 20 volt dewalt battery like you did with millwalke

[@TerrorTubbie666]

1:12 IMLMFAO!!! These 1.2volt cells that are in there are EVERYWHERE! They are SO hard NOT to come by!

[@patrickwiklund2039]

👍

[@kevinhitchcock7062]

Will that work for a Dewalt

[@ActionJackson2360]

I was able to put a changed battery in my ryobi charger then quickly change it back to the dead one, and that seemed to work.

[@michaelbrowne8068]

Same thing with battery packs , boosters or jumpers and new smart chargers. They won’t charge a dead battery. You use another battery to start the charge process and then they will charge. Not sure if the word is correct but excitation.

[@tonymcveigh8789]

Different colour cables

[@genecarr4568]

Does it work for a dead DeWalt 20V battery too?

[@davidj.kester7979]

i just do + and -

[@davidgenthnerjr4995]

I got a DeWalt 18v battery that no longer will take a charge and makes an audiable whistling sound if you try and plug it in. Guess its time to do away with the 18v stuff and breakdown to pay for the adapter and 3-20 volt batteries. Also I need to find out if those NiCad batteries can be thrown in the trash or if there is a special receptical I need to put these in.

[@StoneyRidgeFarmer]

check this link from my amazon page....you can still get 18v amzn.to/3sPCixn (don't buy the knockoffs...they are not as good)

[@bobbydee1187]

Third viewer. I’d bet the battery was full.

[@jimmeyer777]

How do you fix the Dewalt battery?

[@ivansharp6054]

I have one that shows two bars and won’t charge, will it work on it it’s a two hundred dollar battery!!

[@natevanlandingham1945]

When you wire tied all those wires together with same color and same color ends I was like no way he can sort those out to go to the correct slots😂😂. Then you cut it apart realizing the same thing.

[@StoneyRidgeFarmer]

or I could label each wire

[@GhostEric813]

PS, my DeWalt, batteries is approximately 15 years old

[@Toast3dAlmond]

Second Viewer, lets go.

[@cryptonym123]

Just use different color wires lol or use different colored electrical tape on each pair of ends

[@robbypelfrey7677]

I believe this only works for lithium batteries

[@StoneyRidgeFarmer]

Nope works on nicad I’m told

[@TerrorTubbie666]

2:07 LOL! I got a Makita 18volt drill laying around here, being used for 5 minutes in the past 4,5years (due to circumstances I shall not bother you with). I bet both batteries (1 on the drill and 1 loose one) are still full. You wanna know how I can be so sure of that??? Because it's a MAKITA, NOT made-in-usa-crap!

[@samfosdick9874]

Why so angry with the anti American sentiment?

[@mattive6212]

U don’t have to have that many wires you only need 2 wires

[@samfosdick9874]

Which 2?

[@darrenhenderson7076]

Be very careful doing this any tips touch it will get red hot and melt plastic off wires and then u gatta grab it with hands r hopefully u got something to grab it with this is really not worth the risk but Milwaukee batteries r really over priced they all r really
