Amazing what one can do with unlimited free time lol
Bhahaha yeah or no free time and an imagination my brother
Why be a jealous hater ….. go somewhere else
@@lawncuttingplusdelta I’m not jealous nor hating lol. It’s sarcasm. A salute to a multichannel content creator/ regenerative farmer/ builder/ repairman/ rebuilder that has time to discover something new. Relax.
@@kevindavis3841 awesome 👏 👍🏻…. Well said
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.
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.
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!!
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.
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 🇺🇸🦅🇺🇸
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.
What we're looking for starts at 2:42. I've got my jumper wires prepared. Gonna pause now and give this a try (Batoca car polisher 12V, 5Ah is completely discharged and will not charge, and I have another one that's fully charged)... ...10 seconds wouldn't do it. I heard somewhere else that it can take 20 minutes, so will try that...
Great tip and thank you for sharing!
Just tried this and it worked!!!
Awesome as always.Thanks for sharing and taking us along
oh my! thank you so much for this video. I was thinking earlier this morning what to do about my saw battery that won't charge. wow, just wow. I have not even googled it or anything yet. your vid... here it is.
You only have to use the positive and negative points for it to work
Haven't even seen this one LOVE subject matter
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
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….
Great tip
Josh so great idea 👍
It doesn't matter to brand or what tool it is. They're all just tools, and they're all good.
Keep up the good videos
I have some absolute TRASH tools… completely worthless
FALSE STATEMENT, there is a difference!!
...very useful info!!!😀
That's good to know, thanks for sharing.
Great video !! Thanks for the tip !!
Thanks Josh. I have three dead batteries myself. I love your videos. Philip from Charleston South Carolina. P.S. I’m praying for you and your wife. Heaven Father has a plan for you all.

Great content as always!
Wooo!! Thanks for sharing dude!
Josh if you use different color wire for each jumper that harness idea will work perfectly
requires 5 rolls of wire lol
@@StoneyRidgeFarmer or get 4 different colors of electrical tape and put a stripe on each end of the corresponding wire
Great tip Josh! Wooooo!
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...
Was excited to Fix my battery but only have the one
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
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!
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.
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?
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.
@@stubbshomestead1316 thank you I appreciate the insight
When cutting zip ties I’ve always a large toenail clipper. No sharp end. Jim80
this tool is perfect....tightens and clips my friend...but toenail clippers work in a pinch for sure lol...great idea for sure!
So I just tried to jump my Bosch battery, hooked up my dead 18v 4ah battery to a. Good 18v 8ah battery. Left them attached for 5 minutes. Battery says it has 10v, but it also got hot. As it cooled down, it’s now 4 v. still won’t charge either
Sending to my husband! 😁👍
I literally just threw a Briggs 82 volt .... dumpster dive to try this trick!
Do both batteries need to be of the same Voltage?
I'm not sure....but I would use 2 identical batteries...this isn't recommended by anyone fyi
The issue I have is the battery charges, but doesn't last long. Will this method work on that?
sounds like you may have an old or worn out battery...probably won't do anything for ya
typically, when a battery goes below the cutoff voltage (2v/ cell) there is a risk of permanent damage to the cell the longer it stays below the threshold. Sometimes it can be recovered, usually not really. A healthy cell will maintain a voltage of 4.20 for weeks if its just sitting un used, a damaged cell can be charged to 4.20v but you will see this voltage drop due to internal damage/shorts even if its just sitting unused.
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.
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.
Awesome
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
Hmm, were'd you learn that?
Honestly just had an idea bused to be an electrician
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.
How do you repair an old school DeWalt battery that is dead and won’t charge can you please make a video
Cool
👍
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 ?
Will that work for a Dewalt
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.
Can you jump a bad 20 volt dewalt battery with a good 20 volt dewalt battery like you did with millwalke
Josh, does the fix work on say Dewalt or Porters Cable batteries also?
i just do + and -
1:12 IMLMFAO!!!
These 1.2volt cells that are in there are EVERYWHERE!
They are SO hard NOT to come by!
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.
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.
PS, my DeWalt, batteries is approximately 15 years old
I didn't know that
Does it work for a dead DeWalt 20V battery too?
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.
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)
How do you fix the Dewalt battery?
Wow first viewer!
Different colour cables
if you used different colors for each of your jumper wires - you wouldnt have to be bundling them then cutting them back apart problem solved -
yep....you got 5 rolls of different color wire in your shop lol....I don't but hey..this works!
@@StoneyRidgeFarmer seriously? I can't imaging not having stuff like that available in my shop. after 20 years - I have accumulated all sorts of odds and ends - i have an "electrical box - all sorts of wire, meters solder guns left over bits and pieces - easy enough to just look through and pull out what you need -
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.
or I could label each wire
I have one that shows two bars and won’t charge, will it work on it it’s a two hundred dollar battery!!
Third viewer. I’d bet the battery was full.
I believe this only works for lithium batteries
Nope works on nicad I’m told
Just use different color wires lol or use different colored electrical tape on each pair of ends
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!
Why so angry with the anti American sentiment?
U don’t have to have that many wires you only need 2 wires
Which 2?
Second Viewer, lets go.
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
👍
