Internet " you can't solder on cells" Me "been there done that"
A common 18650 Max operating Temp is 75C/167F That's hotter than you can hold and is common after heavy use(I've personally tested it). Soldering tabs on generally only gets to the barely warm phase. True solder doesn't melt until 375F but spot weld needs to be at least 2550F to bond. The spot weld is a second long. The solder is 7 seconds long. Just so happens 2550F is 7times more than 375F..... Go figure.

Did you notice that the failure battery is always the 1st one in the series. This is due to overcharging, the chemicals in the battery overheat and degrade. Its common in all batteries including phones. Very instructive video. Kudos.
how so even in phones ? phones are single cell batteries ...
actually, my own experience was the one/s in from the end that went more often.
I have had the best experience so far with the repair of Milwaukee M18 batteries. Out of more than 20 repaired batteries, only one had a faulty pcb board.
Great info! I have several packs that the BMS failed. The cells are still good but the little circuit board inside is bad. I take the cells out of those and use them as replacements as needed.
Awesome.
Amazingly informative!! You are one hands-on dude with zero BS 👍🏻
Even if I don't have a need for a pack, I harvest the cells and convert everything I have to use the 18650's I've done maglites air and water pumps, a lighted collar for the dog, anything I can fit them into.. just pay attention to the voltage...
I got 2 Chinese makita batteries for $32 from ebay they lasted a few months both shorted out with high amp draw tools. They sent me 2 new ones and the same thing happened .I bought some decent new cells from the 18650 battery store for $2 each and rebuilt them and they are amazing way better then any factory makita pack
Awesome
First off: Give Ginger another biscuit.
I had similarly the same issue with solar-powered lights. The solar panel was tested and it was putting out the needed voltage to keep the batteries charged, so I figured it had to be the batteries not accepting the charge. I went and ordered a 10-pack of matching batteries because I had 3 of these same lights. I tested the batteries on each one just like you did. I disassembled them because the new batteries cost me around $15.00 for ten of them and each light cost over $40.00 new a few years ago, so the expense was worth it.
Once I disconnected the old batteries that showed no power and soldered in new ones I saved 3 lights from the dump.
By the way, those 3 solar lights went almost 3 years without a problem, so hopefully, the new batteries will last just as long. I think it took about an hour to repair each one (disassembly was a headache), but well worth it as they live again and it didn't cost me another $150.00+ (Current Prices) to replace the lights. I still have 6 batteries left over, but it was cheaper to buy them in quantities of ten than one at a time.
P.S. I don't throw anything away intact. If I can recover a screw, bolt, washer, etc. from it, I do. This has saved me many trips to the hardware store when building something totally different.
That's great. Some people get enjoyment out of fixing, learning and saving money. The rest only get enjoyment out of shinny new and spending money, which is a never ending battle.
Love your videos man. Appreciate your no nonsense approach. PS: Your dog is a welcome addition to your videos. Makes them that much more entertaining. 👍🏻
I have to say I rarely find a video on here that genuinely makes me happy I learned something new. I was well aware of the batteries inside these packs, but never even thought to try to open one. I have the individual 18650 charger for my vaping batteries which indecently are the same cells just usually much higher drain. Anyways I have so many old packs that don’t charge well that I can now mess with and try to make good again! Thanks for the amazing info.
Please if you have a chance do some videos on building/repairing or improving EGO batteries for blowers trimmers and mowers if you could. Thanks again definitely earned a sub and a like!!
I tore apart a couple of DeWalt batteries and recovered LG he2 and Samsung 25r cells which are pretty good vaping batteries. Been using them over a year.
Great info just purchased new Dewalt batteries, so wish I seen this vid before throwing away old ones. Putting this in my save folder for reference
Very good video. I have been fixing the small tool batteries in my Ryobi One+ (18v) for years. Most of the time, I take out the batteries and bypass the BMS and charge/jump it with a good back. Then if it charged up, I put it on the charger and 90% of the time I am good to go. Very occasionally I find a bad cell and grab one out of my stash and I am good to go. Good advice and description on this video. All the best!
Good information 👍.
Ginger sure has good discipline, and she is so cute. Nice to see her paw has healed.
Thank you very much, good quality info and very thorough. I've had 2 part Blue Healers they are wiser than some humans I have come across.
Great way to save money and we all need that these days 👍 Stay cool 😎
Good Info, always like to know how to repair things. Even more true if it is a situation that you can't get "new". I've had 3 Milwauke M18 batteries that are about 15 years old. They still charge, and although not as good as they used to be, they do still last a good time in a drill, impact driver, sawsall, or flashlight. Now my M18 leaf blower, or other high amp tools, will run them down pretty quick. But they are so old they don't even specifiy the Amp Hour Rating 😁as that wasn't really a thing back then. They are just labeled as "HD", but guessing they are approx 4 ah. But I have a lot of new batteries too, but still use these old one's on a daily basis.
Lithium cells are quite impressive for there size, just look at modern jump start .
So much current , amazing.
Your dog is just loverly, she is so forgiving.
Yes, thanks
Unfortunately they still lack the power density of Gasoline....among other issues.
Battery technology is really holding back the capabilities of electric motors.
Wow thanks for sharing your ideas are on the money like the way ya showed us ya made it look easy without breaking the bank on tools ya got my vote signed up for more information 👍
Thx for a great video! Replaced cells this way myself on a Makita 18v pack.
Awesome video, I wish I knew this years ago. I’ve spent a small fortune buying battery.
Figures. Manufacturers want us to buy new but often isn't necessary. Great job showing us how to save money and be easy on the environment.
Subscribed for all the great practical info bro., all other videos were terrible but yours put it all together for me. Thanks and God bless!
Great begginer video. I'd also recommend lead solder. It melts at a lower temperature and makes it easier... also a spot welder for more advanced users. Cheers
Been looking for something like this. So many packs laying around. Heelers FTW!
man this is good. You gone start bein one a my favorite channels!
I like the setup of your shop. Makes a great background that any gesrhead would admire. Looks like a ideal spot to enjoy a cold beer and good friends. Excellent video dude.
Hey thanks
ive found you to be the most informative source when it comes to anything relating to cordless tools and batteries. not all li-ion batteries are created equal. some of the older hilti and dewalt use lithium iron batteries which have a lower voltage rating but higher recycle rate and cant be charged off li-ion chargers.
This was a thorough video. Fortunately, I have got rigid, and I do not have to worry about this.
Thanks brother that is definitely a need to know.
Good dog and good info also. We had a red heeler they are so good.
Great vid, I like the soldering tips I struggled with that!
When mine go bad I go to Harbor Freight buy 2 or 4 Bouer Batterys and I just swa the cells into my Dewalt Packs. I use to have a Video of it I should have kept it up but decided to take it down. Funny I have that exact same 18650 battery Charger too. I have done everything you do lol! Great Video!
Another great video thanks I always look forward to your content
That is one cool dog just like his master. I had a 2P5S weedeater that had 3 bad cells. Now it's a 5S with half the life. Surgery was a little more complicated but she's still going strong where my corded one can't.
Awesome.
Love guys like this, so informative and easily looked over. My black and decker battery no longer charges and flashes red. Crazy i get this link on you tube a day after ordering a new one -_-.
Got my subscription off this video. I have a dead Craftsman battery pack that I didn't want to spend $100 to replace. Definitely going to do this instead! Thank you!
You can get a decent spot welder for about 24$ that uses either a high drain 12v lipo or a high amp-hr 12v car battery for power. They are made with two red pcbs for the body and have 3 buttons with a small oled display.
Thanks for the video. I just jumpstarted a Dewalt 18V battery just like you described.
Another great video!! You covered all the important items!! You are always thorough! Thank You!!
Good video thanks ! 👍
Got some old ryobi,
and newer worx packs. I think I'll try this 😊
Awesome video, I'm about to replace all of my ridgid cells with the fancy Panasonic jobs...
Amazing dude! I enjoyed this video! Thanks🖖🏼 regards from Sweden
Thank you very much for you time teaching how to repair the batterys 👍🏼👍🏼🤝 03-27-2023 7:18pm. ⌚
Bought a 30v DC power supply and it has changed my battery world. I can use it to test batteries, charge batteries and run motors. Fixed my first 12v dewalt battery pack today for free (had a 1850 battery) and had my tool up and running in the same hour! Electric cars are coming we have to learn how to do this... :D
I agree with what you said about electric cars. Whether we like them or not..they are coming and we need to know how to repair them properly. EV batteries are more complicated of course, but most of the principles are the same. Which model of power supply did you choose?
Excellent knowledge as always Mo!
Thanks!
Much appreciated!
Thank you! I got a nice Craftsman full drill kit at auction dirt cheap and none of the 3 battery packs hold charge. I plan on using 1 of the 3 to revive the other 2. I knew if was possible from your other videos. This shows me exactly what I need to do. And what not to do. I’m working with my 8 month old boxer-pit mix to be as well trained as your dog. She might be too dumb or too smart to be trained. I’m betting too smart, but I will keep working on her.
As soon as you accept the fact that dogs are much smarter than people the training gets easier... Establish a bond and be consistent Exercise her to wear her out before training bribe her with tiny treats every time she does good and it will all fall into place//
If you want a well behaved dog you have to establish and maintain dominance.
I used to have a Belgian Malinois. One morning I was taking the kids to school and forgot to close the door. I returned home to a wide open front door and a content dog laying at the top of the stairs.
Focus on positive reinforcement.
If your battery packs are year 2019, they are probably defective. When Craftsman V20 first came out, the initial batch of batteries all had defective circuit boards inside that would drain and kill the battery cells.
Cycling the charger on and off repeatedly sometimes fixes blinking codes too. Plug into a power strip with a switch to make it easier since most chargers don't have on/off switches. I've done it before and have used the batteries for years afterwards.
Grant me the serenity to accept the things I cannot change; the courage to change the things I can - and the wisdom to know the difference.
@@notcharles ......... ok?
Notice it's usually the cell in the front of batt pack?everyone I ever opened it was usually the front cell bad. Possible that there is a engineering problem with the batt management system on the negative side or a missing diode for back emf
I have pulled apart a few of my bad battery packs, but have not gotten around to replacing the cells. The M12 is a bit tricky to pull apart. What I found worked well for getting the cells out of the tight battery pack is to put some hot melt glue on the end of the battery and attach some kind of puller. I use the pullers that are used in paintless dent repair.
What an awesome idea!
I have used the ryobi soldering iron to Fix Sterling Silver Jewelry was impressed most of the time you have to braze silver
Great demonstration.
Working over a silicon mat can help with solder spatter or battery fires. Someone mentioned a sand bucket, not bad but make sure you’ve got a pair of tongs.
One thing to consider is that most of the cells in these packs were manufactured in the same batch, put into the battery at the same time, and likely have similar wear characteristics as ever other battery in the pack. It's only a matter of time where you see multiple failures in the near future (YMWV). This is a common issue in server RAID arrays for the same reason...all the drives are usually installed from the same shipment and are subjected to a similar workload over the same period of time.
Replacing 1-2 cells may work, but if you could spare a few extra bucks, and you can get cells for a price that makes sense, just swap all the cells.
It is true for server hard drives, but they aren't the same as batteries. I have gotten plenty of batteries that have 1 or 2 bad cells and the rest of the cells have continued working just fine. and most of the time they go bad because people don't regularly charge old batteries, which I recommend very much. They tend to drain by themselves faster the older they are but not all of them from my experience.
But how does this detriment Trump Supporters ?
This myth is often used by the manufacturers of the packs to try and dissuade people from repairing them. A cell dying is a freak event. The chances of 2 in the same pack dying in close proximity to each other is miniscule.
What an interesting reference to server arrays. I've seen the very same thing happen with batches of drives in raid arrays.
That is false. Cells do not commonly fail early. Plus in the video he told people to use good cells from equally old packs because its cheap to do as people throw non-working packs away. So you kind of went out of your way to post this false information. A tesla has thousands of cells, replacing one is riskier due to that. These devices have 5 cells.
*Keep on Rockin Brother !*
Great idea about cardboard cell, with jumper cables.
Great presentation! First time I watched your channel. You may have broached using heat sinks in the past for drawing heat away from area using a small heat shrink clip when wanting to protect adjacent areas. This is what we needed to do in some soldering operations in aircraft avionics repair, the F-111 specifically, where we did a lot of circuit board small component replacement. Great pooch too…. Thanks
Why would you have to replace the boards?
Interesting stuff , keep it going I have battery failure so I’m soaking this up, just no solder kit, haven’t told the wife either😮😊
U da man with useful vids, thank you. For tacking the tin strips you can also use a 12v car battery with nails. I tape off the wired parts where I hold them or you could make resin molds and cure the wired nail in it. But as little temp into the battery as possible is the target when you do that, just like with soldering. B.t.w, I think your dog wants payback for this trick of yours 😁
It's nice to get something done so cheap but I've found taking the shell apart to be the biggest task with some of them. Perhaps you can give a tutorial on taking each brand apart.
Good video, very informative. Thank you
This is the best and most complete tutorial I have seen. Ryobi batteries seem to be really prone to killing one cell, I am going to pick up one of those Kobalt packs and I can probably repair all 20 of the Ryobi batteries that I have on the shelf.
After loving the lawn implements I bought a drill set and yup… the 18V batteries suck
Sacrifice one to harvest cells to repair the others.
It isn't just voltage that matters though, you need to match the capacity of the cells in the pack.
Some battery BMS circuits will error out if some of the cells are discharging too quickly compared to the others.
Thanks brah! Like your info and your delivery.
Thanks
You can still those security tips in the torx screws and use regular torx too. Food for thought
Glad to have bumped into you. What about using one of the small, rechargeable spot welders for strap attachment. Soldering the wire to battery connection mocks me.
Good stuff, Moe. Thanks for your expertise.
Hey Thanks.
Thanks AMIGO!
You touched on an important subject regarding only using high drain cells. The biggest way people screw up when replacing all cells in a battery pack is by using laptop cells. Laptop cells have high amp hour ratings, but can only handle a fraction of the instantaneous current that high drain cells provide. Laptop cells will perform poorly under heavy load and will have a short life span.
what is a "laptop" cell??
@@kenluther9948 cells that are found in laptop battery packs. Low draw devices.
I've actually restored bunch of makita 18v batteries with laptop cells. Just use low ohm cells, i've used
@@hannessaariste3906 your example is the exception to the rule, and as such the comment was essentially worthless. Use your brain first.
@@johnrhodes3350 Well, not a good idea for some 5s 5cell packs, but definitely works when there are multiple cells in parallel. Also note that some chinese makita copys have much worse cells. After all internal resistance is what causes the voltage drop and why cells get hot.
Very well explained and demonstrated. Many thaks for a good video. Cool dog too ☺
Great information if you have a solid electrical background like being an electrician
Mooore power! Argh, argh argh! 👍Thanks brother.
I have an older Makita right angle drill that I've been wanting to replace/repair the battery.. 9000 was the # iirc. Might look into this even though I've got a Milwaukee right angle now.
I guess most people would throw them away, thanks for showing how to replace them
Only common sense how to fix something if you know how you save 80 to 100 bucks but I guess people like spending money. If you got a junk pad put a battery in it you’re good to go.
Hey that's a Queensland heeler, cool dogs ....
Thank you for sharing
Excellent to the point video.
I learned to solder batteries years ago. On the older BMWS the keys battery wirelessly charges and is sealed into the key. They are expensive to replace and I learned to cut them in half and install a new battery and super glue it back together. Gotta scuff and use flux and high heat, sticks to batteries every time. I was watching to see if there’s any other methods. I have always used acid based flux for batteries. I always clean them when done.
awesome thank you for doing this
I take a fine point punch and knock the center piece out of the tamper proof torx screws. It doesn't take alot of force to get them to break off.
Great information!!
Good applable information
It funny to me. Everything is going to battery's, cars,lawnmower,etc. But we can't keep a flashlight from dying 😅
Thank you so much!! Great job. Hey what do you think about $60 spot weld?
You never want to replace a single cell unless you test the internal resistance and you pair it with cells of similar internal resistance. Otherwise you are setting yourself up for disaster. Also only solder the battery if you are completely confident in you’re skills. If you insist on doing this, buy a little spot welding machine… and please be sure to match internal resistance, because tools these days draw a lot of watts and you don’t want a thermal runaway situation on your hands.
Wow you really remind me of a guy called "Myself"! Only difference is you dont apparently dont have any 80V kobalt tools, I definitely still use them, in fact they are among my favorites for sure! They have replaced all things I used to hassle with gas over, better performance and always ready to go, even the chainsaw, and I literally got them "Dirt Cheap", only one out of the 9 I had to actually repair, and its been great ever since. But I understand your conclusion since there is allot of those batteries that arent old enough to be bad for parts on ebay ! All mine have been been trouble free though and I work them hard. Still when they have replacement boards for those I would probably try my hand at getting a couple more going!
Excellent video covering many adaptors and combinations, but I could not see one that would suit my requirements.
I am looking for an adaptor using Makita BL1850 or DM18M type battery to power older Dewalt tools that use the Dewalt 18v XRP batteries.
Even a combination of adaptors would suffice.
Thanks for reading.
Nice one ! 👍🏼
Nice job and thanks for the tip
No problem 👍
Awesome sir!
After watching the first 3/4 or so a couple times and finally getting to the part where you mentioned Makita I totally deflated all tumescence!
I have around a dozen makita i batteries which are still fully functional. However the oldest among them are approaching the age of where this video was making me feel that rush of blood and perhaps engorgement when we think of our tools.
The terrible news about Makita and the “BUYNEW BUY OFTEN BUY NOW! mantra of the shareholders really was a bummer.
The small saving grace was the availability of the new pcb briefly returned some of that oxygen rich blood offering a glimmer of hope 😂
Wow Man U must love your tools if u chub up thinking about them 😂
Good video! They're all the same because they're all manufactured in the same plant and then Ryobi or Milwaukee just put their plastic covers on them
Put a dog biscuit behind his collar😂. It took our dog a while to figure out how to get it out. She rolls on the floor until it breaks.
That's a fun idea!
Good repair
Great video again thanks for sharing 👍👍👍👍
Thanks again!
Another great video .
Excellent tutorial. Regarding soldering in general, a few things to ensure good joints and aide the process: 1 - make sure the soldering iron tip stays tinned or effective heat transfer will be nearly impossible. 2 - skip rosin core and go with solid solder wire and use Solderlene flux with alcohol wipe clean. Better for metal-metal soldering is solid solder and Stay-Clean acid flux followed by liberal baking soda/water flush after soldering. Use a small amount of flux and don't let it run everywhere.
This is much cheaper than spending $80 for a new battery pack. Must try on several packs that just will not change.
I figured if one cell went bad the rest were soon to fail. Ohh darn should-a replaced the bad cell. Your 18Volt tool will frequently work off your 12-14 volt car battery. You can use one of your bad battery packs and see which of the contacts power the tool and connect a 5 or more foot wire which should be heavy enough(low resistance enough) that there isn't much voltage drop in the wire and put battery clips or something on one end and the battery connector on the other. Then if you are back in the woods and you've ran down all your batteries and still have 5 bazillion screws to put in you can use your car battery.
This is awesome knowledge 😅😅😅😅😅
I would recommend the charger I got while doing racing drones. It is cheap and versatile Imax b6ac. Great info on your channel as always but the charger can help with many other scenarios.
I wish I saw your comment earlier. Bought the charger he's using but found out about the b6ac. It is alot more versatile and would've been great to use. From what can see the can charge a discharge whole battery packs as well as individual cells? All the listings adverise the pack charge/discharge function. But I don't see why it wouldn't work for individual cell charging like he is doing(@2:20) when set to the correct settings.
Nice , thanks for the information
Thanks, I'm glad you liked it.
