DIY: Salvage high discharge 18650 cells from Makita tool battery for free

[@phoenixstacia527]

"The most common reason is cancer...skin cancer..I'm just kidding." You're so funny n 😍. Love your accent. Simple, clear communication. Informative. Thank you.

[@Magisktification]

The fact that the batteries are labeled fukushima somewhat confirms its likely cancer 🤯

[@brandondeyoung2771]

Also...green..dead give-away they're radioactive.

[@geminaritz]

Making use of the kzbin.infoUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type

this is by far the most detailed and educative on reviving dead 18650 bli-on battery cell video ever..kudos bro..

[@adrockmstar3239]

Great video! I absolutely love the way you talk!! Makes me laugh! But not at you, it just makes me happy.

[@iancampbell582]

Thats a very unique accent you have.Sounds like a mixture of deep south and European. I am only guessing though as i am Irish. Great video and very easy to follow. Much appreciated.

[@vuaeco]

"European" because I watch too much British television! :D

[@Lorddarthvader1701]

Just watched about a dozen of your videos. New sub too. Man did I learn a lot with your videos, glad I ran upon them....Not throwing anymore packs away.....great information

[@johnroper-paris1369]

Just come across this video, needed to learn how to replace damaged cells,. Fantastic video, so much detail and I'm really grateful. Can't wait to see what else I can learn from your videos. Thank You,,,,

[@TxRiverElf]

You are an excellent teacher. I love your videos!

[@Gerrit-Max]

Now I know how to repair my own power tool batteries. Thanks for a great video.

[@johncoops6897]

No you don't. You still need to capacity test, match and spot weld them back together. Also, when a pair of cells drop to under voltage limit, the BMS will often lock the pack so it will never charge again even with new cells. There is a lot more to it than the very first steps shown in this video.

[@giveme5]

Wow, what An eye opener! Great job man. Thank you for sharing your knowledge with us. Much appreciated. All the best 🙌🏻

[@toyhawker]

18650 cells are actually named for their dimensions. 18 means 18mm diameter, 65 means 65 mm length, and 0 means cylinder configuration. Thus 18650.

[@jessegil5101]

Im learning so much with this video. Thank you.

[@SVSunnyJim]

Wow, really talanted teaching there. Very easy to understand and follow. Got myself a few spare batteries now!

[@MrJerryjam]

VIDEO IS REALLY GOOD. I like your voice and tone of teaching. I have repaired a few packs for my own tools and some for friends. I have a Worx 24v pack for a line trimmer I purchased new several years ago. I purchased two of the packs (best that Worx had at the time). My wife left one pack on the charger outside exposed to overspray during high winds and rain, The charger was plugged into power. I discovered the battery and charger while I was troubleshooting the loss of video that the camera normally covered in the area where my wife left the battery and charger. The power supply for the camera was disconnected from the ACvcc and the battery charger was connected in the place the camera power supply normally is connected. I did not even think about yelling because after all, she does do all the string trimming around the place. I simply put the battery and charger back in the charging room where she discovered that one of the batteries would not charge this spring. I took the dead battery pack apart expecting to see all kinds of damage. There is no weather or rain damage. All six of the NCR20700B cells look perfect. However the voltage on each one has 1.9vcc and that will drain down to almost zero in about thirty seconds. I have not broken open any spot welds yet. I plan to jumper a 4v DC power source to each cell for about a minute and then check for voltage and voltage drop. I have not worked with any NCR20700B cells prior to this time. I suspect that they have been totally discharged by the balancing circuit protection system. The 30A in-line fuse on the - side of the load is good. If the cells prove to be defective then I probably will not order new cells at $9.US because Worx sells their newer 24vcc pack for $80.00US with 3Yr warranty. I can buy complete NEW Worx 20Vcc trimmer with 2 x 20V battery packs with charger shipped for $100US. One last thing: I suspect the battery pack was made by the same Chinese plant that Dewalt uses for their packs. I wish you much success. jj

[@vuaeco]

Looks like the cells are just discharged. The water probably just caused some short circuit and drained the cells. Try the parallel charging method for each individual cell to see if they would increase the voltage. Once the voltage increase to about 3V per cell, they will take a charge.

[@garychandler4296]

I found him very easy to listen to myself, very good English, but straightforward style that covers everything, just a little bit of rambling. Giving back: when stripping batteries with the thick nickel strips, if one doesn't want to come off, I would take a grinder to it instead of risking making a hole. I've had nothing but headaches with those HF meters, so I broke down and bought me a good old school analog meter: best thing I could have done!

[@anthonykalerkaler3517]

I look forward to more Makita DeWalt Craftsman

[@chuckmaddison2924]

This is a brilliant idea.I have been using new Aldi power tool cells for an electric scooter and skateboard. I use 26 cells ,13 series 2 parallel.

[@ericloso4758]

Watching just to hear this guys accent it's great!!

[@LD-zd5fr]

EXCELLENT video and very clear, calm explanation. Great way to recycle cells for IOT remote sensors. Thanks a million!!!!!

[@au3770]

Im sure what your saying is worth paying attention to but I honestly watch your videos because your accent is so cool 🤣🤣🤣

[@liamstacey419]

best analysis of the system that I have seen. Thanks a million.

[@dBritBoer22269]

Thanks!

[@rickhutson4564]

A FYI. The cells in parallel are always going to be the same because a electrical connection is made between the two. There is no way to measure individual voltage when they are electrically connected by the metal strip.

[@jimcatx3090]

Rick Hutson ya he said that in the video

[@jo9732]

Please become an electronics teacher. You are doing be world a great service with your videos.

You’re the battery guru. Thanks

[@darkbyte2005]

Great video, I tried it with a dead 18650 and old rc lipo and the 18650 came into life and I was going get a new one... Don't need to now.... Thanks for the great tip...

[@88ElevenShop]

That's some great content and production value. That kit looks great.

Might be a good idea to cut the plexi with a fan on and an open window, or do it outside. I love resourceful people!

[@MaxHammer47]

Even tho you posted this video in 2017, this is one of the best informative, educational, and entertaining tutorial I have seen. Great work!!! Oh , and I have Family, and I worked in Louisiana . I am wondering if that would be a Cajun accent? I will subscribe now. Have a good day.

[@dimik3855]

I think this gentleman is Chinese, and he knows what he's talking about. At the beginning I too wondered what the hell his accent is. Maybe he lives in one of the southern states. lol

Very nice instruction, thanks. Love the magnet hack!

[@williamevans6554]

i work in a skip yard we get lots of these batterys that builders throw away because they wont charge ,i will stat to save them from now on thanks for the information.

[@h8GW]

It'd be nice if battery recycling laws were enforced, but at least we have you to save some of them from the landfill.

[@brandonreid2351]

Dude. Thank you. I am encouraged by this.

Great informative video, and I have to say your accent is amazing, I've never heard one like it.

[@bernarddavis1050]

Southern Vietnamese.

[@TheDIDSBIAK]

It does sounds pretty much Southern 🤗

[@mon0railbredpig]

The voltage reads zero because there is no connection with the electrode inside. The positive end of the cell has a diaphragm that pops up with internal gassing due to heating, charging, and natural aging. You can press the diaphragm back down with a needle and release the gas to make contact with the electrode again. Likely have more than 50% capacity left in the cells reading zero volts.

[@TheDIDSBIAK]

I enjoyed your video very much. Thanks for sharing 👍 this will safe us a lot of money 💰 😄

@@savneetsinghrairai6823 - So you still didn't pay attention to the video, huh? I will repeat.... the batteries shown in this video are NOT the same as the laptop cells that you are babbling about. The fact that you don't understand what I am trying to tell you is the reason that I am mentioning it.

[@johncoops6897]

@@savneetsinghrairai6823 - NO, they are NOT Ni-CD cells. They are special "high current" 18650 lithium cells. This size is the same as what's usually used in laptop packs, however the output power characteristics are quite different. Lower overall capacity, but MUCH more power (amps) !! You really should consider not adding comments to a KZbin video until after you have actually watched it LOL

[@makeyourownsawdust9225]

Excellent tutorial. Many thanks.

[@iancampbell582]

I just wanted to make sure you understand my comment about your accent was absolutely not to offend. I find your accent very interesting as i have never heard anything like it.

[@vuaeco]

I understand, Ian. You're absolutely right on my accent. I live in the U.S. but watch too much British television hence the accent. American TV sucks, that's why. :D

[@chandlerdavis952]

On those security screws you can also take small flat head screw drive like what you would use on eye glasses and twist it between that pin inside the hole and they pop right off the you can use a standard torn bit . And use electric your drill or driver to the remove them. It's a lot faster

[@johncoops6897]

In almost all cases that will snap your flat screwdriver off leaving a shard of metal in there that blocks even a Torx Security bit from fitting in there. You certainly can't do that with Makita packs, the pin is exceptionally strong and you cannot drill it out either. Just buy a set of the correct bits.

[@TorstenNestler_KOOK-DiDj]

Hello and Thank You for this touturial. the details help me ! is very god ;-)

Good video and explanation. Your voice is easy to listen to. Thanx Big Thumbs Up!!!!!!!! I love to learn and you gave me a great education. I'm surprised someone tossed lithium batteries in the trash. I take all mine to the local hazardous waste for free disposal. Dumas disposal poisons all of us.

[@daveed1797]

Microwaves have that security screw too. The first time i was presented a screw like that and i didn't have the tool for it. I used a punch balanced on the center pin and managed to break it and then i could use the regular torx to loosen the screw. very informative about the batteries. i knew there was a difference i just didn't know what that was. Thank you!

[@raminatorrammer]

Thank you for this great video.

[@garyrichards6041]

What do you do with the dead cells? The place I tried to take dead cells to would not take them because they were not in the case the batteries came in. I try to keep the cases to build new battery packs.

[@mikespark72]

excellent video mate! very informative! thanks a lot!

[@takew4694]

at 6:58, I think you have forgotten one thing, the bottom cell would have the same voltage as the top one becasue they are connected in parallel. There is no point in measuring the voltage.

[@mikeacevedo7335]

Nice work! What is your opinion on salvaging other parts of the battery pack?

[@generationalgamers8925]

i just grind a divot with a dremel rotary tool in a normal torx bit, or a flat head screw driver at the right size will work or use a flat head screw driver to break that little nipple off, ive had that work great one time they snapped off like they were very brittle and another time or 2 it just bent over so then i resorted to finding or grinding the right size flat head that can fit in, but now if i can't find a security bit i make one with the dremel

[@STePHeN320_12]

At 1:22 they appear to be maybe Samsung cells perhaps? On the left from the laptop? The cell on the right looks like a Sony vtc

[@bolerdweller]

I need to make a battery pack for my old paslode nailer. I don't want to order more nicd batteries and I've got a few bad makita batteries. Could I just take 2 cells, make a battery and use one of the bmi chips from the makita pack and charge those 2 cells on a makita charger?

[@mainman9061]

thanks for making it easy

[@kriscarnathan8438]

great video, thanks for explanation. So basically if I'd replace bed cells the battery could work again? maybe control circuit replacement in case that its like 10$ and should be fine right? battery is about 80$ and control circuit 10$ so worth to invest i guess.

[@estegueydijo....]

Just a tought, if you recollect about 4000 of these batteries could you make a tesla battery pack?

[@primatroep9174]

most 18650 batteries are protected. that protection part is visible by taking that (+)cap off. sometimes that part gets burned creating that smudge on the connector. def dead! the openings on the side are not ventilation holes for the battery but for the protection. great vid though

[@markansas1337]

Do you have any videos of salvaging the cells from the kobalt 24v packs? I have a few of those, but I'm worried about damaging the cells when I remove the nickel strips. Thanks!

Did you try charging the battery before you did the test of 3 V?

[@olivernice8291]

I feel quite nervous doing this. Think I bust a cell trying to remove the strip. Got sparks and smoke. If the cell breaks whilst removing the strip as yours did could it start a fire or explode?

When building an ebike battery pack can you use different discharge rates in parallel. Like a 10a discharge in parallel with a 15a discharge? As long as capacity and resistance is the same?
