DIY: Salvage high discharge 18650 cells from Makita tool battery for free
Вставка
- Опубліковано 6 лис 2017
- This is the entire salvaging process of a Makita power tool battery. These are high discharge 18650 cells and you can basically power anything with them. The sky is the limit. Actually the sky is not the limit as you can fly a drone with it, too! Here are some other videos where I used the batteries for:
1. Quadcopter: • Drone battery hack: Ca...
2. RC car: • RC car battery hack: l...
3. Plexiglass cutter: • DIY: Home made Cordles...
4. More to come...

"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.
The fact that the batteries are labeled fukushima somewhat confirms its likely cancer 🤯
Also...green..dead give-away they're radioactive.
Making use of the ua-cam.com/users/postUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 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

18650 cells are actually named for their dimensions. 18 means 18mm diameter, 65 means 65 mm length, and 0 means cylinder configuration. Thus 18650.
Wow, what An eye opener!
Great job man. Thank you for sharing your knowledge with us. Much appreciated. All the best 🙌🏻
best analysis of the system that I have seen. Thanks a million.
EXCELLENT video and very clear, calm explanation. Great way to recycle cells for IOT remote sensors. Thanks a million!!!!!
rolling off the surface you pull from with the pliers is a nice technique
this is by far the most detailed and educative on reviving dead 18650 bli-on battery cell video ever..kudos bro..
Wow, really talanted teaching there. Very easy to understand and follow. Got myself a few spare batteries now!
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...
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
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.
You are an excellent teacher. I love your videos!
brilliant tutorial very clear and thorough thank you
Very informative!!! Thanks for posting.
Great video! I absolutely love the way you talk!! Makes me laugh! But not at you, it just makes me happy.
Really enjoyed watching, thumbs up!
Good work champ, clear concise and simple in demonstration. Good on yea sport👀🗣👍
I look forward to more Makita DeWalt Craftsman
That's some great content and production value. That kit looks great.
You are remonding me of all of the batteries i got lyin around! I gotta get on it. Nice project :)
Dude. Thank you. I am encouraged by this.
Watching just to hear this guys accent it's great!!
You’re the battery guru. Thanks
Just got a batch of hilti power tool batteries.. Samsung R25 2500mah. My project is a 15ah 29.4v pack only bottom balancing without BMS but with low volt alarm and lowered charging 28.5'ish.. Like your videos.!
Very nice instruction, thanks. Love the magnet hack!
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!
You're great! Loved this video.
excellent video mate! very informative! thanks a lot!
Good Video for all of us to learn! Thank You!
Really helpful, thanks for sharing. Greetings from Southport UK.
I've been saving battery packs for years and salvaged some of the cells but indend to do a binge salvage some day soon.
Thanks for the useful tips!
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
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.
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!
Excellent video..! I learned a thing or two there, thanks a lot for sharing. :)
Thanks for a very informative video.
Thank you ever so kindly, enjoyed your video.
Great video, very informative!
Excellent tutorial. Many thanks.
1st class video thanks for the upload
Now I know how to repair my own power tool batteries.
Thanks for a great video.
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.
Thank you for this great video.
Great Tips, Thanks for sharing
Looking forward to the up coming videos. Great job!
Yeah man, thanks for the knowledge! No more pay new Batteries 😁
thanks for good education, i need to learn much more!
Now, I'm not saying the video is not useful but you should learn battery safety from someone else, not that guy
I like this very indepth. Also I like the phrase Goldilock Zone
Wonderful, concise, clear video packed with tips. Earned a sub, and a like. Will have a new thing to look for at flea markets. Bravo
Im sure what your saying is worth paying attention to but I honestly watch your videos because your accent is so cool 🤣🤣🤣
Great save
Great advices. It's quite some value to reuse some of those.
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!
Great informative video, and I have to say your accent is amazing, I've never heard one like it.
Southern Vietnamese.
It does sounds pretty much Southern 🤗
Hello and Thank You for this touturial. the details help me ! is very god ;-)
Awesome video, very helpful! Thanks for sharing your knowledge.
Great projects, really enjoy your channel
I enjoyed your video very much. Thanks for sharing 👍 this will safe us a lot of money 💰 😄
Awesome video, thanks
thanks..great video in plain speak
Good video man. Thank you.
Great video! Great info!
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.
It'd be nice if battery recycling laws were enforced, but at least we have you to save some of them from the landfill.
dam the ones I threw out over the years, no more, great vid.
Right!
I was going to throw out makita battery but now i will try and revive it
Excellent video Sir. I found it very informative, entertaining and well produced. Let me say, without the intent of disrespect, I found it quite unique and honestly very entertaining. It sounds kind of like a cross between Asian American and a hint of cajun. It cracked me up a few times.
Anyway, nicely done! I have subscribed and look forward to your next video. Peace!
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.
"European" because I watch too much British television! :D
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.
Rick Hutson ya he said that in the video
thanks for making it easy
very informative thank you
Great tips buk lau!
Please become an electronics teacher. You are doing be world a great service with your videos.
Creative video, thanks :)
You are good man, thank you.
good job bro useful tip
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.
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
love the video!
Looks like makita use Sony Vtc . Not sure if they are vtc4, vtc5 or vtc6 . Good batteries for vaping .
You can use those short bits if you drill out the holes a bit bigger.
Nice info thanks.
Great job thanks.
You're dam good
Way to go - I have a Vax Blade to fix and this may help.
can i mix laptop bats.with power tool bats. or is there a problem with the different discharge rate ? thanks for the great videos.
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.
What a great buy!!
Love the videos mate, but your accent is even better mate! Legit, it’s awesome haha. No insults intended.
Thanks mate!
What accent?
Nice video
I am using these batteries from my childhood ..I remember batteries from handycam s....check ampage in laptop used batteries pack out of 6 may be 4 or five are good ...the good ones are very durable n hold big charge...👍🏽👍🏽👍🏽
You idiot - the laptop cells are not "high amperage", which is what THIS video is about. Pay more attention next time.
John Coops I think u r certified from dumassemberg university. ......go learn physics and then argue on amps....idiot
@@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 ok I got you these are not laptop battery cell ..they are Ni -cd cells and not are li -ion ..I took apart Sony viao laptop battery some two years ago cell were same green heat shirnked..well I didn't see full vedio you are right yeh ni-cd is compair nothing against li ion cells...yeh I was mistaken thanks for telling😊👍🏽👍🏽
@@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 UA-cam video until after you have actually watched it LOL
Just excellent
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.
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
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.
Your videos are amazing and you explain in so much detail and you are amazing guy. I going to fix my battery 52v 23ah for my scooter it meant to be hitting 58.8v but only hitting 57.9/58.0 so going to try you video to revive them. What's a very cheap DIY spot welder can I get? I have watch so many videos of your and don't see if you made one thanks bro👍👍👍
learned a lot thx
I got 4 dead miketa bats. Wonder how well they would work in my RC car lipo's are a pain constantly getting hot swelling going bad.
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?
Awesome video! Im subcribing !
Enjoying your content! Just started harvesting cells myself and have ambitious plans haha. I'm finding quite a lot of 0v cells in my laptop batteries (HP with LG cells) but I think the CID has popped - which makes me think that these cells are prone to failing??) Anyway, most have been between 1v to 2.5v but take a charge, will be tested them in intervals to determine if they discharge quickly... Keep making these videos!! I'll be searching if you have any DIY powerwall videos :)
I liked it your video
Thanks!
Nice work! What is your opinion on salvaging other parts of the battery pack?
Interesting vid👍
