"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.

Making use of the kzfaq.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

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

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

rolling off the surface you pull from with the pliers is a nice technique

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

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

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

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

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...

You are remonding me of all of the batteries i got lyin around! I gotta get on it. Nice project :)

I look forward to more Makita DeWalt Craftsman

brilliant tutorial very clear and thorough thank you

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

You are an excellent teacher. I love your videos!

Very informative!!! Thanks for posting.

Really enjoyed watching, thumbs up!

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

I've been saving battery packs for years and salvaged some of the cells but indend to do a binge salvage some day soon.

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

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.

Good work champ, clear concise and simple in demonstration. Good on yea sport👀🗣👍

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

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.

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!

Dude. Thank you. I am encouraged by this.

Very nice instruction, thanks. Love the magnet hack!

Thanks for the useful tips!

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.!

Good Video for all of us to learn! Thank You!

excellent video mate! very informative! thanks a lot!

Excellent tutorial. Many thanks.

You're great! Loved this video.

You’re the battery guru. Thanks

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

Thanks for a very informative video.

Great video, very informative!

Really helpful, thanks for sharing. Greetings from Southport UK.

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

Excellent video..! I learned a thing or two there, thanks a lot for sharing. :)

Thank you ever so kindly, enjoyed your video.

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.

Great advices. It's quite some value to reuse some of those.

Great Tips, Thanks for sharing

dam the ones I threw out over the years, no more, great vid.

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

Thank you for this great video.

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.

1st class video thanks for the upload

Yeah man, thanks for the knowledge! No more pay new Batteries 😁

thanks..great video in plain speak

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

Great projects, really enjoy your channel

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

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

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

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!

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.

Awesome video, thanks

I like this very indepth. Also I like the phrase Goldilock Zone

thanks for good education, i need to learn much more!

You are good man, thank you.

Good video man. Thank you.

Great tips buk lau!

Great save

Awesome video, very helpful! Thanks for sharing your knowledge.

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

thanks for making it easy

Great video! Great info!

very informative thank you

Looking forward to the up coming videos. Great job!

Creative video, thanks :)

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.

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!

Nice info thanks.

good job bro useful tip

Way to go - I have a Vax Blade to fix and this may help.

Nice video

Awesome video! Im subcribing !

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...👍🏽👍🏽👍🏽

What a great buy!!

Just excellent

love the video!

Thanks!

You're dam good

Love the videos mate, but your accent is even better mate! Legit, it’s awesome haha. No insults intended.

Interesting vid👍

You can use those short bits if you drill out the holes a bit bigger.

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.

I liked it your video

can i mix laptop bats.with power tool bats. or is there a problem with the different discharge rate ? thanks for the great videos.

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

Easy to understand...0.Thank you!!! Subbed Will check out all your vids.

The video was so good, I had to sign in to give it a 'thumbs up'! Thanks! #128

learned a lot thx

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👍👍👍

i like your video and your accent

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 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.

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.
