0v 18650 - How the CID works

- čas přidán 25. 04. 2016
- Tearing into a bunch of 4 yr old Dell packs I kept running into packs that had one or even a few of these "0 volt - Open Circuit" cells inside. They would not accept a charge and read infinite resistance on the meter. Finding this odd I tore into a cell to find out what was happening and surprised myself running into a short circuit! In my research as to why that was happening I didn't come across any videos or easy to find ones, so here's my contribution.
If you've watched videos on people trying to vent 18650's or blow them up with high current overcharges this is the device that "spoils the fun" when things start heating up. First this disc pops, but with increased pressure buildup it splits and vents.
Be careful! Don't burn your house down trying to save a few bucks, you aren't going to find a really good cell that has been through this. In testing capacities after "resetting" a few cells they all appear to have lost 1/2 or more of their original capacity. - Věda a technologie
I heard a hiss come out of mine as I was doing this. It went 0 Volts to 2.32 Volts. Very interesting... To the charger I go with it now. Thank you for this informational video!
Love your simplicity and openness man.
Great find.
few of my 0v 18650 cells were already in the dustbin, moment I saw this video I pick them back up and they are now back to life! Big thanks!
It's really awesome video. This video is more sharp than any videos that is recovered from 0v to its original capacity.
Thanks a lot!!!
Such a rare moment of experience, when a youtuber is actually really useful and makes all the difference - thank you very much!
The most accurate and detailed video about reviving 18650 long sitting almost dead lipo battery...i've seen many videos abou it and tried the same technique but couldn't get to light up a single led bulb...my issue was i don't have a multimeter at hand and tested my 6 dead batteries on a led bulb and a couple of other small light sources, didn't work so i am about to thriw them away for shit, THEN came along this great explanatory tutorial that actually shows how they work inside the positive pole, and that is what i was looking for, seeng what's inside and the functionning of it so that i can figure out a smarter way to revive the battery...
Pheww, just getting pumped up now on how to properly get that bumped up cone to go down and hopefully reviving the cell battery...im about to try the led again right now and hopefully it will work out as intended... Thanks again
There is no proper way to reset it....the cell is junk. It popped for a reason. How did it work out for you?
Thank you for the knowledge, I knew there was a safety device but nothing more. I know Li batteries can be hazardous so I never explored them. I still will not reset the device, but I like having the knowledge of what likely happened if it tripped.
excelent video, I overcharged a pack with the wrong charger and started hearing popping , immediately the pack went to 0 volts, after disassembling each 18650 some had 0 volts , after using your technic they are back to around 4 volts , thanks again for a simple full of info video 👍
Excellent finding! Thanks for sharing! I know it's been almost 5 years :)
Interesting! I've been watching a few 18650 teardowns and I'm realizing that there's a lot more engineering in them than meets the eye.
You all probably dont care at all but does anybody know of a method to get back into an instagram account??
I was stupid lost my login password. I love any help you can give me!
@Devon Sam instablaster =)
@Ray Bronson i really appreciate your reply. I got to the site on google and I'm trying it out now.
Looks like it's gonna take a while so I will get back to you later with my results.
@Ray Bronson it worked and I actually got access to my account again. I'm so happy:D
Thank you so much you saved my ass!
@Devon Sam No problem :D
Best video iv watched for a while amazing find there I'm just repairing a work colleges drill battery and found half of them are 0v thanks for the info
It's a very useful video help to rescue 18650 battery which unable to charge! Thank you for sharing.
You sir are a hero! Lol. I was about to cut into my LG cell and decided to do a quick search. Glad you did this man! Thank you!
Great discovery i recovered a dead 18650 and its working now. Thanks and I appreciate your video
thank you it is good to know the basic of recovery .
thank you i just saved 2 vape batteries and am pissed i threw away like one hundred dollars of them in the past like 10 years. i clearly over charged them all back in my day. but this taught me alot anyway, thankyou brother.
AWESOM. I have also awake a lot of cell by applying this mathod. It is effective when the cell is completely showing 0 volt. Very good explained.
Interesting to see this feature on the 18650, thanks.
Thank you for illustration the whole idea.
I've been tweaking with my 0v 18650 2p pair from my laptop battery for 4 hours, I tried putting it on charge and everything, this was the problem, thank you, now I don't have to spend to get a new battery, I understand the risks involved in using such a battery but it is what it is
Yup, risking a fire and burning down your house is definitely worth saving a couple bucks.
OMG maaaan, thank you so much. Been busting my head for a week now to why few of them just died suddenly
thanks for the post. I've run across this many time and I have just sat them to the side. Now that I have a good idea what the problem is I can attempt to get them back in service. Here's a idea if pressure tripped the safe device, use pressure to reset it. I'm thinking about 1 to 3 psi should be enough.
Very useful tip and advice. thanks!
Thank you very much! Same problem, same cells. I will try for sure.
Great knowledge about current protection here.
Very revealing. Thank you for sharing!
Thx bro, u answered all my Q's. Ur mind works like mine, I just needed to understand was going on.
I was interested to know the reason behind. You have explained well. Thank you.
Finally a good explanation of this situation
finally someone explains this, thank you so much
OMG, this finding is awesome dude.
Really thanks.
I need to test the capacity of batteries just now revived :)
THANKS! Just messed around with a few bad ones I had, ended up popping the cell so cant use them but sure enough, it read 4v after it popped.
That was really helpful, thank you!
Warning!
That disk shows that the cell overheated and is no longer safe. The cell was either severely overloaded or had an internal problem causing it to build up gas pressure. No matter what caused the problem, the cell is dangerous and should be disposed of, and quickly.
You are literally playing with fire. The cell chemistry has been altered and the cell is no longer safe. There’s a reason for the protection circuit and the vent release and it’s not to remove them.
Tell that to the Chinese which do the same to sell you recycled batteries with new sleeves...
Unless you puncture the disc or solder it shut (which is a bad idea for many reasons, i have tried it and it doesn't work anyway as it damages the cell due to too much heat), it will pop again in an overpressure event.
People need to stop talking shit about resetting the safety because they know nothing about it If they do
😬 lol
You can reset this feature but it will probably do the same thing again in future.. this has something to do with the charging of the battery because modern laptops have strong transformators and the batteries are not happy to suck so much current.. one more parallel (3*bat in series) would do the trick.. most probably..
@@paveljelinek772 You can't "Reset" the battery chemistry, the disk shows the cell overheated and needs to be tossed. Trying to use a damaged cell isn't safe or too bright.
At the very least the cell capacity has been decreased and you have no clue how much current it'll take to charge and you'll likely initiate a thermal runaway and start a fire.
There's a reason a cell overheats. Once that happens you're literally playing with fire. I can explain it to you but I can't make you understand it.
Great info I have over 35 batteries with 0 volts, will check them before recycle them. Thanks.
Appreciate this, going to try 20 cells I overheated by over discharging today :)
Great find
Great informative video
Thanks for your efforts 🌹
That pressure buildup release sound was stunning.!! :)
Me. Sounds like snap of branch. Subtle
Warning: The Designer of this batteries have build in this fuse for security reasons. When you disable this fuse the battery will work, but no insurance will pay any dollar, when you burn your house with such a repaired battery.
Ok damn you don't have to curse him ok?
@@IsraelCountryCube Ok, everyone is free to burn down his house.
I highly doubt a fuckin insurance adjuster is gonna know the battery was tampered with. You're reaching bigtime
Interesting indeed. I disassembled a dead HP battery pack today at work, out of curiosity. It was farly new, and its counterparts from the same batch all had 95-100% of their capacity remaining. Turns out 5 of 6 cells popped their top. The computer in question just got a spare installed, and I hope the same fate does not befall that one.
The screwdriver trick worked on all cells, but it remains to be seen if they are useful for anything.
They are, until they eventually pop again.. it's just a protection feature, and laptops draw alot of current, they would need at least one more 12V parallel (3batteries in serial) or batteries able to withstand sucking so much current from them.. they exist but are more expensive..
@@paveljelinek772 I decided to discard them without using them. Having built several hundred cells worth of ebike packs, I've found that heaters and
Thanks for explaining this, I was going to do the same trying to figure out those same issue…thanks
This work for me.Thank you!
Thank you. It's true. I can recovery many of my 18650 battery. If I don't see this video I don't know what to do with it. (when I use screw driver press to the hole I hear the sound like air come out and then,when I check it the voltage was come back) I very happy.
exactly what i'm looking for.. thanks for the video
This is a great video!
thank you very much bro, great share!!!
Great video!!! Thank you so much, bro!!!)
I have a pile of those that I thought were just bad Thank you for the insight
Well they are so...
Great video mate great to know about this
Thank you very much friend for this really instructive video. It´s the best on this theme !!!
I used this procedure several times but I didn´t know how does it work. Because of that I damaged several cells by puting too much presure and not in the wright point. Thank you again !!!
God blesses you !!!
Thanks so much for this video!!
That's brilliant, you have saved people a lot of money even myself,it's funny how people are jumping on your band wagon and showing this over youtube, your the star here and brilliant, loved your video kind regards colin from croydon surrey England 👍 👏 👍 👍 ❤
Thank you. For the great video
Thanks for the video. Very useful information. @2:48 You reference papers you've seen about the CID, could you share which papers these are or where to find them? Thanks
On my protected 18650's that had "popped" the protection button, I hold the bad one to a good one positive to positive and connected the negatives with a small wire for 5 seconds to reset the protection and they usually always reset and start charging.
Thanks broo
hell yeah brother that worked like a charm 1k thanks!!!!
thats if the cell is dead without the button being popped and there is still a connection to the anode
You're awesome! I have an 18650 I left it in a vape mod for over 2 weeks and it was almost ready for a recharge when I left it. Just last night I tried recharging it and it was totally dead and would not recharge and showing no voltage reading on my DMM. After seeing you vid, I tried to stick something into the vents of the top cap but I could not find anything small enough that wasn't sharp like a needle. But tonight I found a little old flathead screwdriver and was able to fit in inside the vent holes and push down the popped-up diaphragm like you show in your vid. I was a little startled when it released the built-up pressure, but it was only a split second. The battery is now charging. My only fear is why it built up the pressure to begin with. I have left 18650 batteries in stuff for for extended periods of time before and this never happened. I'm almost afraid to use it. But I am so glad your method worked! BTW: Nice Harbor Freight DMM! LOL I have a few myself.
Nunya Biznis I had the exact same thing happen when I left two batteries in my Smok Alien mod. Unable to charge them again in the mod. And for some reason my coil totally burnt out. Are yours still going well??
Excellent. Thanks for sharing this info, amazing. Just saving them for things like making light decoration for Christmas with some standard LED's where you not gonna stress the battery and it just helps cut cost of your projects.
Thanks it worked with me, found it helpful.
I would recommend that if you intend to reset, and reuse these, you should at very least closely monitor their temperature during both the next subsequent recharging, and reuse.
You absolutely nailed that.
YOU SAVED MY LIFE
I LOVE YOU
I was charging 18650s with a phone charger and being careful and throwing away ones that behaved different. A guy kept borrowing my batteries and bringing back junk. I charged one about 5 minutes and it was already getting warm. Took it off the charger and set it aside. About 2 minutes later I heard a noise and the battery was shooting flame from the negative end. It was spinning and hovering like a firework. It was loud and grey dust went all over. My Chihuahua Yoda was trying to get out of the room. It seemed longer but it probably hovered spouting flame about 10 seconds. Never accept a battery from a tweaker
Thank you for explaining how that cap works. It was very useful for me.
wow ..this is a great discovery of the year
great explanation videos, thanks ...
Thanx,, this was great info...
good work
thank for showing me detail
Hi mate, I have started my own rebuild station in my older timer mental regime~. Many of my rebuilds are on Vanon 'Knock offs' of Makita 3.0 Ah / 4.0 Ah / 5.0Ah / 9.0 Ah and found the similar battery cell in each. The cells all weighed in at mass =
Thanks for the explanation/breakdown. Prolly save about a quarter of the cells ive been collecting. Of course the safety trolls are gna troll. People can make their own decision on whether this is safe for their application/battery. Its a "proceed with caution" thing IMO. Ive actually had a small, 250mah drone cell go critical on me from overcharging after gas buildup inside. It blew and burst into flames right behind me, luckily, so I had it smothered in seconds. Burned through just about everything it touched tho. Lot of damage for a tiny little battery. Keep an eye on them if yall try this, watch closely for continued gassing and/or heat runaway.
Your the man! Thanks for the info
This is freaking AWESOME!
I repair so many battery
Thank u
WOW, many many thanks it worked for my SAMSUNG battery...
Good find
Great video, thank you. Now i don't have to get curious and pop one open myself
This is a good reminder video I knew about this but somehow it got stuck behind my head and having so many cells I didn't bother to revive them like that but now I will
No no please don’t do this, I know it’s too late, but the CID disk popped for a good reason...
@@fbi-federalblyatofinvestig3853 I only use those cells for solar lights and stuff like that
Oh, alright thank goodness it’s outside of your house, I did this and with a 16340 cell and it exploded in my laser while charging, that went on my list of things to never do again.
Too bad you didn't make many other videos about 18650 cells, this video is great!
Solid info. thanks.
Well explained thank you sir now I can revive my lithium batteries fast and easy 😊
Thanks
it's realy work for me !!!!
(AWT 18650 40A 3000MAH)
very good video, thank you so much
usefull info thanks ! gratz from qc canada
that CID acting as a fuse to the battery means that not recommended to use anymore
If you can keep your local fire department in your house, feed them, give 'em sleeping bags, let them shower, borrow your deodorant, etc. this method is terrific. But...and you knew there was going to be a but...these 18650's are great because of the current they current they can hold, and if that current decides to short through the Lithium, your potentially in big trouble.
On January 7, 2013, a laptop Lithium battery overheated (in a crate of them) and started a fire in an empty Boeing 787 in Boston. It wasn't flying at the time. Popping the CID is now a standard find on almost all Lithium 18650's in large part because of that accident. They found a way to make them safe. Please, don't undo that safety mechanism. Unless you can fulfill the first sentence above.
Give a man a fish and feed him for a day. In this case, teach a man to fish, and he'll have a fish fry.
Moments ago, I seen a video where the guy inserted a syringe and it restored voltage. No comments were allowed and no voice to explain what's going on. So I thought it was just a hoax and unliked the video. Thank you for the explanation and for allowing comments and for the education.
Thank you! saved my cells
Two thumbs up! Thanks
I just did 2 battery after seeing this and worked great thanks so much
Helped a lot!!!!!!!!!!!!! Thanks :D
Thank you! Very helpfull. This makes sense. I was thinking it was weird having 6 cells in a 6 cell pack dead, but this explains
Me too. There was another CZcams video on the same thing but he didn't explain the theory behind it. I did not want to blindly go into something unknown. Now I know. Good job.
Thanks for sharing.
Amazing! Thank you!
Great job.
It helped !
Very cool!
Wooden toothpicks working pretty good too!
And no danger of shorting with negative pole 😅
The CID is popped for a reason, charging these batteries will eventually cause a fire. A short-circuited 18650 can heat up and ignite even when not connected to anything if you reset or remove the CID.
Great informative video mate, cheers.
As you mentioned, this may not be the smartest thing to do but do at you’re own risk... 👍
Just wondering if you have tried recharging these reset cells ?
I have seen a video recently where the cell didn’t charge during the attempt but rather just got very hot very quickly indicating that the CID had popped due to an internal fault within the cell rather than it happening not by the fault of the cell but as you suspected, a fault of the charging system maybe overcharging the poor cell causing it to pop.
Just interested !🤔
Thanks.
Well done 👍
Excellent.
That's right, it's called protection not to explode when it has more consumption than it supports
