I have used compressed air to reset the CID, make a cone end that will fit the end of the battery and have an air fitting in it about 5+ PSI pressure on the end of the battery will pop the CID disk back in place without touching it or damaging it you can also build a pressure vessel out of pipe and caps and a air fitting for a compressor and charge it with about 5+ PSI
Thank you Ms. Anna, Yours is easily the most thorough video I have seen on the subject. You have permitted your viewers to make more informed choices before blindly jumping into a potentially dangerous fix.
Thankyou very much for that very detailed presentation. I never knew that there was a pin that could be reset. I will try this out, now at least my 18650s have a second chance for service. All thumbs up...thanks again.
Very good video. It kind of busting the myth. Also would like to recommend to use a rounded point to smoothen the CID and the important thing is avoid creases to restore the flexibility of the plate when it pops out again.
One of the best overall vids I’ve seen on the subject. And, as you note, cells fail...FOR A REASON...a reset as you do it will NOT impair the protection and maybe even increase it in the future. A great bonus...Thanks Anna!
I really appreciated your demonstration, complete, concise and clear, a million of thanks Ma'am. I'm looking forward for another videos, especially the lifepo4 battery how to revive it.
Just a few things: First off the diagram I drew to show the battery protection misses an insulator between the outer housing and all the CID layers. Then I tried to explain that if you use a screwdriver to reset the CID and you bent the weak spot around the CID central pin with a flat head screwdriver this may prevent it from working properly. Thought my explanation of that might be a bit hard to understand. Also don't use a multimeter probe as I did in the video to do a CID reset if you decide to. I was in the process of moving and had nothing better suited on hand. I think rounding the backside of a suitable sized drill bit might be the easiest option.
This is pitentially, the BEST and SAFEST explanation about 18650 CID reset. However, I've been thinking about another less intrusive system to reset the CID. Since the CID gets popped out by pressure, could you reset it by applying air pressure to the top part of the battery? 🤔🔋 This will surely avoid any damage by scirung, and bending or cutting apart any part if the positive terminal.
Great video. Good point about testing to see if the cell holds a charge for 48 hours. Can also measure the OD to see if the battery has swollen: if so, should discard it. And perhaps measure the temperature with an FLIR-type unit. You should see a moderate and most imporatant, a uniform temperature as it charges. That way you could monitor a few at the same time.
i have some questions: 1. once the CID pops because of temperature, do you think that hot air also builds inside the battery because sometimes you would hear a whooshing sound when you press the CID back into place. 2. since the CID may not pop again after it is put back into place, there would be no safety circuit breaker anymore when the temp. goes high, so the battery will end up exploding if it gets too hot, or will the CID pops again?
Hey thanks for your questions and sorry for the late response. The function of the CID relys on the relation between temperature and pressure inside the closed cell. Even good cells have a slightly higher inner pressure when in use, this is normal and the CID is designed to not trip. If the cell however goes into fault state the additional pressure build up is caused by the electrolyte that evaporises which then trips the CID. As I explained in the video the CID either trips and simply disconnects the Anode or opens up and vents the cell. The sound you descibed when reinstating the CID is caused when vented cells close back up this is normal and actually a good sign. Also doing a CID reset will not prevent the CID from tripping again. In contrary it is now much easier for the CID to be tripped as the metal either is weakened by the deformation or already was discconnected. The key is to get the CID pin back in place without deforming the disc it sits in. But even if you deform the disk it will not prevent the function, just delays it a bit (worst case).
first thought for me was cmon a 30min video but at the end it made good sense. the flush sidecutter is a must have. i cant get the continuity test you did to give me a true indication so a 5 min pre-charge with an old Nokia charger and if it goes +1,7v it goes in the litokala if nothing shows the method you showed is a good way to go if one is willing to take the risk. now i will go to work on the 126pcs i took from ebike batteryes and was to chaepscape to throw. Thanks
After doing the CID reset will the battery work in the same application that it used to before? or we have to use the battery in the lower current application?( BTW thanks for providing such useful videos, keep doing the great work)
have just recovered a fully charged 18650, that overcharged and im on my second one Thank you. its annoying that here in the uk they cost so much to replace yet good capacity 18650s in the US are as little as 3 dollars each.
When I revived some of the cells, I noticed that it shows two different voltages, I get 2.54V when the positive probe touches the top terminal but I get 3.90V when I put the positive probe under the vent cap. What could be the cause? Also when I try to run a capacity test of the revived cell using the Zb2l3 module, I get "error 3" msg displayed.

I recovered 3 batteries 18560 with 3 different methods all 0v one was by opening carefully all the battery removed the metal casing from the top side and cutting the lead and boom I read 2v I did a new casing with pla plastic redone the lead and charge finish the other battery was easier I just took a driver and started extending outwards with a screwdriver from the holes the positive has somehow it did the trick 😂 the third one had a sever nickel short so I had to remove the entire top again as I did for the first but I kept portions and the metal cap to reput it together. The one that looks bulky now is the one with the pla plastic head but all charge and work great.
Hey anna. Can you do it with the round part of a pin? It goes through the spaces. It has a roumd head. No need to open the positive cap.. Would it be safe?
There is a better way. Press the positive of a fully charge one with the positive of the faulty positive one, then use a cable to connect both the negative sides. I use my fingers to press the cable onto the negative sides without any issue. Wait for at least 30 seconds, the faulty one will reset and able to charge again.
This video shows a cid reset . You are talking about an overly discharged 18650 battery that cannot recharge after dropping below 2.9 volts . Cid is a gas pressure thermal breaker type circuit breaker system built into the top of an 18650 battery .
@@ngoandrew8This will seem sarcastic, but it's a serious question that I always wonder about. What is the thought process when someone who obviously has no knowledge of a subject, or wrong information, chime in with such confidence. Like "Here is a better way" when it's 100% not, and barely related besides also being about batteries.
what about sticking the cell in a pressure chamber... using compressed air to offset the internal pressure of the cell with an external pressure? Not sure how much pressure would be required but I would assume it would be the safest way to reset the CID without physically damaing the cell... of course too much pressure could do damage i would assume. What're your thoughts?
In theory a nice idea if the CID got tripped in a way that the cell is still closed and you simply have to bent it back. As you correctly stated too much pressure would be bad. The cell housing is relatively thick compared to the CID metal ring. However I don't know if it is that easy to bent metal back once it bent outwards. It makes kind of a bulge which also makes it more stable structurally. But I'm not an expert when it comes to using compressed air to bend metals.
Hi Anna, I didn't even know they had protection. Do all 18650's have this CID ? I know some have a voltage cutoff to stop any damage to the cell but most do not. If you look around EBAY they seem quite rare. I had a torch switch itself on and flatten a cell and my normal charger would not respond. I charged it at 4.2V and 100 mA for 10 minutes through a buck converter and then it charged OK in my normal charger. I think a hard plastic knitting needle might be good for the CID reset. I still don't like the idea on sitting on them in a ECO car. Your pretty good with nail varnish to.
Hi JP, not all 18650 cells do have a CID but the easiest type to identify is the one I showed in the video as there are vent holes on its positive. However there are cells that have a CID but no obvious vent hole. It is covered by a piece of paper like material and blows off as the CID gets triggered. Basically I would treat all cells that don't have obvious vent holes as unprotected. Well actually even if a cell has a CID it is still considered as being unprotected. Typically a protected cell is a cell connected to a BMS (Battery Management System). Sometimes even called a fully protected cell. Terminology varies between vendors and manufacturers. Some 18650 cells I saw being sold as unprotected or protected depending on the vendor even if it is the same cell. The CID is just the last resort. You always need a BMS to protect it from over current charging/ discharging, over voltage charging and under voltage discharging.
@@PhysicistAnna It's a pity that so many things like torches don't have any BMS. I had one from China turn itself on and completely flatten the battery. I revived the cell but it's lost quite a bit of it's capacity. Thanks for the help Anna.
Good explanation but the CID is a safety measure and its not been meant to be resetted! If you do so, you do it at your own risk (of course - like anything elso you do...). When the CID was triggered it means the cell was under very unhealthy conditions and built up very high pressure. I heard about around 100 - 150 psi - which is a lot inside such a cell. This means it was probably very hot - so that the electrolyte degraded and the cell got dangerous to use. In some circumstances it can be that the cell can be used again, but it will never be safe again!
From what I'm understanding, a battery with even a miniscule charge, does not have a tripped CID? A tripped CID has zero voltage? This is new territory for me.
The bottom line is: any reseting of the CID is a bypass of a safety device and has potential for catastrophic failure. 😢 Somewhere that choice sounds cheap and dangerous 😮.
Warning: The CID is build in for safety reasons. When you manipulate this Fuse, no insurance will pay any money when you burn your house with such a „repaired“ battery.
Really like your nail colour.

How as the BMS faulty? What did it do?
I have used compressed air to reset the CID, make a cone end that will fit the end of the battery and have an air fitting in it
about 5+ PSI pressure on the end of the battery will pop the CID disk back in place without touching it or damaging it
you can also build a pressure vessel out of pipe and caps and a air fitting for a compressor and charge it with about 5+ PSI
Picture please!
Was it fitted like a bullet and pressured in one end only or the whole battery?
