[@jimmycees4042]

Yep, i have to agree with you on this video. In the last couple of weeks I've been researching and studying these 18650 rechargable batteries. I've watched a lot of videos on how to recharge a dead/ no charge battery but none of them show a long term or long term useage or the problems that could arise. You video here is gold and solid advice to all. Why? Because as you said, these batteries lost their charge for a reason, plain and simple. You video here tops my charts and i think is the best advice to everyone. Thanks.

1:33 ... what do you do with the recycle bin cells? Goes to Regular trash or salvaging?

[@HBPowerwall]

Typically I give them away - they are useful to someone most times.

[@HDXFH]

Pop them on the welder

[@vincentrobinette1507]

This is an excellent video. Typically, they don't recommend attempting to charge ANY lithium ion cell that has fallen below an open terminal voltage of 2.3 volts. Any commercially available charger has a built in threshold voltage under which, for the sake of safety, will not attempt to charge. In use, they say to cut them off at 2.8 volts. my designs cut them off at 3.2 volts. You still get well over 90% of the battery capacity, with enough of a margin, that it can sit for a while. In a radio controlled model airplane, cutting the main propeller at 3.2, leaves enough in reserve for flight surfaces, for a controlled landing. I typically cut the charge at 4.16 volts, rather than the full 4.2 volts, just to improve the cycle life of the cells. you still get 85-92% of rated capacity. By limiting the charge/discharge voltages, batteries last much longer, and are more safe. As far as this experiment, my results were exactly the same as yours. If you pick up a cell that shows 2 volts or less, it's ready for the recycle bin. Voltage balancing during the absorption charge is a must! Any time multiple cells are in series, it's imperative to have voltage balancing to guarantee that no cell exceeds 4.2 volts while charging.

[@johncoops6897]

It's well proven that voltages even under 2.0V (and even down to 1.5V) are perfectly safe in MOST cases. However, the risk of the cell being inherently damaged is greater as the voltage is lower, but more importantly the amount of TIME that the voltage is low is even more important. In any case, if the (previously under-voltage) cell comes back up and holds a charge OK, then it's OK. If it won't charge or won't hold a charge, then it's fucked. The cells are either internally damaged and cannot hold charge, or not... if they won't hold charge then they cannot explode because they are dead and there is no energy inside them.

@@oneeyemonster3262 I don't believe there are any 30C constant discharge 18650's at all! Not in drill battery packs, or even on the market. About 10C CDR is the best you can hope for, like the 22a cdr on the Samsung 20R which is common in drill packs, (25R is more capacity but slightly less powerful C rate.) Even the newest power cells, Sony VTC5a or VTC6 3Ah are at the same C rate ratio, they'd need a chemistry change to radically change that. At the moment only Lipo cells will pull that kind of power or more, not 18650.

[@solarandgardeningstuffandd8168]

I recently found out you should not beep test across a battery as it can damage that part of the meter. That part is for Resistance only. when you go across a battery or cell you are allowing it to discharge through the meter.

[@HBPowerwall]

Really - cool didn't know that! another tick for the banggood multimeter, it survived Pete lol

[@solarandgardeningstuffandd8168]

I have also found when pressing it down you need to gently and on all sides (holes) Voltage should be above 1 2 or 3. I also look for corrosion or leakage. (ie colour) If I smell the fruity smell then i Know its not good. I'm sure you know Lithium and water don't mix. (salt water would be more conductive and would probably be worse then normal water. Perhaps do a test out in some open space somewhere to see the difference? Now that would be an interesting video. Keeping safe at all times though

[@solarandgardeningstuffandd8168]

I didn't know until Dad told me yesterday. He does more electronics than me and has done for years. 3D Printers and RC planes etc. as well as cars (normal ones) too

[@korishan]

I don't see how continuity testing a cell would damage a DMM. They are designed to test continuity on live circuits (mostly low voltage). If there's there a break in a part (showing no continuity), the power is flowing through the meter. There are plenty of resistors in there to keep the current down to a minimum. Maybe what your dad had heard before was that you don't test and "keep" the probes on the points for too long. Then yes, that could damage the unit as there is still current flowing through and could heat up and blow the resistors inside the unit. Testing is only needed to be done for a couple seconds, really.

[@korishan]

Regarding the risks of introducing a voltage through the multimeter leads: *Yes, there is a risk of certain parts being damaged, especially parts that can not tolerate the 1 to 9 volts that a multimeter might deliver across the probes in continuity mode. The above is especially true when the component (or other components on connected traces, which will also be affected) is not powered. Many parts can tolerate voltages when powered but not otherwise. *To minimize the voltage, an option is to use the multimeter in resistance mode, at the lowest resistance setting - The higher resistance scales work on higher probe voltage, going by a quick check on a couple of multimeters at my desk. *Note that basic multimeters often combine continuity and diode testing modes, so the voltage is at minimum sufficient to forward bias silicon diodes and perhaps LEDs. This means a voltage of 2 to 3 volts.

[@justpassingby037]

Hi! I got an enook 18650 battery that died after over charging it, anyway to fix it?

[@richardnanis]

Interesting experiment! I have done nearly everything with those harvested 18650 from old laptop batteries. I tried to bring them to explosion (in a save environment outside) just with overloading, short circuit etc. - ended up only heating the cell up to probably 100 deg. C before the CID popped. I never resetted the CID. When a 18650 is behaving like here, it is internally massiv short circuit and has quite high of an internal resistance (it wont take much amps when trying to charge) but it heats up due to internal resistance and short! Anyway i found several cells very close to 0.0 volts and succeeded in recovering them to a certain extent. They tend to heat up on first charge quite a bit, so they must be under permanant surveillance in a safe environment, but after that first procedure they seemed to take a charge after having cooled down again. On the second and third try they didnt get that hot any more and kept their voltage for several weeks! They are still bad cells but i found a few on them that seem to recover even more after sitting for a year with mediocre charge. One of them only drops its voltage maybe 50mV in a month - which is quite reasonable for a bad cell. A good cell keeps its charge for years tough and i have a few which only show a selfdischarge of 10mV a year! But anyway - some of them can be reactivated to a certain extent. But i wouldnt recommend to do so, as they can behave very unexpectedly and can be potentially very dangerous! Never use such cells in your torches or e-cigarretes!

[@guygordon2780]

That first charge where the cell got hot was your mistake. You have to bring them back above 3v by charging at ~10ma (1/100th C). Do NOT let them heat up. The deep discharge has severely depleted the anode of lithium atoms. Trickle charging gives the lithium time to work its way back into the anode (between the sheets of graphite). Fast charging forces the lithium in, generating heat and probably damaging the structure of the anode. How good the cell is after a CID reset depends on how much damage was done before it popped, and on what caused it to pop. But you certainly want to avoid adding to that damage.

[@mathijspiessens8318]

if the CID hasn't popped, but the voltage is just low (1.5V or so) is it acceptable to revive these with an appropriate charger?

[@obelixer9751]

2018 - 2020 :) Tried it on a dead 4 cell battery pack. (not used a lot and lay in the shed over a year sadly 0 volt.) Popped the CID back into place and they all measured 2.x volt. Charged them slowly with 200mA and raised the voltage to 4.2V. (inside lipo bag) They stayed cool to the touch and now they work like they are new again but like any other lipo li-ion they are monitored and replaced as soon as they do unexpected things. As far as I could find out the CID was invented after a bunch of 18650 burnt "down" a plane (while on the ground) so, safety is cool but it's not uncommon that batteries form a small amount of gas due to chemical processes, and yes! pretty fast if charged or depleted incorrectly. Anyone using LiPo's in RC knows this and these are even more dangerous than Li-ion.

[@Doviruses.existbaileyonodysee]

i tried to charge a pack of these that was in the tin shed for a few yrs. after some time i heard couple of pops hrs between each other (one was without Doubt from the batt. i heard the faintest hiss. so akng side a tine bucket and potting mix i broke and cleaned all the connections. but b4 dropping it off to the local recycling place would it be sensible to try to isolate the positive terminals with something like liquid nails? as some of the insulation is off as i kind of yanked it apart trying to feel for any hot or bulged ones.😑 appreciate ur time.

[@ricardokenji1]

Is there a way to identify if a cell has been reset? (Eg: buying cells online that are marked as “new”)

[@HBPowerwall]

you might be able to peak into the positive end of the cell & see if there is any marking on the diaphragm

[@tomamerman7699]

That cell has an internal short. You can tell because when you voltage test the voltage drops from the continuity of the tester. There are many reasons for cells to have a popped cid. If you reset and test voltage, if that voltage drops while checking it, it's trash. If the cell voltage is over 4.3v after resetting it's trash. I have thousands of cid popped cells. I may make a video since we have the capacity to reset and test thousands at a time. And get some real data analysis. That cell in this video was bad from the get go. First sign was voltage going from 0.20, 0.19, 0.18, etc. Just from checking voltage. All cells that do that get hot. 100% of the time.

[@HBPowerwall]

Yep never a good cell to start with and given all cells are the same and the bms didn't work I'd have to assume that bms failed causing the cells to fail. All guesswork of cause but I think if you had the chance it would be fantastic opportunity to educate and learn

[@tomamerman7699]

Yeah because I've messed around resetting cid's. 90% of them worked perfect with no heat and no internal resistance issues. But I never really went in depth on the numbers. And we don't sell reset cid cells. For an information video though I think I can help with doing the testing in bulk and seeing the characteristics across the board

[@HBPowerwall]

I think that would be a great thing for the community - I've tested only 15,000 ish cells and every one that was zero went straight to recycling with out a second thought. Its a positive thing having an open debate about the topic - I just got 500 more 6cell laptop batteries so if I come across any more I'll put them aside for a 100-200 cycle test in the opus at one amp.

peter, when the lifpo batteries are that far discharged, recommendations are to charge them up to the minimum really really slowly. i suppose the "slow chraging part" is for the reason they do not get hot and degrade even more.

They just aren't coming back as you can see from some shots the battery voltage drops as soon as it's removed from the charger. These cells are toast!

[@nayt33z]

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 damaging the cell... of course too much pressure could do damage i would assume. And if the internal cell is still faulty, I would assume it would create enough internal pressure to trip the cid again. What're your thoughts?

[@peterfaber9316]

I've tried this, but with a very low current and it's a waste of time. You can get the voltage up again, even to 3 volts, but it doesn't hold the voltage. The moment you stop charging the voltage starts dropping again. In some cells slower than in others, but you can't use them. There is some level of shortcut inside the cell. May not be a direct (meaning 0 ohm) shortcut, but there is a connection somewhere between the anode and cathode. (Lithium dendrites have grown causing a connection.) If it still has some resistance the rest of the cell can still charge, but it won't do you any good if it discharges right after you stopped charging. The heat is caused because most of the charging current is dissapated into heat in the dendrites. Just a waste of time trying this, but a great way to get experience and learn that dendrites are real and what they do. Still, it is possible to drain a cell to below 1 V without dendrites inside. And in those cases it's possible to revive a cell. A faulty bms can allow to discharge a battery too much. But in my experience when you are able to revive a cell like that, it's lost a huge part of it's capacity. So basically, not a usable cell anymore.

[@HBPowerwall]

Didn't even consider them dendrites! I think the larger issue is we are all recycling cells we don't know the history of there for you must assume the worst and if they are bad now they have a better chance of being worse quicker later.

[@dejayrezme8617]

Thanks I was wondering that. You'd basically use a current limited bench top power supply, right? I guess once a cell is damaged, the risk increases that an internal short causes a runaway reaction.

[@peterfaber9316]

Dejay Rezme That's the fancy way. If you don't have that equipment, you take a healthy cell, and put it in parallel, with some resistors between to limit the current. For example 3.5 V cell and a 0.5V cell. R = U / I = 3 / 0.01 = 300 Ohm. Or easier, use a potmeter that goes to 1 Kohm and put a 1 ohm resistor in series. The voltage over that 1 ohm resistor is the current that's passing through it. You can adjust it with the potmeter.

[@guygordon2780]

That's one failure mode. But don't assume all reset cells act the same way.

I have four 18650 batteries that have been sitting in my drawer for 3 or so years, they're reading 0v but DO have continuity. Not sure whether to recycle them or revive them

[@markusfalk9459]

Test em. Charge up to 3.7V with a 100mA per cell, then 500mA up to 4.2V. Do this under supervision and on a fireproof surface, like a stone/metal. Let them sit for a week, checking how much they drop in voltage per day. If they stay at or above 4.15V they are usable but the might only last a year/self discharging problem. If 4.2V after week, they could likely be used for a few years. Take care.

[@HBPowerwall]

Charge them at 0.0001 amps for a week or two see if they creep back up,

[@baogiangsongque5507]

if 18650 cells after full charged then mR=around 100. CID indicate that 18650 cells had misused or degraded. it can be used for some loader under 350ma like flashlight or led, ardruino etc...if you used these cells in parallel then it will parasites power from other cell, for long time dont used around couple months, all other cells will going die or degraded lifecycle. if you used these cell in serial installed then it will increase mR that reduced high C perform, then your circuit going bursted. there are 3 mains things that happen: bad cell or low cost design( some mfg make these cell with low C for safety and low cost). second one is overloader( like harvert in laptop cells: due to bad idea on ratio battery and wattage of laptop, gold ratio is 0.2 to 0.4C base on cell but on laptop that ratio is 3C to 4C, so lifecycle of laptop battery = 1/(4C:0.4C)x1000cycle=100cycle x 5 day average=1.5 years.) third one is bad design and understanding of perform. support that you can find any twos cell that fully charged with same exactly mR (internal resistor ) then you can buy mega lottery. the best for parallel battery is install a disconnect switch by a mosfet or physic button. then a small starter battery will turn on these mosfet to connect all parallel battery for loader. if for couple HOUR not used then it automatic switch off to disconnect and separated all cell in parallel; but hey i think mfg never support or want doing like that.

[@9001greg]

idk what kind of baby flashlight you use, but mine certainly can't use such a bad cell lol

[@vector3071]

..when you household fuse blown under some circumstances we say overload.- you are throwing away all whole hause or just switch on fuse?????

[@HBPowerwall]

your logic is terrible .. I hope you stay safe..

[@Paul7mac]

No no No never parallel a low battery and a full battery you are giving it massive current.

[@Eric_the_Hiking]

That's right, and this guy didn't seem to know the risk. I'm a bit surprised that there aren't many people telling him this.

thats how you give a boost to someone whos car battery is dead

[@HBPowerwall]

equal parts of both sides - many will try now, many will not..

[@lucianlucian1386]

I am no specialist in this but I think that under that cid protection must be a resistor like thing, just to limit a bit the current. It would be interresting to know if The maximum capacity of a cell îs 3000mA, the charging current should be 10% of te total capacity?

[@tomnewtnt5718]

what you need to press to repair the 18650 cell because the protection has tripped and the battery shows 0v and it is OK

[@HBPowerwall]

Ok, so entertain me HOW is it ok if the PROTECTION of the cell put in there by a smart guy making them has triggered.. Your comment is dangerous at best.

[@ericchang7706]

I'm confused. How do you measure continuity between battery terminals without having a high current run through your multimeter? I thought this was a no-no. Maybe I don't understand how a DMM measuring resistance/continuity.

[@HBPowerwall]

or maybe i'm doing it wrong?

[@gregpelfrey2577]

you are correct, you cant measure resistance with voltage in the circuit, the meter wont cause high current though because DVM`s have a very high input resistance (11 mega ohm) so as far as current it wouldnt draw any more than your fingers across it. older analog meters would be damaged doing this.So the biggest problem is the meter would give a crazy reading, if i remember correctly, at that voltage it would still show the "OL" he was seeing. there are ways to measure the batteries internal resistance by measuring voltage across a resistor that is placed across the battery, then calculating battery resistance using ohms law (resistance = voltage divided by current, the current is calculated by the voltage measured across the resistor) you can search "measuring internal battery resistance" and it will give you the formulas needed and the specific value of the size and value of resistor needed

[@hansdegroot652]

So the biggest danger of using suspicious 18650's is when using them in parralel you risc a big short right?

[@bradj.3832]

Where is the vid on testing that rebuilt/repaired ryobi cell? Very curious on the current draw

[@HBPowerwall]

I can't remember lol it's been TOOO long

Hi, question please : I have old batteries LGDAHB31865 (Vacuum Cleaner) do not hold the load well..can I replace them with NCR18650B Li-ion MH12210 --Charger :15V 2A AC/DC Adapter-- Thank you

[@HBPowerwall]

I can't be sure but you could check out the worlds largest cell data base - secondlifestorage.com/celldatabase.php

[@rahmanocawni5618]

That's really good news from you. This is really good news from you. But I choose a cell with a zero and I pricked it with a sewing needle I noticed strong gas that came out of the body of it and when I measure the voltage, it is OK 3.9. Please explain this phenomenon to me. The cell was at zero volts at the beginning

[@shmuelnaarai677]

Great stuff! I need some info if available. Why would a 18650 cell stop charging at 3.4v? Thanks.

[@HBPowerwall]

Faulty Charter? High internal resistance? Faulty Cell - isn't too many options. Is it a 3.7v nominal cell - does it have a different chemistry?

[@HBPowerwall]

See more info on the cell here - secondlifestorage.com/celldatabase.php

[@daand12]

Had the exact same on a LifePO4 18650. Had a internal short in it, and was leaking acid from the - side. Even putting it accros a 12v battery didn't really do anything. It just heated up and done nothing. Gave it the last push by putting it in a fire.

[@johncoops6897]

No... You didn't have the exact same because LiFePO4 batteries don't have the CID in them. Of course your cell was dead, you already said it was shorted out and leaking fluid (not acid). So being surprised that putting 12V on it didn't fix it make you as dumb as dog shit, right?

[@paulbriody638]

before I watched your video I watch the one where you reset it. then yours was the second video I have just watched on KZbin. on the first video I follow the instructions to reset the battery, I am so happy I came across your video and want to say thank you I have now put them batteries in the bin.

[@HBPowerwall]

Good man!

[@MustafaUsekes]

There are dozens of batteries waiting for sale in the background. Why did you choose the 0.15v battery? Wouldn't you get better results if you tried it with a battery that outputs above 2V?

[@HBPowerwall]

a 2v battery wouldn't have a busted cid

[@taxibob23]

where did you buy that usb charger ?

[@balloney2175]

What about the lithium mineral in it, can we recycle it?

[@mpitogo]

I had a Milwaukee Fuel 5.0A 18V pack go dead. Was fairly new, I found 8 of 10 popped. I think it was transient event. I sat dead for a long time until I discovered and tried the CID hack. All read 3.0 volts from just sitting idle for long, long time. I charged them and it was back to normal, no overheating other than small normal amount. The charger brought them back above 3.2v in under 5 minutes. My 1/2” impact drive must have heated them up too fast last time I used the pack. If it was dead, dead like well under 1v, yep probably good to give up on them and recycle.

[@chibuzo7746]

Anyone know how one can buy fairly used lithium batteries like the one you have ? I will like to build q power wall, but good used batteries are pretty scarce her e in nigeria

[@compubyte2010]

Okay, forgive my ignorance, ( or was it cuz you were just testing continuity?) but at 3:20 when you tested the batteries for continuity, I noticed, you were doing the Neg lead, on the positive term, and the positive lead on the Negative terminal? Or was I actually reading it wrong?

[@aleksandersats9577]

I've done a few CID resets and most of the time I get fine cells that are working normally but I keep them in a fireproof container in case something bad does happen as they are fully charged. I don't plan on using them though and I will probably recycle them

[@angelisone]

Do you have contact leads voltages on Ryobi P193 battery? 1. Has three leads on the towel (face on right side); Front contact is +, Back is - 2. One contact on Left Base 3. Two contacts on Right Base

[@JonathanVaucher]

Could it be that some CID pop because of hydrogen pressure buildup in the 1860 can ?

[@guygordon2780]

Actually, it's Oxygen. And yes, pressure is what pops the CID. The question is what caused the pressure? High heat alone could vaporize the electrolyte raising the pressure. Overcharging leads to chemical degradation of the cathode, which is made of a transition metal oxide (like Cobalt Oxide). This is where the Oxygen comes from, and the damage is permanent.

Question: i rebuild my outboard electric motor battery pack 8x8 cgr 15650 cg. The motor power consumption was up to 1000Wt. The motor was from 2012. the production cells held the full-throttle (1000Wt) ... up to several seconds but not 30 minutes like suppose to do. At low throttle (~100Watt) motor was working hours. i decided to rebuild the battery pack with new cells. The new cell works well. The question is about the old cells. After one month of the rebuild, i checked the voltage of old cells and it changed from 4.14V to 4.12V for all cells what is looks good. No? do you know why the old cells were not able to provide high Wattage? I have checked the charging/discharging of one cell with icharher 208b and it showed that the cell got discharged/charged in 10 minutes by current 0.5A. In range 3.3 - 4.1volts

[@scatter1390]

G'day mate, I have a 52v E-bike battery full of those cells that was near flat and needed a charge up. The problem is when l hooked it up to the charger, the charger light stayed green, which meant the battery wasn't accepting any charge at all. The battery got a little bit warm though and stayed warm for a few hours after. The battery is dead flat (none of the 4 power indicator lights working at all) and it supplied zero power to the 1500w bike wheel hub motor, BUT when hooked to the charger, the motor spun over just fine at full power and the indicator lights on the 52v battery showed full charge. (I had the back wheel off the ground and is spun over just fine). But as soon as l disconnected the charger, the whole thing dropped dead again, no power to the wheel hub at all and the 4 battery indicator lights went out. Can you help? Is the BMS burnt out? Any suggestions would be most appreciated. Thank you.

[@HBPowerwall]

Is it because the voltage was too low and the charger didn't activate?

[@GEORGE-jf2vz]

Did this with 20 from a ups and they work just fine. No overheating while charging. Hold charge well and discharge normally.

your video is not a stupid.This video present what can be after make dangerous methods. Before 3 mounts i make this,and battery explode and burn me hand and face very bad.For that reason i never make this again.. In day of the accident. i forgot to use safety goggles and hand protection.I make 1 mistake move and punch a how in the battery and battery immediately explode....Kids never tray this at home if you don't know what can be happened .Thank HBPowerwall for show what not to make to prevent burn skins or dead. Thank you man :)

[@gamtax]

Had two deeply discharged 18650. Both had around 0.5V after resetting the CID. Slow charge it for 3 hours then charge them normally. Et vóila, can use them normally but didn't measure the capacity yet. When they are deeply discharged, they are really suck at recharging themselves back and just being good hand warmer.

[@HBPowerwall]

Your approach is nothing less than dangerous .. :(

[@hulkgqnissanpatrol6121]

Old vacuum had a weird pack where 1 of the 6 cells was normal and the other 5 showing 0.2v, I did this and I felt something push down, I tested it and it was at 2.78v so I sis the rest and they strangely all come to between 2.76v and 2.80v. It's been 15mins and temp is showing ambient temp of 22c and charging at 0.4mha. 👍 I'll definitely keep the temperature cut-off set!
