An Excellent and informative video , Steve .............. need more of these ! IOn and old pc , and using an AtoD converter , got some software , and showed battery voltage over time , with a resistive load ... not one cell , met the rated cell capacity ............. 9900 mA hrs , is just ridiculous !! well done .
That protection is there to prevent over-current and over-discharge. That cell probably doesn't have a high enough CDR for vaping. I did this assuming the batteries would be sufficient and the regulator on my mod exploded.
I didn't realize until it was 2 late I bought a bunch of 18650s and the positive side has a giant nub when compared to my ecig batteries. I truly thought I was getting a good deal and my guess is these are cheap because their uses are limited. I thought maybe I could easily remove that cap but I don't think I can so it means I have to sacrifice one to see if I can or maybe sand the nub back enough for it to fit.
Steve Brace lol I was just messing about. Thanks for the video...I already did this, I just wanted to see if I did it the correct way. I wouldn't recommend people do this on mechanical mods, though.
+sc0tte1 Mech mods should use high current cells designed for the purpose, but if you're using a mech mod then you're probably well versed in the matter.
Slightly altering this method can also be used to turn a protected cell into a solderable cell. There have been a few times when I've been able to avoid the high cost of overnight shipping (and make a quick repair) when I desperately needed a SOLDERABLE 18650 cell. On a protected cell, peel or snip off only enough of the interconnecting strap(s) to leave enough as a "stub" sufficient to solder to. Leave intact as many as possible of the original spot-welds. The more original welds the better. Soldering to the strip stub(s) instead of directly to any part of the cell... 1) MUCH easier to make a fast, much higher quality solder connection to the cell(s), 2) Helps considerably in preventing internal heat damage to the cell(s) while soldering. *WARNING: a solder connection performed by an inexperienced person **_may be INSUFFICIENT_** to handle the high currents found in some vaping equipment or other equipment. This could lead to catastrophic failure of a cell*
Are you aware of the interference buzz on this video? If you haven't already, make sure you have a loop in all your cables or some RF protection and that cables that cross, cross as perpendicular as possible to prevent cross-talk. ...etc, etc.
my LG protection button to top 18650 not charging no power from battery but i brought this battery just last month never fully use now out of order any tips how to fix my battery
Just realize that the 0v is there for a reason... the battery was put to sleep by the protection circuit... although they can be revived in several ways, the longer the battery stayed in the “0v” sleep state the more unstable it can become (and this instability does not make itself known immediately... it could have issues many charge cycles from now). There are some uses for revived batteries, but vaping is probably the WORST possible use of a revived battery. Battery instability/fire/venting mostly happens during discharge...yeah, that’s right...exactly when the vape is in your mouth... please do not use any revived batteries for that purpose... and always treat revived batteries as suspect.
I have to mod a fresh pair I ordered to fit in a regulated mod, I think its time I bust out the electric sticker label machine and ID the set, and label they are without circuit protect if I ever grab them as use for anything else and forget.
good video I thought the protector was on the positive end. I do know they can explode as fast as 5-10 seconds and the homemade unprotected batts won`t work in some devices because of the need for the typical protruding positive end. But thanks for the video.
So, basically, it is NOT an 18650, (even though it is sold as such), but an 18655, or how ever much longer it is than an 65mm. This is frustrating to the Nth degree, & I haven't even had to deal with the problem. What is it people don't understand about the importance of adhering to standards?
Some jerk who's been in the battery business for 20 years tried to tell me "no" 18650's come with internal protection. It was in a meeting with my president and it made look like a fool because I had told my boss that they are available like that. Thanks Steve I'm gonna prove them all wrong!
Hello, I soldered wires with tin, we poles from the 18650 battery. Now I intend to remove this solder. what precautions should i take? if this solder flows into the ends of the positive pole, even if it is a minimum. can cause a short circuit?
tks for the video, my battery is fairly new but it suddenly stopped working when I used it in parallel with a lousy one, and since then its never recovered its charge, I think I must have damaged the protection circuit and it refuses to charge or dischage since..all protective cells are situated at the negative?

I have 6 18650 cells which I took off from from a laptop battery that was loosing it's charge in just 15 to 30 minutes. I took off the cells from the casing they were dead I did CID and the voltage increased to 3.7 to 4.2 v in each cell . I used it for my rc plane when I gave full throttle the voltage of battery decreased from 11.7 to 4.5 volt and after sometime it again came to 11.1volt .whenever I give load on these batteries their voltage decrease and gradually increase when there is no load .Please help
Great info. Can you tell me if I can replace a 3.6 volt-1800ah rechargeable LED work lamp battery with a 3.7 volt-3000ah battery without harming the LED? The battery length is not critical. Thank you kindly.
Thank you. The answer to your question depends very much on the power supply to the LED. If it is regulated, then the LED will be fine, however if it is only current limited by a resistor, then that 0.1v increase will increase the LED current and therefore temperature thereby reducing the lifespan.
Hmmmm, 18650's are usually charged up to 4.2 volts then can be safely discharged to around 3 volts. If your LED light charger will only charge a battery up to 3.6, that won't be a problem at all; that's actually a good thing. The only problem would be that you could potentially drain the 18650 down past 3 volts, which could damage the 18650.
you shud do more videos! very well explained! u seem to be very knowledgeable person. i was searching for laptop battery repair by replacing 18650 cells....can u do a video on how to nicely teardown a laptop battery without damaging the plastic casing?
+Saeber Tooth Thanks! At the last count there were 20 videos in the Steve'll Fix It playlist... Subscribe for updates. As for replacing cells in laptop battery packs; this is very difficult without causing damage since they are usually glued. In order to open the case without damage you need to apply heat and if there's one thing Li-Ion cells dislike, apart from a short circuit, it's heat!
i dont remember but i think i have opened a litium ion cell in childhood..there were long metal strips folded..i think two of them..had a habbit of opening everything i can get my hands on. i dont properly remember if it was li ion battery or a capacitor.
The description you wrote is exactly just what happened to me. I bought 8 70mm protected 18650 batteries and none of them fit in my Aegis legend Vaping device. It cost me $40 to buy 2 single unprotected ones from a shop. The bloke told me to do exactly what you are doing here. Now I have 10 Batteries. Just wondering if you have had any dramas since filming this video? All the do-gooders in the comment section sound like they work for the 'protected' battery company!
I've had no problems. IMO protected cells are for numpties who know nothing about energy density and cell chemistry. Just leave the unprotected cells for the grown-ups :D
I'm pretty sure that protected circuit batteries were intended for use in mechanical mods exclusively, which a large majority accommodate for various size batteries; ie telescoping. The mod your using has protective circuitry built-in. WHY would you do this?
I stripped the positive end of an 1860 and used it, ban idea, you only learn from mistakes, I fried my mod and was lucky the battery did not explode. I thought I could get away with it and did for awhile but got careless and caused a short. I knew it was dangerous and found out it was.
A guy working at the vape store had 2 of these and they touched other the wrong way and it blew up. They blew a hole in the asphault....yes it's very dangerous.
Picked it up from the motor trade in the UK. I'd get asked to change the tree! I can't see anything wrong with doing this so long as it's done how you, and I did it shops should explain the difference in size as good batts are expensive and I had spent every penny on the equipment so the mother of invention...
This blue one is technically a battery (which is cell + protective circuits, enclosure and stuff), while the others are just bare cells. And saying "bare cells" may not be 100% correct, because many cells does have internal protection, usually PTC, sometimes fusible links, but these are regarded as part of cell. Anyway - Lets just hope that all people are aware of dangers of using lithium cells instead of batteries, especially not brand name ones, as those little things can cause serious damage when they decide to go off...
Steve Brace Depends on point of view. From physical point of view - yes, but for the purpose of safety evaluation cell is a component of a battery. This sometimes leads to situation where battery is just a single cell with added markings when a cell is safe enough to pass battery tests.
I’m a techie and all you had to do was modify the spring contact by cutting it shorter of the device by one revolution and you should be set. The battery is much safer with the protected circuit intact.
People need to know what they are doing before attempting this, cells USUALLY come protected for a reason, short an unprotected cell and they will thermally runaway, potentially catching fire. However, with that out of the way, if you are using the cells in a device that has it's own protection, using protected cells will lead to HORRIBLE performance, as you have 2 separate current regulations going on at once, leading to substantially worse performance than it should be delivering. It can also screw with cell balancing at lower than 3.7v, substantially chopping the top off your usable battery life. Although it isn't 'dangerous' to use protected cells in devices with their own protection, you still shouldn't do it, unless you don't care about your device performing sub-optimally. The only REAL use for these protected cells are in primitive electronics, like flashlights, which directly short the battery across a bulb, or in mechanical vaping devices which also work exactly like a flashlight, only shorting across a heating coil instead of a bulb. Vaping device with voltage regulation perform like absolute dog shit if the cells are protected, that is, if you can even get a protected cell to fit inside in the first place... They seem to intentionally make the clearance too tight to even get them to fit in the first place, most of the time. So yeah, your vaping device has intentionally made itself incompatible with protected cells, for your own good. Even if you could get the cell in there, it would perform horribly, as it is doing it's own regulation.
Exactly, protected cells arent meant to be used on protected devices. That is also why is fine to use those unprotected, or removing the protection, when you are using on something which alredy has protection, like those new cheap power bank circuits.
Hi Bill. I amd a Nigerian prince. I'll be happy to provide you with my home address but needing will I be your credit card and banking details before i can release the funds alonf with all comecatuion thankyou plese reply soon............. :)
Steve Brace Really?! OK, I'll have that sent to you first thing tommorrow morning. But then I need your address. Sorry for the wavy typing, I am still at hospital and can only type with my mouth.
This whole issue with protected non protected cells is just stupid the longest protected cell available should be the industry standard size for battery compartments and than shorter cells can be compensated for by using a longer more compressible spring to compensate for the slight length difference.
These batteries are something to watch out for, my reasons shall be listed with explanation The plastic wrapping should be in VERY good condition, because the wrap actually keeps the negative side sealed in Don't overcharge your battery, a day might be safe but it's not wise Watch out for REWRAPS these are junk batteries that look real, but aren't even close, buy from trusted sources PAIR YOUR BATTERIES make sure you pair, or marry your batteries (long explanation, check a 3 min vid or internet search on that and edjumicatiom (educate) yourself Never over do your batteries, mech mods (unregulated) aren't for people that can't guarantee safety, buy a regulated mod to be safer, battery explosions are mostly common through mech mods where the battery is abused or ohm's law is abused
Hi Steve, I hope you would be fine just one question asking for a long time with many people but no one give satisfactory reply. I hope you can come up to the best to solve my concern and share the info with others as well. My question: i have a laptop battery of 6 cells of 18650 series, can i increase my cells by soldering three or six cells more because of this reason to increase the backup time. I have no issue if cells are coming out of battery jacket, Can the 6 battery cells chip board found in the battery can control the 9 or more cells at the same time without infected to laptop. waiting for reply..... Qaisi Kulkar
I would not recommend this as the balanced charging circuit would not work effectively. As laptops are usually left to charge unsupervised this would pose an unacceptable risk.
In addition to what steve said, battery cells in series should definitely be impedance matched...which means you need to disconnect existing cells to check thier individual impedance (to match it)...same true for capacity.. both should be within 10% of existing batteries. Lookup “cell matching of lithium ion cells” for more info.
Hi Steve, I was wondering if you would know if the ones on the right in this picture are safe to use? i.imgur.com/moWJ3jC.jpg?1 One on the left is what I currently have, and nee to purchase an extra one. Do I have to like you did or not use it at all cuz of the mAh? thank you.
+Fahid K I have no idea m8 :) The only advice I can give is not to believe the capacity printed on cheap cells until you have tested them through a full charge/discharge cycle.
Every time someone tells me to not try something at home...I end up trying it. Except anything to deal with Li-ION batteries. Screw that. There’s nothing more unstable than Li-ION batteries. Ex president trump maybe, but that’s about it.
Not very easily or efficiently, no... You need to cap the voltage at 4.2v and limit the current to the maximum charge specified for the cell. A cheap, adjustable (I&V) switch-mode buck converter would work though.
Sir, Can is turn my ac android charger as a power bank by ading this battery ?? I mean getting rid of AC with a rechargable battery ?? Yeah, Power cells are available, but Is that possible ??
+Nasr Awan Yes it is possible. Two cells in series and a 5v regulator (plus a heatsink and two or three caps) would provide a steady 5v but it would be inefficient. A single cell and a boost converter would be more efficient, but more expensive and since you can buy single cell power banks for £1/$1 it really isn't cost effective, especially if you factor-in the charging circuitry.
+micheals1992 The risk with this type of cell is that there never much clearance between + and - whether the cell is protected or not. Remember that the entire can is -ve and the +ve terminal is, at best, 3mm away from the can.
The instantaneous current is colossal. When the cell heats up, the internal resistance increases, reducing the SC current. The danger is not from shock but from the heat and combustion of: 1. The material causing the SC, and 2. Combustion of the volatiles in the cell. Physics 101.
+Steve Brace The ones i purposely shorted in my living room took a short time before anything else but hissing happened. It would give you enough time to throw the cell away from you into something very flammable. But on average it just vented, very dissapointing. If you are using the explosive ones tell me where to buy them.
I've never had one explode or even ignite, but I have been careless with short circuits and lit up a pair of stainless steel tweezers causing an irritating little burn. Personally, I find venting far more irritating: th-cam.com/video/jzvyQS64lzE/w-d-xo.html
I do know that this video is old, but it was some principle stuff in it, so it gonna be useful for some more years, please can you put light on points below? Do batteries in laptop are protected or not? What is the benefit of removing the protection? What if I add a protected battery in unprotected battery series? Is the battery you got was a Accuplus? (I have same looking stuff) Can I add backup to my laptop by which way? Attached for your reference:- i.imgur.com/ObHA9yu.jpg Please guide me back. Regards, Hemant K
The cells in a removable laptop battery are not protected, but the pack is. The benefit of removing protection is restoring the length back to 65mm and FIRE! :)
haha I tot it was my wifi interfering with a joule thief running a cfl in the background causing it, at least I know it wasnt my side of the buzz problem
it's just that I've got some protected cells (they claim they're anyway) that don't seem to have a protection circuit on the negative. they wouldn't fit in my power bank but I used some pliers on the power bank to squash the positive tabs flat and I can now fit them in and my unprotected flat tops still make a good connection because of the springs :) The reason I was asking was that I always thought it would make more sense to put the protection circuit on top because there's already a negative terminal right next to it so it would remove the danger of running a positive strip all the way along the side of the negative casing (which could get damaged and short and there's no protection in between that kind of short circuit)
+micheals1992 You make some good points, but we're dealing with legacy c20th technology. If these cells were designed today, there would be no way any sane person would give these cells type approval IMO ! :)
it seems like a protected cell could have the potential to be more dangerous then an unprotected cell if it was damaged. but over/undercharge and short protection are good things to have if they're using them in consumer electronics and EVs. Do brand new protected cells still have their protection circuits on the bottom?
+micheals1992 The 18650 and derivatives were never designed for consumer use. They were for encapsulated modules (like laptop batteries) where external protection was expected of the manufacturer. The single cell protection was added in the 21st century as an attempt to make them usable for consumers, probably driven by the e-cig trade (may your deity bless them!) It most certainly does not make them safer in the event of mechanical damage!
On the other hand if you try nothing, you learn nothing, of course he's saying don't do this at home. But it's not that "dangerous" just pay attention to what you do! Like when you cross a busy street.
Just use the proper battery in your vape and use the protected type in another device, i.e., flashlight, that compensates for odd lengths with a spring. Banggood sold me some re-branded used laptop batteries, would not charge properly, got a refund after 15 hostile emails. I would like to find a charger that will tell me the ma-hr rate if anyone knows a valid source, even Chinese.
No, Peter, I was referring to Mark's comment. (I guess I shouldn't have said "reply".) And I was accounting for two-fingered typing, considering the content of what he said. ;)
Well... Yes. The audio was supposed to be good but as it turned out, it wasn't and I provided subtitles for the inaudible bits. I'll just take a look at your videos for an example of what I should be doing... Oh. Perhaps you should change your name to Dom Doos?
There is a safer way to dismantle the Protection circuit, Remove the plastic then Lick the terminals.. Lol If ones Eye balls still work then proceed with the video Haha. Btw Comments are legendary

Anyway - Lets just hope that all people are aware of dangers of using lithium cells instead of batteries, especially not brand name ones, as those little things can cause serious damage when they decide to go off...
+mibars A battery is a group of cells. External circuitry on a cell does not a battery make.
Steve Brace Depends on point of view. From physical point of view - yes, but for the purpose of safety evaluation cell is a component of a battery. This sometimes leads to situation where battery is just a single cell with added markings when a cell is safe enough to pass battery tests.
I’m a techie and all you had to do was modify the spring contact by cutting it shorter of the device by one revolution and you should be set. The battery is much safer with the protected circuit intact.
Should i open it on home or not,sir?
People need to know what they are doing before attempting this, cells USUALLY come protected for a reason, short an unprotected cell and they will thermally runaway, potentially catching fire.
However, with that out of the way, if you are using the cells in a device that has it's own protection, using protected cells will lead to HORRIBLE performance, as you have 2 separate current regulations going on at once, leading to substantially worse performance than it should be delivering. It can also screw with cell balancing at lower than 3.7v, substantially chopping the top off your usable battery life.
Although it isn't 'dangerous' to use protected cells in devices with their own protection, you still shouldn't do it, unless you don't care about your device performing sub-optimally. The only REAL use for these protected cells are in primitive electronics, like flashlights, which directly short the battery across a bulb, or in mechanical vaping devices which also work exactly like a flashlight, only shorting across a heating coil instead of a bulb. Vaping device with voltage regulation perform like absolute dog shit if the cells are protected, that is, if you can even get a protected cell to fit inside in the first place... They seem to intentionally make the clearance too tight to even get them to fit in the first place, most of the time.
So yeah, your vaping device has intentionally made itself incompatible with protected cells, for your own good. Even if you could get the cell in there, it would perform horribly, as it is doing it's own regulation.
Exactly, protected cells arent meant to be used on protected devices. That is also why is fine to use those unprotected, or removing the protection, when you are using on something which alredy has protection, like those new cheap power bank circuits.
I tried this while I was not at home and now I am injured.
What is your private home adress?
Hi Bill. I amd a Nigerian prince. I'll be happy to provide you with my home address but needing will I be your credit card and banking details before i can release the funds alonf with all comecatuion thankyou plese reply soon............. :)
Steve Brace
Really?! OK, I'll have that sent to you first thing tommorrow morning.
But then I need your address.
Sorry for the wavy typing, I am still at hospital and can only type with my mouth.
dont forgotten to include the PIN number ant the security code form the back of the carf... K Thx Bai :)
Steve Brace
OK. I'll advise that. To use the meantime efficiently, do you have a video showing the over/under voltage protection circuit in action?
It's funny you should ask that, because: No.
i want to do this but Im afraid now
This whole issue with protected non protected cells is just stupid the longest protected cell available should be the industry standard size for battery compartments and than shorter cells can be compensated for by using a longer more compressible spring to compensate for the slight length difference.
These batteries are something to watch out for, my reasons shall be listed with explanation
The plastic wrapping should be in VERY good condition, because the wrap actually keeps the negative side sealed in
Don't overcharge your battery, a day might be safe but it's not wise
Watch out for REWRAPS these are junk batteries that look real, but aren't even close, buy from trusted sources
PAIR YOUR BATTERIES make sure you pair, or marry your batteries (long explanation, check a 3 min vid or internet search on that and edjumicatiom (educate) yourself
Never over do your batteries, mech mods (unregulated) aren't for people that can't guarantee safety, buy a regulated mod to be safer, battery explosions are mostly common through mech mods where the battery is abused or ohm's law is abused
can i replace power bank battery for vape please replyy i really need to know ;(
can i do that with orbtronic battery ?? its with double protections??
+Mahdi Gouda I have no idea. I've never seen one.
Hi ,
what is the brand and name of your mod? it looks very compact and portable, thanks
+wayne murphy It was an old Innokin iTaste VTR.
Do we start working on the negative end?
+Walkertongdee Yes. The negative, the NEGATIVE end. I really should have made that clear in the video... The NEGATIVE end. Negative.
Got it not the negative end:)
+Walkertongdee This is rapidly becoming the tower guard sketch in The Holy Grail :)
Or the holy hand grenade of Antioch sketch,LOL
+Walkertongdee oh god I really have to watch that movie again! :D
what is the name of your multitool ....i want to buy it
Hi +Sanjay Kumar. It's a Gerber Suspension. I don't know the price since it was a gift.
isn't it true that most protected cell batteries are not designed High draw?
Pretty much, I think.
@@SteveBrace But you realize that a vape is a high draw device right? I mean, its a heater!
@@GearGuy Not at 12W: 12/3.6 = 3.3A
Hi Steve,
I hope you would be fine
just one question asking for a long time with many people but no one give satisfactory reply. I hope you can come up to the best to solve my concern and share the info with others as well.
My question: i have a laptop battery of 6 cells of 18650 series, can i increase my cells by soldering three or six cells more because of this reason to increase the backup time.
I have no issue if cells are coming out of battery jacket, Can the 6 battery cells chip board found in the battery can control the 9 or more cells at the same time without infected to laptop.
waiting for reply.....
Qaisi Kulkar
I would not recommend this as the balanced charging circuit would not work effectively. As laptops are usually left to charge unsupervised this would pose an unacceptable risk.
In addition to what steve said, battery cells in series should definitely be impedance matched...which means you need to disconnect existing cells to check thier individual impedance (to match it)...same true for capacity.. both should be within 10% of existing batteries. Lookup “cell matching of lithium ion cells” for more info.
Interesting bit of info there, cheers.
Hi Steve, I was wondering if you would know if the ones on the right in this picture are safe to use? i.imgur.com/moWJ3jC.jpg?1
One on the left is what I currently have, and nee to purchase an extra one. Do I have to like you did or not use it at all cuz of the mAh? thank you.
+Fahid K I have no idea m8 :) The only advice I can give is not to believe the capacity printed on cheap cells until you have tested them through a full charge/discharge cycle.
+Fahid K the highest capacity brand name cells are 3,400mah so it's almost definitely a fake rating.
Every time someone tells me to not try something at home...I end up trying it. Except anything to deal with Li-ION batteries. Screw that. There’s nothing more unstable than Li-ION batteries. Ex president trump maybe, but that’s about it.
Probably best not to watch my "Shaking Unbuffered Nitroglycerin" video then ;)
@@SteveBrace I think I have to subscribe to your channel and TRY ALL THE THINGS hahaha :-)
Sir, is it possible to change through 12 volt Changer.
Not very easily or efficiently, no... You need to cap the voltage at 4.2v and limit the current to the maximum charge specified for the cell. A cheap, adjustable (I&V) switch-mode buck converter would work though.
@@SteveBrace I'm thinking that someone who asks if you can charge an 18650 with 12V, will not be across implementing a switchmode buck regulator.
can i charge safely after doing this? ??
+Mahdi Gouda You must ensure that your charger has reverse polarity and overcharge protection.
Sir, Can is turn my ac android charger as a power bank by ading this battery ?? I mean getting rid of AC with a rechargable battery ??
Yeah, Power cells are available, but Is that possible ??
+Nasr Awan Yes it is possible. Two cells in series and a 5v regulator (plus a heatsink and two or three caps) would provide a steady 5v but it would be inefficient. A single cell and a boost converter would be more efficient, but more expensive and since you can buy single cell power banks for £1/$1 it really isn't cost effective, especially if you factor-in the charging circuitry.
+Nasr Awan No, you need a 12v wet cell. The kind you put in a car.
In entire video ,i like just one scene,the smoking one ! ! ! ! ! ! !
Is this safe if you want to vape ???
That's your judgement call... I accept the risk as I can rapidly mitigate catastrophic malfunction and I only vape at 25 watts with 2x18650s.
😅😅😅I will just get a new Sony VTC 6
@@zahedzafar46 I've recently changed to the JayBo Reuleaux RX2 with 2x21700, 4Ah cells (2x30A)... Great vape without cloudchasing at 24W.
Use a dark outline for the subtitles so that they are legible over a light background like your arm.
Thanks Juan... I'm still learning how to make these moving pictures :)
White people problems.
if you take the negative off first you wouldn't have to worry about shorting it too much once you get to the positive. isn't that right?
+micheals1992 The risk with this type of cell is that there never much clearance between + and - whether the cell is protected or not. Remember that the entire can is -ve and the +ve terminal is, at best, 3mm away from the can.

If you bypass the safety feature it will just blow up wen the pressure is to grate
you are an idiot
Thank you for the clear explanation!
audio quality would be better
Is that a wooden knife?? What do you call that tool??
+225rc It's a letter opener made from Damson wood. Anything sharp and non conductive will do.
seriously guys, he's not kidding. i did try this and mine started smoking.... don't try this at home
The trolls don't understand that several hundred amps can be a bit hurty... But that's just natural selection :)
+Steve Brace Where are you gonna get these several hundred amps? From your very special 18650?
The instantaneous current is colossal. When the cell heats up, the internal resistance increases, reducing the SC current. The danger is not from shock but from the heat and combustion of: 1. The material causing the SC, and 2. Combustion of the volatiles in the cell. Physics 101.
+Steve Brace The ones i purposely shorted in my living room took a short time before anything else but hissing happened. It would give you enough time to throw the cell away from you into something very flammable. But on average it just vented, very dissapointing. If you are using the explosive ones tell me where to buy them.
I've never had one explode or even ignite, but I have been careless with short circuits and lit up a pair of stainless steel tweezers causing an irritating little burn. Personally, I find venting far more irritating: th-cam.com/video/jzvyQS64lzE/w-d-xo.html
Nicely done! I like your video.
What's with the fuzzy humming sound coming from your video?? Are you bugging me ?
Nonononono... Yes. Sorry ;)
I do know that this video is old, but it was some principle stuff in it, so it gonna be useful for some more years, please can you put light on points below?
Do batteries in laptop are protected or not?
What is the benefit of removing the protection?
What if I add a protected battery in unprotected battery series?
Is the battery you got was a Accuplus? (I have same looking stuff)
Can I add backup to my laptop by which way? Attached for your reference:-

Please guide me back.

The cells in a removable laptop battery are not protected, but the pack is. The benefit of removing protection is restoring the length back to 65mm and FIRE! :)
1:52 check how u kick the knife. wtf is this
Clumsy :)
Thanks for the video and information.
+assemshawkat You're very welcome. Thanks for watching.
the protected is made for a flashlich
I got old watching this.
Oh dear... Let me just land my roflcopter...
You learn't something though !
And next we will make a baja salad with lemon chilli dressing and plenty of fire.😀
dont try this at home na i try it on the road
Thats no fun compared to RESETTING an 18650 after a short
Your mic buzzing like crazy is probably a grounding issue.
+killerbeenl More like a cheap FM radio mic too close to a CFT lighting rig and 11 computers! :)
That can be a issue ;)
haha I tot it was my wifi interfering with a joule thief running a cfl in the background causing it, at least I know it wasnt my side of the buzz problem
fidel catsro Good to hear from you comrade! How's Raúl coping with his new responsibilities?
do all protected cells have 2 layers of insulation?
+micheals1992 I would assume so since there has to be a high current conductor passing the entire length of the cell. There may be exceptions.
it's just that I've got some protected cells (they claim they're anyway) that don't seem to have a protection circuit on the negative. they wouldn't fit in my power bank but I used some pliers on the power bank to squash the positive tabs flat and I can now fit them in and my unprotected flat tops still make a good connection because of the springs :)
The reason I was asking was that I always thought it would make more sense to put the protection circuit on top because there's already a negative terminal right next to it so it would remove the danger of running a positive strip all the way along the side of the negative casing (which could get damaged and short and there's no protection in between that kind of short circuit)
+micheals1992 You make some good points, but we're dealing with legacy c20th technology. If these cells were designed today, there would be no way any sane person would give these cells type approval IMO ! :)
it seems like a protected cell could have the potential to be more dangerous then an unprotected cell if it was damaged. but over/undercharge and short protection are good things to have if they're using them in consumer electronics and EVs.
Do brand new protected cells still have their protection circuits on the bottom?
+micheals1992 The 18650 and derivatives were never designed for consumer use. They were for encapsulated modules (like laptop batteries) where external protection was expected of the manufacturer. The single cell protection was added in the 21st century as an attempt to make them usable for consumers, probably driven by the e-cig trade (may your deity bless them!) It most certainly does not make them safer in the event of mechanical damage!
My laptop went into sleep mode and so did i watching this video
Lol. That was no more dangerous than removing a 9V from a smoke detector.
On the other hand if you try nothing, you learn nothing, of course he's saying don't do this at home. But it's not that "dangerous" just pay attention to what you do! Like when you cross a busy street.
Just use the proper battery in your vape and use the protected type in another device, i.e., flashlight, that compensates for odd lengths with a spring. Banggood sold me some re-branded used laptop batteries, would not charge properly, got a refund after 15 hostile emails. I would like to find a charger that will tell me the ma-hr rate if anyone knows a valid source, even Chinese.
every cell don't have it
I thought that is a radio! Hahaha
Kinda does look a bit like a radio, yes. However radios do not, under normal operating conditions, release clouds of smoke/vapour.
Great i messed up and shorted it.
just don't buy protected batteries. ?.......
good video, thank you
nice sound mate
Oh yeah... I'm a professnional :)
