The point is to show damage (or not) by going to an extreme. Not going to see anything if you solder it "properly" and quickly. But we can get a sense of some damage that might be caused if we see an extreme case.
Great video, thank you. I agree on the higher powered soldering iron. I use a 100W iron (usually used for making leadlight windows) and resin core solder. Get in there quick and get out :)
Great video! I have been soldering 18650 cells for years and have had no issues. I always state to be very careful with the positive and make sure you don't add to much solder and let it run down and short out at the insulating seal at the case. You actually showed the worst case scenario when soldering, not a clean tip, not enough flux, not hot enough iron and held it extremy too long. I also cool mine down with a wet towel after soldering. I know at the end you mentioned some of that but wanted to share more of my experiences! Thanks again, I have been wanting to do a similar video for a while. I still might one day showing a really good soldering job versus bad and see if a noticable difference inside!
Two points. First, if you solder quickly, no damage will be done at all. And second, these batteries are extremely dangerous to tamper with. The last one I accidentally short circuited blew up with such force that there was absolutely nothing left but a shower a copper particles and a horrible smell in the air. I never did find the outer case or anode cap! Fortunately I threw it out the door the second it started to go into meltdown - ten seconds later there was a very loud bang. Had I have still been holding it, I guess at best I'd of had fingers missing!
Thanks mate, I have wondered about the spot vs solder argument. I have soldered with a really high powered soldering station for years, starting back in the NiCD days with no noticeable effect on battery life. I was just soldering a stack of LiOn batteries last week, and I can say without a doubt my negatives were soldered in about 2 seconds. I find that if you lightly file or sand the terminals before fluxing, the solder sticks a LOT faster.
LIthium is an alkali metal in the first column of the periodic table. You DO NOT want to put a disassembled battery in a humid environment and absolutely should not have a tub of water to quench the flames. Very interesting video, I hope you find the inspiration to continue uploading again.
@@snausagesmcgee3963 you are right however typical lithium cobalt oxides are weakly bonded to the cobalt and are prone to violent and spontaneous reduction reactions. Thank you for that information
Using the good solder iron station with the larger tip at the high temp can be done within few seconds. The result will be the same as the spot welder. A none skill solder can be degraded the battery when using the cheap solder iron. Thank for the video which showing the internal of the batteries.
Very interesting experience. I know that you kept the soldering iron too long on the battery but I think that was necessary for he purpose of this test.
dudes keeping the iron on the battery for so long, put a small amount of solder on the tip first so that heat transfers better. Though not saying that u should solder it by applying solder from the tip, thats incorrect.
I agree with most here, spot weld when you can, solder to tags when you cant, keep heat to the cell itself to the minimum esp the bottom. Good vid. Thanks
You're supposed to rough the surface with crocus cloth or sandpaper, clean it with isopropyl alcohol, and use a 30W minimum iron worth a properly tinned tip. It takes seconds.
@@NERDVilleUK His autopsy most probably come first .. Visual inspection from an unconfirmed baseline starting point is useless ..... and i could go on for all the other reasons NOT to do this... BE SAFE .
I find the best way to solder these cells is with an old fashioned soldering iron that is heated with a gas blow torch , the process of heating the cells negative end is much faster and takes only about 3 seconds. we have been making up battery packs for R/C cars and boats for years this way and we have never had any problems. the iron needs to be red hot and much larger in its contact area.
Thanks. That was, somewhat scientific ;) Good enough though to show that soldering quickly with a stronger iron is best. That mostly goes for all soldering to sensetive equipment though. Common sense really. But good to see the internal effects! Thank you.
I soldered a couple of cheap new batteries but they were under the power that I needed, since then they are unusable, when I try to charge them my charger won't recognize them anymore and won't record the charging time. On most 18650s the positive end of the battery is on a small bridge that is sitting on the actual battery end.
I cringed watching this these are little bombs that I am surprised that the bomb service has nit been called to ask since these are probably class c explosives
Not sure who out there thinks this a failure. but I say it is a resounding success! He is not trying to give a soldering class, he just wants to answer the question so many of you "arm chair scientists "raise about heat from soldering destroys these batteries. I agree that it may not be good for them, but a good hi amp soldering iron along with good soldering skills will result in very minimal effect on the life of the battery.
soldering them is really like the last resort if you don't have a holder... But knowing that it does almost nothing to solder them could prove useful thanx man :D
LMAO...#1 NEVER use "plumbers" flux on electrical components....use ONLY rosin flux designed for the task! #2 "high watt 30" lol, you don't have a clue what high watt is do you? 75 watt minimum! #3 You should never have to use "sandpaper" on batteries, or electrical components...
The iron shouldn't stay on the battery nearly that long. Even a 40-60 watt iron can melt the solder on contact. Maybe try a lead based solder with a lower melting point. The lead free stuff is like 60-80 degrees higher to melt. Even with a smaller tip like that it should have flowed at contact. And its dangerous to just leave the iron on the cell waiting for the solder
Try a bigger soldering iron with a bigger tip. It has a bigger store of heat, so will get that neg terminal up to melting temp quicker. Oops, you said that at the end! Fantastic videos, and nice to see kids getting a hands on education.
"Got a small pot of H2O,,,,just in case!" . ...Just in case what? Just in case Lithium decides it doesn't love water today? In Case you ever decide to try this with a real Lithium Battery, in other words a battery that actually has some Metal inside it A.K.A a non rechargable Lithium batter...Leave Water out of your emergency plans because Lithium Explodes when it is thrown into water
Start by using a proper soldering iron. Yours is maybe a 25W. You need at least a 50W with a bevel tip (K- type) to transfer muck more heat to the battery, in order for the tin to spread on the plate. Then, NEVER USE PASTE FLUX with any soldering iron.
His soldering gun doesn't get warm enough he's cooking the hell out of the cell ! With solder flux lead your better sanding slightly the shiny part before soldering !Adding flox with a co0ld iron doesn't help .!
Great video!!! I've read that using a freezing spray prior to soldering helps protect the internals. Do you or any of your readers have any experience with that?
Its a good idea but normally a higher power soldering iron will give almost touch solder performance and this should be sufficient to prevent the battery from getting any heat damage.
Won't the 'freezing' effect increase the total time of the soldering process?I mean to say, won't it take much more time for the soldering iron to heat up the surface?Thanks for your reply :P
Just had a thought, what about the cold soldering irons? Well I guess that maybe not so good cause you kinda arc the lil v of the tip in or on the joint...I think
Thanks for your professional sciene study to illustrate the advantage of spot welding. Would you mind doing another experiment to disassemble an old Lithium battery? If the result is similar to solder welding, it means charging and discharging operation will generate the heat to de-grade the electrodes. Spot welding is for mass production of battery pack. For DIY users, they need to take some potential risk or damage for their battery packs. However, how to control the potentials, avoid some critical mistakes & initiate some important criteria. You will do a great job to tell us how to manage to solder a healthy Lithium battery pack. I guess that would be your purpose to post the video. Thanks for your reading my long sentences. Kind regards Wei
Your not using the thermometer correctly. You should be around 6:1-12:1 ratio away from what your measuring the temp of.. so you should of been holding the temp gun anywhere from 6-12 times the size of the object your measuring that's why you has such a difference when you measured the negitive side.
This would be interesting to see repeated using 2 identical, brand new, unused cells. Would the results be the same, or different, given that the new cells would have no wear and tear on them. Just wondering.
what I can say, you need to learn how to solder, you cant just leave the soldering tip on the battery terminal for long time... you should be able to do it under 3 sec if you have scratched the surface of the battery terminal..
🤣😂 it was his first time soldering obviously lmao. I figured if someone were to make a video on this you would have the proper tip, you would have the tip tinned and you would actually know how to solder 🤦🤷 but who knows lol. What do I know, I'm not a UA-camr haha. Was fun to watch tho😎
Don't you remember your chemistry ? Lithium reacts exothermicaly with water so dropping a burning or near burning lithium battery into water is only going to make things worse ! You could try that as an experiment...
It’s about The metal get your vape related battery advice from Battery Mooch (youtube, Facebook, IG). This video popped up in my feed, but it's a terrible example of educating people how to handle cells like these. There's no such thing as recommended mAh. You probably want the most battery life out of your mod. However mAh and amp rating go hand in hand. Usually the higher the capacity (mAh), the lower the amp rating (power). So depending on the wattage you vape at, you use different batteries. Don't use low amp batteries with high power. In general though Sony VTC5A is the best allround 18650 battery for vaping, and has been for over a year. It's got a very nice capacity, it's a solid power performer and it is very accessible. Whatever you do, don't buy rewrapped batteries unless tested and recommended by Mooch and use his ratings table as your Bible.
sand will not do anything it will just cover it up. you can use water but it need to be dropped into the container and if you add salt it also helps stop the chemical reaction. P.s water will not stop it but control it
the last time i did the same to a coin battery it blew right infront of me, good thing i put on goggle. battery really do not like to sustain heat for too long, spot welding safest bet
Sir, Esp since you have kids around: research what happens with Lithium and water. You should NOT have ANY water anywhere close by... What you did was highly dangerous! With a tub of water there... Also your cutting of the Batteries likely caused more heat then the actual solder...
Idiot, learn the difference between "lithium metal" and lithium ion batteries! Sounds like YOU are the one who needs to do some research before you WOW us with your infinite wisdom!
How to make it a proveable results , when your soldering skills needs improvement . Soldering a 18650 should be least 3sec and also sand of the top layer to make sure it's works .
I would not use such gloves - fire-proof is sensible minimum, but I would rather go ahead with no gloves, as pieces of battery material may stick to glove and make matter worse Using water and even having water nearby is awfully stupid idea while handling lithium - go ahead with sand, but water will make it worse - instead of having furious fire in single place you would end up with multiple flames flying around - water does not extinguish lithium fire.
You have not proved anything here. if you are going to prove anything you need to do it to more batteries ideally new ones so you can rule out amy damege from its use over its life. if it was me id do a capacity test before and after. Yes obviously spot welding is the best way if you are rich enough to afford one. But we are not all rich and make do with what we have.
Hi! is it safe to connect (in parallel) lead acid 12v 9ah battery to a 2 4s2p configured lithium ion (18650) batteries on a motorcycle? and wont it damage my motorcycle?
It does not show absolutely anything. Completely inconclusive 1. You need to know how to solder. 2. You need to perform it on new batteries. 3. You neet to perform it multiple times. 4. Preferably use microscope even if unprofessionally 5. Draw conclusions.
Strange how I left a damage lipo pack...which I open from a plastic casing..I forgot about it...One of the cells was leaking... and I was going to save the other cell..to run a big arss strip of LED lights or whatever toys... I forgot about it and Left it out in the RAIN...Not s damn thing :-( I did have a lipo pack exploded while on the charger thou..lol The reason why you dont want to heat the living shiet out of the 18650 cell is becuase of the circut protecton..it'll heat up ..Gas will simply form under it pushing up on the diaphram..disconnecting the battery/circut. Ive pressed plenty of diaphram back down..those so call you THINK were dead cells...sometimes reads...4.1 V FFS Lap top P.C. Most of the dead.disconnected cell are at the Micro processor area. it gets hella HOT there...not from the battery .but from damn CPU. That's the pATTERN....I recycle 18650
And why the hell does your multimeter take so long to get accurate volt readings. Mine is instantaneous... Never seen a multimeter do that... Must be old or cheap...
Interesting, I heard that lithium ion batteries can catch on fire if exposed to air or moisture, WELL, I guess u exposed that noise. Great Video. Thanks William
What heat damage would happen if you cut two round pieces of nickel the size around the battery soldered a piece of wire to each one and used heat shrink to hold the round nickel pieces to the battery? The heat shrink shouldnt take near the heat to shrink tightly, right?
Don't keep the soldering iron on he battery, just quickly melt the wire on top of the battery terminal.
The point is to show damage (or not) by going to an extreme. Not going to see anything if you solder it "properly" and quickly. But we can get a sense of some damage that might be caused if we see an extreme case.

since you would not do that when actually soldering it that makes it invalid.
Interesting video on how NOT to solder a li-ion battery.

Thanks for doing that for us....very informative !!
The positive side has a circuit breaker built into the cap. It opened from the heat of the soldering iron. The cell was fine internally.
CID - Circuit Interrupt Device
i believe this is activated by internal pressure build up@@davidbolha
Not overly scientific, but interesting never-the-less.
soldering them is really like the last resort if you don't have a holder... But knowing that it does almost nothing to solder them could prove useful thanx man :D
I was worried about holding the iron on the battery for 2 sec´s , like I do soldering them. Seems like I´m good and continue soldering.
Trick to do it is, clean it well with sand paper, use a smear of plumbers running flux, solder hot and fast with a high watt 30 or better iron or gun.
LMAO...#1 NEVER use "plumbers" flux on electrical components....use ONLY rosin flux designed for the task! #2 "high watt 30" lol, you don't have a clue what high watt is do you? 75 watt minimum! #3 You should never have to use "sandpaper" on batteries, or electrical components...
There is no need to hold the sodering gun on it like your doing looks like your trying to destroy the cell
My thoughts, you've read.
The iron shouldn't stay on the battery nearly that long. Even a 40-60 watt iron can melt the solder on contact. Maybe try a lead based solder with a lower melting point. The lead free stuff is like 60-80 degrees higher to melt. Even with a smaller tip like that it should have flowed at contact. And its dangerous to just leave the iron on the cell waiting for the solder
Sand both ends of battery then a freckle of flux...and usually a higher wattage iron works best so iron to battery contact is at minimal.
Was anybody else just waiting for something to catch on fire?
I though it was going to blow up for leaving the iron on it for so long
I heard that lithium ion batteries can catch on fire if exposed to air or moisture hhmm.
MythBusters tested this out and yes, humidity, impact, and heat will make it catch fire violently
yes lol
the sound of your chewing gum is absolutely atrocious ...
sounds moist
One of big enemies for this kind of Battery's is over temping...shouldn't make them over temp...strictly cause of damage in life and charge cycling
I'm sure you've learned by now, you have to scuff the surfaces of the battery ends to remove the shiny coating so that the solder with stick to it.
No YOU DON'T!
lol
Very important and well done investigation. THANKS!
Rough up the surface with a file before doing anything...then add some non corrosive flux, and use a temp controlled station.
Correct. I takeoff a thin layer of the surface with a Dremel, then solder and flux flow the instant heat is applied
It realy helped me, because I was planning to do this experiment now a days. Now I can think next.
Try a bigger soldering iron with a bigger tip. It has a bigger store of heat, so will get that neg terminal up to melting temp quicker.
Oops, you said that at the end!
Fantastic videos, and nice to see kids getting a hands on education.
You should only need to hold the iron on for 3-4 seconds. If you have to do it longer get a 100-150 watt iron.

whos chewing gum i know i kept hearing someone smackin
capacity is depend on size of layer the bad one look have broken layer ..so give you same voltage but capacity less than 100 Mah
You used light solder. You should use 100+Watt solder, which will solder negative side for 1sec. Battery will not get hot!
you discharged them to 0v? that alone should kill them.
He killed them so they couldn't get angry and try to hurt him when he cut into them
Ok anti jai bukel naman
both of those layers are lithium ions on aluminium or copper or nickel - in fact it is one contiguous sheet
what kind of soldering do you do at 500 degrees??? the melting your iron kind?
What was the song?!
Take a wider solder bit (this is not a micro chip.)

Can you tell me what intro song you used?
I'd be more worried about cutting my finger off with that cutting tool! Use a vise?
your soldering iron dosnt get hot enough my friend
your soldering iron is not hot enough
You held that on there longer than any I ever soldered
A foot and 4 inchs? no way... considering the Go Pro is around 59mm in width I estimate it to be around half a meter 500mm.
the tile is 12"x12", so my guess would be about 18"-20" but he never shows both ends in one frame, so it could be longer.
use sand instead of water to contain a bursted cell
LMAO water and Lithium ,, OMG he must have no idea :p
sand will not do anything it will just cover it up. you can use water but it need to be dropped into the container and if you add salt it also helps stop the chemical reaction. P.s water will not stop it but control it

High protection, but you did it around kids?
I've already done this.. Sometimes it smell really itchy and bad
Lithium and waster? Not such a good idea. 18650s are lithium based battery’s
It show the difference of soldering. And. Not because you keep on the the + - for about 2m to prove. Your point
Useful research results to share with the community.

The lead acid would probably fry the lithium cells
It does not show absolutely anything. Completely inconclusive 1. You need to know how to solder. 2. You need to perform it on new batteries. 3. You neet to perform it multiple times. 4. Preferably use microscope even if unprofessionally 5. Draw conclusions.
Just so you know, put lithium in water and you'll get spontaneous combustion. Fortunately you didn't have to find that out first hand
Strange how I left a damage lipo pack...which I open from a plastic
casing..I forgot about it...One of the cells was leaking...
and I was going to save the other cell..to run a big arss strip
of LED lights or whatever toys...
I forgot about it and Left it out in the RAIN...Not s damn thing :-(
I did have a lipo pack exploded while on the charger thou..lol
The reason why you dont want to heat the living shiet out of the 18650 cell is becuase of the circut protecton..it'll heat up ..Gas will simply form under it
pushing up on the diaphram..disconnecting the battery/circut.
Ive pressed plenty of diaphram back down..those so call you THINK
were dead cells...sometimes reads...4.1 V FFS
Lap top P.C. Most of the dead.disconnected cell are at the Micro processor area.
it gets hella HOT there...not from the battery .but from damn CPU.
That's the pATTERN....I recycle 18650
And why the hell does your multimeter take so long to get accurate volt readings. Mine is instantaneous... Never seen a multimeter do that... Must be old or cheap...
Probably because he can't hold his damn hands steady.
Acute means very serious or bad. As in acute pneumonia.
No, in the case of acute pneumonia, the acute means that it's very short lived. ie: you die fast once you have it.
Interesting, I heard that lithium ion batteries can catch on fire if exposed to air or moisture, WELL, I guess u exposed that noise. Great Video. Thanks William
Some do based on the Chemistry. There are many types of Lithium batteries
Get a new solder gun,trust me when you get one you'll se the difference.Get one with at least 60 I'd say 80Watts best.
Lol i tought there is a bomb inside …why this piece of paper is so dangerous ?
What heat damage would happen if you cut two round pieces of nickel the size around the battery soldered a piece of wire to each one and used heat shrink to hold the round nickel pieces to the battery? The heat shrink shouldnt take near the heat to shrink tightly, right?
How much for Chapati
6:30 thank me later
I enjoy your vids!
