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 :)

Thanks for doing that for us....very informative !!

Very important and well done investigation. THANKS!

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.

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!

The hell did you do for it to short out like that lol

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!

Very interesting, thank you for sharing.

good job on demonstration the 18650s battery test,we are vapcell battery,mainly supply for vape devices and flashlight.etc,hope to check it out

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

Thank you for doing this so I don't have to alot to learn in this video. Keep up the good work

It realy helped me, because I was planning to do this experiment now a days. Now I can think next.

Interesting and informative, great video

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.

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.

Also, he heald the soldering iron on the battery for a long time, if you're doing it right, you should only spend 2-3 seconds on each side

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. 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.

what kind of soldering do you do at 500 degrees??? the melting your iron kind?

I always wanted to know what a rechargeable battery looks like from the inside. Very interesting!

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.

What was the song?!

I've already done this.. Sometimes it smell really itchy and bad

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.

Useful research results to share with the community.

I enjoy your vids!

You are right. We must to solder it with high temperature and to solder fast. Soldar rápido.

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.

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.

Can you tell me what intro song you used?

Buen video. amigo...no conocia el material que tienen las baterias....Saludos Humanidad :)

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.

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

What is the name of the music?

How much for Chapati

When battery leaks, it has liquid come out of the cell... i didnt see any liquid come out thou... strange.

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.

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

Intro music please

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

The lead acid would probably fry the lithium cells

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?

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.

6:30 starts cutting the battery. You're welcome.

Interesting .. thanks

I would not even do this at work! But for protection sand or growel is better, and a fire blanket and perhaps a LithEx or similar.

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

There is no need to hold the sodering gun on it like your doing looks like your trying to destroy the cell

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.

Not overly scientific, but interesting never-the-less.

the answer is no absolutely not, or certainly not without a controlled atmosphere, oxygen will oxidize the lithium on contact, leave it to the manufacturers, just buy a cell appropriate to your needs

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.

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.

You held that on there longer than any I ever soldered

Спасибо за ролик!

You used light solder. You should use 100+Watt solder, which will solder negative side for 1sec. Battery will not get hot!

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.

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.

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.

A hole in the cell means the chemistry in the shell is at risk of being contaminated by the moisture in the air and so could either just not charge any more or if it charges could smoke and get very hot.
