- In this video I'll show you how to get free lithium ion 18650 cells from old and dead laptop batteries. I'm ripping a part only dead or no more usable laptop batteries. Lots of them are a bust, but some of them still had good cells inside.

TIPS : If you're planning to reuse it as a power tool battery and you don't have a spot welder, just leave the old nickel strip on the battery so you can solder it correctly and securely.
i've got 1000's this way :)
+HBPowerwall I'm folowing your power wall project. Epic amount of cells!
+Well Done Tips more on the way :)
Where do you get them for free?!?
combination of luck and hard work.
+HBPowerwall that's how, you were asked where though.
Good video for starters. The only warning I'd throw in is to limit your discharge rate to .4A to .5A max. Anything higher and you are shortening the lifespan of the battery. Yes, the discharge goes slower but you will have batteries that last longer.
When you get into measuring the capacity of thousands of batteries you will want an Opus BT-C3100 v2.2. This device looks like a standard four battery charger but it will allow you to measure the capacity of four batteries at once. I own five. The fastest way is to have another four battery charger on either end of the process; one to charge them to capacity, the C-3100 to measure capacity and a third to charge them after the capacity test. This lets me test about 100 18650 batteries per day.
I use the large capacity batteries in my E-bike. The smaller ones I use in cell phone chargers. I get the empty boxes from China for about $2.00 and simply add the batteries. I also use the lower capacity batteries in LED flashlights that take 18650s. Both the cellphone chargers and flashlights are used as promotional items for my wife's business. But using them for these purposes lets me write off my project on my taxes.
Hope this helps.

So you are part of that shady business of selling upcycled 18650 powerbanks...
test the voltage before you spend all the time making them look nice by tearing off metal lol
good point. that did seem tedious.
You can revive dead 18650s by wiring it in parallel with a good 18650
@@justinfoster6135 really? has that worked for you?
@@peksn yes, wiring a good li-ion cell with a bad one FOR 30 SECONDS will revive it there's just no guarantee that it will be fully recharged to its capacity but you should get 4.2 volts after charging it
Dead 18650 batteries seem kinda useless to me...
For the most part an useful 'Tip', but from time-mark 1:30->2:30sec this Tip is an excellent demo' of what NOT to do!
FYI - All these type of multi cell 'packs' are Arc or 'spot-welded' together (don't ask how!) because the metal terminals & cell-to-next-cell links are Nickel coated, so cannot be ('tinned') soldered together [YES, Nickel is 'magnetic', but cannot BE magnetised i.e. made into permanent magnets - weird I know]. Ripping them apart as shown will damage the internal Anode & Cathode connections of the cell. It will also start highly TOXIC electrolyte leaks that WILL do CORROSIVE damage to you & any way the cells are used, especially when charging. As demonstrated, this is the very best way to kill cells, or at the least reduce their capacity. SO GREAT CARE IS NEEDED NOT TO DAMAGE ANODE & CATHODE TERMINALS WHEN SEPARATING CELL TO CELL LINKS, as was done here.

what is the best way to remove cell from pack??
@@Rohitmbmee cut the tabs dont rip them
No, the main thing is getting the battery packs themselves. They don't just grow on trees by me.
*****
I like where I am at now. There is more to life than salvaged batteries.

No one is giving anything away in two, out of the three places you mentioned. So there goes the "free" aspect right there. I imagine you would have to be looking in the right dumpster to find 18650 cells too.
*****
you might not have said free, but the title of this video did. There's no place by me to look either. I live in a very rural area. I'm lucky I have Internet access today. For many years I did not.
yes you can get them a lot. but:
if u took it from laptop batteries dont expect to use in high amp required aplications such as electric tools in house building, drones, viping and more.
they are good for powerbanks, flashlights, toys, diy things.
if someone could say that earlier to me, i would be very thankfull for information.
you can find spec about the battery from numbers on it, and google it. most are 3-5 amp, some 1amp.
I stuft them in a electric power drill just do not over charge them respect the 4.2volt per cel limit. btw the drill is a 18volt en i made it a 24volt one to charge you need 25.2volt.
never fuck with battery safety when it comes to vaping.
paul horsburgh true that
And you can use your batteries for anything you want? Nice project.
I'm working on some projects with those cells allready, so stay tuned, i'll share when will finish it.
I use these cells for diy, power banks, flashlights lasers,...
vaporizers too?
+Robert W yes
for vaporizers to?really?vaporizers need a battery that have minimum 20 Amp for safety reason,specially those who do sub ohm and mecha or unregulated mod users for regulated mod that have battery protection it's not really maters because if you use low amp batteries the mod will not fire up it will says battery weak..so what is the amp that laptop batteries have?if it's lower then 20 Amp and you're sub ohm,using unregulated mod you will blow your face off..cmiiw
are those plastic boxes available on aliexpress?
This guy has more free time than an inmate. This guy busts his ass for those 1 amp cells
First, your home made charger is brilliant! But I am curious, why did you not use your sky charger to charge the batteries?
This is very illuminating - i didnt know laptop batteries used 18650's so i opened up a duff DELL D630 and I now have 6 new batteries for my new project!
Good idea using the magnets to hold the crocodile clips onto the batteries!
Check the voltages man.
I think that magnet idea was the best part of the whole vid and your info is so spot on
lol finger cutted from everywhere , i know how much laptop battery you have already opened XD
i got electricuted so fucking hard ouuuuchhh
I did this from an old laptop for a Chinese clock I couldn't get any because they were "vaping" batteries and I was underage. I get they're batteries but why would they restrict them where I tried to buy it. Thanks for sharing!
Great...but where to find Dead Laptop Batteries??
actually not just laptop battries i got scooter battery it was containing 20 cell batteries 🤗
you should discharge cells at 0.25c since thats what manufactures use, that 1000mah cell might have 1250 if you discharge it at slower rate
depends for what it will be used
They're not technically "free", are they.
18650 voltage between 2.75V and 4.2V. You discharged them to 3V only, however real capacity discharge is 2.75V. Then re-charge and measure the difference in mAh (Discharge vs re-charge mAh).
DO NOT USE THESE BATTERIES FOR VAPING. I know some guy out there will see this and think he can save money but it is not worth it when your mod blows up and you have to get skin graphs. Batteries are like $18-$30 for a pair, don't be cheap and stay safe.
+Christian P some of those 18650s he showed are ones you use for vaping he was charging it at one amp he didnt specify the amp limits but generally the lower the mah the higher the amp as the best 18650's for comping have roughly 1500 mah
+fuck you those batteries are taken out of laptops which have already been through some wear and those batteries are ran in parallel. They have 5-10 amp limit at the most. Still, unsafe considering you want a high drain 25+amp battery like Docan, MXJO, AWT, Sony VTC4, LG HE4, etc
+Christian P bro I'm pretty sure I saw some Samsung 25rs in this at least lol but I'll just leave you be since your obviously the battery over Lord of the world and can magically know amp limits on batteries that are unmarked and untested for amp drain to your knowledge go ahead keep making shit up
+fuck you they're laptop batteries run in parallel. It's not being a battery lord, it's years of experience dealing with computers and it's also not hard to take 5min to Google this
+Christian P well actually I did look it up lol most of those higher mah cells are completely safe at 20 amps and as i said usually the lower the mah the higher the amp so these seems pretty straight to use in a parallel mod at least
mAh and Ah which are seriously flawed unit (which doesn't take voltage into account),
which is normally used by manufacturers and marketers to misguide people !!
Professional and universal unit for energy are,
kWh or Wh.
I mean, these all of us use kWh meter in home, kWh in Tesla car,
and 1000 Wh = 1 kWh.
(how else simple do you want ??)
Still people use mAh and Ah, wonder how lame can they get !!!
And for comparison (different rechargeable battery types):
AAA [NiMH] = 1 Wh
AA [NiMH] = 2.5 Wh
AA [Li ion] = 3 Wh
C [NiMH] = 5 Wh
D [NiMH] = 10 Wh
18650 [Li ion] = 8 to 13 Wh (high drain to high capacity)
26650 [Li ion] = 14 to 18 Wh
________________________________
Average energy of Tesla battery are around 11 Wh [18650],
and to make a Tesla P100D [100 kWh] Model S,
= 100 kWh / 11 Wh
= 100, 000 Wh / 11 Wh
= 9091 batteries
or in simple words,
9091 [18650 battery] x 11 Wh = 100,000 Wh = 100 kWh.
________________________________
So i would seriously recommend 18650 enthusiasts to use Wh and kWh [our universal unit] instead of flawed mAh and Ah which are way too childish unit for energy !!
I've yet to do this without stabbing myself with the sharp soldered tabs. Interestingly - those snot brown ones are the best I've had out of Dell packs - around 2.8Ah each.
DON'T USE THESE FOR VAPING!!! These are PCB protected batteries that can deliver a max of 5 or 6 Amps. MAX !!! If you sub ohm on these with a mechanical or a regular mod, they WILL explode from overheating. But if you use them on resistances like 1.5 or above they will probably be OK. Even if you are on above 1 ohm, i still would not recommend these for vaping. In the vaping world, knowing your batteries is the first step from harms like burns or explosions.
Very impressive...but I've been reading some comments below will not use for vaping but really fucking impressive dude👍👍👍
So how do I get them for free? You showed how to take them out of the cases, but by then you have already obtained the batteries. That isn't helpful. What I need to know is where do these battery packs accumulate in numbers large enough to warrant asking for them for free of charge.
Good advice. In my experience, most lithium battery packs fail when ONE cell (or maybe two) die. If you disassemble the pack usually the majority of the cells are still good. I put them in a box and next time I have a battery fail, I check if I have anything that fits. Before I store them I use a 3 volt flashlight bulb and a couple of wires to drain the cell completely. That doesn't seem to hurt a lithium cell and it insures that any new battery assembled starts out with even charges in all the cells. I've also used lithium cells to convert old NiCad batteries to lithium. In most cases there is more than enough room in the old NiCad case to fit new batteries.
Step 1: short the batteries by putting aluminum foil across all of the terminals
That charger has magnet ends? That is so awesome. I didn't know that existed.
It's just crocodile clips with with some button magnets.
i found one laptop and dell battery module got 9x battery and 6x battery look like Zippo Lighters just waiting for my multimeter from ebay i want to make a cheap power bank found one it can holde 8x 18650 battery for 5$ i try find one is bigger but only one found can holde 8x battery
too old no use
Sir I have a dought where will we find those laptop btteeys I search hole area near me but didn't get those please help 😭🤦🏻♂️🙏🙏👍
I charge my 3.7v 18650 batteries with a 3.7v charger and they take a full day to charge why is this? (they are brand new)
Check out this Kickstarter campaign for an 18650 cell battery testing system: kck.st/2eUyaAR . If you want to get some real performance out of your battery packs, you need to use a system like this that is specifically designed for this purpose. The system guides you through the entire process of labeling cells, performing high precision capacity and impedance tests, and matching cells together using an optimization algorithm.
so one of the comments says they got 18650 batteries for $2 that they blow up did they last 3 hours...... no one has gotten into the statistics of lithium ion batteries nor where to purchase them probably because you don't get a kickback people on this don't do anything for free
since 5Ah made in japan 18650 batteries are $1 each, is this still worth while? ebay item # 262085265831
That is the worst way of dismantling an electronics component. Instead try to give a fuck about what you do. Like de-soldering instead of wiggling and stuff.
So how did you acquire the dead laptop batteries? Are they just lying around somewhere for the taking?
Hey...take a look at our new Kickstarter - it's a tool for measuring and characterizing new and old lithium ion cells! We'd love for you get one to try one out and think you'd find it useful! kck.st/2eUyaAR
where do I find those Magnetic Alligator Clips?
it's not wise to use batteries like that because it gives a higher chance for them to "vent" or explode.....use fresh batteries if you want to vape...I mean unless you wanna risk it be dirt cheap and possibly have a higher hospital bill instead of buying reliable batteries that haven't been tampered or messed with...common sense guys come on
Great video!
It's really dangerous use to vape this battery, vapers don't do this if you don't want explode your box mod or mech mod.
what makes 18650 battry cell easy to get overheating, when we connect to rotor, actually that's not short current!
I got many of these batteries the same way and use them for many diffrent projects.They make great back up power supplys
I just tried to open my old laptop batterys and cut my finger pretty bad thanks for the 'great' Idea
+TJ Houston Well you should have been more careful. You are the one that hurt yourself, not paying attention. I would have used mechanics gloves myself...
+TJ Houston Never cut or pry towards your body. Ever.
+TJ Houston Should've had a parent or guardian supervising you.
+Chris P. dont get bloody, cut twards your buddy.........
Hi, If I set the charge at 0.5a but the charging doesn't go uppen than 0.2a, this means the cell is gone?
please tell me i am in india and using hcl L1114 laptop ...battery is not working
Oh fuck, i have a huge stash of unsellable Panasonic Laptop batteries in my basement
Make a Diy power bank
Where can I get two 26650 Battery Holder like shown at 3:34?
Great video, great channel. WOuld you be able to link me or tell me what to search for the connecter that bridges your power supply to your imax b6 please?
Yes please! :D
where to buy these old laptop batteries?
I would not stick them in my mod. Even if I was too it just easier to buy them than all that polava
are these useful for toys?
DO NOT VAPE WITH THESE BATTERIES YOU WILL BLOW YOUR FACE OFF...!
very good video
Thank you
so you're saying those kinds of batterues are in old laptop batteries?
the 6 cell laptop battery for a Hp dv1000 is on ebay for $6-7 at the moment and the cells are panasonic CGR18650AF these any good for a 8 cell battery bank? or if anyone has recommendations for a 10 18650 cell battery bank?
ebay item # 262085265831
but where i can find some battery
can i have a adrese
My question is how long those "good" cells will last?????
Hey I did this and I'm using the 6, samsung 18650's I got from an old fell for vaping they work great but I need to get the small pieces of sharp metal off the connections I've tried everything and removed the wraps because they ripped. I will rewrap them before I use them so don't give me the saftey bs
do NOT use these in an ecig
Very Good Sir, I learned much. Blessings, pierre from New Mexico
Now we know how to get free cells .where do we get the laptop batteries
I have a non genuine imax b6 charger that when I do a discharge test using the lipo setting, mine won't terminate at 3v. It will keep lowering the current to keep the voltage at 3v. Does yours do the same? I found from another video to use the nicad discharge test and set it for 3v to get it to properly terminate at 3v.
+Aaron S mine stops at 3V and at same 1A of load.
Be cautious charging cells of differing internal resistance and condition. Li-ion cells are very dangerous if mischarged.
paulanderson79 he is charging them individually, what are you on about?
Having watched again yes, you're completely correct. I am still slightly nervous of combining multiple cells in different condition into batteries.
@@NGC1433 Don't. "Marry" your batteries if they are going to be used in something like a flashlight or laser. If one cell is discharged and the other isn't it will be really shitty. I have a few nice nite cores to charge all mine, be safe.
u have any 1865o which have 2200 may or mor that u can sand me for cash plell let me no or send me a link to eBay for the right labtop battery so I can get me sef
Wil u techie meh to English pls?
The dead battey can not be recharged ? I believe thats wat we do all the time to recharge the dead batteries ?
Not dead as in it needs to charge. Dead as in it won't charge and is dangerous to use
for anyone who uses Kangerteck subboxes to vape here you go free batterys
completely the wrong time of batteries for vaping with hahahahah
Ian Appleby hey if it works it works
They dont supply enough amps for vaping.
and thats how people blow their faces off in using batteries which have a way to low amp limit or which are old
yeah, minus $32,000 to have teeth put back in your head. Oh well.. at least by the time the wires come off your jaw, your nicotine addiction will be past. DUDE! HIGH quality batteries are like $15 each for 30amp 3000ma, why even fucking risk it?
The question is : how to get free laptop batteries ? 🤔
do it ! Junkyard ? 🤔
I've seen many of them in those 200 L barrels they've got.
I see .. but where I live I could not find them for free ...
do it ! Too bad then. 😮😯
Yea whoever said they get them for free are lying, no company is going to let you come on there property and take things without paying lmao junk yards should charge by the pound and it's dirt cheap
Are they rechargeble and do they fit in lazers
Will all laptop batteries have cells or will some be a battery with battery stuff???
Wh-what?
You cannot determine the capacity by discharging it from some random point! You need to either completely discharge/charge it to a know minimum/maximum and then you work from there to determine the capacity....
why you keep so many bateries.... send me some ..
Can i get the full amper of the li ion batterys
When you see what's inside a laptop battery you wonder how OEM manufacturers like HP/Dell have the gall to charge £80-100 for a 'genuine' replacement. Daylight robbery.
Terence Jay yeah fucking Dell. Cost me 1/8 of my laptop price for battery.
Perhaps if you spent more time learning business and how to make money... :)
mine has barely any volts what do I do? its like 0.1-0.02V
try charging it n then the testing
could i use them for my vape?
No
but they are dangerous to put in a ecig because they have no protection from bigger amperage and it can explode
+Matas Jo Most batteries have no protection from overamperage and NONE of the best vaping batteries do. The protection is in the device. If vape batteries are exploding on you, it's because you don't understand what you are doing, not because the batteries are dangerous. These batteries have a listed max amperage draw. Every battery ever made does. Mechanical mods have no protection at all so even the best batteries can explode if you use too little resistance which means massive amperage. If you don't exceed that, they should be safe for their entire lifespan. If you don't feel like doing the math to find out your amperage to match your batteries, stick to eGo devices. Even regulated mods can blow up batteries.
Are the Samsung ones better than the Sanyo ones?
Is it possible to charge them without your "special" charger ?
XTAR makes a lot of high quality but cheap chargers. The MC1 is cheap, the VC2 fun (capacity display), and the most expensive do 4 at a time.
Can you use them for flashlights
battery with code LGDAS318650 is categorize as 18650 battery? im confusing
it made me brake my lap top
Hello everyone
i opened old dell laptop battery and i got lithium ion battery 11865 not 18650. are these batteries is different from 18650???
Preyansh Yadav no shit 11865 is not the same number as 18650 is it?
They're probably LG cells. They are the exact same though, 18mm diameter and 65mm length. Don't know why they call them 11865 instead of 18650 but they're the same battery
Please give the link of battery
tell me!!!like you!!diagnostiese and cull plozhie the battery industry!!and how?write in English!!!I understand using a translator
when i destroyed my sister's laptop i accidentally broke the laptop's battery in half and i've found something weird, 6 18650 batteries inside! they were the light blue 2200mah ones.
I've put it inside my mod box and it read "battery unsafe". I was proud of my modbox.
Hello where can i so many liion 18650 battery get or from where you get so many Li-Ion 18650 battery thank you in advance
Where do you get the labtop batteries
You said it yourself, DEAD batteries, won't hold much charge
Sure do. I mean, if they're dead laptop batteries they must be unable to hold charge, right?
oook, thanks
Old batteries develop a very high internal resistance so it wastes lot of energy in charging and discharging ... reducing the over all efficiency of the cells... not a good idea to use in solar applications where u want to keep as much energy possible!
Laptop batteries aren't free or cheap!
i use the exact same charger as you.. Imax b6..
BTW... you read the Capacity/Mah reading wrong.
The charger is giving you the capacity readings from a half charged battery..
Do a capacity test from a freshly charged battery, for accurate results
Ok. Here is a question. Why check the charges on a battery before attempting a recharge? The 18650s are designed to be recharged. I explain. I have a buggy old laptop that I am ready to trash. I have 18650 flashlights for use in the house. Every few months, I check the charges anyway. If I charged up the old lap top batteries (assuming that each would hold a charge) and used them instead of what I am currently using, why bother evaluating them in advance.
So you get them from old laptop batteries? Great. WHERE DO YOU GET THE OLD LAPTOP BATTERIES? Jesus.
you could do all this work.. or you can grab 10 dollar samsung 25r's like a normal person. its really not that expensive. and will give you better power than some used one lol
this takes 10 mins. last time i checked 10 mins of work for 4+ batteries > 10$
Unless you have access to lots of potential batteries, this is not worth the trouble. Some stuff I salvage, like relays and transformers, but for perishable stuff like batteries I buy as needed. Time is money, and the time wasted on gathering, testing, stockpiling and maintaining nominally performing batteries is not worth the cost of purchasing new ones.
you group you cell, that's mean you can parallel one group of cell, looks the difference between group of cells is 500maH for one group for another is 400mAH and for the last one is 300mAH
Does most laptop batteries have the 18650s?
Most but not all for example Macbooks have flat cells (not sure what kind). These cells are useful for other projects, I converted a RC transmitter to use the cells since it has a super low power draw.
