- Today, let's investigate another 3 good looking, but still relatively cheap 3.7V 18650 Li-Ion rechargeable batteries from Ebay. They are rated 2500mAh, 3000mAh and 3400mAh. What's the actual capacity?

“15kg explosion-proof etc.” We need a test video on that 😏
I like your reviews because they're in-depth and exposing, thank you :)
Another good video of what to look out for when buying 18650 cells . You must have a lot of patients charging discharging all of these cells - please keep the videos coming.
That LG battery description gave me cancer
Xd
Interesting video. Like you said, capacity was way less than advertised, but cells are still usable in many applications.
Great video! You are the best electronics youtuber.
Your a great informant on this subject . keep the videos up mate.
6:32 they're so vague on the "lead to scrap" bit, the image that popped into my head was that if you don't charge the battery, thousands of pounds of scrap metal will be dropped on your house in the middle of the night
A lot more clued up on 18650's thanks 2u. Love the Dracula accent keep up the good work 👍🏻
Highest capacity batteries right now are LG INR18650-M36 and Panasonic NCR18650G which are usually quoted as 3600 nominal, but really under realistic discharge currents they're indistinguishable from 3500. I think both are specified to weigh 47.5g
The first two of "mysterious numbers" on brown are LG, which (if it's not a fake sleeve - which it stands to reason that it likely is) would indicate where it came from, that would be an INR18650HG2 with a 3000 nominal capacity.
"Do not modify" seems like they're challenging you :D IDK, sleeve replacement, top piece replacement, poking inside the top with a needle to reset the pressure fuse if blown?
INR18650-25R is specified as weighing 44-46g, the INR18650HG2 doesn't have nominal weight but max is specified as 48, and the NCR18650B is specified as 45-47. Unless your scale reads consistently low by a couple grams, it would make all of them likely fake - unless they lost some electrolyte. Does that happen, do rechargeable batteries lose weight with time to a tune of a couple grams? I wonder. Besides, i don't think the top of the NCR battery looks like it would on the original unit, you expect super sharp stamping with very little roundness, fairly shallow, and the white washer having such a narrow opening that you can barely see the slits at all. Probably worth looking up what the tops of other batteries, if they were original, should look like.
These videos are very helpful. Thank you!
Back when I was vaping I used these 3 particular types of batteries, which I bought as new and they costed between 10 to 18$.
The one made in Japan, 3400 mAh is from Panasonic, older generation, high capacity, moderate discharge current, it wasn't very good for currents above 5A.
The brown one is indeed LG (particularly HG2), really powerful for vaping, very high discharge current, it lasted for quite long.
The Samsung one is the general purpose battery which came with my vaper. It was OK initially , but indeed it did not last many cycles.
I tried to test their capacity as new by discharging them with a 10 Ohm resistor and by measuring the voltage and current every 15 minutes until they reached 3.2 V and back then I came with these numbers: ~2600 mAh for Panasonic, ~2500 mAh for LG and ~2000 mAh for Samsung.
I guess the ones from the video are not fake but used quite well.
I laughed so hard at those descriptions especially the "maximum downloads" 🤣🤣🤣
Genuine Samsung 25R and LG HG2 are popular mid range batteries used for vaping these days. The 3400 mah Panasonic is popular for flashlights but usually prefer real button top and protection pcb for those applications.
Thanks Danyk for a very interesting and informative video. Could you add web links to buy Li-on batteries?
when i took a bunch of 18650 cells from old laptop batteries, they usualy were about 0 volts. i just plugged them to bench power supply, and charged at about 1A ( loocking if they aren't hot). and now i have about 250 of them with capacities from 1000mAh to about 2500 mAh (average about 1800 mAh) for the price of about 25 cents/pice :)
Even more chipper than usual diode?, could almost feel the happiness in your voice... you've been at the catnip again haven't you? 😎😎😎👍👍👍😂😂😂
6800mah is true, i tested it with my perpetual motion machine. ;)
That is micro amps. Chinese confusion in translation.
@@skipperrussell2025 Think before you write. :-)
Hi Danik,
At 14:00 when you show the bottom of the three batteries, I thought I saw, when the point of view was more grazing on the metal surfaces, that the bottom was slightly deformed in some areas, as if it had been filed and then brushed , to remove the welding points, perhaps the battery falsifiers have gone to a higher level of sophistication than the double bottom with a metal disk, unless they were visual artifacts due to the compression of the video ...
Hi and the next videos
P.S. LITOKALA is a brand sold by Banggood: in their advertisement they say that their batteries are 100% original, but when they arrive, under the brand (a sticker on the green plastic) they are branded SAMSUNG !! I have not done endurance tests so they could also be good ... but can i say: what ?!
This video was rated for 80% Cat but we only got a miserable 15% Cat. Need more cat next time.
Yeah
more cat
Obviously used/repurposed cells. Thos INRs usually cost 5-6EUR brand new so 3.6USD incl shipping is what you would expect from heavily used ones...
Hi,Please try to make a teardown video about smartphone fast charger...
fast charger,like Qualcomm rapid charge/Samsung Adaptive fast charging...
When are you gonna make that video about that new stun gun module you ordered?
;) greetings from the netherlands
I completely forgot about it :). I hope I will do it soon....
Goed idee makker
are you sure your measuring works? do you have something to calibrate or did you (ever) find a battery which has the capacity which is claimed by the manufacturer? :)
Great video!
You could test Litokala 18650 or 26650 li-ion batteries from Hong Kong, they cost too about 4$ including shipping, but it is possible to buy them from Manufacter, not only from some random Reseller.
I have been buying Litkola from Likola Official Store on Aliexpress, they are priced very competitively and check out exactly as described , very good
Very helpful video. I like it 👍
Great video, thank you.
haha .. coincidentally I just bought the same solar charger and I am quite happy with it .. I use it for my powerbanks and have only minor nitpicks about it .. I am getting about 8W of power from it most of the time due to real world circumstances ( it's rated 14W peak solar power) .. now I need to search for your video on it and see what you have to say about the panel :)
They don't want you to modify . no soldering tabs for making bridged in line power packs . because of the heat exposure applied to the batteries . but I love to know in your opinion what the best brand and highest rate batteries for high power lasers . as I want the best ones for my high end lasers. Thanks diodes gone wild.
You are very informative and hilarious 😂 👍
Can you review the Samsung 36G battery which is 3600mah? It will be interesting if it is fake or real.
For product liability reasons I imagine the battery you’re showing would be said to have been modified if it has a nickel tab spot welded to it. In a way, that warming is a good sign because it indicates the manufacturer has a product liability insurance policy that requires that warning. It might also indicate the manufacturer is using processes approved by the insurance company. Therefore, modification is possibly safer.
Is yiure testing device good? I use a liitokala engineer lii-500 that works perfect
greetings from Brazil to all. 11:06 Look at who showed up. the helper Cat. 12:00 always right too. very good to know. Congratulations on your work. success.
You should have also used a proper intelligent battery charger. Mine is the BT-C3400. Each battery needs to be discharged and recharged three times before using.
4:37 I'm waiting for the review of the fleshlight xD
thanks for testing! Little bit long the part on the "Cinglish" - we all know how funny the translations are and most often very disleading or confusing! To be sure about the specs one should always look at the datasheet of the manufacturer of the battery :-) The batteries look very promising and could be real - but its good to know they are still fake or used ones or old shelfware with lots of capacity loss! Many old cells from old laptop batteries are still better and much more safe to use i would say! In me experience you can find good cell even with very low voltage above 0, like 0.5V can be still good. But when they have reached 0.0 or even negative they will be really dead or leaking a lot. This holds esp. for high-current cells.
What do you do for a living if I may ask?
Have you measured max output current?
Another thorough video from MR Diode. Would it be possible for you to show the seller's names on Ebay that you bought from? It would help others to identify and avoid or even go to if good sellers. Thanks for the work you put in.
Those are from sellers called jade-marginjewelry, onepiece2018 and greenteatime2016 (in order from left to right).
@@DiodeGoneWildi know it's a 5 yrs comment but those Sellers' names should be pinned in the comment section
And of course the total capacity is the capacity that we do not have access to because of the voltage drop limit. We only get access to about 70 or 75% I think?
some 18650 batteries actually have built-in pressure release membrane which releases high pressure and disconnect battery from rest of the circuit when something gets wrong with the battery but after that is battery useless it just should prevent an explosion
Because of you and your work i will buy thay pirl charger
I have those litokala ncr18650 ... all of them come out to be 3400mah to 3500mah... u should test those with your tester ... I used readymade Chinese capacity testers... buy litokala and u will see it!
Yes, I was just going to ask for test of Liitokala 18650 bateries, they can be bought for nice money, and i had only good experiences with them, even the one with the protection circuit really have it. And the fake LG HG2 seem's to work also fine
Can You check battery from aliexpress called liitokala?
They have pretty good reviews even with checked capacity but i dont know if i can belive them...
Can you measure the internal resistance of the batteries?
Good vídeo. Tank you. My big like for you 👍🙆🙌🙋👏👏👏👏👏
I think the mystery charging current is pulsing charge or pulsing discharge?. That's what vaping devices do!
I have those real LG HG2 bought in czech stores and the specs are kinda messed up, it is for 20A discharge. I have 4 of them for SMOK GX350
Tiež som tie LG batérie dostal ku Voopoo drag 2, ale ťažko povedať, že či sú to originály, alebo nie.Vedľa toho značenia na batérii je niečo podobné, ako QR kód (ktorý na batérii vo videu nieje), ale ťažko povedať, že či je to známka originality 😀
20amp 3000mah
I also have one of those LG HG2 batteries for my SMOK Al85 but when I tested the battery that I got for it when it was brand new, the battery only gave me 2700 mah
Samsung specs for INR18650-25R states: “Standard charge: CCCV, 1.25A, 4.20 ± 0.05 V, 125mA cut-off”
For the LG the manufacture states: “Charge (CC/CV): 4A charge to 4.2V, 100mA cut-off”
Is it possible to check if that charger meets the specs?
I already knew that Samsung 25r was fake when I saw that 0.05v voltage drop on just 0.5 amps.
That third battery supposed to be a Panasonic one. Original Panasonic batteries supposed to have 4 spokes on positive side, yours has three. I have one or two of these, also with three spokes, but with proper capacity.
that cell is supposed to have 3 spokes
If the price of these comes down a bit more they might make a good replacement for a 125cc lead acid motorcycle battery. At least on paper since they li-po should last as long.
I risultati non in linea con le specifiche del produttore potrebbero dipendere dai 3v target di scarica, laddove magari il produttore per decidere la capacità della batteria ha un discharge cut-off di 2,5v (Samsung per esempio fa così).
These are probably lower cpacity cells re-wrapped as high capacity/current cells.
The INR18650-25R should weigh more, due to the higher rated current.
So should the Panasonic, due to the sheer amount of capacity.
How can a 18650 handle large current without exploding ?
Don't you know LG and their reference numbers? A website you can easily find the datasheet of each battery on is called Second Life Storage, which as its name says has been made for people taking cells out of dead laptop batteries to give them a second life!
How can these be 25A discharge cells? They only come in 10-15A for discharge
Ready For Loading And Unloading! ™
So what do you think: are they fake or original but used batteries?
How do you know if a cell is protected or not
So where do you buy good 18650 batteries on USA?
You got a fake NCR18650B 3400mAh 3.7V lithium battery. Mine charge up perfectly and are 70mm high, weight is 48.5 Grams. Each cell cost me $21.00 each. I got what I paid for.
18650's storage voltage should be around 3.5 to 3.55V and that's the voltage all the HB6 LG cells came to me in a big box. There are not many studies about this topic but lithium ion tends to have lesser capacity loss when they are closer to 0% SOC but not in 0% SOC I hope I got that right(non english guy). Also lithium ion are made to degrade less when fully charged in typical application but they will lose capacity anyways. Lipo are whole diffrent story I had aquired some ranging in age from 1-10 years and I also did some experiments with storage. In lipo maintaining temperature and 40% SOC or 3.85V per cell is crucial there to recover almost 100% of capacity, you go in any direction, less or more - they suffer a lot and worse than lithium ion. I had some 25Rs(genuine) stored at 40% SOC for 4 years in 25 celsius and according to data I could find indeed I was able to recover up to 90% of their capacity but I also had seperate control group which were charged up to 3.55V per cell and left in storage. In case of those I was able to recover from 95 to 97% of their original capacity. I also should have mention that both control groups of 10 and 10 cells were fresh and never used. I think my test group of 10x10 is big enough to prove my theory about storing 18650s. I own several M12 brushless milwaukee tools but I don't use them regularily so usually after some big projects I discharge all of the batteries so they stay around 3.55V per cell if they are going to stay in the bag for 1-3 months or sometimes. While some of my coworkers are now complaining about their multitools M12 not accepting batteries which they all the time store in the bag fully charged I don't have problems like this and my batteries are performing really well. But I'm doing that little sacrifice when job is done and while I drink some good czech beer I got my ass up to hook batteries to electronic load and set it right then it does it job while I still enjoy that beer, then I can just put those batteries in the bag knowing they will be good.
I didn't know downloads could be measured in amps. :)
I have a fake 18650 UltraFlrc battery, but i has many used 18650s.
Has anyone noticed the Eminem folder in the taskbar?? xD Love your vids
best 18650 battery for vape ?
8:28 maximum downloads🤣🤣
Is this an old edition?
The terribly translated descriptions are so hilarious
Those are used or rejected cells. The Panasonic NCR18650B batteries are the best one you can buy, just find original legit sources from Europe or USA.
Lets assume cat knows everything
I have same old cell 18650 from notebooks batteries. Capacity 1600...1800mAH.
It's very strange. These batteries appear new but are very weak.
Some time ago I bought 50 laptop batteries for $ 1 each, and there were usually 6 cells inside. 30% of the batteries had over 3.5V, 20% over 2.5V, and the other less than 2V (but even 80% came back to life, thanks to the charger with the low voltage cell rescue function) and they keep the voltage and don't heat up when charging. Half of them still stored around 2000-2200mAh.
my cosin said that you are amazing in speaking english
You should call this episode : The best of “Chinglish".
No, It's Czechglish, believe me.. with strong Prague's accent.
racist are normally not very informed
@@eyeswideshut2800 it has nothing to do with racism.
Love that Cat!
Wow. I live in HK and I buy legit cells for about 2-3usd depending if they're new or salvage
They are used rewrapped for sure, polished bottom.
The Li-ion battery 18650 is being tested for capacity with the final voltage of 2.5v and starts at 4.20v and discharges with 500mA, since it was not so tested, it did not show the right capacity at the end. These batteries (all three) in the video certainly have over 2500mAh minimum (not 1700-1800mAh) and this will be seen when they are properly tested next time and are probably original and good only you have to test them properly another time... 😏 !
Aren t those small power banks getting very hot because mine does :/
Indeed, the capacity is often overdrawn.
Which is great?
looks like most these random 18650 cells end up being either 1700 ~ 1900mAh or crappy 600 ~ 800mAh
Always thought 8:47 maximum downloads were 4.20A
I see a cat, I subscribe.
when the next videos will come ???
be neat if you make make a reachable nickel metal or lithium ? lead acid motorcycle replacement i need to build something for an old Honda 1974 cb360 cafe racer geting rid of lead acid
You need to have a charge and balance controller. Is your bike electric start? If not, then you really don't need Lithium, you could almost do it with super capacitors.
I thought they only write down the max discharging ampage. Which would be way too low for my uses
The brown one seems to be a LG cell BTW
Try liitokala cells from Aliexpress
got some ncr18650b from them there where original (capacity was correct, weight also. and top pole had 3 wings not 4..5 like fake ones)
they're very hit and miss. Some are fake and some are genuine but they all have good capacity usually but the fakes you know because of the high internal resistance. I would love to see some tested
I got some from there. But beware, there are a lot of litokala shops on AliExpress
BIG RESPECT DUE to you buddy.. ty for a non fake review .. we know who is the prominent rip off country, who must think we are all stupid people. What an insult eh ? TY

I'm gonna to guess that the first and third ones are real and the middle one is fake.
I have 5 of these Samsung 18650 batteries and 2 have failed for no reason.
My guess is the cells are just old cells that never sold & likely lost capacity due to improper storage charge (too high or left in storage for too long). Then someone bought them in bulk & listed their "rated capacity" as the capacity of the cells--rather than individually testing them to determine what their actual aged capacity is at the time of sale.
That's why I think it should be legally mandatory for all li-ion cell manufactures to engrave the manufactured date on the bottom of each them--otherwise unscrupulous sellers on ebay can sell unsuspecting people junk inferior cells.
There is a shortage of Lithium batteries. They never ever "sit around never sold" long enough to lose capacity. These will be low quality cells (lots of those out there), or used ones... re-wrapped.
The Panasonic cell in the looks like a real Panasonic cell. I doubt Panasonic would sell low quality cells. There must be another explanation.
panasonic/sanyo, sony print the date code on both the wrapper and metal casing.
@@Jeff79z Not that I've ever seen can you show us an example of that code & how to decode it?
8:40 please kindly understand
More FLASHLIGHT autopsy please. Have a nice day😀
I will review the flashlight with its dodgy charger soon. But before this, I have to take a look at the 5V 2A power supply. The person who donated it is waiting for it a long time already...
