- A quick measurement to spot fake copies of li-ion cells.
Samsung, Sony, LG and Panasonic all publish cell specifications. Use just one of these characteristics to determine whether you have a genuine cell.

Useful information but PLEASE get a better camera. How are we supposed to spot anything with everything blurry!
You are awesome sir
Big heart respect to you for giving us insight of electronic for students like us to get lists of useful knowledge
Thanks once again
What if internal resistance and capacity is the same? There is bunch of feedback with capacity test and it seems to have good parameters
This video was uploaded on my birthday, so I know it's a genuine video.
Can you recommend a store on aliexpress where you bough genuine or close to rated capacity NCR18650 batteries?
Where can i find this barcodes checker site? Thank u!
Thank you for the video and information! :D
Love your videos, very imformative. Could you provide weblink to where you source your 18650 cells for $2, and can you get them from the UK? Many thanks
Very usefull, just starting out on the build your own battery path, the pitfall isn't technical its the starting out with duff cells in the first place. All we are left with is internal resistance on pre buy batch so be it and thank you for providing that gold dust for the rest of us.
It seems to be the fact that New 18650 cells have a higher internal resistance and after a view cycles it will drop. This information comes from trusted EU retailers and Nitecore (charger info and Battery). How is your experience to that ?fact?... Thanks for this video anyway!
Good video im ordering one of those mc3000's right now ive been looking for something like that with pc control and real graphing and specs
Hello Tom: I need to buy cells Sanyo/Panasonic NCR 18650 GA, 3,7 V, 3500 mAh. Was gonna buy them on Aliexpress, "Battery Pack Store" (USD 1.89 per cell), but reviews of customers said that they have only measured 2450 or 2000 mAh instead of 3500 mAh. Also it says "Made in China" instead of "Made in Japan" on the batteries.
Where to buy Sanyo/Panasonic NCR 18650 GA good price, safe and not fake, would you know? Thank you.
Great video, thanks.
*Thank you!!!* 🙏🙏🙏
*Question, where did you buy your real 18650?*
It is hard to find a reliable seller
This video is very timely and spot on. I have purchased cells from Ali sellers on numerous occasions, as well as lots of other items. I have become pretty proficient at the dispute process, which generally works. Recently I purchased a handwarmer listed as 10,000 MAh, and although that tested out to 5,200, I did not bother to dispute as I knew it would be impossible to sell a 10,000 MAh handwarmer for $11.00, and I just wanted to rebuild it with proper 21700 cells, which worked out well. But you have nailed the feedback. I also noted that their system is rigged, and seems to cull the negative feedback. Your advice to 'test' every seller with a small pre-purchase order is spot on.
That is normal in china.As a chinese,I want to tell you It's not easy for a foreigner,even a native chinese to buy something with really good quality and low prize online.But we still like shopping online.Because the price is really really cheap!Such as this 18650 cells.You can get a real one less than 2€（include shipping fee）in taobao/tmall/pdd/jd（online shopping app for everyone,The express was really fast,If you are fortunate enough,You can get the product less than 6 hours.And the price was cheaper than local shop）.You can also buy a fake one less than 0.8€ in Ailbaba（a app for trader to wholesale,All the products are at wholesale price.They also sell the real product.You have to pay extra fee for shipping,between 1€ and 2€,They will send to you your home in a week）
Whats more,ail will never rig the system,but the seller will.However if a shop have fake feedback,they will be banned by ail.But as for fake products,it seems that ail hardly ever care about selling fake products Because every buyer have ability to recognize what is real and what is fake.

What I said "feedback" means Sales and Remark.Some shop will hire many people to buy their products,and give five star remark.The seller will Pay the money back In another way.And send them an empty mail to cheat ali.
do you have any source or aliexpress link for genuine 18650 sony/panasonic/LG 3000mAh or more?
I dont think there is any
Can someone tell me what's the amperage of this particular battery? I'm not talking about the mAh, I mean the amperage in A, this is an essential info for vapers.
Really helpful, gonna buy some sketchy batteries off AliExpress and test them, fingers crossed! Thanks!
Do you sell ebike batteries Tom? Its just that you mentioned you're buying these in the thousands.
Love your testing equipment could you share gear by make and model so I can acquire them?
Cheers.
good job! and thanks for sharing. just ordered 6 of them on ebay from seller who claims that selling genuine NCR18650B Panasonic with actual "tested" capacity of 3400mAh/each. So will see. Also got a XTAR DRAGON VP4 Plus Smart Charger to charge these batteries which actually will spot fake vs real.
what happened?
Where they real or fake ?
I just bought exactly the same model from eBay.. what were your results?
Hi Tom, great video. Should I do anything different with a button top pcb?
Sometimes 18650 button tops have a BMS protection PCB under the covers. If not then you're fine.
Hi Tom, I'm on the look out for some 18650 upgrades. These batteries were one of my interests. Do you have a supplier for these genuine Panasonic cells where I can purchase? Thanks.

I just ordered 10 18650B from a Seller on AliExpress and all the batteries have a capacity of around 1800mah. I’m super frustrated cause I waited two on the for these. Do you have a way for me to purchase some real ones?
Tom, BTW, did Ali Express uphold the dispute? Did they take your word in the comments, or did you have to make a video? (I've found that I've usually had to make a video to get a successful resolution).
No. They rejected the dispute and paid the seller despite video evidence and "Platinum" buyer status.
@@crazytom
Thanks, that's something that is good to keep in mind. Over all the years I've been dealing with them, I've had to submit a number of disputes. In fact I just had one resolved yesterday over one of those common battery holders that you use for testing cells. Most of the listings say '21700' as one of the cell types, but you cannot fit a 21700 cell into them unless you take it apart and modify it. So, although it was only $9.75 with the additional shipping, I decided to just submit a picture with the dispute. They accepted it with no further questions. I seem to recall having one or two disputes that they did not accept, and I get the impression it sometimes depends on how well the person viewing it can actually understand the problem. I'm also guessing they look at our purchase history and see if it indicates the account seems to launch disputes that exceed some metric or mean that they have established (I'm guessing that over the last 5-7 years I have spent between 10-15K spread over hundreds of orders, most of which have been fine). It could be as simple as if you account history shows you are below their established mean, they are more likely to allow your dispute?
@@MountainParameters yes I'm sure they have a complaints "dashboard" that helps them decide if you're vexatious and I agree that it depends on who adjudicates... sometimes a refund with little fuss and sometimes rejected despite overwhelming evidence. I really cannot trust this process as I'm pretty confident I'm not the only one complaining about a product fault. Ali knows this and only they know this data.
I spend ~$4K each month with them.
@@crazytom
Sounds like we have a similar outlook on things, thanks for the comments. Over the years you tend to find some trusted sellers that you patronize. In the meantime you're trying to minimize potential losses by not ordering anything too expensive. And actually, as an update to the previous post where I though I had received a bad batch of NCR18650B cells, I noticed the load tester was not reading voltage properly. I checked the leads and it was not due to them. Once I corrected for the voltage problem, the cells appeared to have 3100 MAh at a 3V cutoff. So in this case the problem appears to be the load tester (from Ali of course), and not the cells after all. Right now it appears as though the only legit way to get cells shipped to North America is via UPS and perhaps DHL, and my supplier has indicated you should aim to ship at least 10kg to make the resultant shipping costs per cell worth it.
@@MountainParameters Yes.. I always check across multiple electronic loads if there is an anomaly. I ask all suppliers to ship DDP (Delivery Duty Paid). About $65 for the first Kilo and around $25 per extra 0.5kg IIRC. That way they sail through customs and import checks.
Code on this supposed "genuine" Panasonic ncr18650b is ECV 2021
The code checker you mentioned doesn't accept zero as second digit. Does that mean this is fake?
Correct. I should have mentioned what the format was.
Great info
I'm not disappointed that the listing was taken down. It just goes to show that Aliexpress are listening to you. However, it is likely that the seller will be back under another name.
I'm having the same problems with silver oxide button cells for my watches. There are so many counterfeit cells that it's hard to tell wheat from chaff, and it can be even tougher to work out which is which, that it is with the 18650's!
can i charge and discharge at the same time this battery, i like to use as continues power supply for my camera
Yes.
@@crazytom thanks dude, continues charge affect this battery?
Like others have mentioned, it would be really helpful if you could please link to any resources references or used in the video: others want your suppliers :) I'm ore interested in the tool used to monitor the battery while slowly discharging it (NC5000?), and where you were looking up the codes on the batteries. I'm surely someone else could appreciate your multimeter type, as well. Thank you!
SkyRC MC3000. It's the king of cylindrical testers but it is $100
1:00 i brought from Ali 2 of this greens under Litokala name and they are good; in flashlight they keep the strong light for 3 hours easily
Thanks. Just got some fakes on Amazon and half of the four arrived at 1.0v SOC. Sigh. No QR codes on them, and they are button top which I don’t think is stock for ‘NCR18650B.
Nice video, but darken the place a bit. The screen of the appliance cannot be read.
let me guess the battery which is from 2016 is fake, coz it is 3 years old )))

Could you tell the name of the app?
Decode 18650
Wow, he spotted fake, Wow. Have you ever heard word "datasheet"? Try to find internal resistance there, you'll find resistance "UP TO" so, 17 mOhms looks more likely. Before making any assumptions about fake you need to learn little more. And btw, most "fakes" on aliexpress and others are not fakes but unconditioned goods from same factories stolen or scrapped for bad production. Whole butch, but it doesn't mean all of them are bad. It could be good parts but doesn't fit this part number no more.
I had the same experience. I have bought 200 cells panasonic 3400mah but end up with 1100-1200mah. So I have tested all of them and showed Aliexpress the proofs and guess what they told me in dispute: If you dont like them resend them back to the seller otherwise no refund... But thats not possible bcos cheapest shipping EU to China is about 80$ per 1Kg if they even allow you to send batteries they are special dangerous cargo. So I have lost the dispute but at least I have 200 shitty cells hah...
Shocking.
Robert, I have done the same, but got lucky. The one thing I did do was go through the forums such as Budget Light Forum, and there was an Ali Seller on there that many had tried and tested. I've used that seller twice for large orders: one for 21700 cells and one for 1865 cells, and they have tested to spec. Now I am going to go off and test a bunch of the cells that I still have have previous Ali Express purchases based on Tom's information here, and keep my fingers crossed.
@@MountainParameters Well hopefully you gonna be lucky.
@@robertzeman4301
Thanks, I tried an NCR18650B last night before bed. I think it reported something like 2400MAh. It may be about a year old, and has always been charged to 4.2v. I think I need to find a charger that I can set to charge my cells to 4.1V. If anyone can recommend a charger that can do this, that would be great.
@@MountainParameters Well Im using Liitokala Lii 500 and Im pretty sure its the best one. You can see rough inner resistance and do Nor test which is charge, discharge, it never failed and I have bunch of them second year. Btw there is also new clone Fikida F4 dont use it ever! I have 4 of them and 2 burned instantly and last 2 are not working properly at all, only at 300ma loud and even that is very wrong. But if you want specific voltage you can use battery capacity tester ZB2L3 (HW-586) Aliexpress its like 3$ from China (2-3 months if you even get it) or look locally. If is not enough for you look for battery capacity tester 150W or 180W or 200W etc its about 20-40$ from China but the basic version 150W is good.
how cheap is too cheap?
Less than 6 bucks
Yes i have i device for measuring battery cells wtf
I think this guy buy his tops from the same shop as James May. 😁
lol !
Amazon is not such a great retailer either lots of their stuff is junk with thousands and thousands of four and five star reviews but it's junk....
You need some camerman instructions. Good video thou.
Learn from my mistake. These Panasonic NCR’s are some of the worst batteries designs ever. I should’ve read the spec sheet before buying them. Bought 4 of em, all tested to within ~3400 mAh twice, so they were real. Problem is... they have a storage temp of 50°C (122°F). They were used in a headlamp that was inadvertently left in the back seat of parked car. Headlamp wasn’t exposed to direct sunlight but it was summer time and the car can get really hot. Anyways the internal protection layer (aka safety feature) disabled the batteries. All 4 of them showed 1~0 varying volts. The jump start trick with a fresh 4.2v battery for 10 minutes didn’t work. Voltages would drop down to near ~0v immediately and no charger would charge them. I had them for a couple months. They were good and had lots of power but I will never buy these again.
They're used in Tesla model S (with a modified vent).
They’re used in select Panasonic Toughbooks as well. Lithium ion batteries don’t do well above 45C (despite what Panasonic tells you) so the issue won’t be specific to the NCR.
Just bought some from AliExpress . Hopefully they're real
Get ready to get fakes
VariCore ML12010 NCR18650B battery's are also great battery's, also real 3400Mah.
