Testing more 18650 Li-ion cells (REAL vs. FAKE) 

Naming a battery TrustFire is like naming a car DefinitelyCrash

I like your videos. Both informative and entertaining. Keep up the good work. Cheers, KC

hahahaha. I also got this type of battery. I bought one power bank from the local market. Really it was so funny for me

What are the brands of good batteries ?

DIY BATTERY ANALYZER is obviously homemade, I wonder what else you have.

it's things like this that are the reason I never trust any batteries. I just power all of my electronics using three hundred thousand potato batteries instead. I grow them in my basement.

trust fire= trust me you will have fire!

It's kind of funny they are marked mAh when they are above 1K m.. I mean it could just say 2.5Ah intead of 2500mAh. It's like if I live 600 meters from the nearest store, I'd go around telling people I had to travel 600000 millimeters to get milk.

I guess you can trust fire?

3:20 Do not disassemble the battery or put the battery into fire The battery must be charged according to the charging requirements Do not place the battery below 2.75V

hello dog :D the dog is not so curious about electronics as the cat. cat always wants to know about the experiment being done. I think dog is just waiting for its dinner or go for a walk.

Lol, love the magcian's presenting voice. Sound like The Count, I keep waiting for the, "And today's show is a brrrought to you by the number 3.7! Ahahaha And the letter V! ahahaha" lol

One apparently also now has to be careful about relying on cell weight. I've read of some manufacturers packing sand or other compounds in low-capacity and/or counterfeit 18650 cells to make them appear heavier and thus closer to the expected weight for a higher-capacity cell.

What you say in the description is wrong, 3600mAh is still possible!

Ther is some rezistrrrrr in itttttt

I love the accent its nice to listen to

those fake 18650 battery contain a smaller battery with 900/950 mAh capacity and some sand to fill the empty space

Hellooooo! Looks like I'm earlyyyy (Not making fun the accent just amuses me)

Danyk ! You cant hide with that voice :D

Will you please teardown a charger like iMax B6 or Accucel - 6? And explain how it works?

Your speaking style is good to listen :) by the way where is ur kitty :P

I've enjoyed following this series. You start wondering with the 25kg/500mHa fakes if there is a single factory that makes those specifically to be sold on ebay under a myriad of fake brand names.

Thank you for the tests! It sucks indeed those fake batteries are sold!

The batteries will last longer in long term storage at about 3.5 v. This is less that full capacity. At full capacity they degrade faster. According to manufacturer literature. This rule is valid regardless of the size capacity of the battery. Before use, after long term storage, the batteries should be topped off to 3.82 volts. The 3.8V is good when a person is recharging and using the batteries on a regular basis.

40 amps omg 😂

12000mAh in 18650 package, that is hilarious, i don't know for what kind of people it is targeted so much of bullsh*it . BTW nice doggo ! :D

never trust in trust fire. hes lie

Lo maximo que puede tener de mAh una 18650 es 3500 mAh como es posible que las fake pongan 9900 mAh y las personas se crean esto y las compren 🤣🤣 es ridiculo

Clearly the high capacity batteries have helium as the special ingredient to give them the extra capacity

kok bingung mbek bosone aku mek paham titik2 😴

6:54 "DoublePow" ... LOL! Double the POW! (BANG!)

Chinese translate：Do not disassemble or burn it.And charge it properly.Do not charge it less than 2.7volts.

Is it still possible to get these things shipped to EU countries? The last time I ordered 18650s and some other batteries they just don't arrive so I'm thinking at some point someone notices them and stops them from being shipped, I could use some cheap cells because the capacity is not really an issue and the good ones are ridiculously expensive

Yes you are right, the ones advertised with capacity amounts greater than about 3500mAh are probably fake batteries. No manufacturer has gone above this amount i don't think! mainly due to cell size Limitations.

i have 1000pcs of HIGHSTAR isr18650 3.7V and 2000mah.. does somebody have any data about this cell? because i need to testing them.

6:22 No to vidím, že to je falzifikát, mám 12V batériu, ktorá stála cca. 15€ a má kapacitu 9,8Ah (9800mAh). Nie je možné aby monočlánok mal vyššiu kapacitu ako 3S4P batéria...

The real capacity of Chinese batteries is advertising capacity divided with 10 😂

Would you say these fake marking battery's are made with 100% Criminal Intent? If so this should be investigated further do you think?

I was taking out a battery from a small power bank, and we forgot why we don't used it. Because the battery was super bad. The ICR18650 D1 battery claims, that has a capacity of 3000 mAh. I measured it, and it was just 125 mAh!😬 The battery was just 6 years old.

Good video thanks for Thanks for contributing basically those fake battery are the same you just add new name and done.

Thanks so much for the listing of all of those 18650 batteries because I've only purchased 2 from Ebay, & of coarse they were fake. At least now I have some much needed info before purchasing any more thanks to you. Keep up the good work my friend. Do you have a video of where you built your battery tester at??? If so could you please send me the link to it here? Thank you very much, Tom.

TESSON are the best relatively cheap 18650 Batteries I discovered so far. They deliver high current without significant voltage drop and has reasonable capacity. There will be no counterfeits arround cause they are not famous enough for that.

You should never get to 3.3v with Li-ion cells. Not even for short periods. Even 3.5v makes me cringe a bit. 3.7 is my desired minimum voltage.

Would be interesting to also test the high current capability of the 40A Trustfire. I dont believe it can take the 40 A for a minute! Maybe 20 Amps. About the best storage voltage for Liion batteries - to my opinion its around 3.6 V, not 3.82. It also can be 3.5 ... 3.7 with no big difference in storage behavior. You just should not store them fully loaded to 4.2 V as they suffer the most, when fully loaded. 3.8 V is still 60-70% fully charged, its better to keep the charge lower for longer storage. You should just care about the voltage should not drop below 3.0 volts as this may start to demage the chemistry. The lowest is 2.5V - afterwards there will be permanent damage, but its better to keep 3.0 volts as lowest discharge. It also depends on the actual chemistry - most likely LiMnCo in the 18650.

Nice video. What is the best chipest by 18650 battery?

is there a video on your battery discharger? I'd like to see how its built!!! great video..

Ты русский?

Borat likes.

cOOL acCEnt dUDe. Do you like my new style of writing ?-)

You should trust the trustfire battery

All those battries they are no longer available i checked them on ebay n amozone, pls make a new video with new available battries

why don't you post the websites where you bought these fakes and then also post the websites where you do business buying the real thing

Be careful when they promise 3000mAh or higher. Its already a red flag. Most Branded Lithium Batteries have around 2000mAH to 2800mAh specially those used in Cordless Power Tools. I have opened most of Ryobi, Workzone, Ozito and AEG battery packs and they have these values.

F*ck buying batteries... I'm just gonna go play Super Mario

Another awesome video review of battery’s

Simply outstanding!👍👍👍

What about the claimed protection circuits? Did any of these batteries actually have one?

I had the yellow one and the 9900 one and have never used them and got them on a trade. I threw them away.

Who the Hell buys batteries with 'FIRE' on the label?!?!

Let's unwrrrrrrrrrappedtttttt and fuuuuuuuuuuuuuuuuck it. sorry i couldn't resist.

7:07 I have the exact same multimeter I bought this for almost 9$

Omg 5000mah battery woowe :D damn china.

Informative video..your voice over is serious meme potential.

For fuck sake create amazon affiliate links for the good ones.

Please put caption as it is quite hard to understand what you are saying

Allegro fakes are button top. Hmmm interesting

Dobrá angličtina

I have a brc cell. Its so light hahah like empty can

Is this guy speaking English or what?

Nice video as allways. Please start another channel and show your inventions. I would like to see your dummy load.

fk lol is this guys accent real or is he fkn w us

good video am from india . good saported brother

Could you make video how to make this battery analiser?

Drop the non bionary accent geek

2:50 *RIP Engrish* 😂👌 9:43 cool *dog!*

Your doggo is so cute :3 hehe I love dogs xD

Už tě někdo kritizoval za mluvenou angličtinu? Ne? Prosím udělej s tím něco, videa mas dobrý ale nedá se to poslouchat 😩

ur dog sad

Can't understand a word.

You mean 4.?? grams

I don't trust any fireee lol PS:EARLY SQUAD

Sir, I know English is not your first language, but if you talk a little slower it would help U.S. English speakers can understand you! Other than that, you have some great information. I appreciate that and commend you. I wish we could get sellers like this to be held accountable! Keep up the good work!!!

The 3.82V value you provide for a "new" uncharged battery is problematic. The voltage li-ion cells and batteries should be STORED at is not the standard used for SHIPPING them. New 2018 ICAO/IATA regulations will limit the State of Charge (SOC) to 30% for all lithium ion cells and batteries on both Passenger and Cargo aircraft. Some sources suggest the voltage at 30% SOC is 3.8Volts, but that is not a given. Since li-ion chemistries vary, the voltage at which SOC=30% varies as well. Watt-Hours and "Ampacity" can also be affected by rate of discharge due to heating effects on the chemistry. Any new criterion based ONLY on voltage will require a value published for that specific cell type by a given manufacturer at 30% SOC, or... Alternatively, I could see hobbyists testing a few cells they know they are going to purchase regularly and charge/discharge the test cells as appropriate until a discharge curve can be empirically determined and the voltage at the "30%" SOC point established by the tests. I would suggest starting with using +/- 1 sigma voltage values from such tests, and perhaps increasing to 2 sigma if necessary. It should be noted I've seen multiple devices with the measured cell voltage varying by as much as 0.5V while the device reports SOC=30%. By the way, I think your cell evaluator/charger/discharger would be a useful tool to empirically determine the 30% SOC and the voltage at 30% SOC for a given manufacturer's version of a specific li-ion cell part number.

Very funny ,don't trust fire

2 18650 3000mAh ebay cells arrived here today. One tested at 767mAh and the other at 778mAh. Sad excuses for batteries. Thanks for continuing to test cheap ebay cells.

WTF is this guy saying ????????????

Happy New Year DiodeGoneWild I hate lying companies I never use Aliexpress as I dont trust it What trustworthy reliable manufacturer can anybody recommend please? Love your Dog ❤️

Excellent video. Thank you so much

That accent, what is it?! What's funny is that you detected the misspellings and even pronounced them with the proper level of ridicule, LOL! Sheeflife around 10 years and encironmental friendly, ah!

I go with what I saw in another video- fake batteries will be less than 40 mg. If you don’t have a scale tap together and you can hear by density. Of course common sense says be leery from the higher Rated over 3500mAh for the 18650 size battery

Do 18650 flat top batterys work in devices with 18650 button top. Can you use any of the two types of 18650 in most devices ?

Hello I from Belarus. Let start talk! In russian language, if it's real))) Надеюсь ответите. Let's go!)))

I’M NOT SUUREE ABOOUT IIIIIIIT

I bought some of the ones that clamed the 9800mah and I got them and they were only 800 so I looked back at the link in eBay to find out in the description the 9800mah was the model # not the amount of power so I contacted the seller and eBay and got a full refund and was able to keep the batteries " because there not worth crap " because he was scamming

If i test my 18650 batteries. Should i charge it to 4.2v and discharge to 3v?

your voice very funny dude

This battery is niiiiiiiiiice

Paráda!

Thank god they are ENCIROMENT friendly, I don't wanna kill any acimals
