In my favourite top3 You Tubers. (Esp. after looking at his clocks and his cat) - and with so much that made me laugh. DiodeGW is certainly a force among the best of the electronic engineers here on YT. Make no mistake - he has an excellent foundation of knowledge and experience that he shares with great style, quality and humor. Brilliant. I have written a few praising comments recently. I think the effort and time involved and the generosity of the content makers in bringing this new form of media to life, is quite a remarkable thing - thanks to people like DiodeGW. Respect from Martin, a fellow engineer.

The problem with unknown "recycled" cell is that you don't know what happened before. Often they were overdischarged, meaning they've build copper shunt inside the cell leading to internal short circuit and explosion. I discovered this, the hard way. Some of them also don't hold full charge for long and they definitely have much less capacity than before.

The liquid in the battery is the electrolyte. It is needed for the battery to work. It doesn't need to flow out like in the green battery, but the whole system must feel moist. The low performance of the yellow battery is most likely (partly?) due to loss of electrolyte. If you rapidly charge or discharge the battery, it gets hot, which increases the pressure in the cell, and some electrolyte might vent off through the safety pressure release in the positive contact. Also the seal can go bad over time, causing electrolyte to diffuse out even if there is no overpressure in the cell.

The price variance is huge. As such, a cheap, low capacity, but solid cell might be more economical, maybe? Will do some math after taking some samples. I bought a programmable load that will measure a battery's capacity automatically. Thanks.

Actually, En means Energy :). The next screen after voltage measurenemt is energy measurement (energy in watthours). When I long press the mode button to activate the discharge, the meter prepares to show the energy value, but then it realizes that a long press of the button is what happened, and it goes back to voltage display. But En could also mean something like "discharge Enabled", so I left the program this way :).

So the reason why the 1800mAh one was so poor (1100mAh) was because it was specifically made/designed to be low capacity, there was not enough material inside to be of decent quality or capacity. The inside was hollow... And the reason why the 2400mAh battery performed so badly was because it was a recycled cell, probably from e-waste, where they take the battery pack, disassemble it for the 18650s, and then they just re-wrap it, shove new contacts on, and sell it to you. Under those circumstances it really is pot luck as to what capacity you will get (the previous UltraFire recycled cell was 1500mAh).

Práve rozoberám baterky z HP notebookov a už mám vyše 100 článkov Samsung ICR 18650-28A. Kapacita je od 2000 do 2500 mAh, podľa kusu. Väčšina je okolo 2350 mAh Zaujímavé je, že tieto články sú stavané na nabíjacie napätie 4,3 V, ale ja ich testujem iba v rozsahu 4,2 - 2,8, takže ani nevyužijem max. potenciál týchto článkov. V praxi ich chcem nabíjať do 4,2 V a vybíjať do 3,0 V. To by mi mohlo dať kapacitu okolo 2300 mAh. Dúfam... Uvažujem spraviť si 10S10P battery pack pre bicykel. Maximálny trvalý odber by bol 7 A, takže 700 mAh na článok, čo zvládajú bez prehrievania (vyskúšané).

Áno máš pravdu. Vyberám však iba články jednotného typu a podobnom počte cyklov a podobnej kapacite. Mám ich dosť, takže je z čoho vyberať. Problém je v tom, že pri prvých článkoch ktoré som vyberal som si neskontroloval počet cyklov ani vek baterky... Ale zo skúsenosti vidím, že počet cyklov je priamo úmerný kapacite, takže to hádam nebude až taký problém. Rôzne vnútorné odpory budú znamenať nerovnomerné vybíjanie a nabíjanie. Som zmierený s tým, že mi baterka bude degradovať rýchlejšie než by sa očakávalo. Baterku si vyrobím 7P10S, aby nebola zbytočne ťažká. Využívam 3D tlačiareň na moduly N.E.S.E. Sú rozoberateľné a každý článok bude vymeniteľný samostatne. Ak uvidím že jeden z desiatich modulov stráca napätie rýchlejšie, môžem ho otvoriť a skontrolovať jednotlivé články, nájsť problémový a ten vymeniť. Celá batéria je bez zvárania alebo letovania, čo je super konštrukcia.

You missed to measure the length and the surface of this piecees of 'copperpaper'. Also their individuell weights would have been interesting. Maybe you should consider to repeat this test in some future. Maybe we find out even more and new things today. And they say, that lots of different prescious metalls are in this copperblend. Maybe it's as well possible to measure and calculate the specific weight. We know the surface, so we only have to measure the thickness as well properly. Maybe it would be of some interest anyway to know the thickness of all such samples, they may not all be the same?

The chemicals in a Li ion battery are quite harmless. The liquid is an organic solvent (about as dangerous as acetone and the thing that actually burns - the lithium is irrelevant for li ion battery fires). Dissolved in it are Li salts, can be acidic in certain circumstances, but is not really an issue. The only danger is fire, because it burns your house down. Also you can get HF in a fire, because one of the often used lithium salts also contains fluorine. So have plenty of water ready and you are fine.

Dear Sir I hope a can call on your expertise! I have a Boston Acoustics Subwoofer ASW 650 with a faulty power supply. The service manual shows a transformer based power supply, but the one with the unit is a switch mode power supply! Does anybody have a circuit diagram for the Smps? Thank you in advance. Kind regards

Yeah, but you can buy batteries from trusted websites (or even better, official). Then can have bigger price, but you get what you pay for.

Well, just buy from a well known source like farnell, digikey or alike. You can also trust Amazon - if Amazon is the seller and you buy high priced stuff from Samsung, Sony, LG Chem or Panasonic. A good 2400 mAh costs around $6-7 or 6-7€ + VAT, a good 3000+ one around 9-10€. If they are cheaper, they are trash.

@@hermannschaefer4777 you can consider high price also a primary reason why I do not get involved. Although $6 a cell isn't too bad. I need quite a few for what I want to do though so any reduction of individual cell prices would add up. Every pack I want needs 5 cells in it. Ultimately I would not mind having 5 or 6 packs. So 25 or 30 cells.

You'll get absolutely nowhere if you are *_that_* risk averse. You are basically admitting that you do not even trust your own intelligence. Well, I trust my own intelligence and I buy lots of 18650 from the internet. It's all about educating yourself. There are practically tons of KZbin videos out there dedicated to spotting and identifying fake and recycled batteries. It really is your loss.

Hi I recently purchased a 18650 2500 mah battery I charged them with my newi2 nitecore charger and used it In my vape but before u can use it I can see 20% battery has already been drained and plus it heats my vape mod I use armour Pro mod. Is it normal for a new batteries to act like this or are they clone batteries.

The spot welding marks are probably not that easy to hide. They could sand a hole through it :). Sanding would also make a noticeable pattern. Putting a piece of metal over it is probably faster and more simple. They always do things the fastest, simplest and cheapest way ;).

The moral of this video, is don't buy cheap bargain basement batteries, you'll pay for it twice due to their lack of power/defect, or worse yet they leak or puff up and burns your equipment. Also, only buy from well known reputable sellers. By the way, AliExpress, BangGood, etc are NOT sellers themselves (they are just online portals for sellers) so you must search for good seller on those websites, or better yet use Ebay or Amazon. ;D
