JUGEE battery teardown full size video.

[@TheOfficialOriginalChad]

I have two of these batteries and have been putting forth great effort to stop myself from taking one apart. Thank you. My remote control will continue to function because of you.

[@Shaun.Stephens]

Are they the same brand? I was wondering how these would go in low drain devices, whether their quiescent current would mean they'd essentially self-discharge under low loads. Then again a remote control is a different device to the indoor - outdoor temperature display that I have (which needs a full 1.5v per cell) in that my device is a constant low drain but a remote is occasional low drain. Hmmm... I have a few of those Znter 9v Li-ion cells and they have high quiescent current so are useless for things like smoke alarms, they go flat within a month or so in a smoke alarm and in 3 months in the drawer. That's why I'd like to know more about these before I spend money that I can't afford to 'lose' as Eneloops do well in most other devices I have. Cheers.

[@darkfur18]

@@Shaun.Stephens That's probably due to the specific circuitry used, and other brands may be better at handling that

[@AndrewGillard]

You often find that higher-current power management ICs in QFN or DFN packages will have their high-current pins (such as the pins to the inductor) doubled- or tripled-up. That might go some way to explaining the oddly-high pin count of this chip.

[@jkobain]

Oh, yeah!

[@generaldisarray]

You have bested me sir, bravo, bravo indeed.... I was just about to say the same thing...

[@groundzero_-lm4md]

Have seen that done before on a 6 pin MOSFET the source and drain were 2 and 3 pins respectively where as the gate is only 1 pin.

[@sincerelyyours7538]

Finally, a rechargeable AA cell that looks actually worth buying. For $30 you get four well made cells and a charger that's smart enough to know good cell from bad as well as right cell from wrong. I remember when it cost about $8 to buy four nicad cells and a crappy charger that had little more than a few resistors inside. Overheated batteries were common and you were lucky to get more than a few charges despite the "up to 500 charges" promised on the package. Thanks for the teardown, Clive.

[@tomschmidt381]

As someone who has been into electronics since vacuum tube days (valves on the other side of the pond) I'm amazed how complex electronics can be squeezed into tiny spaces.

[@davelowets]

Actually, both terms are quite common here in the U.S.... Although it depends on who you're talking to. If you're talking to a Hi-Fi buff, he has "Tube Amps". If you're taking to an experienced guitarist, he has a "Valve Amplifier". Every once in a while, while I'm talking to a Hi-Fi guy I'll refer to them as valves and vice versa with a musician, just to see if I can get them to swap terms, but I've never been successful.. 🤷🏻😁

Traditionally I'm not interested in short videos so forgive me for not watching the short version! And thanks for making this long version!

[@pcrengnr1]

Clive thx for the teardown. That was great and you didn't even cause an explosion. The best part is they don't leak. If anything their failure modes are they explode or quit. On another note thx for the NiMH update that they have majorly improved the self discharge rate. I'm betting these jewels also have a slow self discharge rate even with all that sophisticated converter electronics baked in. You'll have to put a scope between the batteries and the charger to see if they have a conversation. I'm bettin they do. Again, thx clive for the great teardown and no explosion.

[@zybch]

They do seem pretty impressive. Pity they're so expensive, though its easy to see why.

[@chocolate_squiggle]

I got quite excited by the Kentli batteries when I first saw them because of the genius end-cap design, similar to these Jugee ones. A small tip that provides 1.5V with an insulated barrier stepping down to the charging ring for the lithium charger to access. I was thinking they'd provide a longer runtime on my headlamps but I'd been sucked in by their marketing. They advertise as 3000 mWh - which is a better way to advertise battery capacity if everyone did it that way. But they don't, they use mAh and I was confused into thinking I'd get 50% more runtime than my 2000mAh eneloops. Of course they are really only about the same so I gather they're betting on people being confused as I was. Not much point spending mega dollars on them, unless you really do have a device very finicky about the voltage. I decided to just stick with my eneloops.

[@christopherguy1217]

As an alternative you can use Ni-Zn rechargeable batteries, they provide 1.6v and are made for high drain circuits such as cameras and flashlights. I just started using them and I like them so far as a replacement to the alkaline batteries where the Ni-Mh voltage doesn't work.

[@neodonkey]

I was going to mention these, very few people seem to make them, the main brand I have seen is PKCell and they seem very well made.

[@hgbugalou]

I have several of these a few that are over a year old. I have been very pleased by them and have started phasing out my NiMh batteries with them. I have only had 1 go bad out of about 30.

[@fazergazer]

I wondered if immersing the resin in the Jugee into an index of refraction matching fluid might make it “disappear”? Kind of like how mixtures of high index of refraction fluids can make diamond invisible when immersed? Although it looks like it has a glass powder added. 🎉luckily you got the pieces separated🎉

[@alexanderthomas2660]

I bought something similar a few years ago from Kentli. Those have another system for charging, the charging contact is actually right next to the normal positive battery terminal nub. The charger has specially shaped contacts that poke into this slot. One can directly measure the lithium cell voltage through this third contact as well. I guess these Jugee batteries are slightly more advanced and perhaps they also have a higher cell-to-circuitry size ratio, but the Kentlis still do a fine job in a thermal camera.

[@dcallan812]

I picked the longer version just to see Clive destroy the battery.I was not disappointed 👍👍👍👍

[@ChrisBigBad]

Brilliant! Now the question: can I solder one of these suckers into my electric toothbrush? I totally hate the fluctuation in speed I get from my e-brush, being somewhere between "worse than manual" shortly before the low battery warning and "brush go BRRRRRRRRRRR" when fresh off the charger. And I always wondered how to pop in a Li-cell or other voltage stabilized circuit. This might be it.

[@bobb2240]

If the dc/dc converter is running all the time to give 1.5V ,how long is the storage life for a fully charged battery ?

[@nathanboody1148]

Probably pretty good. A good boost converter chip can have quiescent current in the microamps.

[@jkobain]

It must've been reducing its duty cycle significantly once it has topped the output capacitor.

[@Shaun.Stephens]

@@nathanboody1148 This is a buck converter though...

[@joshuaewalker]

I question the 3000mWh rating. It's likely the battery is only capable of 810mAh _NOT_ 2000mAh.

[@threeMetreJim]

@@Shaun.Stephens The same principle holds for a buck converter at no load. It's usually done by pulse skipping; only providing pulses once the output voltage falls. It just sits idle at no load, until the leakage of the output capacitor reduces the voltage far enough.

[@JPennDotCom]

I wonder if there is any detectable ripple at high current draw. Some electronics may not appreciate that.

[@uwezimmermann5427]

there seem to be quite a number of off-shelf buck-regulators in QFN16 for the purpose, e.g. ISL8023, ISL8024, TPS62130RGTT, these are 3-4 A chips...

[@randomsteve4288]

Well you may have the package correct but this chip is more than a mere buck regulator. It is offers a reverse charge path with most probably current limiting and some battery protection. And hopefully also some way of output voltage crowbar. Just imagine the Buck chip shorting out on the switcher path and delivering the full 3-4V lithium battery voltage to the output. And btw; Fujian Nanping Nanfu Battery Co. Ltd presented a cell called NF-LB1 under the Brand Tenavolts in January 2019 which was using this approach already. And they are said to have worked 4 Years on the design and hold 6 Patents on this. On quick search I found www.freepatentsonline.com/20170338521.pdf So I would not wonder if this chip is top secret. But unless it is the same mfc as in 2019, these Jugee may mark the start of a series of knockoffs/ copies of the original design.

[@funksterdotorg]

I found a linear regulator that would be able to make 1.35V from a 1.5V alkaline watch battery, while looking for options for my Dad's old Olympus camera. Great, I thought, and ordered some up. Turns out there had been something of a miscalculation of scale, they are BGAs with 9 pads in a square 1mm to a side. In the end we just 3D printed an adaptor that carries an alkaline cell and a schottky diode, and he has had acceptable results with it.

[@rich1051414]

These use pulse width modulation and the bare minimum filtering(for size constraints), so the output is going to get noisy under even the lightest of loads. That is fine in most cases, but in some cases, batteries are used precisely because of their pristine dc voltage and pulse width modulated voltage will not cut it.

Yeah. Most controllers have a voltage regulator immediately after the battery contacts, and will happily take either a 1S or 2S lipo depending on the design. Be careful though - the battery voltage will likely also feed into a ADC pin on the microcontroller for voltage detection. Some feed directly into this pin, so you may need also to check the data sheet for max input on that pin (it's probably less than the 8.4v of a fully charged 2S pack). Check on forums and such because fairly good chance people have discussed it before unless you use very unusual controllers.

Shouldn’t LiIon have a higher charge density than NiMH? With that 2000mAh at 1.5V it seems to be about the same or lower than the typical high end NiMH cells of around 2700mAh at 1.2V.

[@chrishartley1210]

Found a review video for Jugee batteries from 2 years ago. He didn't get anything like the capacity results you saw and certainly didn't have the constant voltage at higher discharge rates, dropping to 1V at 1.5A. Presumably the technology has advanced in that time.

[@johndododoe1411]

Well Clive only tested up to 1A , Clive's circuit explanation mentions 1V as the output voltage used to alert the load's low battery indicator before complete switch off, so the 1.5A overload might have set this off.

Thanks for finding these Clive, they would be ideal for a number of things around the house, but I've only been able to find supplies from US or Singapore sources. With the high shipping cost, and the Parcel Farce handling fee on top of the GST, I'd be paying more to get them here than the product cost. There are some similar units KENTLI / Hixon but difficult to see if they are of the same quality and they will still attract GST and Parcel Farce charges even though free postage. We are really penalised in the UK by the very low (£15) self import limit for GST.

There is a comment on the Patreon page that this type (but not the JUGEE ones) are available from Amazon UK. I checked and they are: www.amazon.co.uk/YGJ-Rechargeable-lithium-battery-batteries/dp/B07YZCFF1G/ www.amazon.co.uk/EBL-AA-Rechargeable-Batteries-Capacity-Black/dp/B0828GN5RL/

@@Stuart-AJC Must have missed the comment on Patreon . Thanks for those pointers I'd searched Amazon, as well as fleaBay, but they did not turn up, just shows that Amazon search is not perfect!

Are you sure the led's don't show charge level?

I've been waiting for this for so long. I bought a bunch of different brands of the li-ion AA. But couldn't bring myself to tear apart my own set as I do use them heavily.

Finally got around to buying these batteries. There were some of a different brand for sale rated at 3500mAh £24.99) but only described as Lithium, not LiPo. Not being sure of the difference between the chemistries I gave those a miss for the time being and went for the Jugees

Interesting product. These will definitely hold more juice than the ones that have a micro USB charge input at the side. Almost all of its internal space is filled up with battery material. I just wonder how well they do at low-power applications like wireless temperature sending units, remote controls, and so on. Me, I'm done with the self-discharge and the lower output voltage of NiMH, so I switched to LiFePO4: 3.2V at only one cell. The AA LiFePO4 is 1000mAh, the AAA-version is 500mAh.

Idk if it’s a twang when you sproing it with a tool or the sound internally when it shorts, but it makes a buzz sound every time you make a failed attempt

I agree with Astorath The Grim, why would I want to watch a short version and miss out on technical details? No point in watching a "half a job" vid. So anyhoo, my understanding is then, these cells are pretty much good for anything except very high drain applications (old school camera flash or maybe RC toys or power tools)? How long do they hold a charge, are they (for example) suitable for clocks? Looks like a really good product, thanks for the review :)

Haha, You said "probe holes" It was also rather funny, the closed captioning stated that the noise from your Dremel tool was "music" ✌❤😊👽

I was searching for cell like this. Pretty nice design. BUT What about self discharge? This is real problem with this type batteries. AA batteries are used in long time, occasionally turn on, low current items. Quite often its about year or few month. How long it can hold charge to half capacity from full?
