+Andrew Cleon In video, the guy made a point to hold the monkey a specific way when testing with the batteries. When Dave held it that way, the drain on the batteries increased. So, clearly, some research was done with their demonstration to make the optimal conditions to for showcasing their claims. AKA, stacking the deck
The best test you could do is to test their actual claims. Stick some fresh batteries in a device, let's say an mp3 player, measure how long it plays for until it's dead and then stick the batteriser sleeve on the batteries and measure again. They claim they you should get up to 8x the play time using the sleeve. I doubt you will even get 8 minutes.
Batterizer are obviously monitoring Dave's channel closely because Dave never gets this many thumbs down. And yet all of the comments here support Dave's argument (and science also supports Dave's argument). A few years ago you could buy subscribers and votes, and you probably still can. It makes me wonder if Batterizer are buying thumbs down votes! Either that or they're getting all of their investors, friends and family involved.
+Mya Mi ....the "Batteriser Batteroo" channel has a grand total of 9 videos, and they are all substandard infomercials. i strongly recommend checking them out!
Honestly, merit aside, hammering the same points over and over for 26 minutes in his squeaky whining voice is getting on my nerves. This really could have been a short follow-up of 5 minutes or so and it could still contain all the points made. The points raised are valid but the delivery is just awful.
+EEVblog You there! Just read the MCP1623 datasheet, the Keithley 2302 datasheet, and the bq20z80 datasheet, and you will realize the error you're making in this video, and what you should be mentioning. Read "9_27_07_PerformanceMetrics2" from Berkeley for how 'ionic diffusion' works as well.
+Saxie81 Okay, I will try to explain what EEVblog is stating incorrectly precisely here: In the MCP1623 datasheet, revision C, document code 41420C, page 12, subsection 4.2.6, it will state that the device operation limit is given by the output power relative to the input source series resistance. This is due to the fundamental properties of P=IV and V=IR. On page 11, subsection 4.2.1, paragraph 5, it will state one of the issues this may cause on batteries which cannot source the appropriate current at a particular voltage, which may be in contrast to PSUs. In the entire datasheet for the Keithley 2302 hardware battery simulator, it will indicate the time and surge differentials for devices, like transmitters, which may have different operating modes, and thus change their current draw on the battery: The device may function fine at one energy level, but cut out when asked to switch modes. Finally, a terminal comparator is not the only way a device may detect it has low power: The bq20z80 is a power management IC that uses 'coulomb counting', measuring the charge from the battery as a product of current, and additionally it measures the 'internal resistance' of the battery to determine the battery's 'health', and thus in part 'maximal charge level'. If you just plug a bare PSU into a device using a method like that, it will give a fundamentally inaccurate reading. EEVblog has to be mentioning what different devices are actually DOING. Just using a bare PSU and calling it 'good' is fundamentally incorrect.
You can't make yourself clearer than that! I worked for many years with batteries (robots, and energy harvesting). And determining the amount of energy left in a battery is an approximate science (which models and Coulomb counters have helped to get more accurate, but it will never be exact). Thanks for that crystal clear video!
Is the economy so bad that people can't afford batteries? This Batteriser product seems to play into the common misconception that you can get something from nothing, aka, a free lunch.
I first saw the effects of how batteries work as a 5 year old, had a flashlight, it went flat.. Turned it off for a minute BAM started working again! well for like 30 seconds!
FCC handles wireless spectrum and RFI interference issues almost exclusively. Now, if the product should turn out to emit excessive RFI as an unintentional radio emitter then the FCC may well get involved if enough complaints are received. If it flops as a product, investors may be able to file claims against Batteroo by way of the SEC or via class action litigation. If it catches fire or harms people then the CPSC (product safety) becomes a recall avenue. The closest to what you were intending would be the FTC (federal trade commission) which does handle "truth in advertising" cases, but it can take quite a lot of complaints and the fact that the device will at least partially deliver on claims in select special use cases can really complicate matters since it can not be proven to be 100% fraudulent. If the product is appropriately defective in engineering the FCC and CPSC are the best hope for aggressive action *if* it comes under their jurisdiction after the fact.
+Ethan Poole Indeed, the FTC is the one to go to here. Notably however, if they're making an "up to 800 percent" claim, and don't actually have a verified commercial product test where that specific number is true, the FTC might smite them immediately. I.E. stating technicalities will still invite litigation if they are misleading, like saying "this food product cures cancer" by way of the technicality that eating is likely an essential part of restoring a person to health.
+Gravity You are much more optimistic than I, but we can at least dream. There does need to be more consumer and investor protection from such business and marketing practices So many of our regulatory agencies have had their budgets and personnel cut back so much over the past thirty years that many of them have fallen hopelessly behind on enforcement actions as it takes both man hours and money to pursue enforcement actions...there is a reason why so much dangerous and non-compliant merchandise finds its way onto retailer's shelves than there used to be (defective Asian products only enter this country when we allow/ignore them). Businesses and individuals alike use to fear an FCC compliance visit - nowadays they almost never happen except in the most extraordinary cases. It is practically a running joke. In fact, the FCC is shutting down most of their offices, and many personnel, to meet current budget constraints even as the breadth of their responsibilities grows.
+Ethan Poole Well the FCC is a bit different, especially since a lot of modern technology is EMI resistant, and honestly people are better at complying with those regulations. It's much easier to tape down an EMI violation source these days as well. The FTC and SEC are actually pretty bulldog-aggressive if they have a clear case. The FDA even moreso. They don't want to be too harsh, because some odd claims can actually turn out true. But if they have a clear cut 'this is bullshit' case, they'll almost certainly rip the money out of that company. The original anti-'snake oil' lawsuits I believe were from the government. Con-artists damage the economy, making less money for the population and the government. So organizations like the FTC may tend to be pretty well on their game.
I love the clip of Julius Sumner Miller you put in there, I haven't thought about his shows in ages... His experiments and demonstrations really cemented the lessons in your mind, his manner of investigation was infectious.
If there's one thing about this that's misleading, it's the approval rating of this video. 500 dislikes in 12 hours, and then no dislikes at all. I think someone's playing it dirty.
+Ernst Stavro Blofeld Well, won't the Batteriser, by its nature, tend to constantly drain current from the battery? More than what the product by itself would (due to efficiency being
Charlie Pechiar No since the Batteriser uses chips, which have a (very low) cutoff voltage themselves, an almost infinite drain, like in Dave's Indiana Jones experiment, will be prevented.
+Ernst Stavro Blofeld No, he got it right. Fully discharging batteries can make them leak. It also damages recharegables and makes them lose capacity. Your batterizer will do both of those things. Enjoy it!
+Ernst Stavro Blofeld Rubbish. The Batteriser has to work in every type of device, including devices with microamp surrent drains like remote controls, Apple keyboards, etc. Microamp loads will mean the battery voltage under load is almost the same as the open-terminal voltage. Even a dead battery has an open-terminal voltage of about 1.2 Volts, as clearly shown in this video. When does the batteriser shut down? At 1.2V? That's still a full charge in a high-drain device.
It would also be bad idea to use the Batteriser in a product that shows a "low Battery" warning since this circuitry only measures voltage and not current. The Batteriser always boosts the voltage up to 1.5V that circuitry would not detect a "low battery" and never show the warning. It would just continue operating until the current gets too low to actually operate it. This would be critical for Remote controlled vehicles or devices that use a battery as a backup to store data.
Comment from a person who actually owns a Batteriser (please read whole comment before trolling...) All the videos Dave did about this thing made me so interested that I actually, just to try it out, bought two batterisers. They were 2€, and I was curious, so... What I could find out: 1) They actually work. Many people think that it's just a metal bracket, but they do what they are supposed to do. 2) They (mine) do work down to 0.55V. That's pretty cool for a boost converter, and yes it is a normal boost converter we all have seen at some point in our life, though it's an impressingly small one. 3) Under 0,8V, there is not a huge load of energy left in a battery (if any at all), so 800% is pretty optimistic. It is even very VERY HIGHLY optimistic..... Actually, I didn't notice any change at all in runtime. 4) Anyways, I found an actual use for these things (believe it or not!) and it is as obvious as boring. I have them in my old MagLite with the oldfashioned incandescent halogen bulbs. The one thing that really annoyed me about that flashlight is that when the voltage drops it gets dimmer. The batteriser does, surprisingly enough, effectively prevent on that. But, till now, that's about the only use I found for it, and because I also own a way more efficient LED flashlight... 5) I am still waiting for ElectroBOOM trying to electrocute himself with 100 batterisers with depleted batteries.
Thoroughly busted! I love your channel mate! I've just discovered the channel a few days ago and already watched several videos and learned a lot. Thanks for making great content!
I suppose part of the problem could be that the general public has been trained to test their batteries in open-circuit, back when all the manufacturers had those little testing strips on the sides of their batteries.
Has anyone confirmed that the guy in the video is a professor? As I am pretty sure that the facility department head would have more than a few strong words with him.
+Matthew Wagg you may well be right Matthew if he was genuine you would think they would include his name as someone who endorses the validity their product.
+andrew mcneil The batterizer folk are complete and utter noobs. In their "Comparing Constant Power Supply with Batteries" video the guy says "This monkey uses to batteries in series" to try and sound all professional to the punters hoping that they're easily fooled. SHOW ME A MONKEY WITH TWO AA OR AAA BATTERIES IN PARALLEL...LOLZ!!
I can see the batteriser reply to this already. "so he discharged a battery to 0.8 volt, then claims this is the same as a battery with 1.2V 'energy' left.
Dave, have you seen Batteriser's latest video? It seems to be a response to your previous video. Their point seems to be that the fluctuations in voltage due to the irregular demand for power of some products can trigger the batteries to momentarily drop below the cut-off voltage and stop working.
+EEVBlog Thanks so much for this. I don't think these videos are excessive at all. I learned a lot. I am by no means any more than a spectator when it comes to electronics, but I have been watching you for a loooong time. I have never even soldered a decent joint and I knew why that test was flawed just from watching your other battery videos in the past. You absolutely do make a difference and I hope you remember comments like this on the days you just don't feel like making videos :)
Note that this is similar to checking a dead car battery. if there's no load on the battery, it'll still read around 12 volts. However, turn the key and "tick"... nothing!
Always enjoy watching your debunking videos! Even though you don't skimp on the technical details, you put the facts across clearly without using fancy sounding jargon to confuse the viewer. Keep up the great work!
Do many other folks still use many alkaline batteries? I'm searching around the house and I can find only a few products. The only ones that truly concern me if they die are smoke alarms and my mouse.
can you comment on their last video about current surges and the 80% claim? I just watched 20min of the guy asking the engineer what the average value of every single thing was for no reason.
+Prastt The 80% claim is pure bullshit. It simply isn't true. It's based on a dumpster-dive study that shows that some people throw perfectly good batteries away when (e.g.) they go away for a weekend and want to be sure they have brand new batteries in their camera (or whatever). This doesn't mean their camera couldn't use up the battery, it means they deliberately threw them away. That's an important difference, but it's what Batteriser is basing their claims on (batteriser is basically saying that *all* the batteries in dumpsters are thrown away because the owners thought they were dead) Current surges? Does your phone keep shutting down suddenly when you touch the screen or turn it on? Nope, because real devices have things called capacitors in them to smooth out the bumps. It's electronics 101.
You can sometimes tell a flat-dead cell from a half-dead one by checking with multimeter: if the truly open-voltage measures the same (down to milivolts) as when hand-loaded (sweaty fingeurs across the battery poles while holding the probes)
Forget it, Batteriser already dropped that argument. Now all of a sudden the main argument are the current peaks which the batteriser compensates for...
Dear Dave! You both have right with Batteriser :) Batteries are different from power supplies :) Battery voltage will drop after you apply a load (even a load for which a battery is designed). On the other hand, good power supply, while loaded with designed load should not change it's output voltage. While designing battery operating circuit you should assume, that battery voltage will vary as hell, while circuit designed for a power supply, may expect constant and stable voltage. In a company I worked for, we assumed that battery voltage may vary from 0,7 to 1,6 V per AA alkaline cell. And yes, we used boost-converters to extend battery operating time :) Alkaline cells have much lesser internal resistance (even if discharged) than carbon-zinc cell, so in case of alkalines boost converter may help.
Gavin Crouch Batteriser Batteroo commented on the "800% Baloney" video on TH-cam. Shared publicly - Aug 9, 2015 "Hi Dave and EEV Blog. Let's vote to have Dave take time out of his busy schedule and review the Batteriser! I hope this video is enough to make you believe that this product is not a scam: th-cam.com/video/d485JCtGz5c/w-d-xo.html Contact me, if you are interested, we would love for your review (or rant if you don't end up liking it). Batteriser@gmail.com"
+Kakunapod This is not snake oil, their product is just a boost converter and it works, but their claims are misleading, it's a scam, I just want to see them go up in flames, they even had the nerve to try and prove Dave wrong, but as we see here they got destroyed one more time.
Gordon Freeman I think youre being a little generous. Their claims are not misleading, they are wrong. Some of them are just misleading, but theyve made plenty of wrong ones as well.
Kakunapod They wouldn't be in this mess if they were honest about their product and just said it as just a boost converter, the "up to 8 times more battery life" is bullshit and they know it.
Can you make a response to the new batteriser video that came out 6 days ago which explained the batteriser in more depth. I would like to see your comments on it.
+pa0070707 I am just looking at that video and at 9 minutes into the video the CEO shows that he does not know the difference between voltage, current, power and energy - even worse, he claims that the critics don't understand these terms...
+pa0070707 this appears to be the paper the CEO is citing. Interestingly he claims around 14:00 that he himself has come up with a spice model of the battery... www.ni-cd.net/accusphp/forum/docjoints/ID2051_Modelisation_decharge_batteries_Pspice.pdf
+Uwe Zimmermann Isn't PSpice a bad way of getting solid results? I was told during my engineering course that it's good for rough work but it doesn't take into account other variables that could influence the outcome.
+pa0070707 This is a slap fest. Both them and EEVblog are wrong. It's absolutely true that using an uncompensated PSU is an incorrect way to test device cutout, that's why professional hardware battery simulators exist. It's also perhaps incorrect to state the dc-dc converter product would overcome ionic diffusion losses of capacity, since it must inherently draw more current to boost the voltage for a set power, as per P=IV. The energy left in a battery is as well of course an integration of the voltage supplied at the current drawn, so him coloring in those alternate parts of the graph is definitely disingenuous. And finally, neither of them are mentioning or using a coulomb counter, one of the actual ways to precisely measure how much charge is entering or leaving a battery.
Dave's video is direct to the point with fully functional equipment that was a true method and from my observation as an EE, I totally agree with Dave. The sad part about the Crapperiser is that it's one of many snake oil companies that Silicon Valley is being flooded with and even experienced investors are falling for crap like it. What I really thought was laughable about that Crapperiser video was all of that fancy video production, yet a desk full of non-functional items along with an invalid method performed by an imposter.
DURALOCK means that battery won't discharge itself when it, for example lays on the shelf for quite some time, it DON'T mean that it won't leak if it's discharged to 0..
I find you coarse, vulgar, exceedingly energetic....and massively entertaining (the accent helps a bunch). My hat (if I actually was wearing one) is off to you, sir. Like Big Clive and Julian Ilett, I've learned more in a week of watching your videos than I ever did at ITT Tech.
That is because they are Alkaline right? Which maintains high voltage as the energy is drained, unlike "heavy duty" and "super heavy duty" batteries which their voltage drops as the amps get used up.
You should take a look at Duracell's own built in "Powercheck", It works by loading the battery and heating a liquid crystal type temperature strip to show remaining capacity, I think they know what their doing.
A good talk that I am curious with is why do batteries leak when they reach zero energy? Is one of the terminals start to eat out of the battery? Also, is this why we see some batteries we leave in a device for years and come back and see corrosion?
+Kairotan Some gas is usually generated in the battery from electrolysis, which can rupture the seal. Corrosion from outside or inside sources may also occur. Wikipedia should have a section on it under "alkaline batteries", with failure modes for different chemistries potentially being different.
There is another 85 years to go in this century. I have unshakeable faith in my fellow man to top the Batterizer at least a few times during the remainder of this century -- probably with dubious technologies we have not begun to think of just yet. In the first half of the prior century radium tainted water was sold as a health elixir to improve sexual prowess...and continued to be sold until some fool consumed more than a thousand bottles and lost his lower jaw in the process (the very definition of ”sexy”). Now who would have thought of selling, much less ingesting, radium as a health elixir? My fellow man...ain't we genius?
one final test, 2 identical led flashlights side by side same batteries except one has batteriser. Time lapse till drained. I know it doesn't work, but would make for a good test.
the only thing I think this batteriserr may be useful for is perhaps an led torch or very badly designed product that has a cut off voltage set too high. surely if using it in say an led torch you would be trading operating time for brightness ?
+TRDreams Ummm.... exactly the opposite. Any decent LED torch will already have a boost converter built-in. That's why they stay bright and die suddenly.
mines a £30 handheld lamp so should be decent one of those ones they use in garages, it certainly fades out slowly over time. Might have to pull it apart to see if there is indeed a converter! I'll also find the model of it
Is it safe to assume that all battery types (lith-ion, lead acid, nicad, nimh, etc) exhibit this behavior of floating up to a higher voltage when not under load?
Depending on the size, they should instead market the product to people who may have a number of flashlights which do not have regulated outputs, or make retrofit devices for use with flashlights with unregulated supplies. That should at least keep the light brighter for the duration of the battery life.
Of course the folks at Batteriser know these things, they are just counting on their customers *not* knowing or being able to prove it. Thanks for the clip of Julius!
Simple: By the time the battery reaches the cut off voltage for the product it's powering, there is practically no energy left in the batteries since most products have such a low cut off voltage. Nothing more needs to ever be said.
What _is_ misleading is taking the manufacturer's discharge curve and assuming it's showing the battery's open-circuit voltage, when in fact it's showing the battery's voltage when under load. And that's exactly what the batteriser people are doing. What I have learned from these videos is that a battery's open circuit voltage is pretty random and tells very little about how much charge is left in it (which is the crucial part). You could have an almost empty battery showing 1.2V when measured open-circuit, but that really tells nothing. It won't run a device at 1.2V, but something a lot lower.
Batterizer hired an online company to thumb down all his videos on the batterizer/bateroo. He has a video showing something to the tune of 500 dislikes coming from vietnam on the same day on all his batterizer videos.
Looks like Batterizer has been paying for more dislikes... not nice Batterizer. Thanks Dave. This is why when I check my batteries, anything less than 1.3V open circuit (just for stupid VERY rough estimate) usually heads for the flashlight bin. Flashlights work great with such low energy. Another great video Dave.
Hey Dave, I stumbled onto your channel a few days ago, and just wanted to say that I appreciate you going into such depth debunking this batteriser product. I'm a trained computer engineer, but have never really spent much time studying batteries, so when I heard about the batteriser, and read through their marketing materials, I thought, "Wow, that kinda makes sense that it can use the extra voltage energy that is left after the device cuts out at 1.3 volts, etc." Your previous two videos went above and beyond in proving that the cutout voltage for most devices is nowhere near that high, making any gains from the batteriser negligible. The fact that they're making these strawman argument video replies is hilarious. Keep up the good work, mate!
Will the batteriser fool a smoke detector. I would love to use rechargables in the smoke detector. When I put 2 NIHM AA batteries in, within 15min the detector starts saying "Low Battery".
+Yik Wai Donald Leung you can not order it "directly from stock" as of now. You would have to use kickstarter. As usual with kickstarter: Who knows when they ship it? I mean: As always stuff can get delayed for a good reason. But... Donating 40$ to them in the hope that they can deliver, just to prove them wrong... THEY are making the claims for an unreleased product - they have the burden of prove.
I find it funny in that the last video that Batteriser uploaded, they suddenly are (partially) using a Rigol DS1054Z and have a Hakko FX-888D sitting on the bench. Very similar to what Dave has sitting on his bench...
Would it be possible to to maximize battery energy extraction by using some king of pulse drain scheme with a storage capacitor to provide a smooth voltage to the end device? I think it is done with small lithium batteries but could it be helpful with alkaline batteries?
Why don't they market the Batteriser to be used with "dead" batteries in remote controls, calculators and so on? It seems it would actually somewhat work in such applications and that would also be honest... Now they are only losing cred for lying... Or?
+Maria Engström a) Because most low power products like that already do a pretty good job at working at low voltages. And b) You won't get that much extra life from them in the scheme of things.
You should have some mythbusters-like signs made out of PCBs... "BUSTED", "PLAUSIBLE", "CONFIRMED" but I assume you'd only ever bother with one that ends up in the first category....
Exactly. It's like saying "My car old dead battery is alright, it reads 12v" then you wonder why the bulb or starter motor you just tried running off of it acted as if it was in open circuit and the voltage reads under a volt closed circuit :P
Just tried testing my Metrix MX54 multimeter 9V battery. The TESCO VALUE battery is at 8.5V open circuit, turn on the meter and it drops to 7.8, fire up the back light and it drops to 4.1V. Also the screen dims and the low battery waning activates. The TESCO Extra Long Life battery is at 7.5V open circuit, turn on the meter and it drops to 7.3V, fire up the back light and it drops to 6V and continues dropping. In conclusion this not only backs up what Dave says but also demonstrates that the TESCO Extra Long Life battery is still useful despite having a lower open terminal voltage making open terminal meserment useless for even getting a rough idea if the battery is still good. The multimeter used for testing the voltage of the battery's was a Thurlby 1905a in 6 1/2 digit mode. If I had gone on open terminal mesherment I would have chucked the wrong battery. Even with out the Bateriser debunks these videos have been very interesting and informative. The Bateriser just makes the video even funnier and makes it more entertaining. Thanks Dave, once again you have helped improve my electronics knowledge.
Batterizer probably used carbon zinc cells in their video, its trivial to get them to recover to like 1.25 but then drop the moment you sneeze a bit of current on them. Much higher internal resistance.
You know how Duracell have a handy Powercheck feature? I have not found a rechargeable with the feature is it because the rechargeable stays at 1.2v for a while? Is the powercheck accurate? I guess it puts the battery under load?
+Knuckles the Echidna Yep, it loads the battery with a heating resistor and you see the strip change color, if heated enough. Rechargeables hold almost constant voltage to the very end, so you could only detect, that it is dead if you put a Powercheck strip on it.
I have not seen one of those Duracell powercheck strips in ages now that you mention them...I had almost forgotten about them despite regularly buying both Duracell and Energizer brand batteries for decades. I did not know they still existed. But as bumv2 states, the powercheck was simply a long film resistor with temperature sensitive liquid crystals (like those thin strip thermometers used on aquariums and such). The heat generated both provides a proper test load and warms the temperature sensitive liquid crystals creating a simple bargraph effect. A clever ultra-low cost battery tester.
"...because the batteries don't measure 1.25v per cell when you stick them back up the monkey's butt." This whole debate notwithstanding, that's pretty much the first time I've ever heard THAT mentioned on a TH-cam video...or anywhere, really. LMAO.
Even in my electronics kit I got at the age of about 12, they explained that the voltage under load is different from the voltage without load. Well, as usual: If a claim is too good to be true, it probably is bollocks!
I would love to see Batteriser produce another video trying to show this video as wrong. Not possible, I believe you have won this battle. Also some great information on why batteries can recover voltage like they do. Its a very interesting topic seeing how more and more products are battery powered. I would like to see more videos on designing battery powered products, rechargeable products, and how the recovering voltage of batteries effects your product design. Thanks again for all your videos, and good "trusted" information
In the Batteriser video the monkey never stopped working! Just the toy did.. Get your facts right dave!
+Andrew Cleon Haha excellent correction.
This is an insult to monkeys, as monkeys don't lie and actually obey thermal dynamics and quantum mechanics.
+Andrew Cleon In video, the guy made a point to hold the monkey a specific way when testing with the batteries. When Dave held it that way, the drain on the batteries increased.
So, clearly, some research was done with their demonstration to make the optimal conditions to for showcasing their claims. AKA, stacking the deck
+Andrew Cleon
Andrew Cleon - for a second, I thought you were trying to defend the batterizer. I see what you did though😏👉
"Just a quick follow-up video"
26 minutes long. Not that I'm complaining.
Someone at Batteriser probably thought this thing was going to make easy money, then Dave showed up, lol.
The best test you could do is to test their actual claims. Stick some fresh batteries in a device, let's say an mp3 player, measure how long it plays for until it's dead and then stick the batteriser sleeve on the batteries and measure again. They claim they you should get up to 8x the play time using the sleeve. I doubt you will even get 8 minutes.
Batterizer are obviously monitoring Dave's channel closely because Dave never gets this many thumbs down. And yet all of the comments here support Dave's argument (and science also supports Dave's argument).
A few years ago you could buy subscribers and votes, and you probably still can. It makes me wonder if Batterizer are buying thumbs down votes! Either that or they're getting all of their investors, friends and family involved.
+ForViewingOnly there is definitely a batterizer troll army going after dave. i might have to make my way to their channel to see wasup...
+Mya Mi ....the "Batteriser Batteroo" channel has a grand total of 9 videos, and they are all substandard infomercials. i strongly recommend checking them out!
+Mya Mi Are you talking about the "fan" page that's not in any way associated with them? lol what a joke these guys are....
+hardstyle905 Fun Fact #2 - my original comment above was posted 2 or 3 days before that video of Dave's that you linked to.
Honestly, merit aside, hammering the same points over and over for 26 minutes in his squeaky whining voice is getting on my nerves. This really could have been a short follow-up of 5 minutes or so and it could still contain all the points made. The points raised are valid but the delivery is just awful.
Your video does not count comparing to theirs. There is no soothing music behind your voice, so it is not convincing at all.
+yoksel99 The data speaks for itself.
+EEVblog ah, yes, but you forget their argument's bottom line - they want money, so laws of physics dont count.
+EEVblog You there! Just read the MCP1623 datasheet, the Keithley 2302 datasheet, and the bq20z80 datasheet, and you will realize the error you're making in this video, and what you should be mentioning.
Read "9_27_07_PerformanceMetrics2" from Berkeley for how 'ionic diffusion' works as well.
+Gravity I fail to see the error
+Saxie81 Okay, I will try to explain what EEVblog is stating incorrectly precisely here: In the MCP1623 datasheet, revision C, document code 41420C, page 12, subsection 4.2.6, it will state that the device operation limit is given by the output power relative to the input source series resistance. This is due to the fundamental properties of P=IV and V=IR. On page 11, subsection 4.2.1, paragraph 5, it will state one of the issues this may cause on batteries which cannot source the appropriate current at a particular voltage, which may be in contrast to PSUs.
In the entire datasheet for the Keithley 2302 hardware battery simulator, it will indicate the time and surge differentials for devices, like transmitters, which may have different operating modes, and thus change their current draw on the battery: The device may function fine at one energy level, but cut out when asked to switch modes.
Finally, a terminal comparator is not the only way a device may detect it has low power: The bq20z80 is a power management IC that uses 'coulomb counting', measuring the charge from the battery as a product of current, and additionally it measures the 'internal resistance' of the battery to determine the battery's 'health', and thus in part 'maximal charge level'. If you just plug a bare PSU into a device using a method like that, it will give a fundamentally inaccurate reading.
EEVblog has to be mentioning what different devices are actually DOING. Just using a bare PSU and calling it 'good' is fundamentally incorrect.
You can't make yourself clearer than that!
I worked for many years with batteries (robots, and energy harvesting). And determining the amount of energy left in a battery is an approximate science (which models and Coulomb counters have helped to get more accurate, but it will never be exact).
Thanks for that crystal clear video!
Is the economy so bad that people can't afford batteries? This Batteriser product seems to play into the common misconception that you can get something from nothing, aka, a free lunch.
I have learned so much from you today. You are a fantastic presenter and teacher. No matter what never stop doing what you do!
And now a moment of silence for probes' battery hole, he really took one for the team.
I first saw the effects of how batteries work as a 5 year old, had a flashlight, it went flat.. Turned it off for a minute BAM started working again! well for like 30 seconds!
They are probably gonna end up saying their instruments were off
+Moondeck I guess the brain is an instrument...
yep
+Moondeck
Don't ananalyse - Batterise!
Moondeck
It's a good business. I just sold more than 100 000 Batterisers over ebay to EEVblog viewers. who all want to debunk it, hehe.
not sure if troll or 4real XD
Can't some of the US folks here file a FCC complaint about misleading advertising and fraudulent claims?
FCC handles wireless spectrum and RFI interference issues almost exclusively. Now, if the product should turn out to emit excessive RFI as an unintentional radio emitter then the FCC may well get involved if enough complaints are received.
If it flops as a product, investors may be able to file claims against Batteroo by way of the SEC or via class action litigation. If it catches fire or harms people then the CPSC (product safety) becomes a recall avenue. The closest to what you were intending would be the FTC (federal trade commission) which does handle "truth in advertising" cases, but it can take quite a lot of complaints and the fact that the device will at least partially deliver on claims in select special use cases can really complicate matters since it can not be proven to be 100% fraudulent.
If the product is appropriately defective in engineering the FCC and CPSC are the best hope for aggressive action *if* it comes under their jurisdiction after the fact.
+Ethan Poole Indeed, the FTC is the one to go to here. Notably however, if they're making an "up to 800 percent" claim, and don't actually have a verified commercial product test where that specific number is true, the FTC might smite them immediately. I.E. stating technicalities will still invite litigation if they are misleading, like saying "this food product cures cancer" by way of the technicality that eating is likely an essential part of restoring a person to health.
+Gravity You are much more optimistic than I, but we can at least dream. There does need to be more consumer and investor protection from such business and marketing practices
So many of our regulatory agencies have had their budgets and personnel cut back so much over the past thirty years that many of them have fallen hopelessly behind on enforcement actions as it takes both man hours and money to pursue enforcement actions...there is a reason why so much dangerous and non-compliant merchandise finds its way onto retailer's shelves than there used to be (defective Asian products only enter this country when we allow/ignore them). Businesses and individuals alike use to fear an FCC compliance visit - nowadays they almost never happen except in the most extraordinary cases. It is practically a running joke. In fact, the FCC is shutting down most of their offices, and many personnel, to meet current budget constraints even as the breadth of their responsibilities grows.
+Ethan Poole Well the FCC is a bit different, especially since a lot of modern technology is EMI resistant, and honestly people are better at complying with those regulations. It's much easier to tape down an EMI violation source these days as well.
The FTC and SEC are actually pretty bulldog-aggressive if they have a clear case. The FDA even moreso. They don't want to be too harsh, because some odd claims can actually turn out true. But if they have a clear cut 'this is bullshit' case, they'll almost certainly rip the money out of that company. The original anti-'snake oil' lawsuits I believe were from the government.
Con-artists damage the economy, making less money for the population and the government. So organizations like the FTC may tend to be pretty well on their game.
+Ethan Poole I think TINA.org attempts to fill those cracks?
I love the clip of Julius Sumner Miller you put in there, I haven't thought about his shows in ages...
His experiments and demonstrations really cemented the lessons in your mind, his manner of investigation was infectious.
If there's one thing about this that's misleading, it's the approval rating of this video. 500 dislikes in 12 hours, and then no dislikes at all. I think someone's playing it dirty.
So, with the Batteriser the batteries are more prone to leak? Another downside?
+Charlie Pechiar No you got that wrong.
+Ernst Stavro Blofeld Well, won't the Batteriser, by its nature, tend to constantly drain current from the battery? More than what the product by itself would (due to efficiency being
Charlie Pechiar
No since the Batteriser uses chips, which have a (very low) cutoff voltage themselves, an almost infinite drain, like in Dave's Indiana Jones experiment, will be prevented.
+Ernst Stavro Blofeld No, he got it right. Fully discharging batteries can make them leak. It also damages recharegables and makes them lose capacity. Your batterizer will do both of those things. Enjoy it!
+Ernst Stavro Blofeld
Rubbish. The Batteriser has to work in every type of device, including devices with microamp surrent drains like remote controls, Apple keyboards, etc.
Microamp loads will mean the battery voltage under load is almost the same as the open-terminal voltage. Even a dead battery has an open-terminal voltage of about 1.2 Volts, as clearly shown in this video.
When does the batteriser shut down? At 1.2V? That's still a full charge in a high-drain device.
I would love to see a teardown of one of those Chinese clones of the BK Precision Electronic Load and compare it with the real thing.
+spikester Story I've heard is it's exactly the same. The designer left and took all the design files with him.
I love when you start: "just a quick...." and here we go for 30 minutes!!! As aways, great video!
It would also be bad idea to use the Batteriser in a product that shows a "low Battery" warning since this circuitry only measures voltage and not current. The Batteriser always boosts the voltage up to 1.5V that circuitry would not detect a "low battery" and never show the warning. It would just continue operating until the current gets too low to actually operate it. This would be critical for Remote controlled vehicles or devices that use a battery as a backup to store data.
New phrase for doing measurments in a wrong way: "You are not up the monkey´s butt!"
Comment from a person who actually owns a Batteriser (please read whole comment before trolling...)
All the videos Dave did about this thing made me so interested that I actually, just to try it out, bought two batterisers. They were 2€, and I was curious, so...
What I could find out:
1) They actually work. Many people think that it's just a metal bracket, but they do what they are supposed to do.
2) They (mine) do work down to 0.55V. That's pretty cool for a boost converter, and yes it is a normal boost converter we all have seen at some point in our life, though it's an impressingly small one.
3) Under 0,8V, there is not a huge load of energy left in a battery (if any at all), so 800% is pretty optimistic. It is even very VERY HIGHLY optimistic..... Actually, I didn't notice any change at all in runtime.
4) Anyways, I found an actual use for these things (believe it or not!) and it is as obvious as boring. I have them in my old MagLite with the oldfashioned incandescent halogen bulbs. The one thing that really annoyed me about that flashlight is that when the voltage drops it gets dimmer. The batteriser does, surprisingly enough, effectively prevent on that. But, till now, that's about the only use I found for it, and because I also own a way more efficient LED flashlight...
5) I am still waiting for ElectroBOOM trying to electrocute himself with 100 batterisers with depleted batteries.
If Batteriser had ANY sense, they would send Dave a unit to test.
However, I get the feeling that this will never happen.... anybody with me?
They won't because they're afraid. If their product wasn't a scam they would gladly give him some to test.
Thoroughly busted! I love your channel mate! I've just discovered the channel a few days ago and already watched several videos and learned a lot. Thanks for making great content!
Very happy to see our joystick make a cameo appearance in the video :P We have some cool stuff going on Dave, you should visit some time.
I suppose part of the problem could be that the general public has been trained to test their batteries in open-circuit, back when all the manufacturers had those little testing strips on the sides of their batteries.
Those testing strips load the battery, otherwise they would always show the same voltage even when the batteries were dead.
love when dave use these super old videos that i have Never seen before anywhere
Has anyone confirmed that the guy in the video is a professor? As I am pretty sure that the facility department head would have more than a few strong words with him.
No idea about that guy, but sadly the guy behind battritiser really is a professor of something relevant, so definitely knows his product is bollocks.
+Matthew Wagg you may well be right Matthew if he was genuine you would think they would include his name as someone who endorses the validity their product.
+andrew mcneil Probably as much of a professor as the Labcoat+stethoscope-wearing people on TV, endorsing products, are legit doctors.
+andrew mcneil Does a Professorship in stupidity and a Masters in "you're doing it wrong" count?
+andrew mcneil The batterizer folk are complete and utter noobs. In their "Comparing Constant Power Supply with Batteries" video the guy says "This monkey uses to batteries in series" to try and sound all professional to the punters hoping that they're easily fooled. SHOW ME A MONKEY WITH TWO AA OR AAA BATTERIES IN PARALLEL...LOLZ!!
I can see the batteriser reply to this already.
"so he discharged a battery to 0.8 volt, then claims this is the same as a battery with 1.2V 'energy' left.
Dave, have you seen Batteriser's latest video? It seems to be a response to your previous video. Their point seems to be that the fluctuations in voltage due to the irregular demand for power of some products can trigger the batteries to momentarily drop below the cut-off voltage and stop working.
9:24 I can see the gif here :D
+Claude Wakes makeagif.com/ORnV3v
+Claude Wakes
GIF? What is it, 2007? Webms have sound and the narrating under that part gives it the core
Then tell me how many websites support Webm? Do phones support them?
Well,i made a gif, get over it, or go make your own.
+EEVBlog Thanks so much for this. I don't think these videos are excessive at all. I learned a lot. I am by no means any more than a spectator when it comes to electronics, but I have been watching you for a loooong time. I have never even soldered a decent joint and I knew why that test was flawed just from watching your other battery videos in the past. You absolutely do make a difference and I hope you remember comments like this on the days you just don't feel like making videos :)
Note that this is similar to checking a dead car battery. if there's no load on the battery, it'll still read around 12 volts. However, turn the key and "tick"... nothing!
Always enjoy watching your debunking videos! Even though you don't skimp on the technical details, you put the facts across clearly without using fancy sounding jargon to confuse the viewer. Keep up the great work!
+himselfe Thanks.
Do many other folks still use many alkaline batteries? I'm searching around the house and I can find only a few products. The only ones that truly concern me if they die are smoke alarms and my mouse.
can you comment on their last video about current surges and the 80% claim? I just watched 20min of the guy asking the engineer what the average value of every single thing was for no reason.
+Prastt yeah that part of the video was pretty dull
+Prastt The 80% claim is pure bullshit. It simply isn't true. It's based on a dumpster-dive study that shows that some people throw perfectly good batteries away when (e.g.) they go away for a weekend and want to be sure they have brand new batteries in their camera (or whatever).
This doesn't mean their camera couldn't use up the battery, it means they deliberately threw them away. That's an important difference, but it's what Batteriser is basing their claims on (batteriser is basically saying that *all* the batteries in dumpsters are thrown away because the owners thought they were dead)
Current surges? Does your phone keep shutting down suddenly when you touch the screen or turn it on? Nope, because real devices have things called capacitors in them to smooth out the bumps. It's electronics 101.
+Fungus The Bogeyman thanks that makes sense. True one of the examples was a train that's basically a dc motor without any filtering.
You can sometimes tell a flat-dead cell from a half-dead one by checking with multimeter: if the truly open-voltage measures the same (down to milivolts) as when hand-loaded (sweaty fingeurs across the battery poles while holding the probes)
Forget it, Batteriser already dropped that argument.
Now all of a sudden the main argument are the current peaks which the batteriser compensates for...
Dear Dave!
You both have right with Batteriser :) Batteries are different from power supplies :)
Battery voltage will drop after you apply a load (even a load for which a battery is designed). On the other hand, good power supply, while loaded with designed load should not change it's output voltage. While designing battery operating circuit you should assume, that battery voltage will vary as hell, while circuit designed for a power supply, may expect constant and stable voltage.
In a company I worked for, we assumed that battery voltage may vary from 0,7 to 1,6 V per AA alkaline cell. And yes, we used boost-converters to extend battery operating time :) Alkaline cells have much lesser internal resistance (even if discharged) than carbon-zinc cell, so in case of alkalines boost converter may help.
+EEVblog Have you pre-ordered a Batteriser so you can do some tests on it when it comes out?
+Aden McKinley pre-order??? He'll probably end up with a few in the mail-bag from viewers/fans
+Aden McKinley They offered him a whole batteriser set for review. He refused.
+Ernst Stavro Blofeld When was this? last I checked he said, "I would love to get my hands on one of these"... what changed?

+Gavin Crouch ThatRrnstguy is dodgy
How is what theyre doing legal? I thought we outlawed selling snake oil years ago...
+Kakunapod This is not snake oil, their product is just a boost converter and it works, but their claims are misleading, it's a scam, I just want to see them go up in flames, they even had the nerve to try and prove Dave wrong, but as we see here they got destroyed one more time.
Gordon Freeman I think youre being a little generous. Their claims are not misleading, they are wrong. Some of them are just misleading, but theyve made plenty of wrong ones as well.
Kakunapod
They wouldn't be in this mess if they were honest about their product and just said it as just a boost converter, the "up to 8 times more battery life" is bullshit and they know it.
Can you make a response to the new batteriser video that came out 6 days ago which explained the batteriser in more depth. I would like to see your comments on it.
+pa0070707 I am just looking at that video and at 9 minutes into the video the CEO shows that he does not know the difference between voltage, current, power and energy - even worse, he claims that the critics don't understand these terms...
+pa0070707 this appears to be the paper the CEO is citing. Interestingly he claims around 14:00 that he himself has come up with a spice model of the battery...
www.ni-cd.net/accusphp/forum/docjoints/ID2051_Modelisation_decharge_batteries_Pspice.pdf
+Uwe Zimmermann Isn't PSpice a bad way of getting solid results? I was told during my engineering course that it's good for rough work but it doesn't take into account other variables that could influence the outcome.
+Uwe Zimmermann
But he holds 500 patents :)
+pa0070707 This is a slap fest. Both them and EEVblog are wrong. It's absolutely true that using an uncompensated PSU is an incorrect way to test device cutout, that's why professional hardware battery simulators exist.
It's also perhaps incorrect to state the dc-dc converter product would overcome ionic diffusion losses of capacity, since it must inherently draw more current to boost the voltage for a set power, as per P=IV.
The energy left in a battery is as well of course an integration of the voltage supplied at the current drawn, so him coloring in those alternate parts of the graph is definitely disingenuous.
And finally, neither of them are mentioning or using a coulomb counter, one of the actual ways to precisely measure how much charge is entering or leaving a battery.
"If you can't wow them with brilliance, dazzle them with bullshit" - Batteriser
I doubt I'd like Batteriser's cover of "She blinded me with science" - theirs would be called "They tried to blind Dave with bullshit".
Dave's video is direct to the point with fully functional equipment that was a true method and from my observation as an EE, I totally agree with Dave. The sad part about the Crapperiser is that it's one of many snake oil companies that Silicon Valley is being flooded with and even experienced investors are falling for crap like it. What I really thought was laughable about that Crapperiser video was all of that fancy video production, yet a desk full of non-functional items along with an invalid method performed by an imposter.
We need more channels like EEV and "The Signal Path" to counter this type of nonsense.
The best type of internet arguments include Dave.
DURALOCK means that battery won't discharge itself when it, for example lays on the shelf for quite some time, it DON'T mean that it won't leak if it's discharged to 0..
I find you coarse, vulgar, exceedingly energetic....and massively entertaining (the accent helps a bunch). My hat (if I actually was wearing one) is off to you, sir. Like Big Clive and Julian Ilett, I've learned more in a week of watching your videos than I ever did at ITT Tech.
That is because they are Alkaline right? Which maintains high voltage as the energy is drained, unlike "heavy duty" and "super heavy duty" batteries which their voltage drops as the amps get used up.
why not do a video on NiCd memory effect? would be interesting
Poor Julius would be turning in his grave to hear that Cadbury's no longer uses a full glass-and-a-half of milk in their chocolates :-(
can we just go back to that jump cut around 2:37... what exactly does Probes "take roughly"?
+bmw2go11 I am just glad that Dave didn't stuffed the bananaplugs up Probes back end.. :P
It would be interesting to see how different Eneloop class batteries are compared to alkaline cells.
That also explains why pulsed load works longer on a half-dead battery, like the 3 transistor single cell LED flasher. Thumbs up, thanks for sharing.
You should take a look at Duracell's own built in "Powercheck", It works by loading the battery and heating a liquid crystal type temperature strip to show remaining capacity, I think they know what their doing.
A good talk that I am curious with is why do batteries leak when they reach zero energy? Is one of the terminals start to eat out of the battery? Also, is this why we see some batteries we leave in a device for years and come back and see corrosion?
+Kairotan Some gas is usually generated in the battery from electrolysis, which can rupture the seal. Corrosion from outside or inside sources may also occur. Wikipedia should have a section on it under "alkaline batteries", with failure modes for different chemistries potentially being different.
The Batteriser Team would probaly just run away and nobody will hear of them. I'm telling ya this is one of the best scams that happend in the 21.
There is another 85 years to go in this century. I have unshakeable faith in my fellow man to top the Batterizer at least a few times during the remainder of this century -- probably with dubious technologies we have not begun to think of just yet.
In the first half of the prior century radium tainted water was sold as a health elixir to improve sexual prowess...and continued to be sold until some fool consumed more than a thousand bottles and lost his lower jaw in the process (the very definition of ”sexy”). Now who would have thought of selling, much less ingesting, radium as a health elixir? My fellow man...ain't we genius?
+the real illuminati Just like the morons at Solar Freaking -Roadways- Scam.
one final test, 2 identical led flashlights side by side same batteries except one has batteriser. Time lapse till drained. I know it doesn't work, but would make for a good test.
the only thing I think this batteriserr may be useful for is perhaps an led torch or very badly designed product that has a cut off voltage set too high. surely if using it in say an led torch you would be trading operating time for brightness ?
+TRDreams
Ummm.... exactly the opposite. Any decent LED torch will already have a boost converter built-in. That's why they stay bright and die suddenly.
mines a £30 handheld lamp so should be decent one of those ones they use in garages, it certainly fades out slowly over time. Might have to pull it apart to see if there is indeed a converter! I'll also find the model of it
Is it safe to assume that all battery types (lith-ion, lead acid, nicad, nimh, etc) exhibit this behavior of floating up to a higher voltage when not under load?
The biggest battery scam is that Duracell batteries are better than generic random store brand alkaline batteries that cost 5 times less.
Depending on the size, they should instead market the product to people who may have a number of flashlights which do not have regulated outputs, or make retrofit devices for use with flashlights with unregulated supplies. That should at least keep the light brighter for the duration of the battery life.
Of course the folks at Batteriser know these things, they are just counting on their customers *not* knowing or being able to prove it. Thanks for the clip of Julius!
Simple: By the time the battery reaches the cut off voltage for the product it's powering, there is practically no energy left in the batteries since most products have such a low cut off voltage. Nothing more needs to ever be said.
What _is_ misleading is taking the manufacturer's discharge curve and assuming it's showing the battery's open-circuit voltage, when in fact it's showing the battery's voltage when under load. And that's exactly what the batteriser people are doing.
What I have learned from these videos is that a battery's open circuit voltage is pretty random and tells very little about how much charge is left in it (which is the crucial part). You could have an almost empty battery showing 1.2V when measured open-circuit, but that really tells nothing. It won't run a device at 1.2V, but something a lot lower.
1 year later and have Batteriser tried to fight their corner?
Batterizer hired an online company to thumb down all his videos on the batterizer/bateroo. He has a video showing something to the tune of 500 dislikes coming from vietnam on the same day on all his batterizer videos.
WooHoo! More'Batteriser' debunking. My son and I just love it when Dave debunks these kinds of things. :D
What cracks me up is that they didn't put the batteriser on those dead batteries to prove that it would make those batteries work.
Looks like Batterizer has been paying for more dislikes... not nice Batterizer. Thanks Dave. This is why when I check my batteries, anything less than 1.3V open circuit (just for stupid VERY rough estimate) usually heads for the flashlight bin. Flashlights work great with such low energy. Another great video Dave.
That's why it's important to have two multimeters.. I would've thought that my multimeter was busted! Great vid!
Will someone please identify the B & W film clip it's driving me crazy.
Hey Dave, I stumbled onto your channel a few days ago, and just wanted to say that I appreciate you going into such depth debunking this batteriser product. I'm a trained computer engineer, but have never really spent much time studying batteries, so when I heard about the batteriser, and read through their marketing materials, I thought, "Wow, that kinda makes sense that it can use the extra voltage energy that is left after the device cuts out at 1.3 volts, etc." Your previous two videos went above and beyond in proving that the cutout voltage for most devices is nowhere near that high, making any gains from the batteriser negligible. The fact that they're making these strawman argument video replies is hilarious. Keep up the good work, mate!
Will the batteriser fool a smoke detector. I would love to use rechargables in the smoke detector. When I put 2 NIHM AA batteries in, within 15min the detector starts saying "Low Battery".
im interested what the batteriser actually does. why don't get one and test it out
+Yik Wai Donald Leung you can not order it "directly from stock" as of now. You would have to use kickstarter. As usual with kickstarter: Who knows when they ship it? I mean: As always stuff can get delayed for a good reason. But... Donating 40$ to them in the hope that they can deliver, just to prove them wrong... THEY are making the claims for an unreleased product - they have the burden of prove.
is there any method to go through the videos on this chanel , any advice or recommondations ? please
Thanks for the great explanation Dave!
I find it funny in that the last video that Batteriser uploaded, they suddenly are (partially) using a Rigol DS1054Z and have a Hakko FX-888D sitting on the bench. Very similar to what Dave has sitting on his bench...
oh. i love products that practically run from static electricity. :D (like calculators, clocks, and arm cortex M0)
Would it be possible to to maximize battery energy extraction by using some king of pulse drain scheme with a storage capacitor to provide a smooth voltage to the end device? I think it is done with small lithium batteries but could it be helpful with alkaline batteries?
Well, Dave is certainly getting more juice out of this Batteriser than anyone ever thought possible ;-)
+1 Awesome Aussie points for the Julius Sumner Miller clip Dave !
Why don't they market the Batteriser to be used with "dead" batteries in remote controls, calculators and so on? It seems it would actually somewhat work in such applications and that would also be honest... Now they are only losing cred for lying... Or?
+Maria Engström a) Because most low power products like that already do a pretty good job at working at low voltages.
And b) You won't get that much extra life from them in the scheme of things.
This is why automotive batt testers have a load test function. And they still can fail to tell how the state of the batt is.
this video makes a clear point, its less "testing under load" than "testing under same load".
You should have some mythbusters-like signs made out of PCBs... "BUSTED", "PLAUSIBLE", "CONFIRMED" but I assume you'd only ever bother with one that ends up in the first category....
Exactly. It's like saying "My car old dead battery is alright, it reads 12v" then you wonder why the bulb or starter motor you just tried running off of it acted as if it was in open circuit and the voltage reads under a volt closed circuit :P
Just tried testing my Metrix MX54 multimeter 9V battery.
The TESCO VALUE battery is at 8.5V open circuit, turn on the meter and it drops to 7.8, fire up the back light and it drops to 4.1V. Also the screen dims and the low battery waning activates.
The TESCO Extra Long Life battery is at 7.5V open circuit, turn on the meter and it drops to 7.3V, fire up the back light and it drops to 6V and continues dropping.
In conclusion this not only backs up what Dave says but also demonstrates that the TESCO Extra Long Life battery is still useful despite having a lower open terminal voltage making open terminal meserment useless for even getting a rough idea if the battery is still good. The multimeter used for testing the voltage of the battery's was a Thurlby 1905a in 6 1/2 digit mode.
If I had gone on open terminal mesherment I would have chucked the wrong battery. Even with out the Bateriser debunks these videos have been very interesting and informative. The Bateriser just makes the video even funnier and makes it more entertaining. Thanks Dave, once again you have helped improve my electronics knowledge.
Hey ,how do you like the probe master probes?
You forgot to take one thing into account. The batteriser people would have to get new jobs if people knew the product was bad.
Thanks Dave for putting this out to bust these products, good on ya!
Batterizer probably used carbon zinc cells in their video, its trivial to get them to recover to like 1.25 but then drop the moment you sneeze a bit of current on them. Much higher internal resistance.
I would love to see the reaction of those people who spent $40+ on the batteriser and could only get a few hours more life out of the batteries.
duracell battery and energizer specs?
You know how Duracell have a handy Powercheck feature? I have not found a rechargeable with the feature is it because the rechargeable stays at 1.2v for a while? Is the powercheck accurate? I guess it puts the battery under load?
+Knuckles the Echidna Yep, it loads the battery with a heating resistor and you see the strip change color, if heated enough. Rechargeables hold almost constant voltage to the very end, so you could only detect, that it is dead if you put a Powercheck strip on it.
I have not seen one of those Duracell powercheck strips in ages now that you mention them...I had almost forgotten about them despite regularly buying both Duracell and Energizer brand batteries for decades. I did not know they still existed.
But as bumv2 states, the powercheck was simply a long film resistor with temperature sensitive liquid crystals (like those thin strip thermometers used on aquariums and such). The heat generated both provides a proper test load and warms the temperature sensitive liquid crystals creating a simple bargraph effect. A clever ultra-low cost battery tester.
I have no knowledge of electronics beyond knowing what batteries are rechargeable and which aren't... yet here I am.
"...because the batteries don't measure 1.25v per cell when you stick them back up the monkey's butt."
This whole debate notwithstanding, that's pretty much the first time I've ever heard THAT mentioned on a TH-cam video...or anywhere, really.
LMAO.
Even in my electronics kit I got at the age of about 12, they explained that the voltage under load is different from the voltage without load. Well, as usual: If a claim is too good to be true, it probably is bollocks!
We need to get our hands on a batteriser when they come out
will there be another part of samsung lcd tv repair?
+ZamaskowanyWolnościowiec No, unfortunately. Dave ruined one of the boards when he placed it in a Soldering Oven. The cable connectors melted.

How can you measure the energy in a cell?
I would love to see Batteriser produce another video trying to show this video as wrong. Not possible, I believe you have won this battle. Also some great information on why batteries can recover voltage like they do. Its a very interesting topic seeing how more and more products are battery powered. I would like to see more videos on designing battery powered products, rechargeable products, and how the recovering voltage of batteries effects your product design.
Thanks again for all your videos, and good "trusted" information
