- Dave shows why power supplies are no different to batteries when determining cutoff voltage, busting the claim of Batteriser using their own monkey experiment.
It shows the incorrect method used by Batteriser to come to their false conclusion.
Discharge testing of alkaline batteries is performed, and correct probing of the monkey toy shows that the cutoff voltage with both batteries and the PSU are identical, and does take into account the electrochemical ionic internal resistance of the battery.
Dave explains why using a PSU is the standard industry technique for measuring product battery cutoff voltage.
Also discussion on ionic resistance recovery graphs and energy density in a battery.

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😏👉
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.
"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.
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.
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.
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!
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
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.
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!
New phrase for doing measurments in a wrong way: "You are not up the monkey´s butt!"
"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".
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 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.
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.
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.
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.
Forget it, Batteriser already dropped that argument.
Now all of a sudden the main argument are the current peaks which the batteriser compensates for...
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.
I love when you start: "just a quick...." and here we go for 30 minutes!!! As aways, great video!
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.
We need more channels like EEV and "The Signal Path" to counter this type of nonsense.
this video makes a clear point, its less "testing under load" than "testing under same load".
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 :-(
I have learned so much from you today. You are a fantastic presenter and teacher. No matter what never stop doing what you do!
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.
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.
The best type of internet arguments include Dave.
The biggest battery scam is that Duracell batteries are better than generic random store brand alkaline batteries that cost 5 times less.
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.
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.
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.
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.
love when dave use these super old videos that i have Never seen before anywhere
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!
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.
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.
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.
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.
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 UA-cam video...or anywhere, really.
LMAO.
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.
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)
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!!
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!
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.
Now you need an actual Batteriser to test, just to put the final nail in the coffin.
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..
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
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!
Batterizers can be used for nickel - cadmium battery that provides only 1.2 v can be raised to the 1.5 v that some appliances need. That would be a sensible sales argument.
You need to get 2 batterisers, put the batteries in the monkey and drain down until it cant drain any more "without the batteriser" then put them in with the batterisers. Because that would be the final nail.
oh. i love products that practically run from static electricity. :D (like calculators, clocks, and arm cortex M0)
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.
+EEVblog I can see trolls taking this company to court over mis-advertising (8x longer)
Well, Dave is certainly getting more juice out of this Batteriser than anyone ever thought possible ;-)
I'm looking forward to them trying to "refute" this.
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.
+1 Awesome Aussie points for the Julius Sumner Miller clip Dave !
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 getting into the chair hopping levels of fun.
You forgot to take one thing into account. The batteriser people would have to get new jobs if people knew the product was bad.
That's why it's important to have two multimeters.. I would've thought that my multimeter was busted! Great vid!
WooHoo! More'Batteriser' debunking. My son and I just love it when Dave debunks these kinds of things. :D
Their inventor and co founder was a former "general manager and VP" and he uses this to qualify himself. THAT on it's own rings alarm bells, what about any actual engineering background?????
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.
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!
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.
you learn about the batteries internal resistance and the changes in the chemistry at 5 years old when your trying to eek out every last drop of power to play your game. I used to put them on the fire place to warm them up as you got an extra 10 minutes playing time. this really is page one stuff...
That electronic load with Keysight 7 1/2 digit meter probably costs more than all their marketing department funds ;)
+kroplaaaa Wrong.Keep reaching
You know how they did it, right? They put the batteries in the monkey until it wouldn't run any more then heated them up in their pocket (or with the well used soldering station on the desk in their video) to make the voltage recover to a high voltage. Thumbs up to you Dave! Bust that BS!
When I researched that "product" it reminded me of the perpetual motion machines of the late 70's. They will disclose the actual science behind this new technology shortly but take their word it is cutting edge, revolutionary, and a real game changer, all for the low low price of...
act today and we will double your order for free (plus shipping and handling).
Who really falls for these type of "offerings"?
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.
We need to get our hands on a batteriser when they come out
We have a bucket of used batteries in our office which were used in common IT office environment, and when I have a died battery in my car alarm remote, I just take one from the bucket and enjoying for a couple of _months_! So, think about the usage funnel for your batteries, like flashlight->radio->remote and talking about _Time_ that battery being useful, it's actually can be 2 or 3 times more!
PS: Interestly, I can use AA battery in my logitech wireless mouse for a month after it has "died" in apple magic mouse
I wanted to comment "science of stupid", but Batteriser is not stupid, stupidity is accidental, what they did is misleading on purpose, it's a lie.
This is basic electronics. Its shocking why don't they understand it.
Thank you very much for the very video. I have learn a lot.
Pulse loading actually allows to extract more energy out of a battery.
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 Monkey Under Test hahahahaha!! - shown on the schematic as MUT presumably?!
+Alan Cordwell MUT is standard industry terminology.
+EEVblog As a Test Engineer I can confirm :)
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 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.
Thanks for the great explanation Dave!
Thanks Dave for putting this out to bust these products, good on ya!
Next step, getting those batterisers!
Something obvious just occurred to me: use cells in parallel to get more usable energy. Less internal resistance from the battery of cells in parallel, so less energy wasted heating the cells.
Presumably, this means that putting e.g. seven AAA cells in place of a D cell would be more power efficient. (The cost of manufacture must make this uneconomic. Maybe it would be viable for NiMH, where the cost differentials are more favourable.)
Hey they have a new video where power is the area under the constant current curve :D And they show how a "well" designed device stops operating after a high current surge and they do NOT show how a tiny piny batterizer inductor solves the problem ! Bust it, bust it, bust it !
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.
+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 :)
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...
16:30 that Pilot G2 though. Great choice for a writing tool.
Best video about a monkeys butt, not the toy but Batteriser! I love how you tried not to say it at first, then got so mad at Batteriser or what is becoming known as "Batter-liers"... i digress - of course there selling "cogs" in an attempt to fleece people who don't know better and see an amazing new gadget on Indiegogo who should be smart enough to pull down the campaign until Batteriser can prove their findings.
Which we all know they cant... Even more surprising is that energizer or duracell has not served Batteriser with a cease and desist order for false claims against there products.
Forgot Indiegogo gets 15% of the funds so why would they stop 5,679 people from being ripped off...
Dave keep telling them like it is I'm sure they will listen when the charge backs start to flood in...
I have a childhood memory of sitting under a table or bed covered with some blankets or so and having a flashlight. I could see the light dying down completely and knew that if I turn it off for a while it will give me another short flash of light (the battery recovered).
Given that we moved away from that house when I was 5 that means that a
Dave, you need to buy the batteriser and do a tear down, even though there isn't much to it.
LOL, look at 22:04 in the video. When Dave says "oh no, he's gone... he's gone...", Probes the monkey just nods and approves. :)
When you market snake oil you don't say it doesn't work. 10/10 for their marketing
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....
21:35 i will never forget that face with those probes in his.....
Anyone disliking this video is obviously an uneducated Batteriser fanboy
with ZERO basic electronics knowledge or common sense.
