EEVblog #751 - How To Debunk A Product (The Batteriser)

[AlxDroidDev]

If it weren't for Dave, by now the rahparvar (sorry if I spelled that correctly!) brothers would be claiming that the batteriser could cure all sorts of cancer, AIDS, phimosis and ingrown toenails.

[EEVblog]

In the case of toys, which again, was a use case specified by the company, kids don't care that their train runs a few percent faster, if it stops 50% earlier.

Yep, and I posted this in the testing thread, but will repost here, the result for the toy train:
About a 10% velocity difference with the Batteriser. That would be imperceptible unless you had two side-by-side.

[Hensingler]

This is the only device I can think of that would benefit from the batteroo...

$19.99 worth of batteriser 'D' sleeves to make a $14 pump work better?

[Hensingler]

Dumb thought for today....

After all the batteriseroo drivel about cut off voltages you would actually find more battery life extending applications for the thing if it were a buck-boost converter with say 1.0v output.

[Luminax]

With Batteriser : 3.3333 LPM (Laps per minute)
Without Batteriser : 2.8571 LPM

What's that track like, one meter or something? let's assume it is.
1 lap = 1 meter
Batteriser : 3.3333 m/min = 0.0556 m/s
No Batteriser : 2.8571 m/min = 0.04762 m/s

speed difference ratio : B/NB => 1.1675 => 16.75 % faster

total lap :
B : 350
NB : 510(?)

difference ratio : B/NB => 0.6862 => -31.37%

... okay, I don't know what I calculate these for... I was kinda bored

Not to mention; If it's for camping use, why not just get a 12V automobile powered one? For less than the cost of the Batteroos. Eg:

Sorry for the tangent again.

[AlxDroidDev]

With Batteriser : 3.3333 LPM (Laps per minute)
Without Batteriser : 2.8571 LPM

The way I see it, Luminax, we have this:

169 minutes and 508 laps without Batetriser
94 minutes and 351 laps with Batteriser

B : avg speed = 3.73 LPM
NB : avg speed = 3.00 LPM

This is what was already expected.

In short, Batteriser is pretty much like me when I was 18 years old: I could go quite fast, but I wouldn't last long!

My main point was to say that this is a functioning device afterall (leaing out oll of the claims and intended purpose) and can be used on some cases. One example is that mattress inflator someone posted that relies heavily on battery voltage. Another usage are some cheaper LED (head)lamps that have no regulation and would stay bright a lot longer with Batteriser.

Dave showed in the toy train test how much more life a Batteroo gives you from a a supposedly dead battery in a passive load application, and it was miniscule. You're better off spending your cash on new batteries than a pack of Batteroos.

Dirt-cheap unregulated lamps are one situation where I could see it being useful, but again, a LED lamp with regulation is cheaper than a set of Batteroos! And then you get more important battery-saving features like a half-brightness mode.

Be careful with lamps, Ysjoelfir reported that Batteroo actually kills some of them:

Spend an extra 5 dollars and get the mains powered version. ($19.95 from bunnings)

Damn, maybe I should have included this in the video?
I was going to include in another one, but it's not going to get done this year.
Sorry, but I might pull this video and add that stuff, otherwise it will be weeks before people get to see it.

I just wish you had included all the extra time the non-Batteroo train ran in the side-by-side timelapse summary, because as we all know nobody reads the video descriptions so I think a lot of people will get the wrong impression from it.

I already posted some sums on that. Amazon Performance alkaline AAA are 26 cents (in a 36 pack). That is more than 9 per battieriser sleeve. If the batteriser extracted 10% more life from a 'dead' battery you would have clip and unclip it from 90 batteries just to break even. That is 90 extra battery changes with clip/unclip before you save a cent and the batteriser would likely fall to bits before that.

edit: oops 81 extra changes (because you would have to change the extra 9 you bought).

Much better video rendering now!
Includes a cameo from Rodney Dangerfield!

I did, and it's still in there at the end of the video.

Burning flesh!

That's two reports now.

The smell of bullshit mixed with the smell of burning flesh must be rather interesting. 

Maybe this has already been talked about or tried but it would be interesting to try these with rechargeable batteries.  They might actually have some benefit there.  I find a lot of devices don't like rechargeables because of the lower voltage, especially devices that use multiple batteries as the lower voltage adds up.  Ex: something that takes 4 AA's expects 6 volts and will only get about 4.8 with typical ni-mh cells.  This is partially fault of products though, would be nice if they would design them with rechargeable batteries in mind and just make them tolerate the higher voltage of primaries too.

First of all, i think that Batteriser does not deserve all the hate it gets from here.

Yes they do. They deserve every last bit of it for multiple reasons, eg:

* The Batteroo Brothers know it doesn't work. They've known it for ages, long before they did the IndieGoGo campaign. They know it couldn't provide 800% extra long before they put "800%" on their web site.

* When Dave made a debunking video they started a hate campaign against Dave, including paying a bunch of Vietnamese people to go and downvote his videos.

They're not a bunch of poor deluded engineers, it's a deliberate con. Their product is "Snake Oil" and they know it.

[ErikTheNorwegian]

Well, the batteriser fails, not suprising.
But, isnt the batteriser ment to be put in place AFTER the battery is empty and dont work?
Not on a fresh new battery..

So the real test should be:

1.Use the battery until device don`t work.
2. Put the sleeve onto the battery and then see how long use you got.

Having it on the whole time will make a "overhead" used by the batteriser itself.

That it will fail even here, is obvius.. but for doing it right.

Watch the video, Dave did that too.

He put a "dead", batterood battery in a torch and it ran for 16 hours.

PS: Batteroo's own FAQ tells you that you can put it on from the beginning...

I actually might know products where the batteriser might be useful. Canon powershot cameras. When they move the lens, they shut down with low battery, and they dont like rechargeables too much. So I guess high current+ESR triggers the undervoltage circuit, it wouldnt with this.
Anyway, this is still twice the price of a re-branded Eneloop battery. Totally uneconomical.

So you'd prefer a corrupted SD card?
