The Batteriser is also interfering with the Garmins firmware design by not allowing it to measure battery voltage and use its current minimising features like reducing backlight brightness etc. to extend operation.
I think you are right, and then it really does seems like the only effect is too fool the devices own battery measurements so it doesn't show a low battery warning to the user...
Why can't they just put the batteriser on the dead monkey batteries and show us the monkey clap seven times as long as it already had.
Oh well, the truth will get out eventually...
This video just popped up, I have not watched it yet:

He is wrong about the Apple keyboard. I mentioned before that the batteries on that thing last about 2 months. And when Apple released the mighty mouse, the combination of the two, got something screwed up and the batteries lasted 2 weeks max.
Alexander.
BTW, I didn't get it when I first look at the keyboard video, but Batterafool got it wrong on the OS name, the X is Roman numeral, so OS X is to be pronounced OS TEN.
That's my 2 cents
Should I dare watch this?
Or should I wait for the Rotten Tomatoes review to see if it's worth wasting my life on?
If you put several independent boost converters in parallel or series, that would normally cause problem as well since the ripples superimpose so you'd get beat frequencies and varying amplitude and lots of other nasty problems.
Exactly. These things run at higher frequencies, one device will respond to the output of the other.
Without communicated synchronisation they have to be damped, reaction slown down, witch reduces the overall stability, specs and efficiency.

Yes, definitely. You learn in 46 minutes that devices should add a few capacitors to allow for current peaks... Oh wait, they already do
McBryce.
So, if the butteriser just compensates for high peak loads, it won't help in a torch, because that's a fairly continuous resistance load, it won't help in the monkey, because that will run down to nothing anyway.
It won't help in any older hand held games consoles or tv remotes.
It most likely won't do anything in a wireless keyboard or mouse.
It will possibly allow a discman to spin up the disc at a lower cell starting voltage, but won't actually increase the run time.
And it might allow a digital camera to take 5 extra pics...
I'm sold!

The interviewer is a computer generated voice. (in the first 2 minutes, didn't watch/hear the rest)
Makes me think of the voice in my GPS.
Oh what a fail!
Dave, looking forward to you picking apart this video. Please include cheesy royalty-free music in your response. Instead of the clacky keyboard sound, I request you use an old fashioned typewriter with the carriage return "ding" at the end of each question.
Also, could they not afford to hire TWO lapel mics?
Dave: I'm not even sure that the Rotten Tomato folks would even bother to give a note for this, they would die of borring just after 3 minutes of watching.
Also, could they not afford to hire TWO lapel mics?
No, this is not their job, they are here only to sell their ripoff of my BUTTeRUSEr PTM Edition (I have small tweak to be done before releasing it, OSH of course) so, leave the good mics to folks that only know how to do youtube videos and not EE, like dave, and leave the EE to people that know how it works...
(did that mean that they should stop doing EE and Youtube video, as dave is good at both?)

You will learn that batteries equipped with batteriser can supply peak current at higher voltage than batteries without or at least that is the implication you get from the video. The batteriser is not participating in the video.

There's 10 minutes of stating the obvious (explaining how batteries work), two outright lies, then half an hour of mind-numbing mumbling while looking at oscilloscopes trying to justify those lies (our monkey probing friend makes an appearance for this).
At no point do they put a batteriser on a 'dead' battery and show it working again or do anything obvious/useful like that.
Hey, at least they got him a proper soldering iron for this one.
Is their (cheap) oscilloscope (cheap) probe are correctly calibrated this time?
It's really funny to see that a company that should have so much money to buy cheap chinese stuff for their "EE lab"? Why I don't see any agilent/tek/... or even Rigol branded TE stuffs?
Why does their EE lab look like a cheap table with nothing that a normal EE lab should have?
There is no way to "create" a sleeve like what they claim to have done in a lab like this.
I wonder if everything hasn't been fully ODM designed by some chinese company on the behalf of the battefool company?

Oh great.

Of course not! They seem to specialise in this.
They do use a Rigol in part of the video.

something about snails, and 25 feet, which apparently 90% of people won't get, I assume that means he didn't get it at first either, I thought it was pretty obvious...

Ah, didn't somebody call this one a while back? as peak currents have recently been discussed on the forum.
I've been waiting for them to mention peak currents and voltage dips due to ESR. Let me guess, they use a camera as a test device in the video? (that are notorious for peak current issues with Alkalines)

(well, yes, but I wasn't paying much attention)
however, they claimed the GPS drew 660ma peak, dropping the cells from 1.25 volts each, to 1.1volts, and causing it to shut down...
which is interesting, because their first test showed the GPS drawing about 300ma peak when it shut down...
But then, if its dropping to 1.1volts with (660ma) ~730mw load, with an 80% efficient dc-dc converter, you're now drawing ~910mw, or 830ma at 1.1volt..... but you're not going to have 1.1volts anymore, because you've increased the load.......... we all know where this is going of course
And can we really expect a 700+ ma output from a tiny boost regulator, with basically no capacitance? Isn't that going to drop voltage just as badly as the cells are anyway?
