That chart above is pureironyjustice.
Over a year ago, Boob originally claimed that battery powered devices cut out at 1.3v or so.
Here we see that the Batteriser/oo itselfcrapscuts out at approximately 1.3v.
Wait a second. That graph shows the output voltage of the batteriser. The input voltage is below 1.1V at that point. So the batteriser in fact helps to keep devices that cut out at 1.3v or so happy as long as possible.
And would be cool to see your SMU in action to do the characteristics curves for efficiency, input/output voltage curves etc. I know you don't like to write software or setup some complicated test, but some viewers (like me ) might be interested how easy (or complicated) it is to control the outputs of it and read the measurements from a PC with a script, in comparison to EEVblog #957. Once you've done this, the experience you gained from it might be useful for other projects as well (uSupply?).
Its relatively easy to do when you have a multichannel SMU, there are some Keysight videos here:
@Hugoneus: I just subscribed your Youtube channel, your TSP #36 video is really interesting and informative. Would like to see how you can script your two Keithley 2450 SMUs that you have. The graphical flow diagram interface looks a bit cumbersome, I would be faster writing some lines of code, but maybe it is useful. I hope someone sends you some Batteroo sleeves.

Thanks, I didn't expect that Keysight manufactures a dedicated instrument like the N6705B just for this type of applications. But looks like there is some demand for it. I guess if you develop or have to test lots of power supplies, it doesn't matter that it costs $7,765 (at Newark).
But for this price I would have expected better software. As you mentioned, looks like it doesn't measure multiple operating points, just one sweep for one current, or it might be complicated to automate it with the software. Even the output power is displayed inverted and the graph doesn't look very nice, missing labels, and ticks and values on the axis.
Keysight offer BenchVue with the paid Test Flow option as their software for automation:
My 10mA test is finished, the sleeve lasted for 10½ day. The first 10 day the voltage was above 1.3V, the last ½ day it dropped below 1.1V before the sleeve quit.

But again, props to them for doing a much better video test demo than they previously seemed capable of.
I have to say, Batteroo, after learning and getting tips from this blog, have finally done a video demo test that covers off some of the very basic requirements. For instance they're comparing like for like, they show the brand new cells being taken out of the pack, they show the equipment and the timer, and it's in one take, and results are shown in a clear chart. Props to them for that. Pity they're still using that awful oleaginous-voiced woman to do the narration. And they stopped the test when the non-batteroo'd torch was still going, and still probably had hours of dim glow left in it.
And yes, as expected (and not denied by anyone), their product works as a boost converter (albeit one which can't maintain a steady fixed output voltage), and they've chosen the one-in-a-million device where using the Batteroo is maybe valid: A dumb, old-fashioned incandescent torch with no built-in boost conversion which runs on a pair of Alkaline D cells. Basically a switch and a bulb in a can.
Trouble is, the world has moved on. No one I know still uses crappy old incan torches anymore (even my parents who are in their 70's and aren't "techie" at all). Nowadays, everyone uses LED torches with fantasic buck/boost converters built in, multiple modes, far more efficiency and brightness, and much more robust than the old incan torches like they used to use in the WWI/WWII era.
Again; of course Batteroo works in this ultra-limited case scenario, but it's solving a problem which simply doesn't exist in 2017.

Can you post the data/graph please?
"A fairly low current test, the Duracell without sleeve can run for 11 days down to 1.1V and for 14 days down to 0.7V.
With the sleeve the runtime is 10½ day down to 1.2V and a few hours more to 1.1V and 0.7V.
From my logfile I can see that the sleeve deliver a total of 3.67Wh, without the sleeve I got 3.02Wh to 1.2V, 3.46Wh to 1.1V and 4.15Wh to 0.7V (These two batteries are not from the same pack, i.e. the comparison is not completely valid).
In this case it looks like the sleeve delivers slightly more energy to device that only work down to 1.1V, but not anywhere 8 times or even 2 times."

Is it me, or does it look like the torch with the batteroo is focused in more of a spot on the lux sensor, versus more of a flood on the other torch.
Visible from about 1:18 to 1:27 where he is fiddling with the torch trying to get the spot centered on the lux sensor.
