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?
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
So, if the butteriser just compensates for high peak loads
Ok for the DS1054Z + Tek probe, I haven't saw this video yet, so they bought some stuff since the Monkey video...
b) Due to ESR, sudden spikes in current demand can cause sudden voltage drops at the battery terminals. If the voltage drops low enough during a huge spike then the device will shut down prematurely.
[...]
Does Batteriser prevent this voltage drop by drawing even more current from the battery to compensate?
I understand his "under the curve" vs. "boxed" argument (it is basically using two Y-axis, one in volts the other in ampères it should've been explained more clealy), but this is only accurate for a constant current load
which is in my opinion very unlikely. I can't imagine a load would draw the same current at a 1.5V battery voltage as at a 0.8V battery voltage.
a) Apparently you have to include the area above the battery discharge curve when you're dealing with constant current devices, not just the area below it.
(No, I don't get it either, he just states that as a fact and gives no explanation.)
@Dave. No batteriser. You must watch it.
But, as my graph shows (which calculates power), it's almost a linear line, so mAh and Wh are practically the same in this case. In that case as my graph shows you can simply take the capacity remaining from the X axis like he is saying (the "area" part is moot).
Did they really not do any test on the Batteriser itself in a 40min video?
@Dave. No batteriser. You must watch it.
Must I?
Not enough Ripe Tomatoes yet.
Sorry, I have an appointment at the dentist to get all my teeth extracted, and he's out of pain killer and is a former marketing droid who like to talk about synergies. That's a less painful deal by the sounds of it.

The start is OK. He proves he actually knows about batteries.
I think I got it. The trick is to assume the current remains constant as the voltage drops.
It's not a common situation but it could happen, eg. powering a linear voltage regulator where the battery voltage never drops below the regulator's dropout voltage.
But... that's a situation where using a batteriser will make things much worse. A voltage booster will make sure the voltage regulator is producing the maximum possible amount of heat for 100% of the battery's lifetime.

They could have just filmed two products (a Batteriser vs. non-Batteriser) and thrown it into time lapse or sped up the video. Would have been far more interesting (and accurate).
Our local council recycle centre has big bins full of discarded batteries and I've never seen a fellow sitting alongside with a shit load of test gear and an open spread sheet, which begs the question should I go around and grab a few hundred and video the whole thing or like the rest of it would it be a lot of energy and effort for little gain.
