What if the circuit's shell is a novel capacitor?
But it's not....
AFAICT, that's hearsay until confirmed.
It is confirmed, time and time again, by Batteroo in all their marketing, interviews, patents, etc.
It is a simply a DC-DC boost converter.
I don't know what is ambiguous abot them stating 80% that the energy of a battery is unused or 800% more life which clearly refers to any single application. Dave has explained numerous times how using a benchtop power supply for closed circuit voltage is correct. Feel free to cite what problems there are in using a benchtop power supply to determine cutoff voltage.
For purposes of a battery powered device, a benchtop power supply supplies essentially limitless current. Batteries have performance limits on their current output.
Technically correct. Using a PSU to simulate a battery is not in theory correct, but it's so close for the way most modern practical products are designed and implemented (DC-DC converters, copious decoupling etc, the way the low batt detection works etc), that it's an industry standard technique for doing so. Unless of course you have some specific niche product application that it really does make a difference.
And even when not true strictly true, using a PSU gets you a pretty good ballpark estimate.
But the average product Batteroo are talking about they are equivalent techniques.
Sadly, many consumer electronics products are not designed for optimal battery performance.
Yes, but the
majority are designed to get at least decent performance with their intended batteries.
Go out and test products like I did and you'll find that's the case.
Batteroo have had 5 years to work on this, have millions of dollars on the line, and they can't even produce a list of products that are poorly designed like you mention.
Their big test with the GPS has been thoroughly proven to have been incorrectly implemented and/or deliberately deceiving.
