Still no interest in even the simplest test of the reverse diode heating problem after the first Batteroo in a chain shuts down? (all the current passes through the intrinsic diode with a 0.6V, 0.8V,
![Huh? ???](https://www.eevblog.com/forum/Smileys/default/xhuh.gif.pagespeed.ic.6Nvt7O8a11.png)
?V drop)
Still no interest in seeing if the Batteroo can latch up?
It just really puzzles me. The Batteroo may have bigger problems then its efficiency, and yet all we talk about is Garmin GPS's and toy trains. Not sure the last time I have seen the accuracy specifications for a toy train. Do Keysight sell a reference calibrated toy train? It is also just so easy to fake a test - even one that is continuously recorded. Flatten an alkaline battery, recharge it back to 1.6V, make it look like it is in a sealed pack and you now have a perfect battery to fake a short battery life. I totally trust Dave's toy train video tests, but in general, I look at most of these tests and have more questions then answers. I am left feeling - "if only there was a technical forum somewhere that could characterize the Batteroo according to calibrated lab-type measurements".
Toy trains and GPS's is where Batteroo want the argument to be, because they can keep the argument going around in circles until the general public is dizzy. If they can fool half the people half the time, they are billionaires.
If it turns out the maximum current of an AAA Batteroo is 300mA in a multi battery device because of intrinsic reverse diode thermal problems, that is pretty huge, since Batteroo have never wanted to specify any limits. Maybe there is no problem at all. No one knows at the moment, and I suspect that state of affairs suits Batteroo perfectly.
