Can you do that with the boost set to 1.6, for a comparison?
Edit (sorry I see you already have sufficient info in an earlier post)
Hi group,
The behaviour that is predicted by my model is included in the Batter... Patent application.
https://www.google.com/patents/US20120121943
Here is the picture:
They have chosen for some unknown reason to boost the battery voltage to 1.8V
Note: they show a shorter running time with the Battery_Booster connected.

FIG. 7 shows measurements that illustrate the advantages of the various embodiments. Three popular AA battery brands, Panasonic, Duracell and Sony were chosen for the measurements. Active load circuitry that drew a fixed 50 mA current was placed at the output of these batteries and the voltage of each battery was measured over time. The horizontal access shows time and the vertical access shows the battery voltage. The starting voltage for these fresh batteries was 1.6V. The amount of time it takes for the batteries to reach 1.39V, which is where a lot of electronic equipment stop operating, are listed. The Panasonic battery took 6.3 hours to reach that level, while it took 4.5 hours for the Sony battery. The Panasonic battery when used in conjunction with a regulator, according to embodiments of the invention, took 27.9 hours before it stopped providing 1.5V, and the Sony battery when used with a regulator took 32 hours before its stopped providing 1.5V. Thus, with the regulator, it takes 4.5 to 7 times longer before the battery needs to be replaced. Thus, the total number of batteries that need to be manufactured and consequently discarded would be reduced by 4 to 7 times.
Is Fig7 in the patent the batterizer or what they claim to be a typical use curve?
Jay, amazing work!
Have you looked at adding a bypass mode to your booster?
(Does anyone know if the Batteriser has a bypass FET?)

Here's the patent text 'explaining' fig 7:QuoteFIG. 7 shows measurements that illustrate the advantages of the various embodiments. Three popular AA battery brands, Panasonic, Duracell and Sony were chosen for the measurements. Active load circuitry that drew a fixed 50 mA current was placed at the output of these batteries and the voltage of each battery was measured over time. The horizontal access shows time and the vertical access shows the battery voltage. The starting voltage for these fresh batteries was 1.6V. The amount of time it takes for the batteries to reach 1.39V, which is where a lot of electronic equipment stop operating, are listed. [(A)] The Panasonic battery took 6.3 hours to reach that level, while it took 4.5 hours for the Sony battery. [(B)] The Panasonic battery when used in conjunction with a regulator, according to embodiments of the invention, took 27.9 hours before it stopped providing 1.5V, and the Sony battery when used with a regulator took 32 hours before its stopped providing 1.5V.

I've no idea what the horizontal line at 1.8V is supposed represent, but I believe the vertical lines shows where *their* 'Regulator' stops functioning. The 1.39V which they claim "is where a lot of electronic equipment stop operating" isn't shown, and probably the cause of much confusion. Also 1.35V is mentioned in the table underneath but isn't drawn in fig 7 either.
Hello.
I'm a total n00b to simulators.
Anyone knows if I can import your model to QUCS?
Call me an Open Source zealot, but I prefer to use FOSS whenever possible.
I'll try it this week, but I'm totally dumb with simulators and I even need to improve a lot at electronics theory.
we agree with you thatvoltagerun time under load would be different from no load condition, which was the whole point of the Monkey video to demonstrate that batteries are different thanpower suppliesLTspices. The use of abench power supplyLTspice (with no current limit setting) to determine devicecut off voltagerun times is inaccurate. Prior to our video release, the most important battery parameter, its Internal Resistance , was being ignored, because no one discovered Internal Resistance until our Engineerers came along.
Pls stay tuned for our next video explaining our complete lack of understanding of technical details.
