I believe what your referring to is the cutoff protection in the cell itself. This can be tested.

When I use the micro USB rechargeables, I think mine are a different brand, I just change the erx batteries every 15 hours.

The way it "draws less when voltage is lower", less what? I didn't know there was an argument. That shows how little I know.

And different cells with different internal resistance figures and probably different temperatures of the device and the cells and maybe different amounts of grunge on the rechargeable cells? And probably not, I'm just speculating here, a very smart charger that can see what's happening in the cells and report that info to the user.

A couple of things to consider. I don’t think any of us are running Energizer lithiums until their dead, so, users vary, but maybe 20 percent of the capacity of an energizer lithium is unusable. On the micro USB rechargeable, you can change as often as you like and you're never "throwing away" capacity like we do with the Energizer lithiums. And, the current doesn't go up on the rechargeable lithiums because they start at about 1.5 volts and once fully discharged, they are still about 1.5 volts. Thank you.

Larry, Good stuff to know, thanks for the answer. .9 volts, wow, what is the amperage at that point?

Larry, haha, I looked it up, I see the battery eliminater, now I see what you were doing. What is your theory on what happened in the referenced case? Only one battery reported to have been utilized. I still stand by my position that this scheme is different than what is usual or expected. Is there any other transmitter manufacturer that uses this scheme? Thank you, Martin

Why would I have a hard time believing that? Because that is an odd design.

This would be easy to identify, try checking if it will run with a cell in either of the 2 positions, 1 cell at a time, if it does run, then yes, it is in parallel, which I have a hard time believing.

Hi Johnny, are you saying that somehow, the 2 batteries were wired in series, and somehow the unit managed to not use the one cell, that was in series? Hey SMQV people weigh in here, are the 2 cells in parallel? And not series? Thank you.

Thank you for your input, as I was simply addressing someone who had indicated that they were not happy with the voltage dropping to 1.2 volts. I am happy to see you agreeing with me about these batteries maintaining a higher voltage. The user of the device who did not care about the voltage dropping to 1.2 on the older style batteries, Nimh, Nicad, etc, would not have this issue on the newer cells. And of course when the voltage drops, the amperage goes up, absent a circuit that subsequently lowers the wattage as the voltage of the cell drops, then heat also goes up. That is why I don't use a main battery system of 12 volts on Nova, because of higher amperage. The other reason being the minimum voltage level of the Nova is reached before the discharge level of the battery pack is reached, thereby leaving unusable power in the battery pack. As far as "Mumbai" , I was simply doing math based on the science.

I didn't mention anything about equipment design. I don't know the "Mumbai jumbo" you refer to and I'm not sure you understand how these cells function. Think of it this way, if there was a piece of equipment, let's call it the Throwtrap 5000, and this device ran on 1.5 volts minimum voltage, at 1.49 volts there is no longer enough voltage to power the 5000. This is what we are discussing here. With that understanding, how long does the cell in question maintain 1.5 volts?

Not sure what your question is.

I addressed someone who didn't seem to care for the voltage running at 1.2 volts. I guess the way for you to think about this equation: If you were to measure these 2 different types of cells at 1.5 volts or higher, which cell would provide a longer run time at or above 1.5 volts? There is the answer.

You asked "where do I get this?" and then talk about one being "better". I didn't say one was better or worse because of this, I made the statement that the cells at discussion here would be at 1.5 volts longer than Energizer lithium, and since a depleted Energizer Lithium has 1.5 volts for less time than the battery than the ones in this discussion, that is where I "get this".
