I'm a bit confused by the physics in this patch. The internal resistance of a battery is not a constant in its life cycle, this varies over the age of the battery, and the reason I thing is chemical residuals accumulating on the anode and cathode inside the battery and the energy storage medium aging. (Plus/minus my ignorance about how batteries actually work.) AFAIK the fact that the internal resistance varies is of high importance for people developing algorithms of battery capacity and longevity. Such that some (hardware) capacity monitors go to great lengths to measure with high precision the current internal resistance of the battery for their algorithms. Sorry for making things more complex, but should it be named "factory-internal-resistance-micro-ohms" or "typical-internal-resistance-micro-ohms"? Yours, Linus Walleij
