Sorry, I must have imagined that. Anyway, my point was that the reality is too complicated to easily assign a number to - that they don't even try supports that. Duracell's datasheets don't even have a single number, just a bunch of line graphs. > > You have to know your devices to know if the voltage difference > > between different battery types (Which ranges from 1.2 to 1.7 for > > nominal-1.5 AAA/AA/C/D cells, and may be lower under load) is > > significant or not, and in what direction. > > Well, your amp hours will be shittier with a lower voltage. Define "shittier". An incandescent flashlight (which consumes less power at lower voltage) will last longer, but won't be as bright. If it's still acceptably bright, that's not worse. > That's why > reporting joules would be more honest. And *my* point is that the number of joules depends on how the battery is used. And different types of batteries are optimized for different applications. -- https://mail.python.org/mailman/listinfo/python-list
