If you "forget about" internal resistance, then the maximum current is infinite. An "ideal" component, non-existent in the real world, can provide mathematically "pure" infinite or zero amounts of resistance, voltage, current, and all the rest. Different battery compositions will have different amounts of real-world "impure" limitations.
So, yes. Batteries have a max current drain (given by design and physical/chemical limitations) and yes the storage rating (being Ah, Wh or Joules) changes depending on battery design and load applied, and yes Wh is a better way to compare batteries because it takes voltage in account.
So for any sensible lifespan you are looking at a useful maximum of around 30mA. Battery capacity is usually a measure of AH capacity and is based on physical size rather than rated voltage. In essence a large battery has greater capacity than a smaller one of the same voltage and hence may be considered as capable of greater current capability.
Max discharge current for lipo's depend on the application. For example, quadcopter lipo's generally tend to have very high discharge currents (like 20-25C) How can i calculate the maximum current a battery can provide if the only information i have is: 7.2 V / 11.5 Wh / 1600 mAh.
Batteries have not only a voltage rating, but an "amp" capacity rating. Dry cells, such as common flashlight batteries (or standard 9-volt batteries you are referring to) have a very low amp capacity. Wet cells, such as a 12-volt lead-acid car battery have very high amp capacities.
1) The battery has a maximum power it can provide. For example, if this power is P = 100 W, then since P = RI^2 the current will be I = (P/R)^0.5 = 31.6 amps and the voltage V = RI = 3.16 V. 2) The battery has a maximum current it can provide. For example, if this current is I = 5 A, then V = RI = 0.5 V.
A typical CR2032 can source much more current than 5 mA. You could pull 100mA from it, for under an hour, with some caveats about it''s high ESR. The nominal current …
I think what would be a lot more useful is the max current that can be provided at voltages of (say) 9v, 8,5v and 8.0v. After all, it is a 9v battery and output at 0.6v is likely to be irrelevant for any application that specifies a …
