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.
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 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.
A battery can supply a current as high as its capacity rating. For example, a 1,000 mAh (1 Ah) battery can theoretically supply 1 A for one hour or 2 A for half an hour. The amount of current that a battery actually supplies depends on how quickly the device uses up the charge. What Factors Affect How Much Current a Battery Can Supply?
Assuming you have a 12V battery that is in good condition, it can supply up to 30 amps of current. The amount of current that a battery can provide depends on its size and capacity. A larger battery will be able to provide more current than a smaller one. How Batteries are Rated?
For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current and gets a bit lower for moderately elevated temperature (say, ~50C). The initial short-circuit current for such a battery is ~1 Ampere.
How much current a battery can supply is limited by the internal resistance of the battery. The higher the internal resistance, the lower the maximum current that can be supplied. For example, a lead acid battery has …
