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?
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.
(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
The higher the internal resistance, the lower the maximum current that can be supplied. For example, a lead acid battery has an internal resistance of about 0.01 ohms and can supply a maximum current of 1000 amps. A Lithium-ion battery has an internal resistance of about 0.001 ohms and can supply a maximum current of 10,000 amps.
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?
