The short-circuit current of a battery will depend on its voltage, chemistry, size and internal structure. We can usually simplify this to a simple model of an ideal voltage source and an equivalent series resistance. It should be clear from the model that the voltage at the battery terminals will droop with increasing current.

What is a short circuit in a battery? A short circuit occurs when the positive and negative terminals of a battery come into direct contact without any resistance. This creates a pathway for high current flow and can lead to overheating, damaging the battery and potentially causing a fire or explosion.
By short circuit we mean an electrical short circuit, a very low resistance path between the positive and negative sides of the cell or cells. A short circuit can be inside a battery cell or external to a battery cell.

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.
