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.

How to Determine if a Battery is Short-circuited

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.
