What is a battery short circuit?

A battery short circuit occurs when there is a low-resistance or no-resistance path between the battery’s positive and negative terminals, leading to excessive current flow. The short circuit current in a battery can vary widely depending on the battery type, capacity, and internal resistance. It can range from tens to hundreds of amperes.
