What Happens If a Battery is Short-Circuited? (What is Short Circuit Protection in a Battery?)
A battery short circuit is a condition where the electrical current in the battery bypasses the normal flow of electrons through the circuit. This can happen if the positive and negative terminals of the battery are accidentally touched together, or if a wire that is connected to the battery becomes frayed or broken.
