Short circuiting a battery means excessive current follows an unintended path, due to an abnormal connection with little or no impedance. An uncontrolled surge of energy can damage the circuit, and result in. . A short circuit occurs when electrical current flows through an unintended path with little or no resistance, often causing excessive current flow, heat, and possible damage. This can cause an explosion and release toxic fumes. This can lead to: A battery short circuit protection is a built-in safety mechanism that instantly cuts off power when a short is detected. At best, the battery will be run down quickly.
