The lead-acid starting battery of a car is the core of the vehicle's electrical system. Its main task is to provide the starter with an instantaneous and powerful current (usually up to several hundred amperes) to ignite the engine. Once the engine starts, it switches to standby mode, where the generator charges it and supplies power to on-board electrical appliances such as lights and audio systems.

Its interior is mainly composed of a positive plate (lead dioxide), a negative plate (spongy lead), a separator and an electrolyte (dilute sulfuric acid). During discharge, the active material on the plates undergoes a chemical reaction with sulfuric acid to generate electrical energy. During charging, the process proceeds in reverse, and electrical energy is converted into chemical energy for storage.

The most notable features of this type of battery are its powerful starting current (CCA value) and shallow cycle characteristics, meaning it is specifically designed for short-term high-power discharge rather than deep charge and discharge. Frequent deep discharges will greatly damage its lifespan.

Modern passenger cars generally use "maintenance-free" lead-acid batteries, whose electrolyte is sealed and cannot be added. Their service life is usually 2 to 4 years, depending on driving habits, ambient temperature and the number of charge and discharge cycles. When phenomena such as weak starting power and significantly dimming headlights at idle speed occur, it often indicates that the battery needs to be inspected or replaced. As consumables in automobiles, their health conditions are directly related to the reliability of vehicle start-up and electrical safety.
