What does it mean when the battery plates of a car are damaged?

The battery plates are already damaged. If the battery plates of a car are damaged, the battery must be replaced. The two electrodes of a chemical power source are composed of active materials and current collectors for support and conduction, usually in the form of porous sheets. During manufacturing, the active materials are often not directly added to the current collectors but are instead made into a paste-like form and applied to the grid, or the raw materials are filled into glass fiber tubes before undergoing a formation process to generate the active materials. Additional Information: Note 1: It is recommended that users regularly check whether the small holes on the battery cover are ventilated. If these small holes are blocked, the generated hydrogen and oxygen cannot escape, and the expansion of the electrolyte may rupture the battery casing, affecting the battery's lifespan. Also, regularly inspect whether the positive and negative terminal connections are loose, and tighten them promptly if necessary. Note 2: If the water level is found to be below the lower mark, distilled water must be added. If distilled water is not immediately available, filtered tap water can be used as an emergency measure. Do not add too much water; the standard is to fill it to the midpoint between the upper and lower marks.
Automotive battery plate damage refers to the failure of the internal metal plates within the battery, a common issue encountered during daily driving. Having driven several older cars, I've noticed that battery plates are typically made of lead and are responsible for storing and releasing electrical energy. If they become damaged—due to sulfation or corrosion, for example—the battery can no longer hold a charge, with obvious symptoms: the engine struggles to start or fails to ignite entirely. Causes vary, including overcharging (which can warp the plates), deep discharge without timely recharging, or accelerated aging due to high summer temperatures. Once, my car had this issue during winter—it took forever to start, and a voltmeter later confirmed the problem. For prevention, regularly check the battery's charge status during maintenance and avoid leaving the car unused for extended periods. The repair solution is usually a direct battery replacement—don't cut corners, as a failing battery might stall unexpectedly. Battery lifespan is typically 3-5 years; replacing it early saves money and ensures safety.
