What Are the Reasons for the Reduced Lifespan of a Car Battery?

[VonCaleb]

The reasons for the reduced lifespan of a car battery are: 1. Severe sulfation of the plates; 2. Severe water loss; 3. Short circuit in a single cell; 4. Excessive impurities in a single cell leading to rapid self-discharge. The functions of the battery are: 1. To supply power to the starting system, ignition system, and electronic fuel injection system; 2. To provide power to the car's electrical equipment; 3. To participate in power supply when the electrical demand exceeds the generator's supply capacity; 4. To protect the electronic equipment in the car. The maintenance methods for the battery are: 1. Start the car regularly to charge the battery; 2. Add distilled water or a special replenishing fluid when the electrolyte is low; 3. Frequently check whether the small holes on the battery cover are ventilated during daily driving; 4. Check whether the positive and negative terminals of the battery are oxidized; 5. Check for any aging or short circuits in the circuit parts; 6. Turn off electrical equipment when leaving the car.
