What does the red battery indicator light on the dashboard mean?

When the dashboard displays a red battery indicator light, it indicates a fault in the battery system. The possible causes are: 1. Battery aging; 2. Loose battery connections; 3. Generator failure; 4. Engine belt failure; 5. Insufficient voltage; 6. Fuse and relay failure. The maintenance methods for the battery include: 1. Avoid overusing the battery; 2. Regularly clean the positive and negative terminals of the battery; 3. Periodically check the vent holes on the cover of non-maintenance-free batteries to prevent blockage; 4. Avoid low battery water levels; 5. Start the vehicle once a week to charge the battery when parked for extended periods. The functions of the battery are: 1. To supply power to the engine starting system, ignition system, and the vehicle; 2. To power the vehicle's electrical equipment when the engine is off or at low idle; 3. To mitigate impact voltage in the system and protect the vehicle's electronic equipment.
I've been driving for over twenty years, and when the red battery light on the dashboard comes on, it means there's a problem with the car's charging system. Common causes include a faulty alternator or a broken belt, which prevents the battery from charging. The car will soon run out of power and stall. If ignored and driven further, it could lead to minor issues like engine overheating and part damage, or major accidents like steering wheel lock-up. So, as soon as I see this light, I immediately slow down, turn on the hazard lights, find a safe spot to check if the belt is loose, or call a tow truck to take the car to the repair shop to avoid more serious damage. Regularly, I check the charging system and belt condition as a preventive measure to ensure safe driving.
