[StLondyn]

The red battery warning light in a car is caused by: 1. Failure to turn off electrical appliances in the car when getting off, resulting in the battery being completely drained; 2. Problems with the generator not producing electricity or short circuits in the car's wiring, causing severe battery drain; 3. The battery itself being severely sulfated, aged, internally broken, or short-circuited. The functions of a car battery are to store and supply electricity. Its maintenance methods include: 1. Avoid parking the car in an open-air parking lot for extended periods; 2. Avoid multiple uninterrupted starts; 3. Regularly check the battery's accessories and connecting circuits; 4. Avoid using car electrical appliances after the engine is turned off.
