[JeffreyDella]

Methods to keep a car battery warm in winter are: 1. Remove the battery and place it in a warm indoor location; 2. Cover it with a cold-proof blanket; 3. Start the car frequently. The functions of a car battery are: 1. When starting the engine, the battery supplies power to the starting system, ignition system, and electronic fuel injection system; 2. When the engine is stopped or idling at low speed, it provides power to the car's electrical equipment; 3. When the generator's output is insufficient, it can assist in supplying power to the electrical equipment. Maintenance methods for a car battery include: 1. Start the car regularly to charge the battery; 2. When the electrolyte is low, replenish it with distilled water or a specialized replenishing fluid; 3. During daily driving, frequently check whether the small holes on the battery cover are ventilated; 4. Check for signs of oxidation on the positive and negative terminals of the battery; 5. Inspect all parts of the circuit for signs of aging or short circuits; 6. Turn off all electrical equipment when leaving the car.
