What Causes a Car Battery to Suddenly Die in Winter?

[LaAlice]

Reasons for a car battery suddenly dying in winter include: 1. The car has been parked for a long time, causing the battery to lose power; 2. The battery has reached the end of its service life; 3. Engine damage; 4. Insufficient battery electrolyte or leakage; 5. A blown fuse causing the battery to lose power. Battery maintenance methods include: 1. Start the car periodically to charge the battery; 2. Avoid parking the car in an open parking lot for extended periods. If long-term parking is necessary, remove the battery to prevent freezing damage; 3. Charge the battery promptly when the ammeter shows insufficient power; 4. In winter, car engines are harder to start. Each attempt to start the engine should not exceed 5 seconds, with at least 15 seconds between attempts; 5. Clean the battery terminals regularly and apply special grease to protect the wiring harness; 6. Avoid using car electronics after turning off the engine. Using the battery alone when the engine is not generating power can cause damage.
