What Causes a Car Battery to Die?

[McRiley]

The reasons for a car battery dying are: 1. Prolonged use of onboard electrical appliances after the vehicle is turned off, such as running the air conditioner, headlights, or audio system while the engine is off; 2. Long-term parking of the vehicle, as the battery self-discharges and gradually loses power; 3. Generator failure preventing it from producing electricity, leading to the battery eventually dying; 4. Natural aging of the battery. Maintenance methods for the battery include: 1. Charging the battery promptly when the ammeter indicates low power; 2. Adjusting the electrolyte density according to standards based on different regions and seasons; 3. Adding distilled water or a specialized replenishing fluid when the electrolyte is low; 4. Limiting the total duration of each engine start to no more than 5 seconds; 5. Starting the car periodically if the battery is unused for a long time; 6. Regularly checking if the small holes on the battery cover are ventilated; 7. Inspecting the battery's positive and negative terminals for oxidation; 8. Checking all parts of the circuit for aging or short circuits.
