The charging voltage for a car battery should be between 14v and 15v, with the optimal charging current being 10% of its capacity. Here are some car battery maintenance tips: 1. Turn off all lights before shutting down the engine: Some older models do not support automatic power-off after the engine is turned off, so you need to manually turn off the headlights and interior reading lights before shutting down. If you need to find something in the car or require lighting, you can use a mobile phone or flashlight for illumination. 2. Avoid leaving the vehicle parked for extended periods: The battery installed in the car will self-discharge over time when left unused. Many car owners find it difficult to start the car or even discover a completely dead battery after returning from a business trip or vacation. Therefore, it is best to drive the car at least once a week, with a trip duration of at least 20 minutes, to allow the battery to charge while driving. 3. Close all windows before shutting down the engine: The switches for the car windows and sunroof are powered by the battery, so it is best to close all windows before turning off the engine, rather than after. Avoid using the long-press lock button method to close the windows after leaving the car.

What are the consequences of excessively low engine temperature?

Excessively low engine temperature can lead to the following consequences: 1. Reduced cylinder air intake and abnormal combustion, resulting in decreased engine power; 2. Accelerated wear of engine components due to poor lubrication, potentially causing seizure or damage; 3. Unvaporized fuel washing over cylinder surfaces, destroying the lubricating oil film and increasing component wear; 4. Difficulty in engine starting. The causes of excessively low engine temperature include: 1. Extremely low ambient temperature causing engine fluid to congeal; 2. Malfunctioning thermostat or fan leading to excessive cooling; 3. Stuck thermostat not fully opening. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, and electric motors.
