Turn Off the AC or Turn Off the Engine First?

[McKarter]

You should turn off the AC before turning off the engine. Normally, after parking, most car owners turn off the engine first and then the AC, but this is incorrect. If done this way, the next time the car starts, the engine will start with the AC running, which undoubtedly increases the engine's load. Besides increasing fuel consumption, it also damages the engine itself. Here are some precautions for using a car battery: 1. Remember to turn off the lights: For example, forgetting to turn off the lights during the day, especially the headlights. Some beginners may play with the car lights during the day and forget to turn them off after shutting down the engine. Over time, the battery will be drained. Similarly, listening to music or using the AC when the car is not running will also drain the battery over time. 2. Pay attention to maintenance: To prevent the car battery from running out of power, proper maintenance is essential. First, avoid frequently starting the car. A car has its lifespan, and constant starting and stopping will cause wear and tear. If the car doesn't start on the first try, wait a moment before trying again. Repeated attempts to start the car put a lot of stress on it, increase discharge, and gradually reduce the battery's lifespan.
