Will turning on the air conditioning without starting the car damage the battery?
1 Answers
Turning on the air conditioning without starting the car can indeed damage the battery. Here are the relevant details: 1. Using the air conditioning with only power on but engine off: When you turn on the air conditioning without starting the engine, it will not produce any cooling or heating effect. The air conditioning compressor is driven by the engine to generate cooling. In this scenario, using the air conditioning will only rapidly drain the car's battery, thereby harming it. 2. Precautions: Try to avoid using the air conditioning when driving at low speeds. During traffic jams, do not increase the engine speed to enhance air conditioning performance, as this can adversely affect the lifespan of both the engine and the air conditioning compressor.
