Will the car battery run out of power in hot weather?

[ONaomi]

Hot weather will not cause a car battery to run out of power, as vehicles do not lose power due to temperature. Impact of cold weather on batteries: Generally, the optimal operating temperature for a car battery is around 25 degrees Celsius. For every 1-degree drop in temperature, the battery's available capacity decreases by approximately 0.8%. The capacity returns to normal when temperatures rise again. Therefore, in cold weather, especially in northern regions where temperatures often drop below freezing (sometimes even dozens of degrees below zero), the battery's available capacity decreases significantly, and its performance becomes more fragile. Car battery lifespan: The typical lifespan of a car battery is about 2-3 years. With proper use and maintenance, it can last up to 4 years without damage.
