Should the car battery be replaced when it's around 60%?

[LeCaleb]

Car battery around 60% does not need to be replaced. Under normal circumstances, when the car battery shows around 50%, as long as the internal resistance is small enough to start the engine, it can temporarily not be replaced. Below are the specific details: Car battery lifespan: The designed lifespan of a car battery is 27 months. Generally, family cars are more power-efficient, and new car batteries mostly last 3-4 years. However, after the first replacement, they usually need to be replaced again in about 2 years. Methods to determine if a car battery needs replacement: Carefully observe whether there are obvious signs of bulging or deformation on both sides of the car battery. Check if there are white or green powdery substances around the battery terminals. These are oxides of the battery. High-quality or new batteries generally do not easily develop such oxides. Once they appear, it means the battery's performance has started to deteriorate.
