Can a car battery still be used if the liquid has leaked out?

[MacCamille]

Lead-acid batteries contain an electrolyte solution composed of sulfuric acid and distilled water in a specific ratio, which is corrosive. If the battery leaks a small amount of liquid, it can still be used after cleaning, but the leak must be repaired promptly. If the battery leaks excessively, it cannot be used and must be replaced. Signs of a failing car battery include: 1. Difficulty starting the car: If the car suddenly becomes difficult to start without other factors, it may be a sign that the battery is about to fail. 2. Dimming lights during idle: For example, when stopped at a red light or temporarily parked, the headlights may suddenly dim. This is because the engine's charging power decreases during idle. 3. Battery warning light illuminates: When the battery warning light comes on, it is a reminder for the owner to have the battery inspected and repaired at a service center. 4. Normal driving but occasional complete power loss after parking and restarting: This occurs because the battery's lifespan is nearing its end, resulting in insufficient starting current, increased oxidation at the battery terminals, and a complete power loss issue.
