Under what circumstances does the battery need to be replaced?
1 Answers
Car battery replacement situations: 1. The car is harder to start than usual. 2. Headlights dim at idle speed, because the engine's charging power decreases at idle, and the degraded battery has to power the car's electrical equipment, resulting in a significant drop in the power allocated to the headlights. 3. The battery fault warning light is on, and you need to go to a 4S or repair shop for inspection and replacement. 4. Abnormal noise when starting: Due to the weakened discharge capacity of the battery, the starter operates poorly and makes a squeaking sound. 5. Observation port changes: Many maintenance-free batteries have an observation port with a light indicating whether the battery is working well—green means good, black means the battery needs to be replaced. 6. If the battery bulges or leaks, it should be replaced promptly.
