Why does the battery indicator light occasionally come on?

[HaleyLynn]

The reasons why the battery indicator light occasionally comes on are: 1. The belt or tensioner is too loose; 2. The generator carbon brush is worn; 3. The generator voltage regulator is faulty; 4. The battery terminals are not tightened; 5. The battery sensor is faulty. The battery, also known as a storage battery, is a type of cell that works by converting chemical energy into electrical energy. Batteries are categorized into ordinary batteries, dry-charged batteries, and maintenance-free batteries. The maintenance methods for batteries are: 1. Start the car regularly to charge the battery; 2. When the electrolyte is low, replenish it with distilled water or a special replenishing fluid; 3. Frequently check whether the small holes on the battery cover are ventilated during daily driving; 4. Check the positive and negative terminals for signs of oxidation; 5. Inspect all parts of the circuit for aging or short circuits; 6. Turn off electrical equipment when leaving the car.
