What is the reason for the battery indicator light flashing continuously?

The reasons for the battery indicator light flashing continuously: 1. When starting the engine, the battery indicator light comes on. In this case, it is generally due to the battery's low charge level, triggering the battery warning; 2. If the battery indicator light comes on while driving, it is caused by a malfunction in the car's alternator not generating electricity. This could be due to a broken alternator belt or damaged components in the alternator. The flashing battery light is a reminder that the engine is not generating electricity and does not affect the car's ability to continue driving. At this time, the battery provides all the power to the vehicle, reminding the owner to charge the battery promptly after use. If the light continues to flash after charging, the owner should quickly take the car to a repair shop to check the reason the engine is not generating electricity and resolve the issue to eliminate any potential hazards.
I remember the battery warning light kept flashing the last time I was driving. At first, I didn't take it seriously, but then the car suddenly stalled on the highway, which could have caused a major incident. After inspection, it turned out to be either a loose and aged alternator belt causing unstable charging, corroded and rusty battery terminals leading to poor contact, or worn-out carbon brushes inside the alternator failing to provide stable power. The flashing light is a warning that there's an issue with the charging system, possibly indicating unstable voltage. It's best to pull over immediately and manually check the tightness of the battery terminals, but don't push through and keep driving—find a repair shop for diagnosis as soon as possible. Similar issues often arise from lack of maintenance. Now, I check the alternator and battery condition every six months, replacing belts or cleaning terminals to prevent corrosion.
