What are the reasons for the battery light on the dashboard to illuminate?

[LeHarper]

The reasons for the red battery light on the dashboard are as follows: 1. Low battery charge: If the car is left unused for a long time, the battery's power will gradually drain, leading to insufficient charge. In this case, the car's dashboard will display a red warning symbol to remind the owner to recharge the battery. 2. Battery damage: If the car battery experiences leakage, swelling, or damage during use, a warning symbol will appear on the dashboard, prompting the owner to check the vehicle's battery. 3. Battery wiring issues: If the vehicle's wiring is damaged, short-circuited, or has loose connections causing poor contact, the battery cannot supply power normally, which will also trigger a red warning symbol, reminding the owner to troubleshoot the issue.
