The indicator is designed to alert you to any potential issues with the battery, allowing you to take corrective action before it’s too late.
There are several types of car battery health indicators, including:
- State of Charge (SOC) indicator: This displays the battery’s current state of charge, usually as a percentage.
- Charge Indicator: This shows whether the battery is fully charged, partially charged, or fully discharged.
- Battery Condition Indicator: This provides information about the battery’s overall health, including its age, capacity, and internal resistance.
- Warning Indicator: This alerts you to potential issues with the battery, such as low voltage or high internal resistance.
