One of the most noticeable signs a car battery is dying is trouble starting your car.

2. Dim or Flickering Lights: A Clear Indicator of a Dying Battery
If you notice that your headlights or interior lights are dimming, it’s another one of the signs a car battery is dying.

A dying battery may cause electrical systems in your car to malfunction. This could include issues with the radio, air conditioning, or power windows. If you experience electrical failures, it’s one of the signs a car battery is dying and should not be ignored.
4. Corroded Battery Terminals: A Visual Sign of a Dying Battery
If you notice a white, powdery substance around the battery terminals, it’s a sign of corrosion.

5. The Check Engine Light Is On: Another Clue That the Battery Is Dying

As batteries age, their ability to hold a charge diminishes. Typically, car batteries last between three and five years.
