Signs of a Failing Car Battery
A failing car battery can exhibit a range of symptoms, from minor issues to catastrophic failures. Here are some common signs to look out for:

If your headlights are dimmer than usual or flickering, it may indicate a battery issue. This is because the battery is struggling to provide enough power to the electrical system.
