Recognizing a Failing Car Battery: Early Warning Signs

Several subtle signs can indicate your car battery is starting to fail. These early warnings can be easily overlooked, but paying attention to them can prevent future headaches. One of the first signs of a battery going bad is a slow engine crank. If your engine takes longer than usual to turn over, it could be a sign that the battery is struggling to provide enough power.

Dim headlights, especially when idling, are another common indicator. The battery struggles to maintain power to all electrical components when the engine isn’t running at higher RPMs. Similarly, flickering interior lights or dimming dashboard lights can also point to a weakening battery.

More Obvious Signs of a Battery Going Bad

As the battery deteriorates further, the signs become more pronounced. Clicking sounds when you turn the key, but the engine doesn’t start, indicate the battery doesn’t have enough power to engage the starter motor. This is often accompanied by dimming or flickering dashboard lights.

A swollen battery case is a serious sign and requires immediate attention. This can be caused by excessive heat or internal malfunction, potentially leading to leaks or even explosions. Never attempt to jump-start a car with a swollen battery.
