The battery provides the electrical charge your car needs to start, and the alternator works to recharge it as you drive. When the battery starts to fail, your vehicle will have trouble functioning properly. Learn to recognize when your car needs battery replacement so you aren’t left stranded if it dies. 

3 Symptoms of a Failing Battery

1. Slow Engine Starts

The components inside your car battery that generate an electrical charge can corrode and fail, resulting in less energy available. When your car battery starts to die, it may take longer for your car to start when you turn the ignition. 

2. Dim Lighting 

The battery also fuels the electronic components of your car, including interior lighting, headlights, and even the sound system. If the battery weakens, you may notice dimming lights, especially as more devices are used inside the car. For instance, the dashboard lights or headlights may dim when you charge your phone using the console. 

If you notice issues with dim lights inside your car, have a mechanic test the battery. After attaching electrodes to your system, they can determine if a battery replacement is necessary. 

3. Visible Corrosion

If you notice a white, powdery substance around the car battery terminals, the unit may be releasing gases as it struggles to provide power, which can lead to voltage issues. Corrosion can also make it difficult to jump-start the car since it can interfere with electrical connectivity. Check the appearance of the car battery and connectors whenever you top off your fluids, and get a replacement if you notice visible problems.
