Writer's picture: Marble Falls Auto CenterMarble Falls Auto Center

Your car’s battery is a vital component that powers your vehicle’s electrical system, from starting the engine to running essential systems like lights and the radio. However, like all parts of your car, the battery doesn’t last forever. A dying battery can cause a range of issues, from difficulty starting your car to complete electrical failure. In this blog post, we’ll discuss how to know if your car’s battery is dying and what steps you can take to avoid being stranded. At Marble Falls Auto Center, we offer comprehensive battery testing and replacement services to ensure your vehicle remains reliable.


1. Slow Engine Crank

One of the first signs that your car’s battery might be dying is a slow engine crank. When you turn the ignition, the engine may take longer to start than usual, or it might make a sluggish, struggling sound. This is because a weakened battery cannot provide enough power to the starter motor to quickly turn the engine over. If you notice that your engine cranks slowly, it’s time to have your battery checked by a professional.

At Marble Falls Auto Center, we can test your battery to determine if it’s still in good condition or if it’s time for a replacement.


2. Dimming Headlights or Interior Lights

If you notice that your headlights or interior lights dim when you start the car or when you’re using electrical accessories, it could be a sign of a weak or dying battery. As the battery loses power, it struggles to supply the necessary voltage to your car’s electrical system, causing the lights to appear dimmer than usual. This issue can become more noticeable at night when the lights are on for extended periods.

If you’re experiencing dimming lights, it’s important to have your battery checked immediately. At Marble Falls Auto Center, our expert technicians can diagnose your battery’s health and ensure that your car is operating at peak performance.


3. Electrical System Malfunctions

A failing battery can cause other electrical system malfunctions. If you notice that your car’s power windows, air conditioning, or radio are acting up, it could be due to a weak battery. Electrical systems rely on the battery to provide a consistent flow of power, and if the battery can’t keep up, you may experience intermittent issues with these components.

If you experience electrical issues in your car, it’s a good idea to have your battery tested and the charging system inspected. Marble Falls Auto Center offers full-service battery testing and diagnostics to ensure your car’s electrical system is functioning properly.


4. Check Engine or Battery Warning Light

Modern vehicles are equipped with warning lights that alert you to potential issues with your car. If your car’s dashboard displays a "Check Engine" light or a battery warning light, it could indicate a problem with your battery or charging system. A battery warning light may indicate that the battery isn’t charging properly, while the check engine light could point to a range of issues, including a failing battery.

If you see either of these warning lights, it's important to schedule a diagnostic check at Marble Falls Auto Center to determine the root cause of the issue and address it before it leads to further complications.


5. Swollen or Leaking Battery

If you notice any swelling or leaks around your car’s battery, this is a clear sign of a serious issue. A swollen battery typically occurs due to excessive heat or overcharging, and it can lead to leaking fluids that are harmful to your vehicle. Leaking battery acid can also cause damage to the battery terminals and surrounding components.

If you notice any physical signs of battery damage, such as swelling or leakage, it’s crucial to replace the battery immediately. Marble Falls Auto Center can inspect your battery for damage and replace it with a new one to keep your vehicle running smoothly.

6. Age of the Battery

Car batteries typically last between 3 to 5 years, depending on factors like usage, climate, and the quality of the battery. If your battery is approaching or has exceeded its expected lifespan, it’s more likely to fail soon. Even if you haven’t noticed any symptoms of a dying battery, it’s a good idea to replace it once it reaches the end of its life.

At Marble Falls Auto Center, we can help you determine if your battery is nearing the end of its lifespan and recommend the best course of action to ensure your car stays reliable.


7. Foul Smell or Corrosion Around the Battery Terminals

If you smell a rotten egg-like odor near your car’s battery, this could be a sign of a leaking battery. The smell is caused by sulfuric acid vapor, which can be harmful if inhaled. Additionally, if you notice white, powdery corrosion around the battery terminals, it may indicate that the battery is leaking or overcharging.

Both of these issues require immediate attention to prevent further damage to your vehicle. Marble Falls Auto Center offers battery inspections to identify and address any potential issues before they cause serious problems.


8. The Car is More Than 5 Years Old

If your car is more than 5 years old and you’ve never replaced the battery, it’s a good idea to have it tested, even if you haven’t noticed any of the other symptoms. Over time, the battery’s performance naturally degrades, and a battery that is more than five years old is more likely to fail unexpectedly.
