The Most Common Causes of Car Battery Failure

Understanding the common causes of car battery failure can help you take preventative measures and minimize the risk of unexpected breakdowns. Let’s skip the part with what a battery is because you probably know by now, taking into account you are reading this article.

Car batteries have a limited lifespan, typically ranging from three to five years. Over time, the battery's ability to hold a charge diminishes, leading to eventual failure. Regularly check the age of your battery and consider a replacement if it is nearing the end of its expected lifespan.

What Is The Most Common Cause?

Extreme temperatures, whether excessively hot or cold, can strain the battery and accelerate its deterioration. In cold weather, the battery's capacity may decrease, making it more difficult to start the engine. High temperatures can cause fluid evaporation and internal damage to the battery. Take precautions in extreme weather conditions and consider using insulation or battery blankets to protect against temperature extremes.

What Are Some Other Reasons For This To Happen?

Neglecting battery maintenance can contribute to its premature failure. Regularly inspect the battery terminals for corrosion and clean them if necessary. Ensure the connections are tight and secure. Additionally, check the battery's water level in non-sealed batteries and top it up if needed with distilled water.

Electrical problems in your vehicle can put a strain on the battery. Faulty alternators, voltage regulators, or wiring issues can cause the battery to drain or not charge properly. If you notice persistent electrical issues, have them diagnosed and repaired promptly to prevent battery failure.

Parasitic drains refer to electrical components that draw power from the battery even when the vehicle is not in use. Common culprits include interior lights, trunk lights, or malfunctioning devices. If you notice your battery frequently going dead, it may be due to a parasitic drain. Talk with your local mechanic or consult with us by calling the number below!

Accidentally leaving lights, radios, or other accessories on when the engine is not running can quickly drain the battery. Always double-check that all lights and accessories are turned off before exiting the vehicle.

Finally, if your vehicle primarily takes short trips or sits idle for extended periods, the battery may not have sufficient time to recharge fully. Regularly driving your vehicle for a longer duration.
