The car battery is a crucial component of any vehicle as it provides the necessary power to start the engine and supplies electricity to the car’s electrical system. When a car battery fails, it can be highly frustrating, as it prevents the car from starting and may leave you stranded.

If you’re curious about the reasons behind car battery failure, you’ve come to the right place. At Treasure Valley Auto Care, we will explore the causes of car battery failure. Continue reading below to learn valuable information that can help you prevent your car battery from failing.

Here are the common reasons why car batteries fail.

Life Span of Battery 

Car batteries typically have a limited lifespan, usually lasting around 3-5 years. The actual duration depends on factors such as usage frequency and exposure to various elements, which can contribute to the battery losing its ability to hold a charge and functioning properly.

As the car battery ages, it may no longer perform effectively, necessitating a replacement. If you’re unsure about which battery is suitable for your car, seeking assistance from a professional technician at a car shop is recommended.

Not Properly Maintained 

Treasure Valley Auto Care excels in all aspects of auto repair.

It is essential to regularly clean the battery terminals to prevent the formation of rust and corrosion, as they are prone to these issues. Additionally, ensuring that the terminals are properly tightened is crucial, as loose connections can also lead to car battery failure.

Corroded battery terminals can impede the flow of electricity from the battery to other parts of the car, resulting in difficulties such as engine starting problems or inadequate power supply to the car’s electrical systems. Similarly, improperly fastened battery terminals can result in poor connections and similar issues.

Extremely High or Extremely Low Temperature 

Are you residing in an area with extreme temperatures? If so, it’s important to be aware of how it can impact your car’s battery and potentially reduce its lifespan.

In extremely cold weather, the battery may struggle to generate sufficient power to start the engine due to the chemical reactions within the battery being impeded.

This can lead to a quicker discharge and potential battery failure. Conversely, extremely hot temperatures can cause the battery to overheat, accelerating the evaporation of battery fluid and diminishing its ability to hold a charge.

Electrical Issues 

A faulty alternator or other electrical issues can contribute to battery drain and eventual failure. The alternator’s role is to recharge the battery while the engine is running.

If it malfunctions, the battery may lose its charge faster than it can be replenished, resulting in a shortened battery lifespan and eventual failure. Additionally, a short circuit or malfunction within the battery itself can cause accelerated drainage and eventual failure.

Frequently Discharged Battery

Frequent discharging of the car battery without proper recharging can cause irreversible damage. Discharging the battery degrades its internal structure, leading to a reduced lifespan.

Similarly, if the car battery is rarely used and doesn’t have enough opportunities to fully recharge between uses, it can lead to long-term damage and eventual failure of the battery. It is important to ensure the battery is properly charged and maintained to avoid premature failure.

Physical Issues 

Make informed decisions with our comprehensive pre-purchase inspections.

Damaging the car battery by dropping it or puncturing it can result in failure. Dropping the battery from a significant height can cause internal component damage and fluid leakage, ultimately leading to battery failure.

Similarly, if the battery is punctured or cracked, it can result in the loss of battery fluid and eventual failure. It is crucial to handle and store the battery with care to avoid such damage.

Loose or Damaged Connections 

Loose connections in the car battery can negatively impact its performance and hinder the recharging process, eventually leading to battery failure. When connections are loose, proper electrical contact may not be established, resulting in difficulties starting the engine or powering the car’s electrical systems.

Damaged connections can also cause short circuits and other electrical issues that contribute to battery failure. It is important to ensure that the connections are secure and free from damage to maintain optimal battery function.

Incorrect Size 

When purchasing a new car battery, it is crucial to ensure that you select the right size to avoid potential problems and battery failure. The vehicle manufacturer specifies the recommended size and type of battery that should be used.

Choosing a battery that is too small may result in insufficient power to start the engine or power the electrical systems effectively. Conversely, selecting a battery that is too big may not fit properly in the battery compartment, leading to inadequate securement and potential complications.

It is important to adhere to the manufacturer’s guidelines to ensure proper battery performance.

Irregular Use 

Treasure Valley Auto Care: your destination for engine repair excellence.

Many car owners mistakenly believe that when their car is turned off, no energy is being consumed from the battery. However, various components of the car, such as the alarm, locks, and keyless functions, still require electricity that is supplied by the battery.

This continuous power drain can lead to battery discharge over time. It is not uncommon for cars that are left unused in a garage for several weeks, especially during winter or with older batteries, to experience difficulty starting.

To prevent battery discharge, it is recommended to drive the car at least once a week for a minimum of 10 minutes. This regular usage helps keep the battery charged and in good condition.

Short Trips 

When you frequently use your car for short trips, the battery may not have enough time to fully recharge. Additionally, during winter months, using features like rear windows and heated seats can further drain the battery.

To ensure proper battery recharging, it is advisable to take the car on a long-distance trip at least once a month. This allows the alternator to recharge the battery effectively and maintain its optimal performance.

Age of the Car 

Is the car old? This can decrease the battery power due to corrosion that can affect the battery’s ability to properly recharge. You must test the battery regularly to check its health and if it is functioning properly.
