If you’re looking for a new or used Toyota then visit us today at East Coast Toyota, and if your Toyota needs service then stop by the East Coast Toyota Service Center.

Batteries are one of the most important components of your vehicle. They are the energy source your engine relies on to start combustion. They also power your lights and other electrical components on your vehicle. Ensuring your battery terminals are both clean and tight is crucial for optimal performance.

While car batteries do not last forever, you can expect most quality ones to be reliable for many years. If you find that your car batteries are dying faster than expected, there is a reason why. The key is finding out what it is. A malfunctioning charging system is something that can also lead to premature battery failure.

The information below lays out the primary cause of your car battery dying too soon. Keep reading to find out how to identify these and avoid situations where your car will not start. It’s important to note that a dead battery can sometimes be caused by leaving your car parked for too long without use.

1. Faulty Alternator

One of the main reasons for a car battery dying too soon is a defective alternator. This is the component that uses energy from the motor to recharge the battery when the car is running. If an alternator is not working, your battery will drain but have no way of regaining power. A bad alternator can lead to situations where your car battery keeps dying.

One of the most common causes of alternator problems is a diode going out. Electricity flows through these (there are usually several in an alternator), converting it to a current the battery can use. Replacing them is much simpler and cheaper than buying a brand-new alternator.

2. Extreme Temperatures

Severe temperatures can affect battery performance. Freezing slows down the electrons inside the battery, which can impact both the speed of a battery’s charge and its ability to charge. Extremely hot temperatures can also cause the battery fluid to evaporate, reducing its ability to stay charged.

Freezing temps are more of an issue than hot ones, but extreme heat can affect battery performance as well. Higher temperatures can cause electrolyte evaporation, which slows charging and can even damage battery components.

3. Corrosion

Corrosion is a common culprit for battery issues. This happens when volatile chemicals or gases escape and come into contact with conductive metal on the connectors. This hinders the battery’s ability to send power to the starter and can even be dangerous if it comes into contact with your skin.

Major corrosion may be a sign of battery damage. You should consider repair or replacement. For minor corrosion, buy a specialty cleaner at your local auto parts store, or make this homemade one out of baking soda and vinegar.

4. Overcharging and Undercharging

Overcharging can damage a battery’s internal components and cause it to hold less of a charge over time. This is usually a result of defective components, including alternators and voltage regulators.  Overcharging can also damage the electrical system, leading to more a need for more extensive repairs.

Undercharging is often related to other problems. If undercharged, your battery may function but not have enough juice to start your vehicle. This too is a result of either a defect in other components or of the battery’s capacity to hold a charge.

5. Age

You can expect most car batteries to last between three and five years. This can vary depending on the quality of the battery and how well you maintain it. Older batteries may also struggle to power your cars interior lights and other electrical components.

If your battery is not that old, and you have ruled out other possible causes, failure could be the result of a manufacturer defect. Check on warranties or contact the company to see what solutions they can offer.
