7 Reasons Why Your Car Battery Keeps Dying

Car batteries can die for many different reasons.

Do you frequently experience issues with your car battery dying and find yourself having to jump start or replace it frequently? If yes, you're not alone. Car batteries can die for many different reasons and understanding why yours keeps dying can help you determine the best course of action for a fix. Here are seven possible explanations as to why your car battery might be failing on a regular basis.

Why Do Car Batteries Die?

There are many possible reasons for a car battery to die. However, all these issues can be categorized into three core groups: battery problems, electrical system issues, and mistakes by drivers. While some may call for professional help from a mechanic, many others are fixable at home – with a little knowledge.

It’s also important to note that when most people talk about a battery dying repeatedly, they're referring to a deep-cycle battery, which is designed to be regularly completely discharged and recharged, as opposed to a starter battery, which is designed to only be used when starting the car engine.

Top Reasons Why Your Car Battery Keeps Dying

1. Headlights or dome lights left on​​​.

One of the most common causes for a dead battery is when something electrical is left running in the car and drains the battery. This can be as simple as leaving dome lights or headlights on too long, which can happen if you forget to turn them off after parking your vehicle.

2. Corroded connections​​.

Corrosion may build up over time on the battery terminals and prevent power from flowing. This is especially common in cars that are not driven very often, as there's less electrical activity to help keep these connections clean.

3. Old age​​​.

Just like any other car component, batteries are subject to wear and tear over time. This is caused by regular usage and environmental factors. If your battery is old, it's probably a good idea to consider getting a replacement.

4. High electrical draw​​​.

Using subwoofers or amplifiers regularly in your car can drain the battery excessively and lead to premature battery failure.

5. Extremely hot or cold temperatures.

Extreme temperatures can cause battery fluid to evaporate or freeze, both of which can prevent your car from starting. If you reside in a place with severe weather conditions, it might be necessary for you to purchase a battery that can withstand temperature variations.

6. Charging system problems.

If there is a problem with your alternator or other charging components, your battery may lose power and eventually fail. Typically, this happens due to issues with a component or the wiring.

7. Faulty battery​​​.

Sometimes the issue may be with the actual battery itself, such as if one of the cells has gone bad. Premature battery failure can occur when the battery is unable to hold a charge properly.
