What Causes A Car Battery To Die Quickly?

Typically, there is a broad spectrum of factors that could lead to a dead car battery. Occasionally, car batteries wear and tear after several years of use.

When this happens, it is often advisable to replace the battery. Needless to say, some issues will need repair. Always get a professional to check your car battery, especially if the battery keeps dying. So, what causes a battery to die quickly?

Factors causing a car battery to die quickly

As mentioned earlier, a dead battery results from a wide range of factors. However, battery issues often result from a defective electrical system and a simple user error.

Before you repair the battery, ensure you analyze the source of the problem. It is possible to fix minor problems by yourself.

But car experts advise hiring a professional mechanic. Let’s look at some of the factors that make a car battery die quickly.

Leaving Headlights on​​​:

Leaving your headlights on is never a good idea. Headlights source energy from the battery. Thus, they can drain the battery if left on for an extended period.

Always switch off your headlights when they are not in use. Also, putting the headlights on a dim setting can make the battery die quickly.

Switch off all your interior lights when necessary. Nevertheless, note that some headlights are uniquely designed to stay on for a long time.

The battery is weak or in poor condition:

Generally, if you don’t take good care of your battery, it can die quickly. Therefore, evaluate your car battery from time to time and fix all existing problems.

A weak battery will undoubtedly die quickly. Luckily, a wide range of techniques helps you keep your car battery in good shape.

Corroded or loose battery connections:

A corroded battery will die quickly due to lack of charge. A corroded car battery will hinder the charging system from charging the battery.

So, there are high chances that your battery will die when you are driving. A faulty battery connection is also a major cause of a dying battery.

Other parasitic drains in the electrical system:

Parasitic drains are one of the number one causes of a dying battery. Some of these drains include the trunk lights and the glove box. Beware of all parasitic drains in your electrical system and switch them off when necessary. For example, switch off your trunk lights when not in use.

Extremely hot or cold temperatures:

Did you know that extreme temperatures can lead to a dead car battery? However, temperatures only affect a weak battery.

Extreme temperatures can help you identify the problems in your battery. Car owners should constantly examine their car batteries and implement the best maintenance techniques.

This way, they’ll extend the durability of the car’s battery.

Defective charging system:

Your car battery can also die when driving because of a faulty charging system. If your charger has a problem, your battery won’t be able to charge well.

For instance, if you have stretched or lose belts, your alternator will most likely fail to charge the battery. Nd this can lead to a dead battery.

Examine and maintain your car battery

At times, you may not be able to identify any signs of a failed battery. Your headlights could be okay, your battery could be free from corrosion, but your car won’t just start.

In such a scenario, identifying the root cause of the problem requires you to examine the battery itself. More often than not, a poorly maintained battery would not be able to retain charge for an extended period.

Ensure that each battery charge contains enough electrolyte levels. When the electrolyte level drops in the car battery cells, your battery is likely to die.

Consider filling your battery cells with distilled water. Then, use a hydrometer to find out the level of electrolyte in every cell.

Doing this helps you identify and fix all problems inside the battery. Low electrolyte levels in your battery cells will require you to replace the battery cell.

When evaluating the car battery, it is advisable to wear protective garments. Remember, car batteries can explode quickly under certain conditions.

Look out for battery corrosion and loose connections

Car owners should constantly check for corroded batteries. Conduct a visual inspection of your battery at least once a week.

Check for any signs of corrosion and defective electrical connections. You can easily identify corrosion since it appears as a thick blue or white film on the surface of the battery.

Corrosion prevents charge from getting to the battery from the alternator.

Fortunately, you don’t have to replace your battery to get rid of corrosion. Instead, all you need to do is gently scrub the battery using a soft toothbrush and baking soda solution.

Once you complete scrubbing, rinse off the battery and leave it to dry. As you clean the battery, avoid pouring baking soda solution on the surrounding surfaces. You can also use sandpaper to remove corrosion from the battery.

All connections in the battery should be secure. Always tighten loose cables. A loose battery cable interferes with the charging process. As a result, the battery becomes more susceptible to dying.

How to prevent my car battery from dying quickly?

On average, most car batteries have a lifespan of two to three years. You can prolong this lifespan if you take good care of your battery.

Always clean your battery to prevent corrosion and fix any loose cables and connections. Switch off your headlights and interior lights when the car is not in use.

Also, repair all problems in your car battery immediately.

Final thoughts

Typically, many factors can lead to the quick death of a car battery. Some of them include faulty connections, headlights, a radio system, and low electrolyte levels.

You can prevent these causes by taking good care of your car batteries. As a car owner, it is crucial toexamine your car batteries constantly. Ensure they are in good shape at all times.
