Why Does My Car Battery Keep Dying? – Step By Step Guide

While most car batteries last for years, they’re also subject to wear and tear over time. This makes them susceptible to problems such as leaks, corrosion, and low voltage.

When your car battery dies, it can mean one of two things, Either your vehicle is in need of a jump start or you have a problem with your car’s alternator. This article will explain why does my car battery keep dying.

While driving on the highway, your car battery may suddenly stop working. If that happens to you, don’t panic. The reason for this sudden power outage is often simple and easily fixable.

We’ll explain why your car’s battery will sometimes go dead and we’ll show you how to fix it quickly and safely. But first, you need to learn why my car battery is dying. 

6 Reasons Your Car Battery Keeps Dying:

We all love our cars, and there’s nothing better than taking a drive in the country and enjoying the scenery. But what if your car battery starts to die and you can’t get a jump? Well, here are some common causes for a dead battery that could help you avoid a costly car trip to the mechanic and maybe even save your car from being towed.

Car batteries are pretty amazing. They are small, light, and compact, but they can hold a ton of energy. But when your battery is old or damaged, you might have to buy a new one. It can be expensive, but we’re going to show you what the real reasons are behind your battery dying and how to fix them for free.

1. You Left Your Headlights On:

You leave your car lights on, your battery dies, and you’re left stranded. You’re not alone: this happens to all of us at one time or another. 

When your headlights are on, they’re draining your car battery. That’s because your headlights are powered by your car’s battery, and if the battery is low, your car won’t start.

To avoid this problem, turn your headlights off. That way, your battery won’t drain, and you won’t have to worry about it going dead.

2. Something Is Causing A “Parasitic Draw”:

Your car’s battery can be drained by something other than your headlights. 

When your battery is low, your car won’t start.  This problem is often caused by something called a “parasitic draw.” A parasitic draw is something that drains your battery when your car is off.

3. Your Battery Connections Are Loose Or Corroded:

Besides the obvious problem of being dead, loose or corroded connections can also cause your battery to drain. Loose connections can allow air to enter the battery. That can cause your battery to drain. Corroded connections can allow acid to enter the battery. That can cause your battery to drain.

4. It’s Extremely Hot Or Cold Outside:

Accordingly, the battery should be in a very stable environment. Always check the temperature of your battery before charging. If it’s too hot or cold, it can drain your battery.

If it’s extremely hot outside, your battery will be hotter. If it’s extremely cold outside, your battery will be colder. If your battery is hot, you may want to open the battery compartment and check the connections for corrosion.

5. The Battery Isn’t Charging While You Drive:

Most of us have experienced that frustrating moment when we try to charge our car batteries while driving. That’s why you’ve come to the right place.

As you already know, the battery in your car needs a constant supply of energy. When you charge the battery, it receives the correct amount of energy. However, if there is a problem with your battery, it won’t get charged. This could happen because the battery is damaged, or the alternator isn’t generating enough power.

6. You’re Taking Too Many Short Drives:

If you’re looking to get more miles per charge from your vehicle, you may want to think about your daily driving habits. A recent study found that taking too many short drives per day (20 miles or less) can reduce your battery life, while long drives (40+ miles) will help improve the performance. 

Driving your car for a long time and a lot is important for you and it’s also important for your car’s battery. If you’re trying to get as many miles per charge out of your car, you may want to consider reducing the amount of time you drive, even if it means taking a few shortcuts.

These shortcuts may include getting off the highway at rest stops, avoiding the use of cruise control, and driving less on the freeway.

Learn How To Fix A Car Battery Drain?

The battery in your vehicle is one of the most important parts of your car. The car battery supplies power to your lights, the engine, and many other components. It is crucial that the car battery works and lasts a long time. This is because if the battery stops working, the car is not able to start, so you may need to get it fixed right away.

It is quite easy to make a car battery drain, and therefore, it is good to know the reason for the problem in order to fix it. By fixing the battery drain, you can make sure that your car battery is safe and lasts for a long time.

You can fix a car battery drain yourself, or you can take it to a professional car battery repair center. let’s have a look at how to fix a car battery drain?

Start By Charging The Battery Yourself:

You’ll need to charge your battery with the same kind of adapter that came with it. It’s important to make sure that you’re using the right one for the size of your battery, as you don’t want to damage the charger.

It takes between 6 and 12 hours to charge a car battery depending on its age and condition. Once the battery is fully charged, jump the car and try to start the engine. Keep in mind that a car battery is only good for a certain number of charges before you have to replace it.

When it starts getting warm to the touch, you know you’ve hit the magic number. Once you start the car, you’ll notice that the battery is recharged.

Use A Deep Cycle Car Battery:

A deep cycle battery stores more energy than an ordinary battery. This means that it can last much longer. It’s ideal for long-distance drives. A deep cycle battery can store a lot of energy, but you’ll need to make sure you keep it clean.

You can get a deep-cycle battery from your local auto parts store. They usually come in two different sizes, 12 volts and 24 volts. The latter is a bit bigger, so it’s a bit more expensive.

It’s also important to keep a deep cycle battery at a reasonable temperature. When the temperature drops below freezing, you’ll lose power and start draining the battery. If it gets hot enough, it will damage your battery.

The best way to keep a battery warm is by charging it in the car. You’ll also want to store it in a shady place. That means keeping it away from direct sunlight.

Clean The Battery:

To get the best battery life, it’s important to clean your battery.
