The battery is a crucial part of a vehicle responsible for starting the engine. If the battery experiences wear, the car cannot be started and driven. This condition often raises many questions, one of which is what causes a car battery to be drained? To find the answer, check out the following review.

Causes of a Drained Car Battery and Tips to Overcome It

There are several reasons why a car battery can quickly drain even though it has just been replaced. So, what are the causes? And what should be done if the car battery is drained? Check below:

1. Cars That Are Rarely Used

One of the main causes of a drained battery is a car that is rarely used. It is important to know that a car that has not been used for a long time does not heat up the engine. 

As a result, the battery will not receive sufficient electricity supply. Consequently, the performance capacity of the battery will be less than optimal. Over time, the battery becomes drained, and the vehicle is difficult to start.

The only detectable symptom of battery damage due to a rarely used car is that all electrical components do not turn on properly. To overcome a drained battery, always warm up the car even if you are not traveling. Warm up the car at least once a week so that the voltage supply to the battery works optimally.

2. Excessive Car Accessories

For some people, modifying a car is a very enjoyable thing. Usually, they will change or add components to make it more attractive. 

However, who would have thought that such things could be a cause of a drained car battery even though the battery is still new? Essentially, some car accessories can excessively drain the battery's power.

Some people often add car accessories without considering the capacity of the car battery. As a result, the battery's strength will decrease and become inadequate for starting the engine. 

One accessory that can consume battery power is the audio system. It is important to know that the audio system requires a large amount of electricity.

Actually, it is fine if you want to add an audio system. However, first, pay attention to the battery's strength in the car.

If a high-capacity audio system is left unchecked, over time the battery will be completely drained. This is what causes the battery to wear out or drain. As a result, the car becomes difficult to start.

3. Intensity of Car Use 

What causes a car battery to drain quickly? Continuous use of the car can also lead to a drained battery. This is because a car that is used intensively certainly requires a significant amount of electricity. 

In such conditions, the car battery will be forced to work extra to supply electrical voltage. This is what causes the car battery to drain on its own and results in a drained battery.

Intensive car use can reduce the lifespan of components, including the battery. Essentially, all car components have their own lifespan. 

This lifespan can also lead to damage if the car is used continuously. Therefore, reduce excessive car use.

4. Use of HD Projector Lights

A car battery can drain quickly due to lights that are always on. Similar to the audio system, using projector lights that do not meet standards can also consume battery power. 

So before adding HD projector lights, it is advisable to check the specifications of the lights regarding how much electricity is needed. Through this, you can replace the car battery with a higher amperage to match the electrical needs of the lights.

5. Causes of a Car Battery Draining on Its Own

Nowadays, many people prefer wet-type car batteries. This is due to the many advantages of using wet-type batteries. 

The long lifespan and easier maintenance make wet-type batteries popular among vehicle owners. 

Often, owners of cars with wet-type batteries forget to check them. Suddenly, the battery water is gone, and it does not function as it should.

If this is left unchecked, the battery can drain. The depletion of battery water is generally caused by using the car without checking the water tank.

6. Signs of a Weak Car Battery

Basically, a weakening battery can be detected early. If the car engine is difficult to start, it can be confirmed that the battery condition is weakening.

A weak battery certainly cannot supply electricity to all the engine components in the car. As a result, the car will be difficult to start and cannot be turned on. This condition will certainly be very detrimental to the driver.

In addition to the car being difficult to start, a weak battery can also affect the horn sound. This is often the main symptom of a weakening battery in the car. 

Therefore, always check the car battery regularly. If necessary, always conduct inspections each time it is used to indicate signs of a weak car battery.

As explained in the review, the battery is a component that plays an important role in starting the car.

If the car battery experiences damage such as draining or wearing out, it is certain that the vehicle cannot be used. As a car owner, you must check the battery to keep the car's performance optimal.
