Car batteries are components that function to store and supply electrical current to various electrical components of the car. Therefore, their presence is very much needed. However, there is one major problem that often occurs with car batteries, which is suddenly running out or being drained. 

So what causes a car battery to run out on its own? And what is the best solution to face this problem? For more details, please pay attention to the following review. 

1. Age factor

The cause of a car battery suddenly running out is usually mostly due to the age factor of the battery that is old. Generally, a battery has a lifespan of two to three years depending on maintenance and usage. An old battery usually causes the electrical capacity of the battery to weaken, making it easily drained. 

2. Incorrect battery usage

Incorrect battery usage, such as excessively turning on the AC and using the audio player while the car engine is off, can also cause the car battery to run out on its own. 

3. Many installed accessories

A car battery that suddenly runs out can be caused by the many accessories installed due to improper car modifications. Modifying a car is a common and acceptable thing for automotive enthusiasts. However, modifying a car by adding excessive accessories such as projector lights, audio, cabin lights, and other electrical accessories can also increase the electrical consumption of the battery, making it easily drained. 

4. Short circuit in the cables

A short circuit in the cables connected to the car battery can also cause the car battery to drain quickly. 

5. Wear on car components 

A car battery that drains quickly can also be caused by wear on car components such as the regulator or alternator. As is known, the alternator is a component that functions to supply electrical current to the battery. If this component is worn out, the battery cannot receive electrical supply properly. 

6. Extreme weather 

Extreme weather can also cause a car battery to drain suddenly. This is because excessively hot weather can cause the electrolyte fluid to run out quickly. Meanwhile, excessively cold weather can cause the electrical capacity of the battery to decrease. 

7. Lack of usage 

Lack of battery usage, such as the car engine not being started for a long time, can also cause the car battery to drain quickly. This happens because the battery does not receive electrical supply from the car, causing the electrical capacity of the battery to decrease. 

Best Solutions to Prevent Car Battery from Draining 

Here are the best solutions to address this issue. 

1. Use the battery wisely

To prevent the battery from draining easily, you need to use the battery wisely, such as turning on the car AC and electrical accessories only as needed, not turning on the audio player when the car engine is off, and disconnecting the battery when the car is not used for a long time. 

2. Regularly check the battery condition

Next, you need to perform regular checks and maintenance of the battery. Check the condition of the cables or alternator for any issues. If damaged, immediately replace the component. Also, check the electrolyte fluid and the strength of the electrical capacity with a hydrometer. If the condition is already drained, immediately replace the battery with a new one at an official Daihatsu workshop. 

Thus, the review regarding several factors that cause car batteries to drain on their own along with their solutions. Hopefully, it is useful.
