Car Battery Performance Drop? Here Are the Reasons Why the Car Battery Is Not Charging

In order for the vehicle to run and work optimally, a battery is needed. This component serves as the main supply for the car's electrical system, such as lights and other parts. One common problem is that the battery recharge does not work optimally. So what causes the car battery not to charge? Check out the following review. 

1. There is a Problem with the Cable Between the Battery and the Alternator

One of the causes of a four-wheeled vehicle's battery becoming drained is a problem with the cables or socket connections. This issue occurs due to sockets that are starting to deteriorate or rust until the cables begin to break. This condition will occur in older cars or four-wheeled vehicles that are rarely maintained and checked regularly. 

2. Damage to the Alternator 

The next problem that can cause the battery not to charge is from the alternator itself. As an important part of the car's charging system, the alternator has a significant function. Therefore, if there is a problem or error, this becomes the reason why the car battery does not charge and causes the battery to drain quickly.

In addition, the part of the alternator that often encounters problems is the carbon brush. This component is directly related to the slip ring in the four-wheeled vehicle. If the carbon brush wears out, the connection between the two becomes looser and the battery charging current will be obstructed. Not only that, the IC regulator also has the potential to suffer severe damage. 

If the alternator component is damaged, the electrical supply of the four-wheeled vehicle will not function normally. In fact, the battery serves as a current storage, so if there is no current to be stored, it will cause the spark plugs to fail. 

Moreover, the injection system that uses electricity in four-wheeled vehicles will fail and cause the car to stall. 

If the car engine stalls, then your four-wheeled vehicle cannot be started because the battery water is depleted. This will also impact when you try to start the car, as the starter will not function as it should. 

The best step to address the cause of the car battery not charging is to repair the alternator components.

3. The Battery Does Not Contain Electrolyte

If you have a car that still uses a wet battery type, it can be recharged. This makes its lifespan longer and maintenance easier. 

However, car owners often forget to perform routine checks, causing the battery to lack the electrolyte needed to generate electricity. 

If this is ignored, the substance that generates electricity will be lost. Therefore, you are strongly advised to check it or perform maintenance before traveling. 

This will prevent the cause of the car battery not charging when you are traveling and will not disrupt your driving experience. 

As is known, the use of a battery must be adjusted to your needs. Make sure to always check and perform routine maintenance on your four-wheeled vehicle. Because, this will allow the battery in your car to be used for a longer period of time.
