1- Battery exhaustion Battery is one of the consumable parts of the car that loses its efficiency over time. The useful life of a car battery is usually between 24 and 30 months. After this period, this part loses its power due to corrosion and sulfate and cannot store the required energy well. Regular battery testing is one of the best ways to ensure its charge status and proper performance.When your car battery is worn out, the car will not start and turn on as well as before. to be Also, there may be signs of swelling or small cracks on its body. If you are interested, you can read the article on the reasons for the car not starting.
2- Defective relay switch
The relay is used to prevent too many wires in the car. By using the relay, the wiring of the car will be more orderly and the electric parts of the car will be in a more suitable condition. If the relay switch is broken, the car's battery will be constantly discharged. Imagine that the relay switch is stuck in the "on" position, in this case, even when the car's engine is off, electricity will flow. This issue not only drains the car's battery, but also damages the part where the relay is stuck.
3- Sleeping the car for a long time Not using the car for a long time or putting it to sleep is another reason for the weak and damaged car battery. The car consumes electricity even when it is turned off. Some car systems, such as the locking system, alarm, navigation, etc., also need electricity when the car is off and get the energy they need from the battery. This issue drains the battery charge.To prevent this problem, we recommend that you drive your car at least once a week for 10 minutes to keep your car battery healthy. .
4- Driving a short distance As mentioned above, the battery is charged through the alternator and when the car is on. But to fully charge, you have to drive your car for a very long distance (as much as a trip). The car's alternator cannot fully charge the battery for short distances within the city.
5- Alternator failure When the car engine is on, the battery is charged by the alternator. A damaged alternator disrupts the full and optimal charging of the battery and leads to its premature failure. 6- Improper operation of the car's electrical system Basic and standard car wiring plays an important role in the health of the car battery. When installing car electrical equipment such as auxiliary lights or audio system, you should check their wiring and make sure of its integrity. Improper wires or faulty fuses will drain the battery and shorten its useful life. When leaving the car, make sure that the headlights are off because leaving the lights on for a long time while the engine is off is another It is one of the destructive factors of the car battery. 7- Extreme cold and heat Car battery is sensitive to extreme cold and heat. Temperatures above 100°C and below 0°C can disrupt its performance and reduce its useful life. Therefore, we recommend that you avoid parking your car under direct sunlight on hot summer days. If you don't have a garage or covered parking, you can use a car tent. Periodically, test the health of your car battery by visiting a trusted auto repair shop. 8- Failure to properly maintain the battery Sometimes people's negligence is the main reason for car battery failure. Leaving the radio, recording system, or interior lights on too much when the car is not running will drain the car battery and cause premature failure. Also, if you overcharge the car, the battery will definitely be damaged. For example, install a powerful sound system that works with high amps on your car. In this case, the car's battery cannot supply the electricity required by the system and it is damaged. 9- Lack of regular service You should always check the different parts of the car, including the battery, and if necessary, take care of it and perform the necessary services. If your car battery is acidic, you should periodically check the amount of liquid every week or every two weeks and add it if necessary. Sediments and sulfates cause the battery to deteriorate, which you should be aware of by periodically checking and cleaning them using appropriate methods. 10- Improper charging If the battery is charged more than its capacity, the possibility of failure and reduction of its life is high. Also, consecutive charging in a short period of time will damage the battery. You should check the battery and alternator regularly to know if it is charging properly. Sometimes, due to a problem in the dynamo, a lot of electricity may be generated and stored in the battery, which causes this part to fail. 11- impact, pressure and shaking Battery is vulnerable to strong shocks, excessive pressure, shocks and vibrations. Try to move the battery less and make sure it is firmly in place.
