The reason is that high temperatures increase the speed of chemical reactions inside the battery. In addition, heat from the engine compartment also causes the temperature around the battery to increase sharply, accelerating the degradation process of internal components.
This is the reason why many vehicles have electrical problems or cannot start during prolonged hot days.
The average lifespan of car batteries usually ranges from 3 to 5 years, depending on usage conditions and operating environment. Therefore, battery inspections should be carried out periodically, especially before long trips or during peak heat.
When checking, technicians often assess voltage, battery retention capacity, the condition of the connecting poles as well as the reliability of the installation position. Excessive vibration during operation can also reduce battery life.
Car owners should start checking the load-bearing capacity of the battery when the car has been in use for about two years and maintain periodic inspections once a year afterwards. This helps determine the actual condition of the battery and predict when to replace it to avoid unexpected incidents.
In addition to periodic inspection, the battery life is also an important factor to monitor. When replacing new ones, car owners should prioritize products with the nearest production time to ensure performance and lifespan.
To limit battery damage due to hot sun, car owners should maintain regular car use to keep the battery fully charged. If the car has to be parked for a long time, you can use a suitable maintenance charger to avoid running out of power.
In addition, you should prioritize parking in a garage or shady place to reduce the temperature affecting the engine compartment.
Car owners also need to limit the use of electrical appliances such as headlights, sound systems or other accessories when the engine is not working because this will quickly drain the battery.
In addition, regularly cleaning the battery terminals to remove dirt, sediment and corrosion marks also contributes to maintaining stable operating performance.
