Normally, the service life of a car battery is 2-3 years, and the original battery of a new car can last more than 3 years. Therefore, if the battery has been in use for about two years, you should pay attention as its service life may have expired. At this point, it is advisable to conduct frequent inspections and perform early detection. If crystallization appears on the battery, it is a sign of aging. Over time, batteries may develop crystallization. First, use boiling water to clean the crystallization thoroughly, and then polish the battery terminals with gauze. Next, check for any cracks between the terminals and the battery case. If cracks are found, seal them with asphalt. Additionally, when adding electrolyte, ensure the amount is appropriate and avoid overflow. After securing the battery clamps, apply Vaseline or grease for insulation, and the issue should be resolved. Address or replace any problems early to avoid sudden battery failure during use, which could lead to losses. Regularly monitor whether the battery voltage is within the normal range and check the status indicators on the battery. If the car does not show signs of power loss and starts smoothly every time, it indicates the battery is in good condition. Also, be aware of poor driving habits that can damage the battery: 1. Forgetting to turn off lights or electronic devices when exiting the car, 2. Not turning off the air conditioning before shutting down the engine, 3. Using electrical equipment excessively without starting the car. Furthermore, a battery tester can be used to check the battery's health. If the battery's health is below 10%, it needs to be replaced; otherwise, the car may fail to start if the battery fails.
