How Often Should the Tire Pressure Sensor Battery Be Replaced?
1 Answers
Tire pressure sensor batteries typically last 2 to 3 years, with a general recommendation to replace them every 2 years. However, original equipment manufacturer (OEM) batteries have a longer lifespan, usually lasting 8-10 years or even longer. There are three common types of tire pressure monitoring systems: Direct Tire Pressure Monitoring: Direct tire pressure monitoring systems use pressure sensors installed in each tire to directly measure the tire's air pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts the driver when the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the air pressure in a tire decreases, the vehicle's weight causes that tire's rolling radius to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Tire Intelligent Monitoring System: This system combines the advantages of the two systems mentioned above. It is equipped with direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to a fully direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires, as a direct system can.
