How Long Does the Tire Pressure Monitoring Battery Last?

Tire pressure monitoring built-in batteries typically have a lifespan of 3-5 years, which should be calculated based on the vehicle's usage time. Tire pressure monitoring functions: According to the monitoring method, it can be divided into indirect tire pressure monitoring and direct tire pressure monitoring. Generally, most factory-installed tire pressure monitoring systems are indirect, with sensors usually being built-in. The monitoring accuracy of built-in and external tire pressure monitoring is almost the same. The principle of direct tire pressure monitoring: It uses pressure sensors installed on each tire to monitor the tire pressure in real-time, then transmits the data to the vehicle's computer via a wireless transmitter. The car's dashboard will display the tire pressure data for each tire, and when the tire pressure is too low or too high, the tire pressure monitoring system will automatically issue an alert.
The battery life of a tire pressure monitoring system is typically 5 to 10 years, and I've seen many car owners share their actual usage experiences. Factors affecting it include driving frequency—frequent long-distance trips or city traffic congestion can increase battery drain—and environmental temperature, as extreme heat or cold accelerates battery aging. My own car's system lasted 8 years before alerting me; the dashboard lit up with a yellow warning light, and the repair shop diagnosed it as a battery issue. After replacement, it worked fine. It's advisable to regularly check the system using diagnostic tools to measure voltage, preventing sudden failures that could compromise safety. After all, abnormal tire pressure can lead to blowouts, especially dangerous on highways. Repairs are straightforward, usually costing around 100 to 200 yuan.
I've been driving for over a decade. The lifespan of TPMS batteries varies by usage—mine lasted 7 years with mostly city commuting before depletion. When it failed, the dashboard displayed a warning, and I promptly had it repaired at a reasonable cost. I've heard that infrequent driving or prolonged outdoor parking under direct sunlight may shorten battery life by several years. I maintain proper tire pressure to reduce system power consumption and extend battery life. Replacement batteries cost around 100 RMB; DIY is possible but requires caution, while professional shops offer faster, safer service. Safety is paramount—without this function, underinflated tires become harder to detect, significantly increasing accident risks, especially during rainy conditions or long-distance driving.
