What to Do When the Built-in Tire Pressure Sensor Runs Out of Battery?

[VanDawson]

The built-in tire pressure monitoring system requires battery replacement when it runs out of power. The batteries used in built-in tire pressure monitors are generally disposable, with higher-quality ones lasting 3 to 5 years and lower-quality ones lasting 2 to 3 years. When the battery dies, it means the tire pressure monitoring system has reached the end of its life and needs to be replaced entirely. The built-in tire pressure monitoring system uses pressure sensors installed inside each tire to directly measure tire pressure. A wireless transmitter sends the pressure information from inside the tire to a central receiver module, which then displays the data for each tire. The system automatically alerts when tire pressure is too low or there is a leak. In contrast, external tire pressure monitoring systems use sensors that replace the valve cap, fitting directly onto the valve stem. By pressing the valve core inward, the internal tire pressure is released, allowing direct detection of tire pressure and temperature. The built-in system is less affected by external temperature and road conditions, has a longer lifespan, and does not require frequent disassembly, making it more stable. However, since the sensors are installed inside the tire, professional installation at a repair shop is necessary, and wheel balancing must be performed.
