UNDERSTANDING TPMS BATTERIES

摘要

A tire-pressure monitoring system (TPMS) sensor is engineered to perform well and survive under very harsh conditions inside a vehicle tire. Its typical operational life span is five to 10 years - depending on the type of sensor, how the vehicle is used and a variety of other conditions. TPMS sensor batteries are sealed in the sensor housing and cannot be serviced. (When the battery is depleted, the sensor can no longer provide protection to the driver and passengers and must be replaced.
