Tpms Sensor Battery Life

Tpms sensors don t broadcast a continuous signal but only broadcast when the vehicle is in motion.

Tpms sensor battery life.

It s time to charge up tire dealers customer education campaigns for tpms sensor replacement as the life expectancies of batteries molded into sensors begin to run out. The initial expectation was that the sensor s batteries should last 5 6 years and some did fail within that window some failed even sooner. However it s important to understand that the service life of the lithium ion batteries inside tpms sensors can be 5 to 10 years. Tpms sensor batteries have an estimated lifespan of 5 10 years or 100k miles.

Driving habits greatly influence the number of rf transmissions a sensor makes in its lifetime. In 10 years we have encountered a lot of tpms sensor related issues but i believe the largest issue we face today in terms of frequency is battery failure. Due to their location tpms sensors can be damaged by flat tires accidents pot holes etc. Five to six years is a more typical lifespan for older tpms sensors.

If the battery fails its time to replace the sensor unit. When asked how long the sensor batteries will last industry representatives provide a broad life expectancy range of five to seven years and up to 100 000 miles are mentioned when addressing estimated life spans. The lithium ion batteries inside tpms sensors may last anywhere from five to 10 years. Tpms life expectancy is directly related to the number of radio frequency transmissions the sensors make.

This means that eventually a complete replacement of the system will be necessary. Even then the signal is intermittent to conserve battery life. The estimated life expectancy of an oe tpms sensor is 5 to 12 years with the average lifespan being 7 years.
