TPMS Max. battery life?

I've been researching TPMS battery life and the general "concensus" is that as a vehicle approaches 100K miles the TPMS may be reaching the end of its life. There are two measurements: years and mileage. As the TPMS will go into "sleep mode" when not being used (car not being driven), mileage may be the best determination of life. Beru's "1st generation" TPMS is given a "max" of 90 months...perhaps based on an "average" driving scenario (in the U.S. about 14K per year):

Beru Technical Information
Battery Life - Generation 1 TPM sensors have a maximum battery life of 90 months after activation. Generation 2 TPM sensors offer a maximum of 120 months. However, Generation 1 TPM Sensor types are now supplied in Generation 2 style packages. The date stamp on the sensor is simply a manufacture date and new unactivated Beru TPMS sensors can safely sit in their boxes on the shelf for many years without draining the battery life.

Info from "tpmsdirect""


TPMS diagnostic tools (available at tire dealers...Indy shops) can determine the remaining battery life in TPMS units...such as "15%" but this may indicate another year of functionality.

If mounting new tires at "high mileage" it may be worth while to consider if the TPMS sensors should be replaced rather than endure "failure codes" on the dash (which can't be turned off), and expensive tire dismounting later on.
