Battery Replacement of TST TPMS

Question:

The specs for the internal sensor for the TST34FR state Battery life: 12 months - 18 months. That seems to imply one would need to remove the tire from the rim very 12-18 months and replace the sensor. Is that correct?

The TST TPMS, # TST34FR has a rather conservative battery life listing of 12 to 18 months with feedback indicating greater real world usage lifespan. But yes, when it is time to replace the battery, you will of course need to remove the tire.
