Most external TPM sensors use "watch" style batteries like CR1632 or CR2032 available at many Box drug stores and grocery stores.
My experience has given me 1 to 2 years of use. But When I winterize and park the RV for months at a time I pull the sensor which both saves the battery and protects the sensor from freezing.
If the battery gets low your monitor will sens a signal indicating lost signal (different systems have different symbols ) but to my knowledge, all aftermarket systems have this warning. One alternative is to simply carry a couple of extra batteries and swap them out at the nest rest or fuel stop or just replace the batteries once a year. After a few years of use, you will learn your system normal life.
Changing is a one or two-minute process at most.
