What Battery Size Do the TST TPMS Systems Use

Question:

Are the batteries on the sensors replaceable? Also, do you need to be moving for the sensors to report to the monitor? Lastly, can you install the passthrough sensors on rubber valve stems?

Yes, the batteries on the TST TPMS for RVs - Color Display - Signal Booster - 4 Flow Through Tire Sensors
Item # TST-507-FT-4-C can be replaced with a CR1632 battery. You do not need to be moving for the sensors to be working, but the flow through stems are not compatible with rubber valve stems- only steel, chrome, or nickel valve stems. Instead you would need to use the # TST-507-RV-4-C which can be used on rubber, steel, chrome, or nickel valve stems and use CR2032 batteries.
