I wonder how long they do last.

The sensors on my DW's 2008 Escape are still the OEM batteries. They are the "band type" not the "valve stem type". That's almost 11 years and still working.... Yes, I did let the "summer air" out of the tires last year to be sure the TPMS light on the dash came on when the tire hit a low pressure point. All of her tires activated the system at 20 PSI.
My 2010 F150 and both the 2013 and 2015 F250's never had a problem with battery failure or battery output. I do know that when mounting new tires, Ford recommends checking the battery/TPMS wheel sensor and replacing if defective.... No definition of what "defective" means, even from the service advisor. So......
According to one "Tire expert" the batteries in OEM TPMS sensors last 5-11 years with 7 years being the mean.

I guess my DW's Escape is "living on borrowed TPMS battery time"....
