TPMS batteries expiring yet ?

Read an article stating the typical life of a tire pressure monitoring system battery is 6 to 10 years. Each tire has a battery to power the transmitter to feed info to the computer about tire pressure. Has anyone been told they had to buy a new sensor/battery as they are one piece. What year was the car when you had to replace it? Wondering how long the actual real world life is.
