I have a few used TPMS, 4 of which I need to install in my Volks when I put new rubber on. I am wondering if anyone knows how I can tell how old the TPMS are, or battery left in them. I guess the best method would be to contact Schrader and see if they can tell me from Serial number. Any ideas?

Schrader claims a life of 7 years. I doubt they track individual sensors for life but you can certainly try.

The problem is I might have some from an 03 and some from 06, or 07, no idea.

Last time I brought the used tpms to the dealership, they were able to read if the signal off the tpms were strong or weak.

I wonder if the tire shop or dealership can tell the battery level with their tpms reader devices?

Thats interesting. Thats good info. I might have to look into that.

Is the battery replaceable?

No, they are sealed from what I understand.

Typical life is years. Battery is sealed in the unit so when its dead you have to buy a new sensor.
