Questions on OEM TPMS Sensors

frankzlin79 · 11-26-2012, 03:54 PM

Does anybody know what type of battery model is contained inside the 2010+ OEM TPMS sensors?

How do you access the battery?

Also what is the typical battery life?

I need to have my TPMS sensors transferred from one set of wheels to another set of wheels. Before I do so, I was considering buying four new batteries for them since I fear that the batteries may wear out before the tires need replacement.

My car is a 2010 M3, so the batteries have been running for about 2.5 years now...My car will be out of warranty in about 7 months so I'm not going to rely on the dealer replacing the batteries for me.

Bottom line, batteries are "entombed" in the assembly, you can't replace them. However, life expectancy is 5-12 years.
