Servicing OEM TPMS at the wheels

[artfuldodger]

Are there batteries on the sending units of each wheel and if so when I get new tires(on my 2011 f350 srw) will the installer change them upon request?

As far as I know the OEM TPMS does not have replaceable batteries in them you have to replace the hole sensor.

This is off a reputable website
One of the most common questions I get asked is, what is the life expectancy of the TPMS sensors? Followed by can the battery be replaced? Both are very good questions with sometimes some not so good answers. First question, up to seven years, for the average consumer this is great 7 years is longer then most people retain cars. Second question, No unfortunately not, like an Ipod the sensor has an encased battery that once used up cannot be replaced.

When asked how long the sensor batteries will last, industry representatives provide a broad life expectancy range of five to seven years and up to 100,000 miles are mentioned when addressing estimated life spans. The follow-up qualifier is that driving conditions, such as frequent on-off cycling of a TPMS, tire pressure sampling frequency and temperature extremes, will significantly shorten battery life. Translating to they cannot guarantee a specified amount as many things affect battery sensor life.

Thanks! One of mine is starting to screw up.
