TMPS battery life?
« on: February 11, 2018, 09:07:35 pm »
I just got a new wheel from ebay to replace the badly bent one I have on the bike.  To my surprise it came with a TMPS on it.  Is there any way for me to determine how good the battery is?

Also, is there any way to swap the stem with another TPMS?  I got a baggy with the bike that had a brand new TPMS in it, but the valve step was snapped in half.  Even if this one is bad, if I can swap the valve stem to that new one, would be great.

The old style stem unscrewed from the sensor body so it sounds like your must be the new style which I don't have any info on.
Only way to test the battery is to dissasemble and put a volt meter on it or put the wheel on and have the TPM registered to the bike with dealer equipment and then go for a ride. The batteries actually last a long time 5 years+ but they do begin giving false low voltage messages due to poor programming.

Oh I think I might have the older style.

That would mean I can swap the battery if needed.


And, this  http://a.co/76fPi2o  is the newer one right?  it's definitely the first one up above.

3 years is the most I've ever got out of the TMPS batteries.
