    So far I seem to have been able to successfully replace the batteries in my TPMS sensors. I picked up my 2015 XRx in January of 2015, so it's been really close to 5 years. Baby got a new pair of shoes (Anakee Adventure's), so I thought it would be a good time to address the sensor battery life issue. I have the Cheap+ gene on my Y-chromosome, so I thought I'd try to avoid the $250 part cost plus the stealer... err, "dealer"... programming fee by rolling my own.

    The only issue is that the original batteries are CR2050W's and I couldn't find a source unless you want to buy a thousand. (Let me know if you find one.) I used CR2032's with tabs and so far they are working. Both batteries are 3V lithiums and are the same size. The 2050's are "high temperature" tolerant and have about a third more capacity.

    The battery and circuit board are sealed in a rubber-like material. I used an xacto knife to cut out the material around the battery and solder terminals. You only have to remove material from the round end. This leaves the circuit board on the other side safe.

    Here's the 2032 soldered in place.

    I had some Starbrite's Liquid Electrical Tape around and used that to seal it back up. It comes out as a thick liquid and dries to a rubber-like consistency. It shrinks some when dry and looks pretty much like the original!

    I'll let you know if these have temperature issues. I'm in SoCal, so I'll be riding all winter.

    The TPMS batteries are still working in my 2006 Tacoma.

    Clear win! I have two sets I bought when I picked up the his'n'hers 2015 800 XRx's, then bitched at the stealer's flat $100/wheel to do whatever ECU magic Triumph won't trust the owners to do. Since then I've found a dealer that will do them for $25 for both (ASSuming I install them in the wheels)... but those sensors are now 5 years old, so probably dead.

    Now I have a winter project...

    I wish they had tabs. I can't find any with tabs. I have successfully soldered directly onto sub-C batteries, but I don't know about these little button cells.
