    Potted TPMS sensors - battery

    This is what my TPMS sensors look like. They are potted/sealed. I can see from earlier posts on this subject that it is still possible to change the battery in them, but Iím not sure how to remove the battery to change it. I could carefully cut around the edge of the potting compound and try to prise it out but I am worried about damaging the circuit board. It would be a great help if any of you who have successfully replaced a battery in this type of sensor could explain how you managed to remove the battery and replace it. Also how you resealed it after replacement. Thanks in advance for your
    help.

    With a small cutter you can and removing the rubber that covers the battery. I leave you some photos so you can see where the battery is located and you will see that there is no risk to remove the battery.

    Thanks for that advice Digital. Did you manage to find new batteries with identical tabs on, in order to solder them to the circuit board connections? Also, after installing the new batteries did you reseal over the top of them with silicone or similar?

    I buy this type of battery with positive and negative leads, cut the sheets off the old batteries, and solder the positive and negative leads from the new batteries to the sheets cut from the old batteries

    Once the batteries have been replaced, I place a piece of heat shrink sleeve 4 centimeters wide

    With this type of heat gun, I blow hot air so that it sits on the TPMS sensor


    This is the final result of how the TPMS sensor is well seated and protected

    I've only had my bike out for 3 rides this year.  First 2 were about 25 miles each. On both rides it took about 2 miles for the front & rear TPMS readings to show, and the rear would show before the front.   I figured the batteries were going out ( 2015 with 25K miles ).  When the batteries went out on my Concours  ( same LDL sensors, except for the frequency they use) they acted about the same.

    I was fairly confident the readings would show up after a few miles for awhile but on a 455 mile ride ( from my home ) Sundy to the Pittsburg area for the start of the IBR, the front went out completely.   I learned the TPMS trouble light will come on after about 15 minutes after only dshes are displayed.

    So, I decided I would try to replace the batteries and was pleasantly surprised that my sensors are a bit different than Digital's.  Mine aren't potted at all.  Very easy to replace the batteries.  BTW, the old battery was reading 1.886 volts.  These are " 3 volt " lithium batteries.  However, I looked up the specs and discharge curve and they aren't considered depleted until the voltage goes below 2 volts.

    Forgot to mention that I also installed a Shinko Raven front tire, too when I replaced the TPMS battery.
