Garmin short heart rate transmitter strap lifespan

Start using the new strap a year ago. This was to last 3.5 years. Recently, Jan 2020, after about an hour of riding the transmitter showed an abnormally low reading. I checked the battery, which was not exhausted, but I installed a new one just to be sure. On the next ride exactly the same thing happened. Then on my next ride I used a new transmitter purchased in (fall 2019), and it worked normally. My rides are of normal duration and frequency so the transmitter show have lasted at least for 3.5 years.

Any info or recommendations appreciated.

  • Yes I have had some issues with the HRM transmitter - do your buttons on the transmitter appear brown or blacken'd around the outside of the button?  I had one fail that way... and another warrantied that way.  I have since started buying via amazon with the 6$ squareup warranty thing... came in handy when i accidentally put it through the washer and dryer... (worked for a while... but eventually died).   Now I have like 4-5 of the soft straps... just one transmitter.    Make it easy to get it washed and have backup lol
