The T31 transmitter on my Polar Electro has broken at one end and is now unwearable. After dutifully trolling the internet for this cheap trash POS, it is apparently a common problem, not only for the heart transmitter, but also for their cheap trash POS watch bands.
Rather than pay prime replacement rate for a Polar Electro T31 cheap trash POS, I have decided to fix this cheap trash POS Polar Electro T31 myself.
Good luck getting me to ever purchase another cheap POS manufactured by Polar Electro.
Should you ever need to replace the battery in this thing, there are plenty of videos covering instructions on how to replace the transmitter battery. It’s a heck of a lot cheaper than paying for a new heart transmitter, considering the battery is only a couple of bucks.
