I have Polar A5â„¢ heartrate monitor that has died from lack of use 😉 [they only last about 2 years, and it’s been at least that long since I used it].
To get it working again will require me to send it to one of their service centers and pay $$$ to have them change the battery. Or I could do it myself. A set of jeweler’s/technician’s screwdrivers and a little elbow grease and the back comes off, no gasket or seal. I guess the rubbery casing is supposed to serve as a gasket and the cover. The battery is a standard CR2023 3v button battery, available everywhere.
I’ll see if I can get one tomorrow and find out if this thing works. Watching the steady increase in table muscle over the past couple of weeks has gotten pretty alarming: something’s gotta give, besides my waistband.
Well, that was easy enough. A new battery gets it working again, but the heart rate sensor is likewise kaput, no battery life left. And as best I can tell, it’s not user-serviceable. The prices for them aren’t very, er, elastic. So $40 stands between ignorance and really knowing just how bad of shape I am in. As it is now, with just my details, the thing says I am overweight, with a BMI over 25.9. I bought a battery so I could be insulted?
Or I could buy this newer one — with the chest band/sensor — for 2 bucks less. Decisions, decisions.
