Subject: RE: Garmin HR Monitor battery life The "weak battery, replace it" symptom I saw in my Garmin strap was spiking to 240 bpm on the bike. The signal couldn't reach all the way to the Edge head unit. Replace battery, no problem. Oh, and to save you some trouble: make sure to take off the sticker that may be on one side of the battery. I've replaced those quarter-sized batteries for years, and never before did the battery have a sticker on one side. But this one did. I found it the hard way by replacing the battery, and the HR strap didn't work at all. I took the strap apart, checked again, put the battery back, still no workee. Bought another battery, and as I was fiddling with it again, THEN I noticed that there was a white sticker on one side of the battery. Took it off, re-assembled, voila, And I felt stupid. :-) Edited by brucemorgan 2014-12-03 8:43 AM
