Only just realised that the little slot on the battery cover of HRM, cadence sensor etc is exactly sized to be opened using the CR2032 battery you’re about to replace. I’ve been using actual coins, butter knives and fork handles all this time
Obvious. But the issue is normally that I don't have any batteries lying around to use to open it other than the one IN the HRM strap and I don't want to use the new one, because I avoid touching watch batteries, so the skin oils don't contaminate it.
