I'm using these cells in SmartThings sensors. Some of the S.T. sensors have a very short tab for the + terminal to make contact with the outer edge of the battery.These batteries have ever so slightly less "sidewall" for the + terminal to contact than the name brand Duracel or Panasonic batteries. It's under 1mm different but it is enough to leave the + terminal waving in the wind.Use a bit of foil or a couple strands of wire to bridge the gap and you're good to go.I guess specifications are not for everyone.
