Late reply, but for anyone seeing this thread now, FYI, these are garbage. Same with the Loopacell, PKCell, BKCell and whatever other rebranded junk sold on Amazon. I've gone through a full 10 pack of "LiCB" in under 6 months between my two Ecobee SmartSensors, they never last. The recent reviews seem to reflect this. Go with Digikey/Mouser or some other major distributor of OEM batteries. Even the Panasonics on Amazon are hit/miss - some come OEM-wrapped, others come in a Ziploc bag!!
