I just got my Ruuvitags (cool!), however one of the tags arrived with a dead battery. The plastic film was in place, so it seems like an empty battery was installed in assembly(?). The tag itself seems to be OK, when I tried it with the battery from one of the other tags.
I’m wondering what is the correct type of battery to use though. Your site says CR2477, but the failed battery is a CR2450HT. Which one should it be? Does it make a difference which of the two to use?
