Terminal voltage on a coin cell is 3V, so you have to use a pair of AAAs, not just one. Ends up requiring ten times the volume. Shelf life on lithium batteries

Terminal voltage on a coin cell is 3V, so you have to use a pair of AAAs, not just one. Ends up requiring ten times the volume.
Shelf life on lithium batteries is longer, and they don't leak, so you can ship and store sensortags with the battery preinstalled.
My impression is that it's way more of a logistics thing than a customer-value thing.
