Carry-on details
Allowed. CR123 batteries are single-use lithium-metal cells, commonly used in cameras and flashlights. Consumer CR123 cells fall well under the gram-based limit for lithium-metal batteries, so no airline approval is needed for spares.
Checked-bag details
Not allowed. Like other spare lithium batteries, loose CR123 cells can't go in checked baggage — they must stay in the cabin.
Special instructions
A CR123 battery installed inside a camera or flashlight follows the installed-battery rule instead, which is allowed in either bag (carry-on recommended).
