You do know they have been known to explode, especially when dropped or partially discharged batteries are mixed together in a device? (The least discharged battery will start charging the other battery. This is bad, as regular 123s are not meant to be recharged.)
I don't know what the current TSA ruling is, but they were banned from air travel in any great number.
I am only aware of 2 ~ 3 incidents that CR123A exploded. This is against the backdrop of millions of CR123A batteries in use worldwide. All the explosions are due to a) inferior batteries (without built-in safety feature) b) mixing new & old(nearly exhausted) batteries in devices that draw a big current from the batteries.
TSA ban the shipping of CR123A in cartons. But carrying 1~2 dozen spare for your electronic devices should not be an issue.
