Lithium-ion batteries in checked luggage violate US DOT regulations and can result in significant civil penalties from the FAA, while carry-on transport is permitted under specific conditions
TSA and FAA have different enforcement approaches, with TSA sometimes not enforcing DOT carry-on provisions while FAA actively enforces them
Professional camera batteries like Dionics and Preston batteries can be transported as carry-on luggage on many flights without issue, though individual airline policies vary
Spare lithium-ion batteries should remain in carry-on luggage rather than checked baggage to minimize fire risk
Batteries exceeding 160Wh may face restrictions on some airlines and routes
Carrying printed copies of current regulations and original battery packaging can help resolve questions with TSA inspectors
International flights and different airlines have varying levels of enforcement and clarity on lithium battery transport rules
Intentionally circumventing battery transport rules risks substantial fines and legal consequences

The regulations and enforcement practices described apply specifically to US domestic and international flights as of 2008
Different airlines and international jurisdictions (such as UK to Caribbean route mentioned) have unclear or inconsistent enforcement of lithium battery rules
The discussion includes anecdotal accounts of non-enforcement rather than comprehensive documentation of current policy
High-capacity batteries such as 190Wh units may exceed checked baggage limits regardless of packaging or installation on chargers
No definitive answer provided regarding whether battery restrictions apply universally across all airlines and destinations
