The Federal Aviation Administration (FAA) have created and published a new lithium battery factsheet, which can be found on the FAA’s Pack Safer website.
The website includes the following guidance.
Devices containing lithium metal batteries or lithium ion batteries, including — but not limited to — smartphones, tablets, cameras and laptops, should be kept in carry-on baggage. If these devices are packed in checked baggage, they should be turned completely off, protected from accidental activation and packed so they are protected from damage.
Spare (uninstalled) lithium metal batteries and lithium ion batteries, electronic cigarettes and vaping devices are prohibited in checked baggage. They must be carried with the passenger in carry-on baggage. Smoke and fire incidents involving lithium batteries can be mitigated by the cabin crew and passengers inside the aircraft cabin.
If carry-on baggage is checked at the gate or planeside, spare lithium batteries, electronic cigarettes, and vaping devices must be removed from the baggage and kept with the passenger in the aircraft cabin. Even in carry-on baggage, these items should be protected from damage, accidental activation and short circuits. Battery terminals should be protected by manufacturer’s packaging or covered with tape and placed in separate bags to prevent short circuits.
Damaged, defective or recalled lithium batteries must not be carried in carry-on or checked baggage if they are likely to be a safety concern by overheating or catching on fire.
When in doubt, leave it out.
