When a lithium battery is brought on a plane, strict regulations must be followed due to safety risks. Carry-on luggage is preferred for these batteries to ensure any issues can be quickly addressed. Batteries should have a charge of no more than 100 watt-hours; those between 100-160 watt-hours may be allowed with airline approval. Spare batteries must be protected to prevent short circuits, typically by keeping them in original retail packaging or by taping over the terminals. Checking in lithium batteries, especially spare ones, is highly discouraged or even prohibited by most airlines.
