United Airlines battery policy sets clear rules to ensure safe air travel with lithium-ion batteries, power banks, and electronic devices. Travelers often search for United Airlines lithium battery rules, spare battery limits, and power bank restrictions to avoid surprises at the gate.
Key Rules for Lithium Batteries on United Flights
Lithium-ion batteries power most modern gadgets, but United Airlines battery policy mandates they stay in carry-on luggage only. Checked bags cannot contain loose or spare lithium batteries due to fire risks from potential short circuits. Devices like laptops, smartphones, tablets, and cameras with installed batteries can go in checked luggage if fully powered off and protected.
Spare batteries, including external power banks, must remain in the cabin under United Airlines spare battery policy. Each spare battery needs individual protection, such as original packaging or plastic bags over terminals, to prevent accidental activation. United Airlines power bank policy aligns with FAA guidelines, focusing on watt-hour (Wh) ratings for safe transport.
Watt-Hour Limits in United Airlines Battery Guidelines
United Airlines battery policy categorizes lithium batteries by watt-hour capacity for precise compliance. Batteries rated at 100 Wh or less require no approval and can travel freely in carry-on bags. Those between 100 Wh and 160 Wh demand prior airline approval, limited to two per passenger.
