Are Lithium Batteries Allowed in Checked Luggage? Airline Rules Explained

Lithium batteries are generally not allowed in checked luggage unless installed in a device and meeting strict airline and FAA requirements. Spare lithium batteries must always be carried in your carry-on. Devices with lithium batteries in checked bags must be powered off and protected from damage or accidental activation. Always check your airline’s specific policy before flying.

What are the basic rules for lithium batteries in checked luggage?

Lithium batteries are largely restricted in checked luggage due to fire risks. Only lithium batteries installed in devices may be placed in checked bags, and these devices must be completely powered off and protected from accidental activation. Spare lithium batteries, power banks, and loose cells are strictly prohibited in checked baggage and must be carried in the cabin.

How do airline and FAA regulations define lithium battery limits?

FAA and airline regulations limit lithium metal batteries in checked luggage to 2 grams of lithium per battery and lithium-ion batteries to 100 watt-hours per battery. Devices with batteries above these limits may require airline approval or are outright prohibited. Only two spare batteries between 101–160 Wh are allowed, and only in carry-on, with airline approval.

Why are spare lithium batteries banned from checked baggage?

Spare lithium batteries are banned from checked baggage because they present a significant fire hazard if damaged, short-circuited, or exposed to extreme conditions. In the aircraft cabin, crew and passengers can respond to overheating or smoke, but in the cargo hold, detection and mitigation are delayed, increasing the risk of uncontrolled fire.

What are the carry-on rules for lithium batteries and devices?

Lithium batteries, including power banks and spare cells, must be carried in your carry-on. Each battery should be protected from short circuits-typically by keeping them in original packaging, using a battery case, or taping over terminals. Devices with installed batteries can be carried on as well, but must be protected from accidental activation.

Which devices with lithium batteries are allowed in checked luggage?

Devices such as laptops, cameras, and tablets with lithium batteries installed can be placed in checked luggage if they are fully powered off and protected from accidental activation or damage. However, it is always safer and often recommended to keep these devices in your carry-on whenever possible.

When do international airline rules differ from US regulations?

International airlines may have stricter or slightly different rules regarding lithium batteries. While US FAA guidelines are widely followed, always check your specific airline’s policy and the regulations of your destination country before flying with lithium batteries, as some may further restrict battery size or type in checked and carry-on baggage.

How should lithium batteries be packed for air travel?

Lithium batteries should be packed to prevent damage and short circuits. Use original packaging, battery cases, or tape over terminals. In checked luggage, devices must be completely powered off. In carry-on, keep spare batteries separate and protected. Never pack damaged or recalled batteries, and do not exceed airline quantity or watt-hour limits.

Packing lithium batteries incorrectly can result in confiscation, denied boarding, fines, or even criminal penalties. More importantly, it dramatically increases the risk of fire or explosion on the aircraft. Always follow airline and FAA guidelines to ensure safety for yourself and other passengers.

Who is responsible for enforcing lithium battery airline rules?

Airlines, airport security, and the FAA are all responsible for enforcing lithium battery rules. Passengers must declare batteries and follow packing guidelines. Security may inspect and remove prohibited items. Non-compliance can result in denied boarding or legal consequences.
