Yes, you can take lithium batteries on a plane, but there are strict regulations governing their transport to ensure safety. Lithium batteries are generally allowed only in carry-on baggage with limits on battery capacity (measured in watt-hours, Wh). Batteries must be protected against short circuits, and large, high-capacity batteries may require airline approval or are prohibited altogether.
What are the general rules for taking lithium batteries on a plane?
Passengers can carry lithium-ion batteries in their carry-on bags if the battery capacity is 100 watt-hours (Wh) or less. Batteries between 101Wh and 160Wh may be carried only with airline approval. Batteries over 160Wh are generally forbidden on passenger aircraft. Spare lithium batteries are never allowed in checked luggage but may be installed in devices carried onboard.
How do state-of-charge limits affect lithium battery air transport?
From 2025, many regulations recommend or require lithium batteries to be shipped or carried at a state-of-charge (SoC) of no more than 30% of their rated capacity during air transport. This reduces the risk of thermal runaway during the flight. For personal travel, it is advisable to ensure batteries are not fully charged when flying to meet these safety precautions.
Where should lithium batteries be packed during a flight?
Airlines and international regulations mandate that lithium batteries be carried in the passenger cabin as carry-on luggage. Checked baggage is generally prohibited for spare lithium batteries due to fire risks in cargo compartments. Batteries installed in equipment (like laptops or cameras) may be checked but must meet state-of-charge and packing requirements.
What are the key safety precautions for traveling with lithium batteries?
To reduce fire risk, battery terminals should be protected from short circuits, either by taping exposed terminals or storing batteries in individual plastic bags or cases. Batteries should be inspected for physical damage, swelling, or defects before flying. Airlines and passengers should also avoid overpacking or combining multiple high-capacity batteries that exceed regulatory limits.
How do airline policies vary for lithium batteries on planes?
While international regulations by ICAO and IATA set broad guidelines, individual airlines may impose stricter rules or additional restrictions, especially after recent lithium battery incidents. Some airlines prohibit charging of portable power banks onboard and limit the total number or capacity of batteries passengers can carry. Checking with the airline before flying is essential.

What about lithium metal batteries and other types?
Lithium metal batteries (non-rechargeable) are also regulated strictly and generally forbidden in checked luggage, with similar carry-on restrictions. Batteries embedded in medical devices or wheelchairs have special provisions but still require prior airline notification and compliance with packaging rules.
