Carry-on Battery Guidelines for Japan Airlines
Passengers may keep batteries and battery-powered devices in carry-on baggage to protect them from damage and temperature extremes. Lithium ion batteries up to 100 Wh and lithium metal batteries up to 2 g are generally accepted in carry-on with no extra approval. Loose batteries must be individually protected against accidental contact with metal objects. Power banks and portable chargers are only permitted in carry-on bags and must remain off during flight. Each passenger should verify capacity labels and quantity limits before reaching the gate.
Checked Baggage Battery Rules
Checked baggage is generally not permitted for lithium metal batteries, while most lithium ion batteries under 100 Wh may be carried in checked luggage with airline approval. Batteries must be securely packed so they are protected from accidental activation and contact. Spare batteries, whether lithium ion or lithium metal, should always be carried in carry-on whenever possible. If a device with an installed battery is checked, it must remain powered off and protected from damage. Unlabeled or damaged battery packs may be denied transport at check-in.
Lithium Battery Specifications and Limits
Japan Airlines applies strict specifications for lithium batteries to manage fire risks and ensure compliance with international regulations. Travelers should confirm the watt-hour rating marked on each battery and avoid carrying units above the permitted threshold. Devices with non-removable batteries may be checked only when powered off and protected from damage. External power banks must never exceed 100 Wh and must be declared if required. Documentation for medical batteries or specialized equipment should be available upon request.
Device Usage and Inflight Operations
Passengers may use battery-powered devices such as laptops, tablets, and headphones during cruise when the cabin crew indicates it is safe. All devices must remain in airplane mode or with cellular and radio transmitters disabled unless approved for inflight use. Airlines may request that power-hungry equipment be turned off if they affect onboard systems. Recharging portable devices from seatback power sources is typically permitted, but external battery packs must stay off. Follow crew instructions and airline signage to ensure uninterrupted and safe usage.
