Lithium batteries power countless devices, from smartphones and laptops to cameras, drones, and medical equipment. Since these batteries contain flammable electrolytes and pose potential fire risks, many travelers ask: Can you take a lithium battery on an airplane? The short answer is yes, but with restrictions. This article explains airline rules, international safety regulations, and best practices for flying with lithium batteries.
Why Lithium Batteries Are Restricted
Lithium batteries, especially lithium-ion (rechargeable) and lithium-metal (non-rechargeable), can be hazardous under certain conditions. Risks include:
-
Overheating or thermal runaway if damaged.
-
Fire hazards if short-circuited.
-
Explosion risk if exposed to high pressure or heat.
Because of these dangers, aviation authorities worldwide enforce strict guidelines on how lithium batteries may be transported.
Airline and Regulatory Rules
1. International Air Transport Association (IATA) Guidelines
Most airlines follow IATA regulations, which set global standards for carrying lithium batteries:
-
Lithium-ion batteries (rechargeable): Limited to 100Wh per battery for carry-on without airline approval. Batteries between 100Wh and 160Wh may be allowed with airline approval, but usually limited to two spares.
-
Lithium-metal batteries (non-rechargeable): Limited to 2 grams of lithium content per battery in most cases.
2. U.S. Federal Aviation Administration (FAA) Rules
-
Spare lithium batteries are not allowed in checked baggage.
-
They must be placed in carry-on bags only.
-
Devices containing installed batteries can be checked, but it’s recommended to keep them in carry-on.
3. European Union Aviation Safety Agency (EASA) Rules
Similar to FAA guidelines, the EASA requires that spare lithium batteries be carried in the cabin, with restrictions on capacity and number.
Can You Bring Lithium Batteries in Carry-On Luggage?
Yes, but with conditions:
-
Devices with batteries installed (phones, laptops, cameras) are allowed.
-
Spare lithium-ion batteries up to 100Wh are permitted in unlimited quantities for personal use.
-
Spare lithium-ion batteries between 100Wh and 160Wh (e.g., larger camera batteries, power banks, or drone batteries) usually require airline approval.
-
Batteries over 160Wh are typically prohibited for passenger transport and must be shipped as cargo.
Can You Put Lithium Batteries in Checked Luggage?
Generally, no. Spare lithium batteries are prohibited in checked luggage because fire risks are harder to manage in the cargo hold. Devices with batteries installed may be checked, but most airlines strongly recommend carrying them in the cabin.
Tips for Flying With Lithium Batteries
To travel safely and comply with airline rules, follow these best practices:
-
Keep batteries in carry-on bags whenever possible.
-
Protect terminals with tape or in original packaging to prevent short-circuits.
-
Use a protective case for spare batteries and power banks.
-
Avoid damaged or swollen batteries, as airlines may confiscate them.
-
Check your airline’s specific policies, since some carriers enforce stricter rules.
Common Devices That Contain Lithium Batteries
Examples of devices you can carry on an airplane include:
-
Smartphones and tablets
-
Laptops and ultrabooks
-
Digital cameras and drones
-
Power banks (portable chargers)
-
Medical devices (CPAP machines, infusion pumps)
Each device must comply with size and watt-hour restrictions.
Conclusion
Yes, you can take a lithium battery on an airplane, but only under strict conditions. Spare lithium batteries must always be carried in hand luggage, not checked baggage. Limits on watt-hours (100Wh–160Wh) apply, and larger batteries are generally prohibited. By following FAA, IATA, and airline-specific regulations, travelers can fly safely with their essential electronics and power packs.
