Yes, you can bring lithium batteries on a plane, but strict regulations govern their size, quantity, and packaging. Small lithium-ion batteries are allowed in carry-on luggage, while larger or spare batteries have restrictions or may require airline approval to ensure safe air travel.
What Are Lithium Batteries and Why Are They Regulated on Planes?
Lithium batteries store energy in a compact, rechargeable format but pose fire risks if damaged or improperly handled, prompting strict air travel regulations.
Lithium batteries come in many types, including lithium-ion (Li-ion) and lithium metal. Their high energy density is ideal for portable electronics but can lead to thermal runaway and fires if short-circuited or damaged. Aviation authorities such as the FAA and IATA enforce regulations to mitigate these fire hazards, especially in the confined airplane cargo hold or cabin environment. Knowing these rules is vital for safe, compliant air travel with batteries.

How Do Airlines Classify Lithium Batteries for Travel?
Batteries are classified by watt-hour (Wh) rating for rechargeable lithium-ion and lithium content for lithium metal, affecting travel permissions and restrictions.
Most airlines base lithium battery allowances on Wh capacity. Batteries under 100 Wh are generally permitted in carry-on luggage without airline notification. Batteries between 100 Wh and 160 Wh may require airline approval and are limited in quantity. Batteries over 160 Wh are usually prohibited as carry-ons and checked luggage. Lithium metal batteries are regulated by lithium content (grams), with strict caps to minimize fire risk. Understanding classification helps passengers prepare their batteries correctly.

| Battery Type | Size Limit (Wh) | Allowed in Carry-On | Allowed in Checked Baggage | Notes |
|---|---|---|---|---|
| Lithium-ion | <100 Wh | Yes | Usually no | Common in phones, laptops |
| Lithium-ion | 100-160 Wh | Airline approval required | Usually no | Larger power banks, e-bikes |
| Lithium-ion | >160 Wh | Usually prohibited | Prohibited | Industrial batteries |
| Lithium metal | <2 g lithium content | Yes | Usually no | Watches, small devices |
| Lithium metal | >2 g lithium content | Restricted | Usually prohibited | Specialized equipment |
Why Are Spare Lithium Batteries More Restricted Than Installed Ones?
Spare or loose lithium batteries are more susceptible to short circuits, which can ignite fires, leading to tighter rules for carriage.
Installed batteries in devices are less likely to cause sparks or shorts due to device protection circuits and stable physical positioning. Spare batteries, however, can contact conductive materials or other batteries in luggage, increasing fire risk. Hence, most airlines require spare lithium batteries to be carried in carry-on bags, individually protected (e.g., in original packaging or insulating tape) and never checked in. This precaution greatly reduces in-flight fire hazards.
How Should You Pack Lithium Batteries for Air Travel?
Secure terminal protection, separate batteries, and use original packaging or insulated cases to prevent short circuits and damage during transport.
Carry lithium batteries in carry-on luggage where possible to allow crew response to emergencies. Batteries should be individually wrapped or in plastic bags, preventing terminals from touching metal objects. Packing them inside devices is safest, but if carried spare, tape over terminals or use battery cases for insulation. Avoid loose batteries in checked bags due to fire risk. Label batteries clearly if requested by airline personnel.
Which Devices Containing Lithium Batteries Are Allowed on Planes?
Everyday electronics like smartphones, tablets, laptops, cameras, and electric scooters have widely accepted guidelines depending on battery size and airline policy.
Devices with lithium-ion batteries under 100 Wh such as smartphones, tablets, and laptops are permitted in both carry-on and checked baggage with certain restrictions. Larger consumer electronics, including power tools or e-bikes with bigger batteries, typically require airline approval and must often travel as carry-on or shipped separately. Always check with your airline, especially for newly purchased or non-standard devices.
What Are the Risks of Carrying Lithium Batteries on a Plane?
Potential for thermal runaway and fires due to battery damage, short-circuits, overcharging, or exposure to heat necessitates researching and abiding by airline rules.
Lithium batteries can ignite if internally damaged or improperly handled. On aircraft, such incidents can escalate quickly due to limited firefighting resources and confined spaces. Fire-resistant compartments and crew training mitigate risks but cannot eliminate them. Hence, manufacturers, airlines, and aviation safety organizations enforce tight carry and packaging rules, including quantity limits and prohibitions on damaged or recalled batteries.
When Should You Notify the Airline About Carrying Lithium Batteries?
Prior notification is required when carrying batteries between 100 Wh and 160 Wh or unusual quantities to ensure compliance with safety protocols.
Airlines may require advance notice for larger batteries or multiple spares carried onboard. This allows assessment of safety measures and compliance with country-specific regulations. Failure to declare such batteries can lead to denied boarding, penalties, or confiscation. Passengers shipping large lithium battery packs or specialized equipment should always confirm airline policies before travel.

How Can You Safely Ship Lithium Batteries by Air or Courier?
Compliance with IATA Dangerous Goods Regulations, correct packaging, labeling, and documentation are essential for legal and safe lithium battery shipment.
Lithium batteries must be packed using UN-approved packaging, labeled properly with hazard signs, and shipped with safety data sheets. Quantity limits and packing configurations depend on battery type and capacity. Airlines and couriers may have additional rules. Many choose Redway Battery for reliable, certified packs that simplify compliance and reduce shipment risks.
