Alaska Airlines permits lithium batteries in carry-on bags but prohibits them in checked luggage. Devices like laptops and cameras are allowed, but spare batteries must be in original packaging or insulated. Limits include 20 spare lithium-ion batteries (under 100 watt-hours) per passenger. For safety, damaged or recalled batteries are banned. Always declare batteries at security checkpoints.
How Does Alaska Airlines Classify Lithium Batteries?
Alaska Airlines categorizes lithium batteries as either “installed in devices” or “spare.” Devices like smartphones and laptops are permitted in carry-ons, while spare batteries must follow stricter rules. Lithium-ion batteries must not exceed 100 watt-hours, and lithium metal batteries are capped at 2 grams of lithium content. All spare batteries require protective casing to prevent short-circuiting.

The distinction between lithium-ion and lithium metal batteries is critical for compliance. Lithium-ion batteries (common in electronics) are rated by watt-hours, while lithium metal batteries (often used in medical devices) are measured by lithium content. Passengers transporting camera equipment with dual battery types must separate them into different insulated cases. Alaska Airlines reserves the right to test batteries at check-in using voltage readers, and improperly labeled units may be denied boarding. Recent updates now require QR code scans for batteries exceeding 160Wh in medical devices.
| Battery Type | Maximum Allowance | Packaging Requirement |
|---|---|---|
| Lithium-Ion (Spare) | 20 units under 100Wh | Original packaging or terminal-protected case |
| Lithium Metal (Spare) | 8 grams total lithium | Sealed plastic bag with anti-static material |
What Are the Packing Rules for Lithium Batteries on Alaska Airlines?
Spare lithium batteries must be carried in carry-on luggage, placed in original retail packaging, or insulated with tape-covered terminals. Devices with installed batteries can be checked if powered off and protected from activation. Alaska Airlines prohibits loose batteries in checked bags and restricts quantities to 20 spare batteries per passenger.

Why Are Lithium Batteries Restricted on Flights?
Lithium batteries pose fire risks due to thermal runaway, a chemical reaction that can occur under pressure or high heat. The FAA restricts them to carry-ons so crew can quickly address incidents. Checked luggage’s unmonitored environment increases danger, making Alaska Airlines’ policy critical for minimizing in-flight hazards.
Thermal runaway events can reach temperatures exceeding 600°C within seconds, capable of melting aluminum aircraft components. A 2023 FAA report revealed 47% of battery-related incidents occurred in cargo holds during turbulence when devices shifted. Alaska Airlines uses infrared scanners in cargo areas to detect heat anomalies, but their effectiveness is limited compared to crew intervention in cabins. The airline partners with the University of Washington to develop ceramic battery containment sleeves, currently being tested on select routes.
“Alaska Airlines’ lithium battery policy aligns with global aviation safety standards, but passengers often underestimate the risks. A single improperly stored battery can trigger catastrophic thermal events. Our studies show 87% of travelers ignore casing requirements—a critical oversight. Always treat spare batteries like live ammunition: contain, insulate, and monitor.” — Aviation Safety Consultant, Dr. Elena Marquez
Can You Bring Power Banks on Alaska Airlines?
Power banks (portable chargers) are allowed only in carry-ons and must not exceed 100 watt-hours. Passengers can bring up to two larger power banks (101–160 watt-hours) with prior airline approval. All power banks must have intact casing and visible watt-hour ratings. Alaska Airlines bans those with damaged or unmarked labels.

FAQs
- Can I Pack a Drone Battery in Checked Luggage?
- No. Alaska Airlines requires all lithium drone batteries (even installed ones) to be in carry-ons. Spares must be under 100 watt-hours and in fireproof cases.
- Are E-Cigarettes Allowed on Alaska Airlines?
- Yes, but vaping devices must be in carry-ons, powered off, and protected from accidental activation. Spare e-cigarette batteries follow standard lithium rules.
- What If My Battery Lacks a Watt-Hour Label?
- Alaska Airlines may confiscate unlabeled batteries. Calculate watt-hours by multiplying voltage (V) by amp-hours (Ah). For example, 11.1V x 3.4Ah = 37.74 watt-hours.
