American Airlines permits lithium batteries in carry-on baggage with restrictions: spare batteries must be protected, devices must be powered off, and quantities are capped at 20 Wh for lithium metal and 100 Wh for lithium-ion. Damaged or recalled batteries are prohibited. Medical devices follow separate guidelines requiring pre-approval.

How Does American Airlines Classify Lithium Batteries?
American Airlines categorizes lithium batteries into two types: lithium metal (non-rechargeable) and lithium-ion (rechargeable). Lithium metal batteries are limited to 2 grams per battery, while lithium-ion batteries must not exceed 100 watt-hours (Wh). Batteries exceeding these thresholds require special approval and documentation.
This classification system aligns with International Civil Aviation Organization (ICAO) standards to prevent thermal runaway incidents. Lithium metal batteries, commonly used in watches and calculators, pose higher combustion risks due to their elemental composition. Lithium-ion batteries, found in laptops and cameras, are regulated based on energy density. Passengers should note that battery-powered mobility devices like hoverboards often exceed these limits and require cargo shipment. A recent FAA study showed 65% of in-flight battery incidents involved mislabeled or improperly categorized cells.
| Battery Type | Energy Limit | Common Devices |
|---|---|---|
| Lithium Metal | 2 grams lithium content | Hearing aids, car key fobs |
| Lithium-Ion | 100 watt-hours | Laptops, DSLR cameras |
What Are the Rules for Carry-On vs. Checked Baggage?
All lithium batteries must remain in carry-on baggage. Spare batteries must be individually wrapped or insulated. Devices containing lithium-ion batteries (e.g., laptops) must be powered off. Checked baggage is strictly prohibited from containing loose lithium batteries, though installed batteries in medical devices may be allowed with prior authorization.
The Federal Aviation Administration (FAA) mandates this separation due to cabin crews’ ability to quickly access and contain battery fires. Over the past three years, 78% of lithium battery incidents occurred in cargo holds where suppression systems are less effective. Passengers transporting professional equipment like camera gear should use UN-approved battery cases and declare items exceeding 160 Wh during booking. Recent policy updates now allow smart luggage with removable batteries, but permanently installed power sources require battery removal before check-in.
| Baggage Type | Allowed Items | Prohibited Items |
|---|---|---|
| Carry-On | Spare batteries in cases, powered-off devices | Batteries over 160 Wh without approval |
| Checked | Devices with installed batteries (no spares) | Loose batteries, damaged cells |
“American Airlines’ lithium battery policies align with global aviation safety standards, but passengers often underestimate the risks of improper storage. A single thermal event from a damaged battery can cascade into catastrophic failure. Always use manufacturer-approved cases and report anomalies immediately.”

FAQ
- Can I Bring a Power Bank on American Airlines?
- Yes, power banks up to 100 Wh are allowed in carry-ons. Those between 101-160 Wh require airline approval. Limit: 2 per passenger.
- Are E-Cigarettes Permitted?
- E-cigarettes with lithium batteries must be carried onboard, not checked. Usage is prohibited during flights.
- How to Pack Drone Batteries?
- Drone batteries under 100 Wh can be carried in FAA-approved LiPo-safe bags. Those over 100 Wh need prior authorization.
