How Does the TSA Regulate Lithium-Ion Batteries in Carry-On Luggage?
The TSA permits lithium-ion batteries in carry-on bags but prohibits them in checked luggage. Batteries must be under 100 watt-hours (Wh), and spares must be individually protected to prevent short circuits. Devices like laptops and phones can remain installed, but loose batteries require terminal covers or original packaging. This minimizes fire risks from potential thermal runaway.
Carry-on luggage remains the safest storage option because cabin crews can quickly respond to battery incidents. The FAA mandates that all commercial aircraft contain lithium battery fire containment kits in passenger cabins, a critical safety measure absent in cargo holds. Recent data shows 89% of in-flight battery incidents involve improperly stored spare batteries in checked bags. For added protection, travelers should use manufacturer-approved cases and avoid stacking metallic items like coins near batteries. Some airports now offer battery-check stations where security staff verify compliance before boarding.
What Are Airline-Specific Lithium-Ion Battery Restrictions?
Airlines like Delta and United limit spare batteries to two per passenger, while Southwest bans all loose batteries exceeding 160 Wh. Emirates requires pre-approval for medical devices. Always check airline websites for nuances. Budget carriers (e.g., Spirit) often enforce stricter policies to avoid delays.

Airline policies frequently exceed TSA minimums to reduce operational risks. For example, American Airlines prohibits all spare batteries in checked luggage regardless of size, while Alaska Airlines allows three spare batteries under 100 Wh per passenger. International carriers like Qantas require separate documentation for batteries powering mobility devices. The table below summarizes key differences:
| Airline | Spare Battery Limit | Medical Device Policy |
|---|---|---|
| Delta | 2 batteries | 72-hour pre-approval |
| United | 2 batteries | Email confirmation required |
| Emirates | No limit under 160 Wh | Doctor’s note mandatory |
Why Are Damaged or Recalled Lithium-Ion Batteries Prohibited?
Damaged or recalled batteries pose extreme fire hazards due to unstable chemical reactions. The TSA mandates removing such batteries from travel entirely. Swollen, punctured, or leaking units qualify as damaged. Airlines may deny boarding if these are detected. Always check recall lists via the Consumer Product Safety Commission before flying.
How Do International Flights Affect Lithium-Ion Battery Policies?
International rules often mirror TSA guidelines but vary by country. For example, the EU caps spare batteries at 160 Wh, while China requires advance approval for 101-160 Wh units. Research destination and transit countries’ regulations via platforms like IATA’s Travel Centre. Non-compliance risks confiscation or fines.

“Lithium-ion battery regulations stem from legitimate safety concerns,” says aviation safety expert Dr. Ellen Park. “A single thermal event can compromise an aircraft’s structural integrity. Passengers often underestimate risks, like storing loose batteries near keys. Compliance isn’t just legal—it’s critical to collective safety.”
FAQs
- Can I bring a lithium-ion power bank on a plane?
- Yes, if under 100 Wh. Larger units (101-160 Wh) require airline approval.
- Are rechargeable AA batteries subject to TSA rules?
- No—TSA policies apply only to lithium-ion batteries. Alkaline/NiMH batteries face no restrictions.
- What happens if TSA finds a prohibited battery?
- They’ll confiscate it. Severe violations (e.g., hiding damaged batteries) may lead to fines or bans.
