The new TSA policy restricts lithium batteries above 100 watt-hours (Wh) in checked baggage. Passengers can carry smaller lithium-ion batteries (under 100 Wh) and up to two larger ones (100-160 Wh) in carry-ons, provided they’re protected from damage. Spare batteries must be in original packaging or insulated to prevent short-circuiting. These rules aim to mitigate fire risks during flights.

How Many Lithium Batteries Can You Bring on a Plane?
Travelers can carry unlimited lithium-ion batteries under 100 Wh (common in phones and laptops) in carry-ons. For larger batteries (100-160 Wh), such as those in professional cameras or medical devices, only two per passenger are permitted. All batteries must be individually protected to prevent contact with metal objects. Checked bags are prohibited from containing any loose lithium batteries.
Common devices and their typical battery capacities include:

While the TSA sets baseline rules, some airlines impose additional restrictions. For example, Alaska Airlines requires separate documentation for medical equipment batteries over 100 Wh, while JetBlue limits passengers to three spare batteries total. Always check your airline’s website before packing power banks or specialty batteries.
Why Did the TSA Update Its Lithium Battery Policy?
The update addresses increased fire hazards linked to lithium batteries, which can ignite under pressure or temperature changes. The FAA reported 131 battery-related incidents in 2022, prompting stricter carry-on rules to ensure quicker crew response. Lithium fires in cargo holds are harder to contain, making checked baggage restrictions critical for aviation safety.
Recent incidents driving policy changes include:
| Year | Incident Description |
|---|---|
| 2021 | Overheated power bank caused cabin smoke on Miami-bound flight |
| 2022 | Checked luggage fire traced to damaged laptop battery |
Lithium-ion batteries pose unique risks due to thermal runaway – a chain reaction where overheating causes rapid temperature spikes up to 900°C. Unlike traditional fires, these require specialized extinguishers. The updated policy ensures flight crews can access burning batteries within seconds rather than minutes, significantly improving containment chances.
Which Airlines Enforce Stricter Lithium Battery Rules?
Delta, United, and American Airlines limit lithium batteries to carry-ons, aligning with TSA. Emirates and Qatar Airways require pre-approval for batteries above 160 Wh. Low-cost carriers like Spirit and Ryanair prohibit spare batteries in checked luggage. Always check airline-specific policies, as some may impose additional watt-hour caps or documentation requirements for medical devices.
How Should You Pack Lithium Batteries for Air Travel?
Use original packaging or tape battery terminals to prevent short-circuiting. Place each battery in a separate plastic bag or protective case. Avoid stacking batteries, which can cause crushing. For devices with non-removable batteries (e.g., smartphones), ensure they’re powered off. TSA recommends labeling batteries with watt-hour ratings to expedite security checks.
What Are the International Regulations for Lithium Batteries?
ICAO guidelines mirror TSA’s 100-160 Wh limits, but countries like Australia and Japan require permits for batteries exceeding 100 Wh. The EU mandates that spare batteries be carried in hand luggage, while China enforces a 20-battery cap per passenger. Always declare large batteries at check-in when flying internationally to avoid confiscation.
Has the TSA Policy Changed for E-Bike or Scooter Batteries?
Yes. E-bike, e-scooter, and hoverboard batteries (often 300-500 Wh) are banned in both carry-on and checked baggage unless they’re under 160 Wh and approved by the airline. Passengers must contact carriers 72 hours before departure for exceptions. Damaged or recalled batteries are strictly prohibited, regardless of size.
Are There Penalties for Violating TSA Battery Rules?
Violators face fines up to $13,910 per battery under FAA regulations. TSA may confiscate non-compliant batteries without reimbursement. Repeat offenders risk being flagged for additional screening or denied boarding. In 2022, over 12,000 batteries were seized at U.S. airports, highlighting rigorous enforcement.
Expert Views
“Lithium battery fires are a top concern for aviation safety. The new TSA rules prioritize containment by keeping high-risk batteries in the cabin, where crews can quickly address incidents. Travelers must understand that even everyday devices pose risks if mishandled.” — Dr. Elena Torres, Aviation Safety Consultant.
Conclusion
The updated TSA lithium battery policies balance passenger convenience with critical safety needs. By adhering to watt-hour limits, packing guidelines, and airline-specific rules, travelers can avoid penalties and ensure safer skies. Always verify battery specifications and international regulations before departure.
FAQ
- Can I Bring a Portable Charger on a Plane?
- Yes, if its capacity is under 100 Wh. Portable chargers between 100-160 Wh require airline approval. Ensure it’s in your carry-on.
- What Happens If My Battery Is Confiscated?
- TSA does not compensate for confiscated batteries. You may dispose of them at designated airport areas or mail them via ground services.
- Are AAA Batteries Allowed in Checked Bags?
- Alkaline AAA batteries (non-lithium) are permitted in checked luggage. Lithium AAA batteries must be in carry-ons.
