The Transportation Security Administration (TSA) permits lithium batteries in carry-on bags but prohibits them in checked luggage. Passengers can bring lithium-ion batteries under 100 watt-hours (Wh) without approval, while those between 101-160 Wh require airline consent. Spare batteries must be protected from short circuits. Non-compliance may result in fines or confiscation.

How Does the TSA Regulate Lithium Batteries in Carry-On Luggage?
The TSA allows lithium batteries in carry-ons with specific guidelines: batteries must be installed in devices or individually protected to prevent short circuits. Lithium-ion batteries under 100 Wh are unrestricted, while larger ones (101-160 Wh) need airline approval. Passengers can carry up to two spare batteries. Loose batteries in checked bags are strictly prohibited due to fire risks.
What Are the Watt-Hour Limits for Lithium Batteries on Flights?
Lithium-ion batteries under 100 watt-hours (Wh) are allowed without restrictions. Those between 101-160 Wh require airline approval. Batteries exceeding 160 Wh are banned from passenger aircraft. Most consumer devices (e.g., laptops, cameras) fall under the 100 Wh limit. Check battery labels for Wh ratings or calculate them using voltage (V) × ampere-hours (Ah).

To determine watt-hours, locate the voltage (V) and ampere-hour (Ah) values printed on the battery. For example, a 12V battery rated at 5Ah equals 60Wh. Common devices like smartphones typically range from 5-20Wh, while professional cameras may reach 90Wh. Below is a reference table for popular electronics:
| Device | Typical Watt-Hours |
|---|---|
| Smartphone | 5-20Wh |
| Tablet | 30-50Wh |
| Laptop | 50-100Wh |
| DSLR Camera | 70-90Wh |
Can You Pack Spare Lithium Batteries in Checked Luggage?
No. The TSA prohibits spare lithium batteries in checked luggage due to fire hazards. All spare batteries must be in carry-ons, with terminals covered (e.g., in original packaging or taped). Installed batteries in devices are permitted in checked bags but discouraged. Airlines may impose additional restrictions, so verify policies beforehand.
How Do International Flights Handle Lithium Battery Policies?
International regulations often align with TSA but vary by country. For example, the EU follows ICAO guidelines similar to U.S. rules, while some Asian countries limit spare batteries to 20 Wh. Always check destination and airline policies. For flights with layovers, the strictest applicable rules govern battery transport.
Australia requires batteries in carry-ons to be under 160Wh with terminals insulated, while Japan prohibits loose batteries exceeding 160Wh entirely. Middle Eastern carriers like Emirates restrict spare batteries to 20Wh in checked luggage. Below is a regional comparison:
| Region | Spare Battery Limit | Checked Luggage Rules |
|---|---|---|
| European Union | 160Wh | Allowed in carry-ons only |
| Japan | 100Wh | No loose batteries |
| Australia | 160Wh | Terminal protection required |
What Precautions Should Be Taken for Damaged Lithium Batteries?
Damaged or recalled lithium batteries are prohibited on flights. If a battery is swollen, leaking, or punctured, contact the manufacturer for disposal. To transport damaged batteries for repair, obtain airline approval and pack them in fire-resistant bags. Notify TSA agents during screening to avoid delays.
Have TSA Lithium Battery Policies Changed Recently?
In 2023, the TSA clarified rules for e-bike and e-scooter batteries, limiting them to 160 Wh with airline approval. Additionally, smart luggage with non-removable batteries must be checked if the battery exceeds 100 Wh. Always review the latest TSA guidelines before traveling, as policies adapt to evolving battery technologies.
What Penalties Apply for Violating TSA Battery Rules?
Violators face fines up to $15,000 and battery confiscation. Repeat offenders may be subject to criminal charges. Airlines can deny boarding for non-compliance. The FAA also enforces penalties for in-flight battery mishandling, such as using damaged devices or charging prohibited batteries mid-flight.
Expert Views
“Lithium batteries pose unique fire risks at high altitudes,” says a former FAA safety advisor. “The TSA’s carry-on rule ensures crews can quickly contain thermal events. Passengers should treat batteries as potential hazards—store them properly and never ignore airline-specific policies. Compliance isn’t just about avoiding fines; it’s about ensuring everyone’s safety.”
Conclusion
Understanding TSA lithium battery policies is critical for safe air travel. By adhering to watt-hour limits, securing spare batteries, and staying updated on regulations, passengers can avoid penalties and contribute to in-flight safety. Always double-check airline-specific rules before packing devices or spare batteries.
FAQ
- Can I Bring a Power Bank on a Plane?
- Yes, if it’s under 100 Wh or approved by the airline (up to 160 Wh). Power banks must be in carry-ons, with terminals protected.
- Are AA Batteries Allowed on Flights?
- Standard alkaline AA batteries (non-lithium) are permitted in checked and carry-on bags. Lithium-based AA batteries follow TSA lithium rules.
- What Happens if I Accidentally Check a Lithium Battery?
- TSA may confiscate the battery and issue fines. Inform airline staff immediately if you realize the error before departure.
