Rising Risks: Lithium-Ion Battery Overheating on Airlines

The frequency of lithium-ion battery overheating incidents on airline flights has increased by 28% from 2019 to 2023, according to UL Standards. E-cigarettes are the most common culprits, and many incidents occur near passengers' seats. Despite regulations, many passengers place these batteries in checked luggage, increasing the risk of undetected fires.

Devices powered by lithium-ion batteries are overheating more frequently during airline flights, an alarming trend considering the potential hazards. Passengers often place these devices in checked bags that go into the cargo hold, where fires might not be detected as promptly.

A report released on Monday by UL Standards indicated that overheating incidents rose by 28% from 2019 to 2023, though such events are still relatively rare. Reports from 35 airlines pinpointed e-cigarettes as the most common devices to overheat.

The TSA prohibits e-cigarettes, chargers, and power banks powered by lithium-ion batteries in checked bags but allows them in carry-on luggage to mitigate fire risks in cargo holds. Nevertheless, 25% of surveyed passengers admitted to placing these devices in checked bags, often against federal rules.
