Airlines Update Lithium Battery Policies

Lithium-ion batteries are at the heart of modern technology, powering a wide range of devices, from smartphones and laptops to electric vehicles and solar power systems, however, when mishandled, damaged, or stored improperly, they can be susceptible to thermal runaway—a dangerous condition where excess heat builds up, potentially leading to fires, explosions, and significant safety risks. This risk is particularly concerning in aviation, where the safety of passengers and crew is essential.

In recent years, the frequency of battery-related incidents has prompted airlines to revisit their safety protocols. Thermal runaway poses serious risks, such as flight delays, cancellations, and even the grounding of entire fleets. As a result, the aviation industry has tightened regulations surrounding the use of lithium-ion batteries, particularly in devices such as power banks, to reduce the risk of fires or accidents during flights. These measures are designed to protect passenger safety while maintaining operational efficiency in air travel.

A major incident occurred on January 28, 2025, at an international airport, when an Airbus A321 experienced a serious fire on the departure runway. Investigators believe the fire was caused by a lithium-ion battery, possibly from a portable power bank or other similar device, stored in the overhead luggage compartment. 

In response to these and similar incidents, several airlines in Asia have implemented stricter guidelines regarding the transportation of lithium-ion batteries. While power banks can still be carried in hand luggage, they are prohibited from charging or using them during flight. Additionally, effective March 1, 2025, a new regulation will prohibit the storage of power banks and e-cigarettes in the overhead luggage compartment on all flights within the jurisdiction. This regulation aims to mitigate the risk of fires and enhance public safety.

Air Busan was the first to change its policy to ban power banks from being placed in overhead bins in the passenger cabin, saying passengers should keep them with them so they can more easily detect any problems.

Singapore Airlines has announced that it will no longer allow its customers to charge portable power banks via onboard USB ports, or use power banks to charge personal devices during flights, starting April 1.

Taiwanese carrier EVA Air has announced a new ban on charging and using power banks and spare lithium batteries on flights, effective March 1.

China Airlines announced, effective March 1, that power banks and spare lithium batteries should not be used or charged during flights. It also recommended that passengers not place power banks in overhead bins.

Thai Airways has introduced a new policy effective March 15 prohibiting the use and charging of power banks and portable batteries during flights.
