Practical Information: Why Lithium Batteries Are Banned from Aircraft Holds

Lithium batteries, which power many mobile devices, pose a significant fire hazard if damaged or overheated. This is why their transport is subject to strict regulations, particularly in air travel. Here are the main reasons why lithium batteries are prohibited from being stored in aircraft holds:

High Fire Risk
Lithium batteries can spontaneously ignite if they experience a short circuit, overheat, or sustain physical damage. In the confined space of an aircraft hold, such a fire could spread rapidly and become uncontrollable.

Difficulty in Extinguishing Fires
Fires caused by lithium batteries are particularly challenging to extinguish as they require specialised equipment and techniques, which may not be readily available during a flight.

Safety Risks for Passengers and Crew
A fire in the aircraft hold could endanger the lives of passengers and crew and compromise the structural integrity of the plane, posing severe risks during the flight.

Rules for Transporting Lithium Batteries
To minimise these risks, strict guidelines have been established for transporting lithium batteries by air:

Spare Batteries
Spare lithium batteries are banned from aircraft holds but are permitted in the cabin under specific conditions. These include limits on the number of batteries, individual protective measures, and carrying them in hand luggage.

Electronic Devices with Batteries
It is generally allowed to carry electronic devices containing lithium batteries—such as phones and laptops—in either the cabin or the hold, provided the device is switched off and the battery is adequately protected.

High-Capacity Batteries
Batteries with a capacity exceeding 100 Wh are subject to additional restrictions. In some cases, their transport may require special authorisation from the airline.

Conclusion
Banning lithium batteries from aircraft holds is a vital safety measure aimed at preventing fires and ensuring the wellbeing of all passengers and crew on board. These regulations are a critical part of modern air travel safety protocols.
