The Latest Rules and Regulations for Carrying Lithium Batteries on Planes in the UK: A Comprehensive Guide

The demand for portable electronic devices has increased over the years, and with that, the use of lithium batteries has become ubiquitous. However, the safety concerns surrounding these batteries have resulted in several regulations governing their transportation on planes. If you are planning to travel with lithium batteries on a plane in the UK, it is essential to be aware of the latest rules and regulations to avoid any inconvenience.

This article provides a comprehensive guide to the latest rules and regulations for carrying lithium batteries on planes in the UK. We will discuss the different types of lithium batteries and their restrictions, along with the quantity of batteries allowed on planes.

Types of Lithium Batteries

There are two types of lithium batteries: lithium-ion batteries and lithium metal batteries. Lithium-ion batteries are commonly used in smartphones, laptops, and other electronic devices, while lithium metal batteries are mostly used in cameras and watches.

Restrictions on Lithium Batteries

Lithium-ion batteries have a watt-hour (Wh) rating, which determines their classification as either “small” or “large” batteries. Batteries with a watt-hour rating of less than 100Wh are considered small batteries, while those with a watt-hour rating between 100Wh and 160Wh are considered large batteries.

Small Lithium-ion Batteries

Passengers are allowed to carry small lithium-ion batteries in their carry-on baggage or on their person. However, batteries with a watt-hour rating exceeding 100Wh but not exceeding 160Wh may be carried as long as they have prior airline approval.

Large Lithium-ion Batteries

Passengers are not allowed to carry large lithium-ion batteries in their checked baggage. They may carry these batteries in their carry-on baggage or on their person, but the batteries must have a watt-hour rating of less than 160Wh.

Lithium Metal Batteries

Passengers may carry lithium metal batteries in their checked and carry-on baggage. However, lithium metal batteries must not exceed 2 grams for single cells and 8 grams for batteries with multiple cells. Batteries exceeding these limits are prohibited on planes.

Quantity of Lithium Batteries Allowed

Passengers are allowed to carry a reasonable number of spare lithium batteries for personal use. However, the number of batteries allowed may depend on the type of battery and airline policy. In general, passengers are advised to carry the minimum number of batteries required for their trip.


In conclusion, it is essential to be aware of the latest rules and regulations for carrying lithium batteries on planes in the UK. The restrictions on lithium-ion batteries vary depending on their watt-hour rating, while lithium metal batteries have weight restrictions. The quantity of batteries allowed may also depend on the airline policy. By following these regulations, passengers can ensure a safe and hassle-free travel experience.
