In order to strengthen the safety of air transport of lithium batteries in passenger baggage, the Civil Aviation Administration of China (CAAC) and the Civil Aviation Administration of East China Region (CAAC-East) have successively issued the Notice on Strengthening the Safety of Lithium Batteries in Passenger Baggage for Air Transportation, requesting that the civil aviation related units further do a good job of managing the safety of transporting lithium batteries in passenger baggage, and that for the passenger baggage Lithium batteries carried in passenger baggage, in accordance with the ICAO "Technical Regulations for the Safe Transport of Dangerous Goods by Air" the following provisions:
Passengers or crew members for personal use containing lithium or lithium-ion battery cells or batteries in portable electronic devices
(lithium mobile power, watches, calculators, cameras, cell phones, laptop computers, portable video cameras, etc.) shall be carried as hand luggage on board, and the lithium content of lithium metal batteries shall not exceed 2 grams, and the rated energy value of lithium-ion batteries shall not exceed 100Wh (watt-hours). Those exceeding 100Wh but not exceeding 160Wh can be loaded on the equipment in the delivery baggage or hand baggage with the approval of the airline. Lithium batteries exceeding 160Wh are strictly prohibited.
Spare batteries for portable electronic devices must be individually protected against short-circuiting (by placing them in their original retail packaging or otherwise insulating the electrodes, e.g., taping the exposed electrodes, or placing each battery in a separate plastic bag or protective case) and may only be carried in carry-on baggage. Only two airline-approved lithium backup batteries of 100
-160Wh may be carried.
Li-ion mobile power (rechargeable batteries) equipped with an activation switch should be kept switched off during the flight. It is not permitted to use the mobile power to charge consumer electronic devices or as an external power source; it is not permitted to turn on other functions of the mobile power.
Passengers and crew members carrying wheelchairs or other similar mobility devices powered by lithium-ion batteries, and portable medical electronic devices containing lithium metal or lithium-ion battery cells or batteries carried by passengers for medical purposes, must be carried in accordance with the transportation and packaging requirements of the Technical Rules for the Safe Transportation of Dangerous Goods by Air, and must be approved by the airline.
Attachment: Tips for safe transportation of lithium batteries
I. Carriage of lithium batteries
You can bring on board laptops, cell phones, cameras, watches and other portable electronic devices for personal use and spare batteries with lithium batteries not exceeding 100Wh (watt-hours) as hand baggage.
Generally speaking, the rated energy of the lithium battery of the cell phone is 3-10Wh; the energy of the lithium battery of the DSLR camera is 10-20Wh; the energy of the lithium battery of the portable video camera is 20-40Wh; and the energy of the lithium battery of the laptop computer is 30-100Wh. Therefore, the lithium batteries in electronic devices such as cell phones, commonly used portable video cameras, DSLR cameras, and most laptops usually do not exceed the 100Wh limit.
Second, the restrictions on lithium batteries
With the approval of the airline, you can carry electronic devices containing more than 100Wh but not more than 160Wh lithium batteries on board. Each passenger can not carry more than two of these spare batteries and they cannot be checked in.
Equipment that may contain more than 100Wh lithium batteries, such as news media equipment, film and television crew equipment, performance props, medical equipment, electric toys, power tools, toolboxes, etc.
These are the most common types of lithium batteries in the world.
Prohibited lithium batteries
It is prohibited to carry or check-in large lithium batteries or electronic devices that exceed 160Wh.
Fourth, the protection of spare lithium batteries
Spare batteries must be individually protected to prevent short-circuiting (put into the original retail packaging or other ways to insulate the electrodes, such as tape on the exposed electrodes, or put each battery in a separate plastic bag or protective box).
V. Determination of the rated energy of lithium batteries
If the rated energy Wh (watt-hour) is not directly labeled on the lithium battery, the rated energy of lithium batteries can be converted in the following way:
1. If the nominal voltage (V) and nominal capacity (Ah) of the battery are known, the rated watt-hour can be obtained by calculating the following:
Wh= V x Ah
Nominal voltage and nominal capacity are usually marked on the battery.
2. If only milliampere-hour (mAh) is marked on the battery, divide the value by 1000 to get Ampere-hour (Ah).
For example, a lithium battery has a nominal voltage of 3.7V and a nominal capacity of 760 mAh, and its rated watt-hours are:
760 mAh / 1000 = 0.76Ah
3.7Vx0.76Ah=2.9Wh
