Announcement on the Regulations on Carrying Lithium Batteries in the Baggage of Civil Aviation Passengers

In order to strengthen the air transportation safety of lithium batteries in passenger baggage, the Civil Aviation Administration and the Civil Aviation Administration of East China have successively issued the "Notice on Strengthening the Safety of Lithium Batteries in Passenger Baggage", requesting all relevant civil aviation units to further improve the safety of lithium batteries in passenger baggage. The management of the safe transportation of batteries, for passengers carrying lithium batteries in their luggage, shall be implemented in accordance with the following provisions of the International Civil Aviation Organization’s "Technical Rules for the Safe Air Transport of Dangerous Goods":

Passengers or crew members are personal portable electronic devices containing lithium or lithium ion battery cells or batteries for personal use

(Lithium battery mobile power supplies, watches, calculators, cameras, mobile phones, laptop computers, camcorders, etc.) should be carried on board as hand luggage, and the lithium content of lithium metal batteries must not exceed 2 grams, and the rated energy value of lithium ion batteries must not More than 100Wh (watt hour). If it exceeds 100Wh but does not exceed 160Wh, it can be installed on the device in checked baggage or hand luggage after approval by the airline. Lithium batteries exceeding 160Wh are strictly prohibited to be carried.

The backup batteries of portable electronic devices must be individually protected against short circuits (put them in the original retail packaging or insulate the electrodes by other means, such as sticking tape on the exposed electrodes, or put each battery in a separate plastic bag or protection Box) and can only be carried in hand luggage. 100 approved by the airline

-160Wh spare lithium battery can only carry two.

During the flight, the lithium battery mobile power supply (power bank) equipped with a start switch should be ensured that the switch is turned off. Do not use mobile power to charge consumer electronic devices or use it as an external power source; do not enable other functions of the mobile power.

Passengers and crew members who carry wheelchairs or other similar mobility tools driven by lithium-ion batteries and portable medical electronic devices that contain lithium metal or lithium-ion battery cells or batteries carried by passengers for medical purposes must comply with The transportation and packaging requirements of the Technical Rules for Transport shall be carried and approved by the airline.

Attachment: Tips for safe transportation of lithium batteries

1. Portable lithium battery

Personal portable electronic devices such as laptops, mobile phones, cameras, watches and spare batteries containing no more than 100Wh (watt hour) lithium batteries can be carried as hand luggage on board.

Generally speaking, the rated energy of lithium batteries for mobile phones is mostly 3-10Wh; the energy of lithium batteries for SLR cameras is mostly 10-20Wh; the energy of lithium batteries for camcorders is mostly 20-40Wh; the energy of lithium batteries for laptops is 30-100Wh Many vary. Therefore, lithium batteries in mobile phones, commonly used camcorders, single-lens reflex cameras, and most laptop computers and other electronic devices usually do not exceed the 100Wh limit.

2. Restricted Lithium Batteries

With the approval of the airline, electronic equipment containing lithium batteries exceeding 100Wh but not exceeding 160Wh can be carried on board. Each passenger cannot carry more than two such 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 production equipment, performance props, medical equipment, electric toys, electric tools, tool boxes, etc.

3. Lithium batteries that are prohibited from being carried

It is prohibited to carry or consign large lithium batteries or electronic equipment exceeding 160Wh.

4. Protective measures for spare lithium batteries

Spare batteries must be individually protected against short circuits (put them in the original retail packaging or insulate the electrodes by other means, such as sticking tape on the exposed electrodes, or putting each battery in a separate plastic bag or protective box).

5. Judgment method of rated energy of lithium battery

If the rated energy Wh (watt hour) is not directly marked on the lithium battery, the rated energy of the lithium battery can be converted as follows:

1. If the nominal voltage (V) and nominal capacity (Ah) of the battery are known, the value of the rated watt-hour can be obtained by calculation:

Wh = V x Ah

The 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: the nominal voltage of a lithium battery is 3.7V, the nominal capacity is 760 mAh, and the rated watt-hours are:

760 mAh / 1000 = 0.76Ah
