The ICAO "Technical Regulations for the Safe Air Transport of Dangerous Goods" stipulates that passengers or crew members shall be personally used portable electronic devices containing lithium or lithium-ion cells or batteries (lithium battery mobile power supplies, watches, calculators, cameras, mobile phones, laptops, 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 exceed 100Wh (watt-hours). Those exceeding 100Wh but not exceeding 160Wh can be installed on the equipment in the hand luggage after approval by the airline. Lithium batteries exceeding 160Wh are strictly prohibited to be carried.
And can only be carried in hand luggage. Only two spare lithium batteries of 100-160Wh approved by the airline can be carried.
During the flight, the lithium battery mobile power supply (power bank) equipped with a start switch should ensure 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 mobile power.
The International Civil Aviation Organization has always stipulated that lithium batteries must be carried on board as hand luggage; if the lithium batteries are directly placed in the luggage because the luggage space is relatively small in the cargo warehouse, it is easy to be collided or squeezed, which increases the flight delay. Security risks. The carrying environment is relatively loose and safer, and if danger occurs, it can be found and handled in time. Therefore, when traveling with lithium batteries, you must strictly abide by aviation regulations: carry lithium batteries in your carry-on or hand luggage, and cannot be checked in and the lithium content of lithium metal batteries must not exceed 2 grams.
Generally, the fixed energy of the battery is measured in Wh (watt-hour), and most of them are marked on the outside of the lithium battery.
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 notebook computers ranges from 30-100Wh. 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.
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, toolboxes, etc.
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 the battery is only marked with milliampere-hour (mAh), 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 its rated watt-hours are: 760 mAh / 1000 = 0.76Ah; 3.7Vx0.76Ah=2.9Wh
Ordinary passengers generally don't need to worry too much about this regulation, because the lithium batteries in most portable electronic devices usually do not exceed the standard. However, passengers carrying large electronic equipment or passengers consigning lithium batteries must check the capacity of lithium batteries in advance and go through procedures in accordance with regulations.
