Bluetooth speaker lithium battery rated energy value does not exceed 100Wh can be taken on board the aircraft.
Portable electronic devices (cameras, cell phones, laptop computers, portable video cameras, etc.) containing lithium batteries can be carried on board as hand baggage, and the rated energy value of the lithium 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., by taping the exposed electrodes, or by placing each battery in a separate plastic bag or case
) and may be carried in hand baggage only. Only two spare lithium batteries of 100-160Wh approved by the airline may be carried.
Wheelchairs or other similar mobility devices powered by lithium batteries and portable medical electronic devices containing lithium batteries carried by passengers for medical purposes must be carried in accordance with the relevant regulations and requirements and approved by the airline. Passengers may consult with the airline in advance for assistance.
According to the regulations of the Civil Aviation Administration of China (CAAC), lithium batteries carried on board must meet the relevant safety requirements, and travelers are advised to purchase lithium batteries from regular manufacturers through regular channels to avoid causing harm to themselves or others.
Expanded information:
If the lithium batteries, rechargeable treasure is not directly marked on the rated energy Wh (watt-hour), lithium batteries, rechargeable treasure rated energy can be converted in the following way:
If the lithium batteries, rechargeable treasure is known to the nominal voltage (V ) and the nominal capacity (Ah), the rated energy can be obtained through the calculation of the value of the rated energy:
Wh is the rated energy of lithium batteries, rechargeable treasure and the nominal capacity of lithium batteries and rechargeable treasure, the rated energy can be calculated by:< /p>
Wh= V x Ah
Nominal voltage and nominal capacity are usually marked on the lithium batteries, rechargeable treasure.
If only milliampere hours (mAh) are marked on lithium batteries and rechargeable batteries, you can divide the value by 1000 to get ampere hours (Ah).
For example: lithium batteries, rechargeable treasure nominal voltage is 3.7V, nominal capacity is 760 mAh , its rated energy is:
760 mAh ÷ 1000 = 0.76Ah
3.7V × 0.76Ah = 2.9Wh
