What lithium batteries can I carry on an airplane?
671 2023-11-28
Personal portable electronic devices such as laptops, mobile phones, cameras, watches and spare batteries can be carried on the plane, with lithium-ion batteries of no more than 100 watt-hours.
Determination method:
If the additional energy Wh(watt-hours) is not directly marked on the lithium-ion battery, the additional energy of the lithium-ion battery can be converted by the following methods:
(1) If the rated voltage (V) and rated capacity (Ah) of the battery are known, the additional watt-hour value can be calculated :Wh=VxAh. The nominal voltage and nominal capacity are usually labeled on the battery.
(2) If the symbol on the battery is only mAh, divide by 1000 to get the ampere-hour (Ah).
For example, the nominal voltage of the lithium-ion battery is 3.7V, the nominal capacity is 760mAh, and the additional watt-hour is :760mAh/1000=0.76Ah; 3.7 Vx0.76 Ah = 2.9 Wh
Maintenance measures standby:
Lithium-ion batteries are necessary to be maintained separately to prevent short circuits (placed in the original retail packaging or insulated electrodes in other areas, such as adhesive tape contact electrodes, or place each battery in a separate plastic bag or maintenance box next to it).
In general, the additional energy of a mobile phone lithium-ion battery is 3~10Wh. The lithium-ion battery in a SLR camera has a power of 10 to 20 watt-hours. The lithium-ion battery power of the camera is 20-40wh. The lithium-ion battery life of a laptop is between 30-100wh. As a result, lithium-ion batteries in electronic devices such as cell phones, camcorders, single-lens reflex cameras, and most laptops generally do not exceed the 100 watt-hour limit.
