Lithium batteries can easily produce high temperatures and sparks during friction or collision. When an external transport battery ignites spontaneously, crew members and passengers can detect it and extinguish it in time.
If lithium batteries are placed in checked baggage, the baggage will be crushed and collide in the small cargo space, which can easily cause the batteries to spontaneously ignite. lithium, which poses a serious safety threat. the plane. .
Portable electronic devices for personal use such as laptops, cell phones, cameras, watches, etc., containing not more than 100 Wh (watt hours) of lithium batteries and lithium batteries spare, can be carried on board as hand luggage. .
Calculation of nominal energyale of lithium batteries
If the rated energy Wh (watt hours) is not directly indicated on the lithium battery, the rated energy of the lithium battery can be calculated as follows: Conversion:
1. If the nominal voltage (V) and nominal capacity (Ah) of the battery are known, the nominal value in watt hours can be obtained by calculation: Wh= V x Ah, the nominal voltage and nominal capacity are generally indicated on the battery .
2. If the battery is only marked in milliamp-hours (mAh), you can divide the value by 1000 to get the amp-hours (Ah)?
For example: the rated voltage of a lithium battery is 3.7V, the rated capacity is 760mAh? and its rated watt hours are: 760 mAh / 1000 = 0.76 Ah, 3.7 V × 0.76 Ah. =2.9Wh.
For the above content, please refer to Guizhou Provincial Energy Bureau - Why are energy banks selfsuitable to be carried on board but not used on planes? , Fuyang Municipal People's Government--What types of lithium batteries can be taken on a plane?
Electric shavers cannot be checked in the bag in flight. You can take them with you because lithium batteries cannot be registered.
1. In accordance with relevant regulations of the Civil Aviation Administration of China, fragile, easily damaged or perishable items are not allowed to be checked in as checked baggage or packed in checked baggage. Lithium batteries are not permitted in checked baggage or baggage. “The lithium content of lithium metal batteries that can be carried with you should not exceed 2 grams, and the rated energy value of lithium-ion batteries should not exceed 100 Wh (watt hours).
2. Beat themLithium batteries with a capacity greater than 100 Wh but not exceeding 160 Wh must be inspected and approved by security personnel before they can be transported as personal effects. Each person is only allowed to carry two lithium batteries. capacities greater than 160Wh are strictly prohibited.
3. Under normal circumstances, this can be taken with you. But if you carry an electric razor with a spare blade, this must be recorded.
4. Airlines stipulate that lithium batteries with more than 160 watt hours cannot be transported or checked. A 2,500 mAh lithium battery is equivalent to 9.25 watt hours. The lithium battery in an electric shaver is therefore much smaller. you can take it with you or save it.
