What kind of lithium batteries can be carried on a plane?

Able to carry personal portable electronic devices such as laptops, mobile phones, cameras, watches and spare batteries, and carry lithium batteries no more than 100 watt-hours. 1. The method of measuring the extra energy of the lithium battery If the extra energy Wh (watt hour) is not directly marked on the lithium battery, the extra energy of the lithium battery can be converted by the following methods: 1) If the rated voltage (V) and Rated capacity (Ah), you can calculate the value of additional watt-hours: Whu003dVxAh. The nominal voltage and nominal capacity are usually marked on the battery. 2) If the symbol on the battery is only mAh, divide by 1000 to get ampere hour (Ah). For example, the nominal voltage of the lithium battery is 3.7v, the nominal capacity is 760mAh, and the additional watt-hours are: 760mAh/1000u003d0.76ah; 3.7Vx0.76Ahu003d2.9Wh 2. Maintenance measures The backup lithium battery backup battery needs to be maintained separately To prevent short circuits (put in the original retail packaging or insulated electrodes in other ways, such as sticky tape to contact the electrodes, or put each battery in a separate plastic bag or maintenance box next to it). 3. Portable lithium batteries can be used as hand luggage to carry laptops, mobile phones, cameras, watches and other personal portable electronic devices, and their lithium batteries do not exceed 100Wh (watt hours), and they can carry spare batteries. Generally speaking, the extra energy of mobile phone lithium battery is 3~10Wh. The energy of the lithium battery in a SLR camera is 10 to 20 watt-hours. The power of the lithium battery of the camera is 20-40wh. The battery life of the laptop computer's lithium battery is between 30-100wh. Therefore, lithium batteries in electronic devices such as mobile phones, camcorders, single-lens reflex cameras, and most notebook computers usually do not exceed the upper limit of 100 watt-hours.
