What types of lithium batteries can be carried on an airplane?

1. The method for determining 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 according to the following methods: 1) If the nominal voltage (V) and standard of the battery are known The nominal capacity (Ah) can be calculated to obtain the value of additional watt hours: Whu003dVxAh, the nominal voltage and nominal capacity are usually marked on the battery. 2) If only the symbol on the battery has milliampere hour (mAh), divide the value 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 extra watt hours are: 760mAh/1000u003d0.76Ah; 3.7Vx0.76Ahu003d2.9Wh2. Maintenance measures for the backup lithium battery. A single backup battery is necessary. Maintain it to prevent short circuits (put it in the original retail packaging or insulate the electrodes by other means, such as sticking tape on the exposed electrodes, or put each battery in a separate plastic bag or the side of the maintenance box). 3. Lithium batteries that can be carried can be used as hand luggage to carry personal portable electronic devices such as laptops, mobile phones, cameras, watches and spare batteries containing no more than 100Wh (watt-hour) lithium batteries on board. Generally speaking, the extra energy of the lithium battery of a mobile phone is mostly 3-10Wh; the energy of the lithium battery of a SLR camera is mostly 10-20Wh; the energy of the lithium battery of a portable video camera is mostly 20-40Wh; the energy of a laptop computer's lithium battery is 30-100Wh Many vary. 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.
