The backup battery must be a single well protected to prevent short circuits, and can only be carried in hand luggage. In addition, each spare battery must not exceed the following quantities: for a lithium metal or lithium alloy batteries, lithium content is not more than 2 g; for a lithium-ion battery, its mass total lithium content is not more than 8 g.
Thirdly, passengers can carry mass total lithium content of more than 8 grams but not more than 25 g of lithium ion batteries, if a single well protected to prevent short circuits, can be carried in hand luggage. Spare batteries each with 2.
Finally, other types of alternate dry-cell batteries, such as nickel-metal hydride batteries, such as short circuit-proof measures can also be carried.
Finally, quality total lithium content of more than 25 g of lithium-ion batteries should be in accordance with the air transport regulations for lithium battery (MH/T1020-2007) standard, in the form of goods shipped.
