Safety tips when using lithium batteries during your flight.
Follow these safety tips when using lithium batteries during your flight. To prevent overheating, insert lithium-metal batteries correctly, according to the polarity marked on the battery and your electronic device. To prevent heat from building up, do not cover your device’s charger when in use. Do not let lithium batteries come into contact with metal objects, or mix with unpacked batteries, as this may cause them to short-circuit. Do not leave devices plugged into the charger for longer than necessary. Once fully charged, disconnect and turn the charger off. Do not place heavy objects on electronic devices or allow them to get wet. Do not leave lithium-ion batteries unattended while charging. Do not carry damaged or recalled batteries and equipment on-board
