AMENDMENT III to the 54th Ed. of IATA DGR: Lithium Batteries in Electronic Devices, including Medical Devices
220.127.116.11 Portable Electronic Devices (Including Medical Devices) Containing Batteries (Page 26). Summary: Portable electronic devices containing batteries when carried by passengers or crew for personal use in carry-on baggage. Spare batteries must be individually protected to prevent short circuits by placement in the original retail packaging or by otherwise insulating terminals, e.g. by taping over exposed terminals or placing each battery in a separate plastic bag or protective pouch, and carried in carry-on baggage only. Measures must also be taken to prevent unintentional activation. In addition, IATA has put limits on the lithium content or watt hours for spare batteries.
