Are batteries that are not installed in electronic devices and e-cigarettes permitted in checked baggage?

• A. Yes
• B. No
• C. Only if sealed
• D. Only if in original packaging

Answer: (B)

Batteries that aren’t installed in a device pose a significant fire threat, especially lithium-based ones. In flight, a loose or spare battery can short-circuit or be damaged during handling, potentially leading to a thermal runaway fire in the cargo hold where it’s difficult to detect and extinguish quickly. Because of that risk, spare batteries are not allowed in checked baggage. They must be carried in the cabin with terminals protected and the device powered off. E-cigarettes fall under the same precaution: they contain batteries and should be carried on board, not checked. So the correct stance is that these spare batteries cannot be placed in checked baggage.
