⚖️ Why This Rule Exists: Aviation Cargo Fire Safety & Thermal Runaway Regulations (49 CFR § 175.10)
Lithium-ion batteries carry a risk of thermal runaway if crushed, short-circuited, or overheated. Because aircraft cargo fire suppression systems (Halon 1301) cannot reliably extinguish an uncontained lithium battery fire in the cargo hold, aviation safety regulations (FAA Pack Safe and ICAO Annex 18) require spare batteries and portable electronics to be transported in the passenger cabin where flight attendants can promptly deploy thermal containment bags.
