Battery rules can depend on battery type, capacity and current carrier or aviation requirements. Use this checklist to identify what you need to verify with the relevant official authority and airline before departure.
- Battery chemistry (lithium-ion vs other)
- Watt-hour rating printed on the pack
- Whether the item is a spare / power bank vs installed in a device
- Carry-on vs checked-bag policy for that battery type
- Airline pages for the exact itinerary (origin and destination carrier rules can differ)
- Current aviation authority guidance for spare lithium batteries
