Airline policiesPRE-FLIGHT CHECKLIST · REQUIRED BY THE FAA
- Spares in your carry-on, never in checked bags
- Terminals covered: tape, a battery case or the original packaging
- Gate-checked? Take the spares out and keep them with you
Our advice: also take batteries out of cameras and lights going in checked cases, and carry them on. Then you can answer “no” when asked about lithium batteries at check-in.
Exceptions and details
- Batteries inside equipment: the FAA allows them in checked bags only if the device is fully off and can't switch on, and above 100 Wh only with airline approval. Some airlines don't allow it at all.
- Approval for batteries over 100 Wh comes from your airline, not the FAA. Ask when you book, and check your airline's own rules: they can be stricter.
- Damaged or recalled batteries can't fly.
- Converting capacity: 6,600 mAh is 6.6 Ah.
- Source: FAA PackSafe: lithium batteries. These are US rules; most other countries follow similar international (IATA) rules.
