Carry-on details
Allowed. Ordinary alkaline (non-lithium) AA/AAA batteries are not restricted the way lithium batteries are — pack as many as you need.
Checked-bag details
Allowed. Alkaline batteries do not carry the same fire-risk restrictions as lithium batteries and may be packed in checked bags.
Special instructions
This applies to standard alkaline batteries only. Rechargeable lithium AA/AAA batteries follow the spare lithium battery rules instead.
FAQ
- Are rechargeable AA batteries treated the same as alkaline ones?
- No — if your AA/AAA batteries are rechargeable lithium-ion cells, they're treated as spare lithium batteries and must be in carry-on. Ordinary single-use alkaline batteries have no such restriction.
