Carry-on details
Allowed. Ordinary alkaline D and C batteries are dry-cell batteries, not lithium, so they carry none of the fire-risk restrictions lithium batteries do — pack as many as you need.
Checked-bag details
Allowed. Alkaline D and C batteries can be packed in checked baggage without restriction as well.
Special instructions
This applies to standard alkaline batteries only. Rechargeable lithium D/C-size batteries follow the spare lithium battery rules instead — carry-on only.
FAQ
- Are D and C batteries treated the same as AA batteries by TSA?
- Yes — standard alkaline batteries of any size (AA, AAA, C, D, 9V) have no restriction in carry-on or checked bags. Only lithium and rechargeable lithium-ion batteries carry special rules.
