Dry Cells and Spare Batteries
Allowed
Allowed in cabin if individually protected. Not allowed loose in checked baggage.
Quick answer
Security staff constantly pull out bags where batteries are mixed with coins, keys, or tools. When two terminals touch, heat builds up, plastic melts, and smoke followsâright inside the cabin. Simple insulation solves this.
Checked baggage is riskier because vibrations can wear through tape and no one notices until the smell of smoke reaches the cockpit. Keeping spares in the cabin gives crew the chance to intervene if something feels warm.
Treat even tiny AAA cells like regulated goods: label them, separate the old from the new, and recycle damaged ones before you travel. Officers love tidy battery cases because they signal you know the rules.
Safe packing steps
- âKeep cells in original blister packs or dedicated plastic cases.
- âTape 9V terminals individually so clips cannot touch metal zippers.
- âCarry only what you need; bulk packs suggest commercial transport and may be refused.
On the journey
- âStore the case near the top of your bag for quick declaration.
- âCheck for corrosion; customs can seize leaking cells as hazardous waste.
- âIf a battery feels hot, hand it to cabin crew immediately.

FAQ
Q. Are rechargeable NiMH cells treated like lithium?
NiMH still need insulation but have fewer restrictions. Keep them in cabin and document capacity if unusually large.
Q. Can I carry button cells for medical devices?
Yes, but store them in blister packs or tape them to cardboard so they donât get lost.
Q. What if I forget to remove batteries from checked devices?
Security may recall your bag from the belt, delaying departure. Always remove and carry spares separately.
Tips before you fly
- âď¸ Use semi-transparent battery cases so officers can count cells without opening them.
- âď¸ Label cases âchargedâ or âspentâ with masking tape to avoid mixing.
- âď¸ Recycle old cells before travel so you donât tote dead weight across continents.
