Immediate rule: carry spare lithium-ion batteries and external power packs in your hand baggage only; crew must be able to access and isolate any thermal event. Items with built-in batteries (phones, cameras, laptops) are generally allowed inside either carry-on or checked bags by some carriers, but most airlines require spares to remain in the cabin.
Watt‑hour limits: cells and battery packs under 100 Wh are accepted in cabin without airline approval. Packs between 100 Wh and 160 Wh require airline authorization and are usually limited to two per passenger. Packs over 160 Wh are not permitted on passenger aircraft except as cargo under strict dangerous‑goods procedures.
Protection and marking: terminals must be insulated (tape or original packaging), each spare must be individually protected from short circuit, and the Wh rating should be visible on the pack or cell. Power banks offered as checked baggage risk crush and heat damage; always stow them in carry-on.
Non‑rechargeable lithium metal cells containing more than 2 g of lithium are prohibited in passenger carriage; cells with ≤2 g are normally allowed in cabin. For mobility aids, e‑bikes or large battery assemblies notify the airline in advance: many carriers allow them only after battery removal, approved packaging, or as cargo with special handling.
Practical checklist: keep spares with you, switch equipment fully off, prevent accidental activation (remove batteries where feasible), tape exposed terminals, check your airline and departure/arrival country rules before travel, and request airline approval for packs 100–160 Wh or for any unusual battery systems.
Storing Battery-Powered Electronics in the Aircraft Hold
Do not stow lithium-ion battery-powered electronics in the aircraft hold; carry them in the passenger cabin whenever possible.
Regulatory limits and airline rules
Watt‑hour limits: batteries up to 100 Wh are allowed in carry‑on without airline approval. Batteries between 100–160 Wh require airline approval and are normally limited to two spare units per passenger. Batteries above 160 Wh are forbidden on passenger flights. These thresholds apply to lithium‑ion (rechargeable) cells–verify equivalent limits if the item uses lithium metal chemistry.
Spare cells and packs: loose spare batteries are prohibited from the aircraft hold and must be transported in the cabin with terminals protected. Airlines often refuse checked carriage of spare cells regardless of capacity.
Packing and handling instructions
Power equipment off and disable any wake‑up features. Insulate terminals with tape or place each battery in its original packaging or individual protective pouches to prevent short circuits. Secure items so they cannot shift and suffer crush damage.
If removal of the battery is possible, remove the pack and carry it onboard. For items containing non‑removable packs, contact the airline before travel; some carriers accept installed batteries in the hold only under specific conditions and after inspection at the check‑in desk.
Declare any batteries above 100 Wh at check‑in and obtain airline approval in writing. In the event of damage or visible swelling, do not transport the item at all.
Summary: keep battery packs in carry‑on, protect terminals, follow the 100 Wh / 100–160 Wh rules, and get airline approval for larger units.
Which battery types are permitted in the aircraft hold: lithium‑ion, lithium‑metal, NiMH
Recommendation: Keep spare lithium‑ion and lithium‑metal cells out of the aircraft hold – transport spares in the cabin with terminals insulated; NiMH packs may be stowed in the hold but terminals must be protected.
Lithium‑ion (Li‑ion, secondary): Cells or battery packs installed in equipment are commonly accepted in both cabin and hold, but spare Li‑ion batteries are forbidden in the hold. Watt‑hour (Wh) limits: up to 100 Wh – transportable in cabin without airline approval; >100 Wh up to 160 Wh – airline approval required and quantity limits apply (typically two spare packs per passenger); >160 Wh – not permitted on passenger aircraft. Always read the Wh marking on the pack (or calculate Wh = V × Ah) and carry evidence of the rating.
Lithium‑metal (primary): Primary lithium cells installed in equipment may be accepted depending on carrier policy, but spare lithium‑metal batteries must travel in the cabin only. Many common consumer primary batteries meet airline size limits when installed, yet some high‑capacity specialty primary cells exceed permitted lithium content and require special handling or are prohibited. Check the cell’s lithium content marking and airline rules before transport.
NiMH (nickel‑metal hydride, secondary): NiMH cells and packs are not classified under the lithium dangerous‑goods rules and are generally allowed in both cabin and the hold, including spares. Best practice: keep them in original packaging or tape terminals, avoid loose contact with metal, and limit stored charge for long trips to reduce leakage risk.
Packing checklist: identify chemistry and rating (Wh or lithium content), insulate terminals (tape, original packaging, or battery cases), carry spare Li‑ion and lithium‑metal only in the cabin, obtain airline approval for Li‑ion >100 Wh and ≤160 Wh, power off equipment and secure batteries installed in items, and consult the carrier’s cargo/transport policy for unusual batteries.

Watt‑hour and lithium‑content thresholds that change hold rules
Never stow cells or battery packs rated above 160 Wh in the aircraft hold – ratings >160 Wh are not permitted on passenger flights and must move as cargo under dangerous‑goods procedures.
Lithium‑ion (Li‑ion) thresholds: ≤100 Wh – accepted for passenger carriage without airline approval in personal equipment and as spare packs in the cabin (follow terminal protection rules); >100 Wh up to 160 Wh – airline approval required, usually limited to two spare packs per passenger and required to be carried in the cabin; >160 Wh – prohibited for passenger carriage.
Lithium‑metal thresholds: cells with lithium content ≤2 g are generally acceptable for passenger carriage when installed or carried with terminals protected; cells/batteries containing >2 g up to 8 g of elemental lithium require airline approval and are typically restricted in number and to the cabin; >8 g elemental lithium is not allowed on passenger aircraft and must be shipped as cargo under DG rules.
How to confirm ratings: use the Wh marking on the battery label. If only mAh and voltage are shown, calculate Wh = (mAh/1000) × V. For lithium‑metal, use manufacturer specifications for grams of lithium; if unavailable, treat the item as subject to approval or cargo rules.
Operational steps: check the battery label and airline policy before travel; insulate terminals (tape or original packaging), keep spare packs in carry‑on, power equipment off, declare any >100 Wh or >2 g items to the airline and obtain written approval, and arrange cargo shipment with a certified hazardous‑goods forwarder for items exceeding passenger limits.
How to prepare equipment and spare batteries for aircraft hold: insulate terminals, prevent short circuits
Recommendation: Remove all spare battery cells from electronic items, cover exposed terminals with non-conductive tape, and store each cell in an individual rigid plastic case or original packaging to eliminate risk of shorting and accidental activation.
Terminal insulation: Use high‑adhesion electrical tape (Kapton or PVC) to cover the full positive and negative ends; apply at least two overlapping wraps so no metal is exposed. For button/coin cells, tape both flat faces and the edge. For multi‑cell packs with exposed contacts, fit manufacturer caps or build a rigid non‑conductive barrier (thick plastic or nylon) so contacts cannot touch conductive material.
Containers and separation: Place each cell in a dedicated battery case or a commercial battery transport box. If using resealable plastic bags, combine them with taped terminals and place a single bagged cell per pouch; do not stack loose cells in one bag. Never use metal tins, and avoid storing batteries together with loose metal objects (coins, keys, jewelry).
Preventing activation: Power off all powered items and trigger locks or remove power switches if removable. For power banks and external battery packs: remove cables, switch the unit fully off, and cover USB/charging ports with tape or a non‑conductive cap to prevent inadvertent charging/discharging cycles.
Mechanical protection: Use a hard‑sided case, foam inserts, or rigid separators to prevent crushing and deformation during handling. For large battery packs, immobilize with foam so they cannot shift; avoid pressure on terminals or cell seams that could rupture the casing.
State of charge: Store lithium‑ion cells at roughly 30–50% state of charge for transport; very low (<5%) or fully charged (>95%) conditions increase risk during thermal events. Mark preserved charge level on packs if carrying multiple items.
Labeling and paperwork: Keep original battery documentation or specification labels accessible (Wh or lithium content). If an airline or ground crew requests inspection, present the batteries in their protective cases and show taped terminals.
Fire containment options: Place battery packs or multiple cells inside approved fire‑resistant containment pouches or hard fireproof cases when available. These do not eliminate acceptance rules but reduce propagation risk if a thermal event occurs.
Do not place loose cells or uninsulated packs in checked hold baggage; follow airline-specific transport rules for lithium cells and large capacity packs before stowing any batteries in the aircraft hold.
Handling specific items: power banks, e‑cigarettes, laptops, cameras and drones
Keep power banks and spare battery packs in carry-on only: ≥100 Wh–160 Wh units require airline approval and are normally limited to two per passenger; >160 Wh are prohibited from carriage. Always carry the manufacturer label showing Wh; unlabelled packs should be treated as high-risk and declared before boarding.
E-cigarettes and personal vaporizers must travel in the cabin, switched off, with tanks sealed or emptied. Spare batteries for these items belong in carry-on; use of these products on the aircraft is forbidden and may result in confiscation or fines.
Place laptops and cameras in carry-on where they remain accessible for screening. Remove external battery grips or hot-swappable packs and carry those in the cabin. For large integrated battery grips rated between 100 Wh and 160 Wh secure airline approval in advance. Protect fragile gear in a padded compartment and immobilize lenses and stabilizers against movement.
For drones: remove all lithium packs and transport them in the cabin with terminals insulated. Each battery must be clearly marked with Wh rating; for packs over 160 Wh transportation is not allowed. If the airframe is transported in the aircraft hold, ensure battery bays are empty and props are secured to prevent rotation or accidental activation.

To test or inflate protective inflatable gear (pads, landing pads) before travel use guidance like how to inflate an inflatable pool using an air compressor.
Airport screening outcomes and steps if a battery is discovered or confiscated
Immediately inform security staff if a battery is detected during screening and request a written incident receipt that names the officer, time, location, and specific reason for seizure.
Typical screening outcomes
- Allowed in cabin with conditions: terminals taped or insulated, device powered off, item placed in an accessible carry-on container.
- Allowed after on‑scene mitigation: security may require removal from equipment, insulation of terminals, or temporary containment in a flame‑resistant box for transport to the gate area.
- Retained and destroyed: hazardous, damaged, or out‑of‑limit batteries are commonly disposed of on site and not returned.
- Confiscated and held by airport authorities: some airports retain items for collection by the owner or lawful representative; retrieval policies vary by terminal and jurisdiction.
- Referral to law enforcement or customs: suspicious packaging, tampering, or restricted items may trigger police or customs involvement and possible fines or prosecution under local law.
Action checklist after seizure
- Obtain documentation: get an incident report or confiscation receipt with officer name, badge/ID number, and contact details for the screening agency.
- Photograph evidence: take clear photos of the item, serial numbers, packaging, and the point where the item was discovered before surrendering any claim paperwork.
- Provide proof of specifications: present manufacturer labels, spec sheets, or purchase receipts showing watt‑hours (Wh) or lithium content if available.
- Request supervisor review: politely ask for escalation to a security supervisor or airline representative if you dispute the seizure or need clarification for travel continuation.
- Confirm disposition procedure: ask whether the item will be destroyed, retained for collection, or mailed to an address; note any timelines or filing requirements for retrieval.
- Notify the carrier and regulator: record the airline’s incident number and contact the national screening authority (for example TSA in the United States, CATSA in Canada, or the airport security office) to log the event and learn appeals or claims procedures.
- File a formal complaint within deadlines: prepare a claim packet with photos, receipts, incident report, and serial numbers; submit to the airline and the screening authority within the stated timeframe (commonly 14–30 days).
- If the item shows heat, smoke, leakage, or damage: move to a safe area, inform staff immediately, avoid handling the item, and request first‑responder assistance for hazardous materials handling.
If recovery is possible, expect identity verification, a signed release, and a specified pickup window; if authorities confirm destruction, retain all documentation for insurance claims and warranty follow‑up.
FAQ:
Can I pack my phone or laptop with rechargeable batteries in checked baggage?
Devices with built-in rechargeable lithium-ion batteries are usually permitted in checked baggage, but many airlines and regulators advise keeping them in the cabin. If you check such a device, switch it off completely and protect it from damage or accidental activation (for example, remove cases that could press buttons). Spare batteries and portable chargers are typically not allowed in checked bags and must travel in carry-on. Check your airline’s specific rules before you fly.
What are the rules for spare lithium-ion batteries and power banks?
Spare lithium-ion batteries and power banks must travel in carry-on baggage only. Capacity limits are expressed in watt-hours (Wh): batteries up to 100 Wh are normally accepted in carry-on without airline approval; batteries between 100 Wh and 160 Wh usually require airline approval and passengers are often limited to two spares in this range; batteries above 160 Wh are generally prohibited on passenger aircraft. To convert mAh to Wh, use Wh = (V × mAh) / 1000 (for typical phone cells use 3.7 V as the nominal voltage). Protect battery terminals against short circuits by keeping them in original packaging or covering the contacts with tape or placing each battery in a separate plastic bag.
Can I check an e-cigarette or vape device?
No. E-cigarettes, vaporizers and their spare batteries must be carried in the cabin and must not be placed in checked baggage. Devices should be powered off and protected from accidental activation. Airlines may confiscate items that violate their rules, and many forbid use of these products during the flight. If a device has a removable battery, carry the battery in your carry-on as described above.
How should I pack rechargeable devices to reduce fire risk and avoid problems at the airport?
Keep lithium-powered devices and all spare batteries in your carry-on so they remain accessible. Power devices off and disable features that could activate them. Remove batteries when possible and carry them separately in protective covers or original packaging. Insulate terminals with tape if batteries are loose. Place devices where they will not be crushed and avoid contact with metal objects. Check both your airline’s policy and any local rules at departure or arrival airports, and notify the airline in advance if you must travel with high-capacity batteries that may require approval.
