Regulatory numbers you need now: rechargeable lithium-ion cells with a rating up to 100 Wh are normally permitted in carry‑on without airline approval; cells between 100 Wh and 160 Wh require airline approval and are typically limited to two spare units; cells over 160 Wh are prohibited on passenger aircraft. Non‑rechargeable lithium metal batteries are allowed only if the lithium content does not exceed 2 g. Spare (uninstalled) lithium batteries must remain in the cabin, not in the aircraft hold.
Step‑by‑step preparation: if the battery is removable, take it out and carry it in your hand baggage. Insulate the battery terminals with tape or keep each battery in original retail packaging or in a dedicated battery pouch. Render the device powerless (remove battery, switch off, immobilize brushes) and protect it from impact with padding. Keep installed batteries at about 30% state of charge for storage and transport when possible.
How to check the battery rating and airline policy: read the label on the battery for a Wh value; if only voltage (V) and capacity in mAh are shown, calculate Wh = V × (mAh ÷ 1000). Confirm the exact policy with your airline before travel – many carriers permit devices with installed batteries only in the cabin or require batteries removed; declare the item at check‑in if requested. When in doubt, carry the appliance and any spare batteries on board in your cabin baggage and follow the airline’s lithium battery instructions.
Transporting a robotic vacuum in the aircraft hold
Yes – you may stow a robotic vacuum cleaner in the aircraft hold provided its battery complies with IATA and airline rules; removable lithium-ion cells must travel in the cabin as spare batteries.
Battery rating and limits
Locate the battery label for watt-hours (Wh) or voltage (V) and milliamp-hours (mAh). Convert using: Wh = (mAh ÷ 1000) × V. Typical models: 14.4 V × 2600 mAh ≈ 37 Wh; 14.4 V × 5200 mAh ≈ 75 Wh. Regulatory thresholds: ≤100 Wh – allowed without airline approval; 100–160 Wh – airline approval required; >160 Wh – prohibited on passenger aircraft. Spare lithium-ion batteries must be carried in the cabin, with terminals insulated.
Preparation checklist
Remove any loose batteries and place them in your carry-on; tape exposed terminals or use original battery sleeves; limit the number of spares per the carrier’s policy and declare batteries if requested. Turn the device off, disable scheduled/auto-start functions, and empty and clean the dust bin to prevent debris. Place the unit in its original box or a padded case, immobilize moving parts, and place the package centrally inside your checked bag in the aircraft hold to reduce crushing risk. Keep proof of the battery Wh rating (label photo or manual) and contact the airline at least 48 hours before departure if the battery falls into the 100–160 Wh band or if you have multiple spare cells. For international routes, verify both departure and arrival country restrictions and any airport security advisories.
Identify your robotic vacuum battery type and Wh rating (built-in vs removable)
Locate the battery’s voltage (V) and capacity (mAh) on the underside label, inside the battery bay, or in the user manual and calculate Watt-hours: Wh = V × (mAh/1000). Regulatory thresholds for passenger aircraft: Wh < 100 – normally accepted; 100 ≤ Wh ≤ 160 – requires airline approval (spare cells/packs limited and subject to airline rules); Wh > 160 – prohibited for carriage on passenger planes. Spare lithium batteries must travel in the cabin and must not be stowed in the aircraft hold.
Typical markings to look for: “Lithium‑ion” or “Li‑Po,” voltage (e.g. 14.4 V, 18 V) and capacity (e.g. 2200 mAh, 5200 mAh). Examples: 14.4 V × 2600 mAh = 14.4 × 2.6 = 37.44 Wh; 14.4 V × 5200 mAh = 14.4 × 5.2 = 74.88 Wh. If the sticker already shows Wh, use that value directly. If no label present, consult the downloadable spec sheet or manufacturer support; as a model for where specs appear in appliance pages, see are russell hobbs fridge freezers any good.
Built‑in vs removable: removable packs usually sit in a compartment with a latch, obvious connector, or quick‑release clip; built‑in packs are fixed with screws, glue or integrated into the chassis. If removable: power the device off, remove the pack, cover terminals with non‑conductive tape, place each pack in an insulated pouch, and carry them in the cabin. If non‑removable: leave the battery installed, ensure the unit is powered off, disable any auto‑start timers, and protect switches to prevent accidental activation. If capacity is unclear or exceeds 100 Wh, contact the airline in advance and retain proof of the battery rating (photo of label or manufacturer spec) before travel.
Airline and national rules for lithium batteries: when spare cells are forbidden in the aircraft hold
Do not stow spare lithium batteries in the aircraft hold – most regulators and carriers require spares to travel in the passenger cabin only.
IATA/ICAO baseline: spare lithium‑ion and lithium‑metal batteries are not permitted in the aircraft hold. Rechargeable lithium‑ion cells up to 100 Wh are normally allowed in the cabin without airline approval; cells between 100 Wh and 160 Wh require airline approval and are generally limited to two spare units per passenger; cells over 160 Wh must be shipped as cargo under UN3480/3091 with special documentation and packaging and are not accepted on passenger aircraft.
United States (TSA/DOT/PHMSA): spare lithium‑ion and lithium‑metal batteries must be carried in the cabin. European Union / EASA and UK CAA: mirror IATA – spares forbidden in the hold. Australia (CASA), Canada (Transport Canada), China (CAAC) and Japan (MLIT) apply the same cabin‑only rule; expect little regulatory variation but strict enforcement at security checkpoints and boarding.
Airline practice: most major carriers (American, Delta, United, British Airways, Lufthansa, Emirates, Qatar, Etihad, Qantas, Ryanair, easyJet and others) explicitly prohibit spare batteries from the aircraft hold in their conditions of carriage. Low‑cost and regional operators may impose tighter quantity or Wh limits; airlines require prior approval for any spare cells between 100–160 Wh and will refuse carriage without that approval.
Lithium‑metal (non‑rechargeable) batteries: cells with more than 2.0 g lithium content are not accepted on passenger aircraft (cabin or hold). Small lithium‑metal cells within the 2.0 g limit may be carried in the cabin only; larger types require cargo‑only shipment under the appropriate UN numbers and packing instructions.
Operational consequences: placing spare batteries in the hold risks immediate confiscation, denied boarding, fines or flight delays. Airlines may remove batteries at the gate or refuse carriage at check‑in if discovered. Lost or damaged batteries in the hold increase fire risk and liability exposure.
Recommended actions for travel: keep all spare cells in the cabin; insulate terminals (tape or original packaging) and separate each battery to prevent short circuits; obtain airline approval in writing for any spare cell 100–160 Wh before travelling; use cargo carriers that accept UN‑classified shipments for cells above 160 Wh and follow UN packing/labeling and the carrier’s Dangerous Goods procedures.
How to prepare and secure a removable lithium-ion battery for carry-on transport
Keep removable lithium-ion batteries in the aircraft cabin; isolate terminals with non-conductive tape, place each cell in its own protective pouch or hard case, and aim for about 30% state of charge for transit.
Follow the Wh limits: ≤100 Wh – no airline approval normally required; >100 Wh and ≤160 Wh – airline approval required and typically limited to two spare cells per passenger; >160 Wh – not permitted on passenger aircraft. Convert using Wh = V × Ah (example conversions in the table below).
Preparation steps: remove the battery from the device, inspect for damage (no dents, swelling, corrosion), clean terminals, cover exposed contacts with tape or fitted terminal caps, insert into original manufacturer sleeve or an individual insulated pouch, and place the pouch inside a rigid container or a dedicated battery case to prevent movement and contact with metal objects.
Voltage (V) | Capacity (Ah) | Watt-hours (Wh) | Cabin transport status |
---|---|---|---|
7.4 | 2.6 | 19.24 | Allowed without approval |
14.8 | 2.6 | 38.48 | Allowed without approval |
14.8 | 10.0 | 148.0 | Requires airline approval; usually max 2 spares |
22.2 | 9.0 | 199.8 | Prohibited on passenger aircraft |
Carry documentation: keep the battery’s label or manufacturer spec sheet showing Wh or V and Ah, and secure written airline approval for batteries in the 100–160 Wh range before travel. Declare the battery at check-in or the gate when approval is required.
Handling and stowage rules: do not place spare cells in the aircraft cargo hold; keep them in a carry-on bag where crew can access them if needed. Avoid metal tools or loose chargers in the same compartment; separate batteries from devices and store each in its own protective sleeve to prevent short circuits and mechanical stress.
How to secure the robot vacuum body for air transport in the aircraft hold
Place the main unit inside a rigid, hard-shell case or a purpose-made transit crate with minimum 25 mm (1 in) closed-cell foam on every contact surface; use an inner foam cradle to stop all translation and rotation of the chassis.
Power must be turned OFF and any external power connectors isolated with low-tack painter’s tape. Do not rely on the internal on/off latch alone; tape over all user-facing buttons and the charging-contact pads to prevent stray activation during baggage handling.
Empty and seal the dustbin, filter and water reservoirs in zip-lock bags (double-bag for fine dust). Store loose accessories – side brushes, main brushbar, HEPA filters, remote control – in separate padded pouches and place them adjacent to the unit so they cannot strike sensors or bumpers.
Immobilize wheels and casters using foam wedges or closed-cell blocks placed tight against the wheel circumference; avoid metal clamps or tight zip-ties that might deform axles. If axles are exposed, protect them with soft foam rolls to absorb impact.
Protect optical and lidar sensors with a thin sheet of anti-scratch material or a 3–5 mm EVA foam pad cut to fit; tape only at the foam perimeter with low-residue tape. Camera lenses should be covered with a lens protector or cling film plus a foam pad to prevent scratching.
Use at least two cross-straps (hook-and-loop or webbing with cam buckle) over the chassis to keep it pressed into the foam cradle; add a layer of polyethylene foam (25–50 mm) between the strap and shell surface to disperse concentrated pressure.
Fill all remaining voids with 25–50 mm closed-cell foam or air pillows; goal: zero movement when the case is shaken. Total foam thickness around the unit should be ≥50 mm on any side exposed to impact points.
Place the case inside your suitcase near the center of mass, surrounded by soft clothing as secondary padding, or use a dedicated flight case sized to match the unit. For case and travel gear ideas see best reclining umbrella stroller for travel and best luggage for traveling to africa.
Affix a “FRAGILE / THIS SIDE UP” label and keep a copy of the device manual and serial number in an outer pocket for inspection. If security opens the case, this speeds reassembly and documents condition on arrival.
At check-in: what to declare, required documentation and likely inspections
Declare the robotic vacuum and any lithium batteries at the check-in desk and present supporting documents before the agent accepts your item for stowage in the aircraft hold.
- What you must declare
- Device installed battery: state that the battery is contained in the equipment and provide its Wh rating.
- Spare batteries: declare number of spares, cell type (lithium‑ion or lithium metal) and individual Wh (or gram) rating.
- If a battery has been removed: show proof that it was removed and how it is being carried (in cabin or in the hold if permitted by the airline).
- Documentation to have ready
- Photocopy or photo of the battery rating label (Wh or mAh + voltage) and device model/serial number.
- Manufacturer data sheet / SDS (safety data sheet) showing chemistry and UN number: UN3480/UN3481 for lithium‑ion, UN3090/UN3091 for lithium metal.
- Purchase receipt or product manual that confirms battery capacity when the label is unclear.
- Written airline approval for batteries rated between 100–160 Wh (printed email or approval letter); without it the agent will refuse carriage.
- Government ID used for check-in and any special dangerous‑goods forms required by the carrier.
- Typical inspection steps at the counter/security
- Visual check of your documents and battery label; agent will verify Wh and removable status.
- X‑ray screening of the bag; if further checks are needed you will be asked to open the bag and remove the device for inspection.
- Physical inspection of the device: agents may require the device to be powered off, switched to storage mode, and to have battery terminals taped or insulated for demonstration.
- For removable cells: the agent may ask you to remove the cell and present it separately for inspection or to carry it in the cabin instead.
- Explosive trace detection (ETD) swabs or visual inspection of battery terminals and packaging are possible at security checkpoints.
- Likely outcomes and refusals
- If a battery exceeds 160 Wh it will usually be refused for carriage on passenger aircraft.
- Missing or insufficient documentation can result in confiscation of the battery or the entire device, delays, or denial of boarding for that item.
- If the airline’s acceptance conditions are not met (e.g., too many spares, unsecured terminals) the agent will either require corrective steps on the spot or refuse acceptance.
- Practical checklist to present at check-in
- Printed battery label photo and device model/serial.
- Manufacturer SDS and purchase receipt.
- Airline approval email when applicable (100–160 Wh).
- Battery terminals taped/insulated; device powered off and immobilized (switch taped or travel lock engaged).
- Arrive early–allow 30–60 extra minutes for dangerous‑goods screening and possible agent consultation.
