Singapore Airlines permits lithium batteries in carry-on luggage with strict watt-hour limits: 100Wh for consumer devices and 160Wh for approved medical equipment. Spare batteries must be individually protected. Batteries in checked baggage must be installed in devices. Power banks are banned in checked luggage. Non-compliance may result in baggage removal or flight restrictions.

How Does Singapore Airlines Classify Lithium Battery Types?
Singapore Airlines categorizes lithium batteries into three groups: lithium-ion (rechargeable), lithium-metal (non-rechargeable), and spare/uninstalled batteries. Devices like laptops and cameras fall under lithium-ion, while medical equipment uses lithium-metal. Spare batteries require protective packaging regardless of type. This classification determines placement rules in cabin vs checked baggage.
What Are the Watt-Hour Limits for Cabin Luggage?
Passengers may carry lithium batteries up to 100 watt-hours (Wh) without approval. Devices between 101-160Wh require airline authorization, limited to two pieces. Medical equipment exceeding 160Wh needs prior approval and special handling documentation. All watt-hour ratings must be clearly labeled on batteries or original packaging.

To calculate watt-hours, multiply voltage (V) by ampere-hours (Ah). Most smartphones range from 5-20Wh, while professional cameras average 40-80Wh. Passengers carrying devices like high-capacity photography equipment or medical ventilators must present technical specifications during check-in. Singapore Airlines uses automated systems to verify battery labels, with unmarked batteries subject to confiscation.
| Battery Type | Watt-Hour Limit | Approval Required |
|---|---|---|
| Consumer Electronics | ≤100Wh | No |
| Professional Equipment | 101-160Wh | Yes (max 2) |
| Medical Devices | ≤160Wh | Special clearance |
Where Should Spare Lithium Batteries Be Packed?
Spare batteries must be carried in cabin baggage with terminals covered using original packaging, tape, or individual plastic bags. Quantity restrictions apply: maximum 20 spare batteries total, with no more than two exceeding 160Wh. Loose batteries in checked luggage are strictly prohibited to prevent short-circuit risks.
Passengers should use manufacturer-supplied battery cases or purchase aviation-approved containers. The airline recommends separating batteries from metal objects like keys or coins using dedicated compartments. For extended trips requiring multiple spares, crew may request proof of necessity for quantities exceeding 10 units. Recent upgrades to cabin fire suppression systems allow safer transport of larger quantities, but improper packaging still constitutes a Category 1 safety violation.
| Battery Quantity | Packaging Requirement | Cabin Storage |
|---|---|---|
| 1-10 | Individual sleeves | Allowed |
| 11-20 | Hard-shell case | Crew inspection |
| 20+ | Special permit | Prior approval |
Why Are Power Banks Restricted in Checked Baggage?
Power banks pose fire risks in pressurized cargo holds. Singapore Airlines bans all external batteries in checked luggage regardless of capacity. Approved power banks under 100Wh can be carried onboard with terminal protection. Larger units up to 160Wh require pre-approval via the airline’s dangerous goods portal.
“Singapore Airlines’ policy reflects evolving ICAO standards, balancing safety with passenger needs. The 20-battery cabin limit addresses fire containment capabilities of aircraft systems. Recent changes focus on damaged battery detection – we’ve seen a 40% increase in reported incidents since 2022,” notes an IATA-certified dangerous goods specialist.
