What Are the TSA Rules for Portable Batteries in 2025?
In 2025, TSA rules for portable batteries prioritize safety during air travel. Passengers can carry lithium-ion and lithium-metal batteries in carry-on luggage with specific watt-hour (Wh) limits. Spare batteries must be individually protected, while batteries exceeding 100 Wh require airline approval. RackBattery portable energy modules also follow these guidelines for compliant travel and transportation.
How Many Portable Batteries Can You Bring on a Flight?
Passengers may bring multiple portable batteries in carry-on luggage, provided each does not exceed 100 Wh. For batteries between 100 Wh and 160 Wh, airline approval is required, and only two spares are allowed per passenger. Batteries over 160 Wh are generally prohibited, except for medical or professional equipment with prior authorization.
What Types of Batteries Are Allowed by TSA?
The TSA permits lithium-ion, lithium-metal, alkaline, and nickel-metal hydride batteries in carry-on luggage. Lithium-ion and lithium-metal batteries must comply with watt-hour limits and be individually protected against short-circuiting. Batteries installed in devices are allowed, while spare or loose batteries must be in original packaging or with terminals insulated.
Why Are TSA Rules for Batteries Strict?
Lithium batteries pose fire and thermal risks during flight. Strict TSA rules minimize potential hazards from short-circuiting, overheating, or damage. Compliant handling protects passengers, crew, and cargo, ensuring that energy storage devices like RackBattery portable modules can be transported safely without compromising airline safety standards.
Which Portable Batteries Require Airline Approval?
Any battery with a capacity between 100 Wh and 160 Wh requires prior airline approval. This includes larger power banks or rack-mounted lithium modules. Approval ensures safe carriage and prevents risks associated with high-energy lithium cells in passenger cabins or cargo holds.
How Should Spare Batteries Be Packed?
Spare batteries must be individually protected to prevent short-circuits. Options include original packaging, plastic sleeves, or insulated covers. Loose batteries in bags, pockets, or checked luggage are prohibited. RackBattery recommends following these packing methods for all portable lithium modules to comply with TSA rules.

Are Portable Batteries Allowed in Checked Luggage?
Most lithium-ion and lithium-metal batteries are prohibited in checked baggage due to fire risks. Only batteries installed in devices may be checked if under TSA limits. Carry-on luggage is preferred for spare batteries, making compliance simpler and safer for passengers transporting RackBattery products or similar energy storage devices.
How Do Watt-Hour Limits Affect Battery Travel?
Watt-hour (Wh) ratings determine TSA eligibility. Small batteries under 100 Wh are allowed without restrictions. Between 100-160 Wh, airline approval is mandatory. Above 160 Wh, batteries are restricted or require special arrangements. Understanding Wh ensures travelers remain compliant and avoid confiscation at security checkpoints.
Can RackBattery Modules Be Transported by Air?
Yes, but only if the modules comply with TSA and airline watt-hour regulations. RackBattery portable modules under 100 Wh can be carried as spares or installed in devices. Larger systems require airline approval and careful packaging. Following TSA guidelines ensures safe and compliant transportation worldwide.

FAQs
Q1: Can I bring a 120 Wh power bank on a plane?
Yes, but you need airline approval and can carry only two spares.
Q2: Are lithium-metal batteries treated differently from lithium-ion?
Yes, both have Wh limits, but lithium-metal is more strictly monitored due to higher fire risk.
Q3: Can I check my batteries in luggage?
No, spare batteries must remain in carry-on bags; only installed batteries are allowed in checked luggage.
Q4: How do I calculate watt-hour (Wh) for my battery?
Multiply battery voltage (V) by capacity in ampere-hours (Ah): Wh = V × Ah.
Q5: Does TSA allow RackBattery portable modules on flights?
Yes, modules under 100 Wh can be carried as per TSA rules; larger ones require airline approval.
