OneKey Pro Wallet Passes UN38.3 Lithium Battery Safety Certification

For a flagship hardware wallet like the OneKey Pro, which integrates advanced encryption technology and a high-definition display, physical security is just as critical as digital asset protection. The battery, as the power core of the device, directly determines user safety and the product's capability for global delivery.

Recently, the core lithium-ion battery used in the OneKey Pro wallet (Model: 302265, Capacity: 530mAh) officially passed the globally recognized UN38.3 Safety Certification. This authoritative test summary, numbered ECTBE0H21C032A, was officially issued by Shenzhen ECT Testing Technology Co., Ltd. on September 16, 2025. It marks that the energy system of the OneKey Pro fully complies with the stringent standards set by the United Nations for the transport of dangerous goods.

Part 1: What is this certification and what is its core significance?

UN38.3 refers to Section 38.3 of the UN "Manual of Tests and Criteria". It is the mandatory "passport" for lithium batteries to enter the global market and is currently the internationally recognized core standard for measuring the safety of lithium batteries during transport and use.

1. Ensuring Physical Safety Under Extreme Conditions

Lithium batteries are classified as Class 9 dangerous goods. Passing the UN38.3 certification means that the design and manufacturing of the OneKey Pro battery have withstood extreme environmental tests. Whether in the low-pressure environment of high-altitude flight or subjected to severe bumps during transport, this 2.014Wh battery maintains chemical stability without leakage, fire, or disassembly, providing the most fundamental physical safety assurance for users.

2. The Cornerstone of Compliant Global Delivery

Meeting UN38.3 standards is a prerequisite for air and sea transport of electronic products. OneKey's acquisition of this certification implies that the Pro wallet complies with the IATA (International Air Transport Association) DGR regulations. This ensures that the product can be compliantly shipped worldwide, eliminating the risk of customs detention or return due to battery violations, allowing global users to receive their devices quickly and safely.

Part 2: What requirements must be met to pass this certification?

To obtain this certificate, the battery component of the OneKey Pro had to undergo eight "hellish" destructive tests, ranging from T.1 to T.8. According to the details disclosed in the report, the battery passed all of the following critical tests:

1. Environmental Adaptability Tests (T.1 - T.3)

• T.1 Altitude Simulation: Simulating the low-pressure environment of an aircraft cargo hold. The battery showed no leakage or venting after being kept under low pressure for 6 hours.
• T.2 Thermal Test: This is the toughest test for battery craftsmanship. The battery structure remained stable without thermal runaway under cycles of extreme cold and heat shocks.
• T.3 Vibration: Simulating continuous vibration during long-distance transport, ensuring that internal tabs and welding points do not break due to bumps.

2. Mechanical Strength Tests (T.4 & T.6)

• T.4 Shock: The battery withstood high-acceleration half-sine wave shocks, simulating accidental drops or collision scenarios, with results showing no disassembly or fire.
• T.6 Impact/Crush: This is the ultimate test for the battery casing and internal separator strength. Even when deformed by massive external crushing force, the battery did not experience internal short circuits leading to fire or explosion.

3. Electrical Safety Tests (T.5, T.7 & T.8)

• T.5 External Short Circuit: When the battery terminals were artificially short-circuited in a 57°C high-temperature environment, the internal protection mechanism responded immediately to cut the circuit, ensuring temperature control.
• T.7 Overcharge: Simulating extreme cases of charger malfunction outputting high voltage, the battery did not catch fire or disassemble.
• T.8 Forced Discharge: Simulating a scenario where the battery is forcibly discharged after being depleted, the battery remained safe during a 7-day observation period.

Part 3: Future Outlook

The passing of the UN38.3 certification for the OneKey Pro core battery reflects the brand's pursuit of perfection in product details and its responsibility towards users.

1. Transparent and High-Quality Supply Chain

The report explicitly lists the manufacturer as Shenzhen Tianmalili Energy Technology Co., Ltd. and the consignor as Mishi (ShenZhen) Technology Co., Ltd. OneKey insists on supply chain transparency, selecting only strictly verified mature suppliers to ensure that every battery installed in the device has traceable quality assurance.

2. Building a Comprehensive Security Barrier

From open-source code and EAL6+ chip certification to the current UN38.3 battery safety certification, OneKey is building a comprehensive security system from software to hardware, and from data to physical entities. In the future, OneKey will continue to follow the highest international standards to create top-tier hardware wallets for Web3 users that are proof against not only hackers but also accidents.
