Key Details
The following table lists all eight UN38.3 test procedures conducted on the HB3 battery pack (Model 2S2P-4000), together with the individual test result for each procedure:
| Test Procedure | UN38.3 Reference | Result |
|---|---|---|
| Altitude Simulation (高度模拟) | T.1 | ✔ Pass |
| Thermal Test (温度试验) | T.2 | ✔ Pass |
| Vibration (振动) | T.3 | ✔ Pass |
| Shock (冲击) | T.4 | ✔ Pass |
| External Short Circuit (外部短路) | T.5 | ✔ Pass |
| Impact / Crush (撞击 / 挤压) | T.6 | ✔ Pass |
| Overcharge (过充电) | T.7 | ✔ Pass |
| Forced Discharge (强制放电) | T.8 | ✔ Pass |
Overall result: All 8 tests passed. The battery pack successfully demonstrates that it does not pose an unacceptable safety risk during transport conditions including low pressure, temperature extremes, mechanical stress, short circuit, and electrical abuse.
Standards & Compliance
The testing was performed in accordance with the following standard:
- UN Manual of Tests and Criteria, Section 38.3 (UN38.3), Revision 8 — the globally recognised standard for lithium battery transport safety testing, administered under the United Nations Economic Commission for Europe (UNECE) framework for the transport of dangerous goods.
UN38.3 Revision 8 is accepted by international transport regulators including IATA (air freight), IMDG (sea freight), and ADR (road transport). Compliance with this standard is a prerequisite for shipping lithium batteries internationally and is referenced in regulations such as IATA DGR and 49 CFR (US DOT).
The test report was reviewed and authorised by Deval Qin (秦林伟), Designated Reviewer at Waltek Testing Group Co., Ltd., on 2025-10-22.

UN38.3 test reports do not carry a fixed expiry date under the standard itself; however, the report applies to the specific battery model and configuration tested. Any change to the cell chemistry, cell capacity, pack configuration, or safety circuitry may require retesting. Manufacturers and shippers should consult the applicable transport regulations to confirm ongoing validity requirements for their specific shipping modes and routes.
Frequently Asked Questions
- What is UN38.3 certification and why is it required for the HB3 battery pack?
- UN38.3 is a set of transport safety tests defined in Section 38.3 of the UN Manual of Tests and Criteria. It is required by international transport authorities (IATA, IMDG, and others) before lithium batteries can be shipped commercially by air, sea, or road. The HB3 battery pack (Model 2S2P-4000) has completed all eight prescribed tests at Waltek Testing Group and received a full Pass result, confirming it meets the requirements for international transport.
- Which edition of the UN38.3 standard was used for this test?
- The testing was conducted under Revision 8 of the UN Manual of Tests and Criteria, which is the version referenced in report WTH25D09260771B issued on 2025-10-22. Revision 8 is the current edition adopted by major transport regulatory frameworks worldwide.
- What are the key specifications of the battery pack tested?
- The battery pack is a 2S2P configuration lithium-ion pack with a rated voltage of 7.4 V, a capacity of 4000 mAh, and an energy content of 29.6 Wh. It has an almost cuboid shape and an approximate mass of 185.7 g. These specifications apply to the HB3 product model.
- Does passing UN38.3 mean the battery is safe for carry-on luggage on flights?
- UN38.3 certification is a prerequisite for air transport but does not by itself determine carry-on eligibility. Airline and IATA rules also apply quantity, watt-hour, and packaging restrictions. The HB3 battery pack is rated at 29.6 Wh, which is well below the 100 Wh threshold typically permitted for carry-on lithium-ion batteries, but passengers should always verify the latest IATA Dangerous Goods Regulations and airline-specific policies before travel.
