Document Overview
This article presents the UN38.3 Test Summary (Document No. S12300200858149) issued by the Shanghai Institute of Chemical Industry Testing Co., Ltd. (GHS Testing), an accredited independent test laboratory located at No. 345 East Yunling Road, Putuo, Shanghai, China 200062. The document certifies that the INR21700-50ME rechargeable lithium-ion cell complies with all applicable test requirements under the UN Manual of Tests and Criteria, ST/SG/AC.10/11/Rev.7 & Amendment 1, Section 38.3. The test report was issued on 2025-07-02 (report date recorded as 07-2025). This certification is required for the transport of lithium-ion cells and batteries by air, sea, and ground under international dangerous goods regulations, and directly supports safe global distribution of the ETENWOLF CL5 Rechargeable Camping Lantern.
Product Information

Key Details
The UN38.3 test summary covers all eight mandatory transport safety tests specified in Section 38.3 of the UN Manual of Tests and Criteria. Each test evaluates a specific stress condition that lithium cells may encounter during transport. The table below summarises every test item and its recorded result for the INR21700-50ME cell.
| Test Item | UN38.3 Clause | Test Description | Result |
|---|---|---|---|
| T.1 | 38.3.4.1 | Altitude Simulation — exposure to low-pressure environment equivalent to 15,000 m altitude | Passed |
| T.2 | 38.3.4.2 | Thermal Test — rapid thermal cycling between high and low temperature extremes | Passed |
| T.3 | 38.3.4.3 | Vibration — sinusoidal vibration across a range of frequencies simulating transport conditions | Passed |
| T.4 | 38.3.4.4 | Shock — mechanical shock pulses applied to evaluate structural integrity | Passed |
| T.5 | 38.3.4.5 | External Short Circuit — terminals shorted at elevated temperature to assess thermal response | Passed |
| T.6 | 38.3.4.6 | Impact — heavy weight dropped onto the cell to simulate crush conditions | Passed |
| T.7 | 38.3.4.7 | Overcharge — cell charged beyond rated voltage to assess safety under overcharge conditions (38.3.3(f)) | Passed |
| T.8 | 38.3.4.8 | Forced Discharge — cell discharged below zero volts to evaluate reversal safety (38.3.3(g)) | Passed |
The issuing laboratory confirmed in its remarks that the tested samples meet the requirements of test items per Manual of Tests and Criteria ST/SG/AC.10/11/Rev.7 & Amendment 1, Section 38.3. The document was signed by the Vice Chief Engineer of Shanghai Institute of Chemical Industry Testing Co., Ltd.
Standards & Compliance
The INR21700-50ME cell was tested against the following internationally recognised transport safety standard:
- UN Manual of Tests and Criteria, ST/SG/AC.10/11/Rev.7 & Amendment 1, Sub-section 38.3 — the globally accepted standard governing transport testing of lithium metal and lithium-ion cells and batteries. Compliance with this standard is mandatory for shipment under IATA Dangerous Goods Regulations (air), IMDG Code (sea), and ADR/RID (road/rail).
All eight test items (T.1 through T.8) were executed and passed, confirming full compliance. The test was conducted on the original tested cell type; results are directly applicable to transport declarations accompanying the ETENWOLF CL5 Rechargeable Camping Lantern and its integrated battery. The lithium content of 0.0689 g per cell falls well below the 1 g per cell threshold for lithium-ion cells, classifying the cell under UN 3480 / UN 3481 small lithium-ion cell provisions.

UN38.3 test summaries do not carry a fixed expiry date but are subject to re-testing if the cell design, chemistry, or manufacturing process is materially changed. The document remains valid for transport compliance purposes as long as the cell specification is unchanged from the tested configuration. The consignor and manufacturer are both listed as Huaian Tenpower Lithium Co., Ltd., confirming direct supply-chain traceability.
Frequently Asked Questions
- What is UN38.3 and why does it matter for the ETENWOLF CL5?
-
UN38.3 is the section of the UN Manual of Tests and Criteria that defines the safety tests lithium cells and batteries must pass before they can be legally transported by air, sea, or land. The ETENWOLF CL5 Rechargeable Camping Lantern contains an INR21700-50ME lithium-ion cell; possessing a valid UN38.3 test summary (report No. 1123060543) is a regulatory requirement for every shipment of the product worldwide.
- Which specific tests did the INR21700-50ME pass under UN38.3?
-
The cell passed all eight mandatory tests: T.1 Altitude Simulation, T.2 Thermal Test, T.3 Vibration, T.4 Shock, T.5 External Short Circuit, T.6 Impact, T.7 Overcharge, and T.8 Forced Discharge. Every result was recorded as Passed in test report No. 1123060543 issued by Shanghai Institute of Chemical Industry Testing Co., Ltd.
- What are the key electrical specifications of the INR21700-50ME cell?
-
The INR21700-50ME is a 3.6 V nominal, 4900 mAh rechargeable lithium-ion cell with an energy content of 17.64 Wh and a lithium content of 0.0689 g. It features a brown cylindrical form factor with a plastic film shell, conforming to the 21700 cell format.
- Does UN38.3 certification expire, and does the CL5 need re-testing?
-
There is no fixed expiry date for a UN38.3 test summary. However, if the cell’s design, active materials, or manufacturing process change materially, a new round of testing is required. As long as the INR21700-50ME supplied in the ETENWOLF CL5 matches the tested specification documented in report No. 1123060543, the certification remains valid for transport compliance purposes.
