What is the UN38.3 1.2m Drop Test and why is it required for the Helios J1?

The UN38.3 standard includes a 1.2-metre drop test as part of a suite of safety evaluations for lithium batteries intended for transport. For the Helios J1 Portable Automotive Jump Starter, this test verifies that the retail or shipping packaging can withstand real-world handling impacts without causing the battery to leak, short-circuit, or become a transport hazard. It is mandatory for international air, sea, and ground shipments of lithium-containing products under UN Model Regulations ST/SG/AC.10/1 Rev.22.

What were the exact test parameters for the Helios J1 drop test?

The package tested was a standard A=A corrugated carton measuring 470 × 324 × 204 mm with a gross weight of 15.4 kg, containing 12 units of the Helios J1. The drop was performed from a height of 1.2 metres in any orientation, per the requirements of UN Model Regulations ST/SG/AC.10/1 Rev.22, Special Provisions 188 and 230. The test was conducted by Waltek Testing Group on 2025-06-25.

Did the Helios J1 pass the UN38.3 1.2m drop test?

Yes. Report number WTH25D06164718B002, issued by Waltek Testing Group on 2025-07-04, confirms that the Helios J1 Portable Automotive Jump Starter packaging fully complied with all test requirements under ST/SG/AC.10/1 Rev.22. No battery damage, internal shifting, or content leakage was observed following the drop.

How long is this drop test report valid, and when would re-testing be needed?

This report does not have a fixed expiry date, but its validity is conditional on the product and packaging remaining unchanged. If the Helios J1's battery rated energy (currently 59.2 Wh), cell chemistry, rated voltage (14.8 V), packaging material, or carton dimensions are altered, a new drop test would be required to maintain compliance with UN transport regulations.

Standards & Compliance

The 1.2m Drop Test for the Helios J1 was conducted in accordance with the following internationally recognised transport safety standard:

Standard Reference	Description
ST/SG/AC.10/1 Rev.22	United Nations Recommendations on the Transport of Dangerous Goods — Model Regulations, 22nd Revised Edition
Special Provisions 188	Governs small lithium cells and batteries; sets energy thresholds and packaging conditions for safe transport

Transport test reports of this nature do not carry a fixed expiry date in the same manner as product safety certificates. However, the report remains valid as long as the product design, packaging configuration, and battery specifications remain unchanged from those tested. Any modification to the battery cell chemistry, rated energy (Wh), or outer packaging dimensions would necessitate re-testing.
