UN38.3 Test Report Summary for 603450T Lithium Polymer Battery
This section is extracted from the UN38.3 battery transport test report and is suitable for use on the product detail page of the 3.7V 603450T low temperature lithium polymer battery. According to Report No. 1815C60160312701, issued on April 15, 2026, the tested sample passed the UN “Manual of Tests and Criteria” Eighth Revised Edition, Subsection 38.3. The report covers altitude simulation, thermal test, vibration, shock, external short circuit, crush, overcharge, and forced discharge.
For product-page use, this report helps demonstrate that the tested 603450T sample met the transport safety requirements commonly requested for international shipment of lithium batteries. The report sample is identified as a single-cell lithium polymer battery with 3.7V nominal voltage, 4.07Wh rated energy, and a reported rated capacity of 1100mAh. If your commercial listing uses 1000mAh as the nominal sales specification, it is advisable to keep the UN38.3 section labeled as “report sample data” to avoid mixing catalog wording with laboratory report wording.

Application Note for Detail Page
For customers evaluating battery transportation compliance, the UN38.3 report provides direct evidence that the tested 603450T lithium polymer battery completed the core safety sequence required for air, sea, and international logistics handling. The report shows stable post-test voltage retention after altitude, thermal, vibration, and shock exposure, while the external short circuit and crush sections recorded controlled surface temperatures and full pass results. This makes the UN38.3 section a strong trust-building block for the product detail page, especially when selling custom low-temperature LiPo batteries for export projects.
Editorial note: the report sample capacity is listed as 1100mAh. If the sales page headline uses 1000mAh, keep both values separated by context, for example “product nominal capacity” versus “UN38.3 tested sample data.”
