This is a Battery Test Report dated 16 June 2026 for an Uninterruptible Power Supply (UPS) system located at Creech Air Force Base, Building 64.

The report documents testing results for an Eaton 93PM-L-80 UPS (Model 93PM IBS-LW) with serial number EN205UJJ05, equipped with two strings of 40 C&D UPS12-400MR batteries each (80 batteries total, 103 Ah capacity, 480 volts, dated April 2019, with 2.5 mOhms internal resistance). Battery String #1 testing results show 39 of 40 batteries passed inspection, with 3 batteries marked as failed (IDs 005, 010, 013) and 1 battery marked as warning (ID 019). Battery String #2 testing results indicate 28 of 40 batteries passed, with 8 batteries marked as failed (IDs 001, 006, 021, 022, 023, 025, 028, 030, 037, 039) and 4 batteries marked as warnings (IDs 002, 005, 013, 014, 017). The mOhm-Volts Tables provide detailed resistance and voltage readings for each battery at 83°F, with corresponding pass/fail/warning designations. Resistance Diagram and VDC Diagram charts visually represent the test data, indicating that Battery String #2 demonstrates significantly more failures and warnings than Battery String #1. Battery String #1 shows generally consistent performance with minimal critical failures, while Battery String #2 exhibits multiple voltage failures and resistance warnings distributed throughout the string, suggesting potential degradation or defects requiring further investigation or battery replacement.
