Perform calendar life portion of the lot acceptance testing.

NASA/NSSC is issuing a sole‑source contract (FAR 12.102(a)) to Symmetry Resources, Inc. to perform the calendar‑life portion of the lot‑acceptance testing for commercial 18650 Li‑ion cells. The effort, performed at NASA’s Johnson Space Center, will continue testing of 50 cells from each of five designs (LG INR18650‑M36, Moli INR18650‑M35A, Moli INR18650‑P28B, Samsung INR18650‑30Q, Samsung ICR18650‑26F) under five states‑of‑charge and three temperature conditions. Annual capacity, self‑discharge, impedance, and DC‑resistance measurements must be taken for five consecutive test years (base year plus four one‑year options), with three cells per design/condition (45 cells total). Test accuracy requirements include voltage ± 2 mV (0.1 mV precision), current ± 2 mA (0.1 mA precision), time ± 10 s over 24 h (1 s precision), and temperature ± 1 °C (0.1 °C precision). Each annual cycle must produce separate spreadsheet reports for the high‑power cells and for the high‑ and moderate‑energy cells, detailing manufacturer, date code, procedures, and results, and be submitted within eight weeks of test completion. After NASA approves the data, all cells are to be shipped to a hazardous‑materials disposer. The contract (NAICS 541380) spans 5 years 6 months, with a base year and four optional extensions, and all capability statements must be submitted to Procurement Specialist Cara Craft by 15:00 CST on 30 April 2026.
