There are currently 169 nickel hydrogen (NiH2) cells on test in low earth orbit (LEO) application at the Naval Surface Warfare Center, Crane Division IN. There are 10 cells in a special pulse test at Phillips Lab. These tests are designed to demonstrate cell performance in a LEO application and develop a comprehensive data base to support the performance. Along with these life cycle tests there are 10 cells in an extended storage test. The test matrix consists of 31 % and 26 % KOH cells. The 26 % KOH cells were put on test in 1993. A key goal with the current test matrix is to demonstrate whether the 26 % KOH cells have improved performance over the 31 % KOH cells. This paper describes the LEO life test results and presents current status of the cells on test. This paper will also present a preliminary evaluation of the general performance of the cells with 26 % KOH vs cells with 31 % KOH. Included will be comparisons of voltage profiles for the two cell types at identical cycle numbers. Comparisons of the cells in pulse application will be included in the paper.
