Extensive characterization testing has been performed on a second 40 ampere hour (A h), 10 cell, bipolar nickel-hydrogen (Ni-H2) battery to study the effects of operating parameters such as charge and discharge rates, temperature, and pressure on capacity Ah and watt hour (Wh) efficiencies, end-of-charge (EOC), and mid-point discharge voltages. Testing to date has produced many interesting results, with the battery performing well throughout the test matrix except during the high-rate (5 C and 10 C) discharges, where poorer than expected results were observed. The exact cause of this poor performance is, as yet, unknown. Small scale 2 in.*2 in. battery test are to be used in studying this problem. Low earth orbit (LEO) cycle life testing at a 40% depth of discharge (DOD) and 10 degrees C is scheduled to follow the characterization testing
