Delays in the launch of the Galileo probe to Jupiter have resulted in a new trajectory that will increase the fly-out time such that batteries will be greater than seven years old at the time of descent into the Jovian atmosphere. The longest real time data for flight design cells was five years at the time of launch. A program was initiated to establish a methodology and data base so that the performance of these cells may be predicted at the time they are expected to complete the mission. Cells from five lots and five storage temperatures, ranging from one year to seven years in age, were studied. Chemical analysis was performed on one cell from each lot/storage group. The remaining cells in each group were discharged at the mission load and temperature. Additional cells were placed on high temperature accelerated storage, and then discharged. 2 figs., 1 tab.
