ABSTRACT:
A method for rapidly testing rechargeable electrochemical cells following assembly which enables the testing of cells to be carried out in a substantially uncharged condition. Cells in the assembly line are energized with a constant current pulse applied to their electrodes via the cell terminals, the current being of sufficient magnitude and duration so as to develop an increased charge voltage between the cell terminals. The charge voltage so developed during the application of the current and while the electrodes of the cell are incompletely charged is then measured and compared with a predetermined zone of acceptable values for cell performance. Preferably, the developed charge voltage is permitted to stabilize prior to measurement. In addition, measurements of open circuit voltage are taken immediately before and after application of the current pulse.
