A method of evaluating an electrochemical cell for a metallic contaminant-caused defect. The electrochemical cell is configured for use with an implantable medical device and includes an anode, a solid cathode and a liquid electrolyte. The method includes storing the cell at an elevated temperature following assembly for accelerating corrosion of possible metallic contaminants. A parameter of the cell related to cell voltage is then measured. An evaluation is made as to whether the cell is defective based upon this measured parameter.

[ What is claimed is:] [1.]1. A method of identifying a defective electrochemical cell after assembly, said cell having an anode, a solid cathode and a liquid electrolyte, comprising the steps of:storing the cell without burn-in at an elevated temperature for a storage time;testing the cell at the end of the storage time period by measuring a parameter of the cell related to cell voltage; anddetermining whether the cell is defective based upon the measured parameter.
