Abstract
A method and system for testing and sorting a production run of sheet-like batteries includes: testing each battery to obtain a first value of electrical energy; placing machine readable indicia on each battery corresponding to the first value; retesting each battery after passage of a period of time to obtain a second value of electrical energy; machine reading the indicia and computing the rate of decay of electrical energy for each battery as a function of the difference between said first and second values per unit time; and sorting the batteries in accordance with the computed rate of decay to separate those batteries having an acceptable rate of decay from those batteries having too great a rate of decay.
