ABSTRACT:
A method of the present invention is directed to recycling a battery that includes a plurality of lithium cells removable from one another. The battery is tested to measure internal resistance of the lithium cells to determine if the lithium cells present a predetermined level of operational capability. The lithium cells having the operational level less than the predetermined level of operational capability are replaced with new lithium cells as the battery is re-assembled. The removed lithium cells are recycled.
