Zusammenfassung:	Described herein are techniques of characterizing electrical characteristics of a battery cell. The techniques employ a battery monitor coupled to a battery to measure voltage of the battery cell when it is in a recovery state after application of a stimulus (e.g., discharging or charging the battery). The measured voltage of the battery cell in the recovery state is then used to generate a characterization of the battery cell. The characterization may be used, for example, to match the battery cell with one or more similar battery cells to be coupled in a battery pack. In another example, the characterization may be used to verify authenticity of the battery cell.
