The discharge curve of a cell/battery was defined either as a set Of ordered pairs: voltage, Vt vs time, ti = ti-1 + ∆t or time, ti vs discharge voltage, Vi, where U0 > Vi > V cutoff. In addition to the experimental measured discharge curve, the cell relaxation curve needs to be monitored. The Calculated Discharge Curve Method (CDCM) was developed to improve cell/battery monitoring as well as its characterization. The CDCM may be used for type qualification, product acceptance, and periodical test during service. The Algorithm procedure was presented. The Alkaline manganese cell LR 20-VARTA load 10 Ω, at ambient temperature, was used for the CDCM demonstration. The mathematical calculations were conducted on an IBM personal computer using the Symphony software.
