Abstract

A device (100) has a charging system (102) for supplying a source voltage and a source current to one or more battery cells (104), a timer (107), and a processor (106) for controlling functions of the charging system. The processor is programmed to charge (204) the one or more battery cells, track (250) a charge behavior of the battery cells, determine (260, 270, 280) a profile from the charge behavior, and detect (234) one or more defective battery cells according to the profile.
