Abstract

Systems, methods and computer program products are described herein that can automatically determine the number of functional rechargeable batteries within an electronic device that includes a plurality of rechargeable batteries without having to open up the electronic device to inspect the batteries. In an embodiment, an external computing device or the electronic device itself determines a measure of impedance associated with the plurality of rechargeable batteries based on a first voltage level of the plurality of rechargeable batteries obtained during a discharging state thereof and a second voltage level of the plurality of rechargeable batteries obtained during a charging state thereof and then determines the number of operational rechargeable batteries within the plurality of rechargeable batteries based on the measure of impedance.
