ABSTRACT:
An improved self-contained electronic device for testing storage batteries and other dc sources is disclosed. The testing device accurately performs small-signal measurements of the battery's dynamic conductance and provides for displaying either a numerical reading proportional to the battery's available power, or a qualitative assessment of the battery's condition. Special design features permit powering all active circuit elements by means of common power terminals and allow circuit implementation with medium scale integrated (MSI) circuits.
