Abstract: The present invention is a package for the sale and display of batteries having a voltage indicator integrally associated with the package. A pair of electrical contacts are associated with the voltage indicator and the contacts are so positioned on the package that they are accessible for alignment with the terminals of a battery placed therebetween. When the electrical contacts make simultaneous connection to the terminals of a battery, current flows through the voltage indicator to visually indicate the magnitude of the voltage of the battery.

Abstract: The present invention relates to an electrochemical cell (10) and an integrally related state of charge indicator. The state of charge indicator has two electrical contacts (14, 16) and a display means connected therebetween. A first contact (14) is connected to a first cell terminal (22) and a second contact (16) is unconnected to either terminal. A switch means (20) permits electrical connection of the second contact (16) to the second terminal to visually (26) indicate the condition of the battery by the display means.
