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.
