NOVELTY - The label (20) has a mounting unit for mounting an electronic-paper display to a smart battery (10), and a rechargeable smart battery assembly (5) includes the label affixed to an exterior of the smart battery. A connection unit electrically connects the electronic-paper display to a smart circuitry (15) of the smart battery for determining a status of the battery on the display, where the circuitry monitors battery stains or experienced duty cycles. An ultra thin electronic status indicator (25) is integrated into the label and visually displays information provided by the circuitry.    USE - Ultra thin electronic battery label for displaying/monitoring a status e.g. experienced duty cycles, current battery capacity, current battery capacity as a percentage of rated capacity, diagnostic information and remaining lifetime on a battery, of a rechargeable smart battery in a mobile and handheld electronic devices e.g. military and public security radios, barcode scanners and personal digital assistants (PDAs), for military applications or highly mobile businesses applications for delivery workers. Can also be used for displaying safety information, certifications, manufacturer, model number and lot number, of the battery in electric cars, mobile computers, laptop computers, wireless telephones, portables defibrillators and iPods (RTM: portable media player).    ADVANTAGE - The label draws less power, and can be periodically updated with current status information. The label is always on and readable at a glance without requiring the battery to be loaded into a host electrical device/charger or analyzer and the electrical device turned on. The label is rugged and can withstand multiple drops and shock or environmental extremes, thus making the label ideal for applications. The label allows a battery pack that can be sealed to prevent water and other contaminants from entering the battery pack when the label can be in a form of a sealed adhesive assembly applied to an outside of the battery pack. The label includes an LED and/or LCD display that is updated periodically by integrating timer and updating the display at intervals, thus effectively providing user up-to-date battery status information during an entire discharge cycle of the battery.    DETAILED DESCRIPTION - The electronic status indicator is a visual cycle status indicator. AN INDEPENDENT CLAIM is also included for a method for displaying a status of a battery.
