Abstract

An electronic appliance has a data read/write section which reads information about a battery stored in a wireless tag provided in the battery, and a CPU which recognizes the read information about the battery and generates battery remaining energy warning information to be displayed on a display section according to the battery information. The battery remaining energy warning information according to the kind of the battery, the name of the manufacturer of the battery, etc., is generated and displayed to correctly and effectively inform a user of a remaining energy warning about the battery presently used.
