Problems solved by technology
However, even in this case, portable appliances cannot tell the difference between a battery that has not been charged many times and a battery that has been charged hundreds of times, because there is no means to accurately determine the number of times the secondary battery has been charged, and the user must remember The number of times the battery has been charged
[0010] Therefore, when the secondary battery in a portable appliance is used many times and is close to the limit of battery performance, for example, in the case of battery degradation, the degradation of the battery may be mistaken for a decrease in performance, resulting in damage to the portable appliance

Embodiment Construction
[0053] A preferred first aspect of the present invention in which a digital camera is used as the portable electric appliance described in the present invention and a battery used in the camera will be described with reference to the accompanying drawings.
[0054] image 3 is a block diagram of the digital camera 2 according to the first aspect of the present invention.
[0055] The camera 2 is a digital camera having image recording and reproducing functions. A central processing unit (CPU) 22 performs overall control over the operation of the entire camera 2 . The CPU 22 is used as a control device for controlling the camera system according to a predetermined program, and as a warning message generating device for generating a battery remaining energy warning message according to the type of the identified battery.
[0056] Programs required for various data precisely controlled by the CPU 22 are stored in a read only memory (ROM) 7 connected to the CPU 22 via a bus 34 ....

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.
Description
[0001] This patent application is a divisional application with the application number 200410030986.3, the application date is April 5, 2004, and the name is "portable electric appliance and battery". technical field [0002] The present invention relates to a portable electric appliance and a battery used therefor, and more particularly, the present invention relates to a portable electric appliance capable of using a battery as a power source and a battery capable of being used as a power source. Background technique [0003] Many portable appliances such as digital cameras can use lightweight removable batteries and readily available AA batteries. AA batteries include many kinds such as manganese batteries, alkaline batteries, and lithium batteries as primary batteries, and nickel-cadmium batteries and nickel-metal hydride batteries as secondary batteries. [0004] All of these AA batteries are the same shape as each other. Therefore, for a digital camera using AA batter...
