Abstract:
1. An electronic apparatus which can use a battery different in physical properties, comprising: an executions of single reference operation setting unit which converts a battery content initially stored in said battery to a used charge amount for a single reference operation of the electronic apparatus and sets the battery content to a set number of executions of said single reference operation; an executions of single reference operation calculating unit which converts a used charge amount of said battery used by accumulated operations of the electronic apparatus to a charge amount used in said single reference operation and calculates the used charge amount of said battery as a calculated number of executions of said single reference operation of said apparatus, to convert the accumulated operations of the apparatus to said single reference operation; a detecting unit which detects one of a battery remaining content and a used battery content as a detected number of executions of said single reference operation based on the set number of executions of said single reference operation and the calculated number of executions of said single reference operation; and a displaying unit which displays the detected number of executions of said single reference operation.
