  • Electronic equipment and method for enabling plural types of batteries to be selectively used
    Patent number: 5912544
    Abstract: Electronic equipment, for enabling a plurality types of batteries to be selectively used, which is designed in such a way that discharge characteristic data of a plurality types of batteries to be used is previously stored in a memory unit, a battery including a resistor indicating the type of the battery is fitted to the electronic equipment, the type of the battery is identified on the basis of a resistance value of the resistor, the discharge characteristic data of the battery corresponding to the identified type of battery is read out from the memory unit, a battery voltage is compared with the discharge characteristic data thus read out and a remaining power of the battery is calculated to display the information relating to the remaining power thus calculated.
