ABSTRACT:
A method for recognizing different types of batteries in a product capable of using two or more types of batteries so as to employ the battery life efficiently. The method includes detecting the battery voltage upon connection to a load and detecting variations of the battery voltage with load variations. The discharge voltages of an alkaline battery and a nickel-cadmimum are distinguished so as to avoid premature replacement of an alkaline battery.
