Abstract

An electronic apparatus capable of automatically identifying battery type is disclosed in the present invention. In the invention, a sensing circuit is installed on the electronic apparatus (such as personal digital assistant) such that the central processing unit (CPU) can sense a signal representing the battery type through the sensing circuit when CPU of the electronic apparatus turns on a charging circuit to conduct a charging process onto a battery. In addition, when reading a locking signal, the battery is identified as a common battery, which is not chargeable, such that the charging circuit stops charging the battery immediately. Thus, the electronic apparatus is capable of effectively avoiding the erroneous charging operation conducted onto the unchargeable battery by automatically identifying the type of batter to be charged.
