Abstract
The invention discloses a mobile terminal, a battery identifying function calibrating device, a battery identifying system and method. The battery identifying system comprises the calibrating device and the mobile terminal. An adjustable resistor is arranged in the calibrating device. An instruction emitting module, an identifying range acquiring module and a storage module are arranged in the mobile terminal. The instruction emitting module emits a calibration instruction to the calibrating device. The adjustable resistor is set to be the upper limit value and the lower limit value of an RID resistor. By means of an identifying range acquiring module, the upper limit value and the lower limit value of the RID resistor are acquired. A first comparing value and a second comparing value are calculated and further stored in a storage module. When the mobile terminal is power on, the identifying range acquiring module acquires the resistance of the RID resistor and further calculates a third comparing value. Whether a battery is a valid one is determined by judging whether the third comparing value is between the first comparing value and the second comparing value. Automatic mobile terminal battery identifying range setting is thus achieved. The identifying precision is further improved.
