Battery type detection method and mobile terminal

The invention discloses a battery type detection method and a mobile terminal. A capacitor device is arranged in a battery which is selected from two types of batteries, the anode of the capacitor device is connected with one pin of the battery, and the pin is connected to a reference power supply via a current-limiting resistor which is arranged outside the battery; the reference power supply is switched on, charging is carried out for time Tc, the reference power supply is then switched off, and voltage detection is carried out on the pin of the battery after time Ts; if the voltage value is greater than a set value Vo, it is determined that the battery is the type of battery which is internally provided with the capacitor device; and otherwise, the battery is determined to be the other type of battery. The two types of batteries can be accurately identified with very low cost, the versatility is high, and the method can be applied to different types of mobile terminal platforms; and one temperature detection pin of the batteries can be used to detect both the type and the temperature of the battery.
