| Zusammenfassung: | The invention discloses a battery detection method which comprises the following steps: providing a test battery which comprises a first shell, a first positive electrode and a first negative electrode; providing a reference voltage range, measuring the detection voltage between the first positive electrode of the tested battery and the first shell, and determining that the battery is normal if the detection voltage is within the reference voltage range; wherein the reference voltage range is obtained by the following steps: providing a reference battery, and measuring the voltage between a first positive electrode of the reference battery and a first shell to obtain V1; providing a three-electrode battery, and measuring the voltage between the second positive electrode of the three-electrode battery and the reference electrode to obtain V2; resistors with different resistance values are connected between one electrode of all the reference batteries and the first shell, and the voltage between the first posit |
