An electronic device ensuring the polarity-correct installation of a battery includes a polarity-safe structure. The polarity-safe structure includes a fixing member located in a fixing groove and an elastic member secured in a receiving groove opposite to the fixing member. The battery cathode can be electrically coupled to the elastic member, but while the battery anode can be coupled to the fixing member, it cannot couple to the elastic member.
