How to distinguish fake and inferior batteries

How to distinguish counterfeit and inferior batteries with poor appearance: This type of battery has poor quality from the appearance, will not cooperate well when installed in a mobile phone, and its printed text is also poor. Low capacity: The battery is assembled with inferior or inferior batteries. The actual capacity of the battery cannot reach the nominal capacity. The standby time of the user's mobile phone is relatively short. The user can judge from this aspect. Short life: The battery is assembled from used batteries with a new look, but the internal batteries have been used for a period of time. The life of this type of battery is very short, and the user can only tell it after using it for a period of time. . Large self-discharge: Due to its poor battery cell, self-discharge may be relatively large. If you put it aside for dozens of days to half a year without using it, then you can’t turn it on when you put it in your mobile phone. Poor safety: In order to reduce costs, some underground factories do not hesitate to sacrifice the safety of the battery and remove the internal protection circuit. This kind of battery is prone to danger or damage to the battery under external short circuit or under certain conditions. The judgment method is to short-circuit the positive and negative output terminals of the battery for a period of time to see if the battery will emit smoke or heat. After the short-circuit is removed, the battery should be able to return to normal use. Because this experiment is dangerous, users are not recommended to do this Kind of experiment. Lack of functionality: counterfeiters cannot imitate the functional circuits of some original mobile phones. Therefore, if the battery is not added, the battery does not have certain functions of the mobile phone. For example, the original PHILIPS 929 and 939 batteries have a charging control circuit, but some counterfeit batteries do not, causing the battery to alarm when charging on the phone.
