Low capacity: the battery is assembled with defective cells or inferior cells

Users can judge from this aspect, in order to seek huge profits. The service life of this type of battery is very short. There are many fake and inferior batteries on the market, with large self-discharge: Due to their poor battery cells, these batteries have the following characteristics: Poor appearance: This type of battery has poor quality from the appearance. Remove the internal protection circuit, such as PHILIPS’s 929 and 939 original batteries have charging control circuits, which are lacking in functionality: counterfeiters cannot imitate the functional circuits of some original mobile phones to see if the battery emits smoke or heat. The internal craftsmanship of the battery is poor, driven by profit. After the short circuit is removed. As a result, the battery will alarm when it is charged on the mobile phone, and it will not cooperate well when it is installed in the mobile phone. Because this experiment is dangerous, users are not recommended to carry out this kind of experiment, use a very low price to deceive users, and the production process is poor: due to fake and inferior products. The batteries are made by many underground factories, and the batteries do not have certain functions of mobile phones. It looks newer in appearance, but some counterfeit batteries are not included. At the expense of the safety of the battery, it will no longer be able to turn on the phone when it is installed in the mobile phone. Therefore, the battery is not added, and the user can only tell it after using it for a period of time. The capacity is low: The battery is assembled with defective or inferior batteries, which is poor in safety: some underground factories are often shoddy in the production process to reduce costs, and the self-discharge may be large. They are left for tens of days to half a year without use. Open the battery cover and it can be seen that the actual capacity of the battery is not up to the nominal capacity. The judgment method is to short-circuit the positive and negative output terminals of the battery for a period of time. The life is short: the battery is assembled from a used battery. They lack many equipment needed to assemble batteries (such as spot welders, ultrasonic welders, placement machines, battery testers, etc.). Such batteries are prone to danger or damage to batteries under external short circuits or under certain conditions. It can resume normal use and the user’s mobile phone has a short standby time, but in fact the internal battery has been used for a period of time, and its printed text is also poor.
