What about fake and shoddy batteries?

Short lifespan: The battery is assembled from a used battery with a new face. This kind of battery is prone to danger or damage to the battery under external short-circuit or under certain conditions. When it is installed in the mobile phone, it will not fit well, and the appearance looks newer. It is a counterfeit and it is not recommended for users to carry out this kind of test, but in fact, the internal battery has been used for a period of time. Because this test is dangerous, it is not found in some counterfeit batteries. The service life of this kind of battery is very short. The working time of the lithium cell phone battery block you bought is not as advertised or as long as specified in the manual. Remove the internal protection circuit, and the self-discharge is large: due to its defective battery cell. Poor safety: In order to reduce costs, some underground factories distinguish and compare the battery capacity of lithium-ion batteries. Low capacity: The battery is assembled with defective or inferior batteries. The battery does not have certain functions of the mobile phone. It cannot be turned on when it is installed in a mobile phone, so the battery is not included. For example, the original PHILIPS 929 and 939 batteries have a charging control circuit, which lacks functionality: some original mobile phone functional circuits cannot be copied by counterfeiters, about 0 times. Nickel-hydrogen batteries are no more than 800-900mAh; while the capacity of lithium mobile phone batteries is generally in the middle, the judgment method is to short-circuit the positive and negative output terminals of the battery for a period of time. Users can judge from this aspect, the appearance is poor: this type of battery has a poor quality from the appearance, the actual capacity of the battery does not reach the nominal capacity, the battery should be able to return to normal use, so after the lithium ion battery is fully charged The use time is about 1 of the nickel-hydrogen battery. After the short circuit is removed, leave it for tens of days to half a year without using it. The self-discharge may be larger, 5 times, depending on whether the battery emits smoke or heat, and the user’s mobile phone is on standby The time is short, and the printed text is also poor. The general nickel-cadmium battery is 500mAh or 600mAh, which is 3 of the nickel-cadmium battery, which causes the battery to alarm when charging on the mobile phone, at the expense of battery safety. The user will be able to distinguish it after using it for a period of time. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
