How to identify genuine and fake mobile phone batteries?

The length of battery standby time is an important indicator of the quality of the battery. The length of the battery standby time is determined by the balance of the single rechargeable batteries constituting the battery. The real battery standby time should be basically the same as that indicated on the manual. The fake ones are only half of the mark time. Some low-quality batteries are assembled using second-hand battery cells as the core and new packaging. If the seller cannot guarantee that the standby time is consistent with the manual, you cannot buy this battery. Some sellers swear by it, in fact, they don't know the actual capacity of the battery, they just dictate it casually. Such batteries are generally manufactured with poor quality battery cells. If you find that the standby time is short after purchase, you should immediately request a return. 2. Battery capacity Battery capacity is an important reference basis for battery quality and determines the battery price to a large extent. Some fake batteries have a false battery or even no capacity mark, and some fake batteries have marks and are illegible. You can take the battery to a mobile phone repair shop to measure the current to determine the authenticity. In 2013, the mobile phone batteries that everyone used were lithium-ion batteries, with a switch device and a protection circuit. So it has a certain weight. If you buy a lithium-ion battery that is too light, it means that the battery cell capacity is insufficient, and the battery may have a problem. Generally, the weight of a 900mah lithium-ion battery cell is 35g. If the weight of a battery cell plus other equipment and battery casing is less than 35g, the battery may be fake. 3. Safety performance Mobile phone batteries are flammable and explosive materials. If there is no protective circuit inside the battery, it is extremely easy to deform, leak, or even explode. However, in order to attract consumers with low prices, some low-quality batteries have removed this circuit protection board to make greater profits. There are many such unsafe batteries on the market, and it is difficult to identify them from the appearance. It is best to choose a big brand or go to a regular shopping mall to buy. The quality of the battery depends on the protection circuit and the battery cell. In 2013, the mobile phone battery cells on the market used soft-packed cells (which are customarily called polymer cells in China, although this is not strict), and some use steel or aluminum shell cells. The former can prevent violent explosions, but there is still a risk of burning and bursting. 4. Appearance to distinguish fake and inferior batteries. The common problems are: the core components of the battery, the battery chip is of poor quality, insufficient charge, short discharge time, poor anti-destructive performance, and the marked battery capacity does not match the actual. In 2013, the market was flooded with fake and shoddy mobile phone batteries, which harmed the interests of many consumers. Genuine mobile phone batteries generally have the following appearance characteristics: the battery label adopts secondary printing technology. Under a certain light, the color of the barcode part is obviously darker than other parts when viewed from an oblique surface, and it feels slightly darker than other parts when touched by hand. Convex, many original batteries have this feature. Lightly scratch the white part on the surface of the genuine battery label with a metal object, which looks like a pencil. The battery shell is made of special materials, which is very strong and not easy to damage. Under normal circumstances, it is not easy to open the battery shell. The appearance of the battery is neat and there are no excess burrs. The outer surface has a certain roughness and feels comfortable. The inner surface feels smooth under light Fine longitudinal scratches can be seen. The battery electrodes have the same width as the cell phone batteries, and the corresponding positions under the battery electrodes are marked with +- marks. The isolation material between the battery charging electrode plates is the same as the shell material, but it is not integrated. The battery should feel comfortable and comfortable when it is installed in the mobile phone. The pressing part of the battery lock is properly and firmly locked. The battery label is clearly written and has a battery part number corresponding to the battery type. The manufacturer on the battery should have a clear outline, and the anti-counterfeiting signs should have good brightness and look three-dimensional. 5. Identification of texture There are some types of mobile phone batteries. We can identify the true and false of the battery based on whether the texture of the junction is hard or not. Press down firmly on the dome-shaped joint of the mobile phone battery, and directly feel the softness and hardness of the joint with your fingers. Normally, the texture of the junction point of the genuine mobile phone battery is relatively softer, and it also shows a certain degree of flexibility, especially when the battery is inserted into the mobile phone, it has a smooth and non-blocking, easy to insert feeling, and the elasticity is suitable. The coordination is very harmonious, and the lock is stable and reliable. On the contrary, the texture of the inferior battery is harder, and the battery is not easy to slide into the cell phone battery slot during installation. The advantage of this method is that the operation is very simple, and it is also suitable for novice users. The disadvantage is that the identification accuracy is not high, and the identification range is limited! 6. The packaging identifies each cell phone battery with superior quality. From the outside, it is neat and clean, the color and texture are very clear, and the surface shell has no scratches or damages; and the label on the battery shell should include the type , Model, capacity, positive and negative signs, standard voltage, battery manufacturer name and other parameters. In addition, there should be no scratches on the hardware contacts on the battery, and there should be no green or black mold spots. If the mobile phone battery you choose is different from the genuine mobile phone battery described above, you can basically assume that the battery you currently buy is fake. 7. Anti-counterfeiting identification Generally, genuine batteries are affixed with anti-counterfeiting signs. Consumers can log on to the official website to check whether they are genuine according to the anti-counterfeiting signs, or they can confirm through the customer service phone.
