Although a large number of mobile phone batteries sold in small private mobile phone stores are cheap and abundant, about half of them can't guarantee the quality, and a considerable part may be refurbished batteries. Some shops sell batteries that look cheap, but they are sold in new boxes with the cores of old batteries. The cost of fake batteries is quite low. The cost of each battery is only about that of 2.5 yuan. The wholesale price in the market is 4 yuan money, and the general retail price in the market is around 50 to 70 yuan. Some black-hearted businesses sell them as original batteries, and their profits double.
Losses caused by counterfeit batteries
First of all, it must be an economic loss. Hua 70-80 yuan bought a disguised battery, which seems to be cheaper than the original one, but in fact, the performance of this battery can't reach the nominal value at all. Insufficient standby time, fever. Wait, it's common. Moreover, the most deadly battery itself is probably a waste battery, so its life will not be long. Three months is almost useless. So JS also tells you that the battery is guaranteed for 3 months. It has caused huge economic losses to users.
The second is safety. Because the manufacturing is not done according to the standards at all, there is no quality inspection and safety measures. This kind of fake battery is easy to cause some safety problems. It is easy to generate too much heat when charging, leading to fire and spontaneous combustion. In addition, it is very likely to be recharged at any time, and it will not be used in the future. Become a real waste battery. It has become a chemical waste that pollutes the environment. Affect people's health.
But don't kill it with a stick, thinking that all non-original batteries on the market are unsafe and have poor performance. In fact, there are still many professional battery manufacturers in the market, and their products are trustworthy. Common WorldCom, Desai, TCL, etc. all have such products, which are still worth buying by the public.
Remember not to buy the so-called compatible batteries of the merchants, or the so-called original batteries of goods A and B, which may be fake. If your battery has broken down or exploded when charging, you will usually buy those brands or fake batteries. On the contrary, the original battery is rare. It is best to choose a well-known brand. At the same time, pay attention to the production date and shelf life of mobile phone batteries, and be sure to buy the recently produced batteries. For those batteries whose shelf life is indicated by codes, it is generally difficult to identify them. Ask the manufacturer clearly.
Authentic mobile phones generally have the following appearance characteristics:
Under the battery label, the secondary printing technology is used. Seen from the side under certain light, the color of the bar code part is obviously darker than other parts, and the surface feels slightly convex. The white part of the surface of the battery label is lightly scratched with a metal object, which has pencil-like traces. The handwriting of the battery label is clear, and the brightness of the anti-counterfeiting mark looks three-dimensional; The mobile phone battery you bought should be neat in appearance, free of burrs and signs of leakage, freely disassembled, smooth and comfortable. The clamping position of the battery pressing part is firm, and the battery shell of the mobile phone is made of special material, which is very firm and not easy to be damaged, so it is impossible to open the battery unit under normal circumstances; The brightness of the battery electrode is the same as that of the cell phone, and the positive and negative positions of the battery electrode are marked with "+"and "-". The spacing material between the battery charging electrodes is the same as that of the shell, but it is not integrated.
