Today's mobile phones are becoming more and more intelligent. A small mobile phone has a lot of energy. However, when consumers use their favorite mobile phones, the battery is the most important, but often the battery is the least powerful. Because the battery life is limited, sometimes the phone is still good, but the battery has been eliminated a lot, this time, buying a new mobile phone battery becomes a must. As a mobile phone user, how to choose the counterfeit and shoddy batteries that are flooding the market? Below, Xiaobian will give you some tips, hoping to help everyone improve their understanding of mobile phone batteries.
1. Look carefully at the security signs. For example, the word NOKIA under the sticker is hidden. Clear and flawless is the original product; dim color is a counterfeit product.
2. All genuine mobile phone batteries should be neat in appearance, without excessive burrs, the outer surface has a certain roughness and feel comfortable; the inner surface is smooth, and fine vertical scratches can be seen under the light. The battery electrode and the mobile phone battery have the same width, and the corresponding positions under the battery electrode are marked with [+], [-], and the battery charging electrode is the same as the outer casing material, but not integrated.
3. For the original battery, its battery surface color texture is clear, uniform, clean, no obvious scratches and damage; battery mark should be printed with battery type, type, rated capacity, standard voltage, positive and negative signs, manufacturer name . The hand should be smooth and non-blocking, suitable for tightness, good fit with the hand, reliable lock; the metal piece has no obvious scratches and black and green. If the cell phone battery we purchased does not match the above phenomenon, it can be preliminarily determined to be a fake.
4. At present, many mobile phone manufacturers have also made efforts to improve the level of craftsmanship to improve the difficulty of fraud in mobile phones and their accessories, thereby further curbing the phenomenon of counterfeit goods. Generally, regular mobile phone products and their accessories must be consistent in appearance. Therefore, if we put the purchased mobile phone battery, we should carefully compare the color of the fuselage and the battery bottom case. If the color is dark and the same, it is the original battery. Otherwise, the battery itself is dull and dull, and it may be a fake battery.
5. Observe the abnormal situation of charging. Generally, there should be an overcurrent protector inside the genuine mobile phone battery. In the case of excessive current caused by external short circuit, the circuit is automatically cut off to avoid burning or damage the mobile phone. The lithium ion battery has an overcurrent protection circuit. Standardize the electrical appliance. When the AC current is too large, the power will be automatically cut off, resulting in no charge. In normal battery condition, it can automatically return to the conduction state. If, during the charging process, we find that the battery is seriously hot or smoke, or even explode, the battery is definitely fake.
6. Compare the size of the battery capacity. The general cadmium nickel battery is 500mAh or 600mAh, and the hydrogen nickel battery is only 800-900mAh; while the lithium ion mobile phone battery is generally between 1300-1400mAh, so the lithium ion battery is fully charged and the time is about hydrogen nickel battery. 1.5 times, it is about 3.0 times that of cadmium nickel battery. If you find that the working hours of the lithium-ion mobile phone battery block you purchased are not advertised or as long as specified in the manual, it may be counterfeit.
7. Use a dedicated detector. The quality of the mobile phone battery is difficult to distinguish from the appearance. To this end, a mobile phone battery tester has been introduced on the market. The battery tester can detect and determine the capacity and quality of various batteries such as lithium and nickel with a voltage between 2.4V and 6.0V and a capacity of less than 1999mAH. And has the functions of start, charge, discharge and so on. The whole process is controlled by the microprocessor according to the battery characteristics, and the technical parameters such as voltage, current and capacity of the measured voltage can be realized.
8. When you identify the true and false batteries, you often overlook a small detail, that is, the battery contacts. Because of the various brand-name mobile phone batteries, most of their contacts are annealed, it should be matt, not shiny, so according to this point, you can preliminarily determine the authenticity of the phone battery. In addition, we must carefully observe the color of the contact lens. The touch of the fake mobile phone battery is often made of copper, so its color is red or white, and the real mobile phone battery should be this pure gold $, red. Or whitish may be fake.
I have read the above simple and practical little knowledge. I believe that you have already got a certain understanding of the mobile phone battery. I hope to bring benefits to you and the people around you, so as not to be deceived, and you can buy genuine goods. cell phone battery.
DMC dust collector products are widely used in casting industry, ceramic industry, glass industry and refractory materials, cement building materials, grinding wheel manufacturing, chemical products machinery processing and other industries of dust removal, the product of a large proportion of metal chips, casting sand, such as lathes, grinding machines, polishing machines, grinders, milling machines and so on, And medium proportion of formicwood powder, plastic powder, dust, ceramic powder, gypsum powder, asbestos powder, carbon powder, pigment and so on, as well as the proportion of light non-fibrous dust have good dust removal effect, the dust removal efficiency of the unit is more than 99.5 percent.
DMC bag dust collector is a small size, high dust removal efficiency of local dust removal equipment, suitable for a variety of independent dust production points, flexible and convenient, local dust collection, local treatment, can effectively ensure the cleanliness of the air.
1. Dust removal equipment adopts high efficiency, low consumption injection device, to achieve low pressure, short pulse injection technology;
2. The filter bag is firmly fixed and easy to disassemble. The filter bag is embedded in the flower board with an elastic ring sewn at the mouth of the bag to completely eliminate dust leakage. It is convenient to disassemble and install the filter bag, and the contact between people and the filter bag is short without pollution;
3. Long filter bag. The filter bag can grow to 6 meters or longer, which greatly breaks through the bag length limit of the pulse dust collector, and the dust removal effect is good;
4. Small footprint. Single row or double row combination design can be carried out according to the treatment gas volume and site location;
5. The dust collector itself has no transmission parts, and only needs inspection during operation, basically no maintenance.
