At present, the mobile phone is an indispensable tool for people, and it will be updated quickly.The battery life of a cell phone is limited, so sometimes the cell phone is still good, but the battery has been very useless, this time, buy a new cell phone battery is a must.As a mobile phone user, in the face of the market flooded with fake and shoddy battery how to choose?Here, I'll teach you a few tips that I hope will help you improve your understanding of cell phone batteries.
1. Compare the battery capacity.General cadmium nickel battery for 500mAh or 600mAh, nickel hydrogen battery is also only 800-900mah;And the capacity of lithium ion mobile phone battery is generally between 1300-1400mah, so the energy storage lithium battery manufacturer after full power use time is about 1.5 times of the nickel hydrogen battery, is about 3.0 times of the nickel cadmium battery.If you find that the lithium ion cell phone battery you purchased does not work as long as advertised or as stated in the manual, it may be counterfeit.
2. Look at plastic surfaces and plastic materials.The genuine battery has uniform anti-wear surface and is made of PC material without cracking.The fake battery has no anti-wear surface or is too rough, and is made of recycled material, which is easy to crack.
3. All genuine cell phone batteries should be neat in appearance without excessive burrs, and have certain roughness on the outside surface and feel comfortable;The inner surface feels smooth, and fine longitudinal scratches can be seen under the light.The battery electrode is the same width as the cell phone battery, and the corresponding position below the battery electrode is marked with [+] and [-] marks. The isolation material of the battery charging electrode is the same as the shell material, but it is not integrated.
4. For the original battery, its battery surface color and texture is clear, uniform, clean, no obvious scratches and damage;Battery logo shall be printed with battery model, type, rated capacity, standard voltage, positive and negative marks, manufacturer name.Feel smooth without blocking, suitable tightness, good coordination with the hand, reliable lock;No obvious scratch and black, green metal pieces.If the mobile phone battery we bought is not consistent with the above phenomenon, we can preliminarily conclude that it is a fake.
5.At present, many mobile phone manufacturers also from their own point of view, through efforts to improve the technical level, to increase the difficulty of counterfeiting mobile phones and accessories, so as to further curb the flood of fake goods.General normal mobile phone products and accessories must be consistent in appearance.So if we buy a cell phone battery to install, should carefully check the body and battery bottom shell?Color, if colour and lustre light is dark consistent, it is original outfit battery.Otherwise, the battery itself is dull and dull, it may be a fake battery.
6. Observe abnormal charging conditions.In general, there should be an overcurrent protector inside the battery of a genuine mobile phone. In the case of external short circuit and other guiding calls, the circuit will be automatically cut off to avoid burning or damaging the mobile phone.Lithium ion battery has another overcurrent protection line, when the use of non-standard electrical appliances, too much alternating current will automatically cut off the power supply, resulting in not charging, in the normal condition of the battery, can be automatically restored to the conduction state.If, during the charging process, we find that the battery heats up or smokes or even explodes, the battery must be a fake.
7, carefully look at the security signs.NOKIA, for example, is obliquely printed under the sticker.Clear and flawless is the original factory products;Dim and pale is a counterfeit product.
If you look closely, you may find the name of the maker.For example, Motorola battery, its security trademark is a diamond, and no matter from any point of view, can flicker with a three-dimensional effect, and Motorola, Original and printed and clear, it is a genuine.On the contrary, if the color is dim, the sense of third dimension is insufficient, and the words are blurred, it may be a fake.
8. Measure the charging voltage of battery block.If a nickel cadmium and nickel hydrogen battery block is used as a lithium ion cell phone battery block, it must be composed of five single batteries. The charging voltage of a single battery is generally not more than 1.55V, and the total voltage of the battery block is not more than 7.75V.When the total charging voltage of the battery block is lower than 8.0V, it may be nickel cadmium and nickel hydrogen batteries.
9. Use special tools.In the face of the market more and more kinds of mobile phone batteries, and counterfeit technology is more and more clever, some big companies are also constantly improve the anti-counterfeiting technology, the new nokia mobile phone batteries, for example, it has carried on the special treatment on logo, need to identify with a particular type of prism, and this kind of prism only nokia has.Therefore, with the improvement of anti-counterfeiting technology, it is difficult for us to identify the real from the appearance.
