First, the length of standby time
The length of battery standby time is an important indicator to measure the merits of the battery. Battery standby time is the length of the monomer composition of the battery cell balance charging decisions. Really Battery standby time and instructions on the logo should be consistent. The false identity only half the time. Some poor battery cell battery is used as the kernel, with new packaging assembled. If the seller does not guarantee the same standby time with the manual, you can not buy this battery. Some sellers pledged, in fact, he does not know the actual battery capacity, but just oral only. This battery is generally of poor quality battery cell manufacturing. If the purchase and found standby time is short, requirements should be returned immediately.
Second, the battery capacity
Mobile phone battery capacity is generally 1000 mA / h or 1000mah two. Some did not leave the battery capacity of identification, a logo is illegible. Can get the battery to measure the current mobile phone repair shop in order to distinguish the authenticity. Now we are using lithium batteries, and lithium is similar to sections 5 and on the 7th string together the size of the acer aspire 5920g battery, coupled with switchgear and protection circuit of. So it has some weight. If you buy a lithium battery too light, the battery cell capacity is insufficient, the battery may be a problem. General 900mah lithium battery core weight of 35g, if a battery cell battery plus other equipment and the battery shell weighs less than 35g, that this battery may be false.
Third, the security
Mobile phone battery is inflammable and explosive materials, if there is no internal battery protection circuit, it can easily deformation, leakage, or explosion. However, many low-quality battery at low prices to attract consumers in order to remove a piece of circuit protection board, in order to earn greater profits. Battery on the market has a lot of this insecurity, we are difficult to identify from the appearance. To purchase the best stores to buy the regular telecommunications.
Mobile phone batteries on the market today there are three types: lithium-ion batteries, nickel metal hydride batteries and nickel acer aspire 3000 battery. Maximum capacity for lithium-ion battery, long standby time, light weight, mobile phone battery is the main varieties. Therefore, the above are lithium based.
Look to identify
Counterfeit batteries common problems are: the core component of the battery??? Battery chips of poor quality, insufficient charge, discharge time is short, anti-sabotage poor performance, the standard battery capacity and the actual discrepancies.
The market is flooded with counterfeit mobile phone batteries, damage the interests of many consumers. Genuine mobile phone batteries generally have the following exterior features: the use of the secondary battery label printing technology, in a certain light, from the slope of view, part of the color bar code significantly darker than the rest, and the hand feels, I feel a little more than other parts of the convex, many original batteries have this feature. Genuine battery label at the surface of white light with a metal program, similar to a pencil across the scene. Battery case made of special material, very strong, difficult to damage, under normal circumstances is not easy to open the apple a1189 battery case, battery neat appearance, no extra burr, the outer surface has some roughness and feel comfortable, feel smooth inner surface, light can see fine vertical scratches.
Cells electrode and the width of the same cell phone, battery electrodes below the corresponding position marked "+""-" mark, battery electrodes isolation between the same materials and shell materials, but not one. Battery into the phone should feel comfortable and ease. Press the battery lock part of card-bit properly, firmly. Battery label writing clear, and corresponds to the type of battery the battery part number. Battery manufacturers should outline clear, good brightness and security signs, three-dimensional look.
Weigh weight
Typically, relatively light weight of lithium-ion batteries, each battery is about more than 100 grams; taking into account the obvious features and can not fake, we can use methods of measuring the weight of mobile phone batteries, to identify whether the apple a1175 battery is only " sell dog meat, "the type, after all other types of batteries, and lithium-ion batteries on the relatively large difference in weight, simply known a known weight of too much or if the battery is overweight too far away from the 100 g standard, then, we can roughly infer The battery is fake and shoddy products.
Advantage of this approach is to identify them more intuitive, very simple to operate. The disadvantage is the limited scope of identification, identification of lithium-ion battery only effective, but not very convenient to implement, who would carry it around with a steelyard?
How the wind blows
Here, "the wind blows", in fact, refers to the careful observation of the color appearance of mobile phone batteries, cell phone whether the appearance of the same color. Currently, many mobile phone manufacturers, in order to gain a firm foothold in the market quite a mixed bag, protect their own interests, often through continuous technological innovation, to strive to improve the technological level of mobile phone battery, with a view to suppression by high-quality counterfeit dell inspiron e1705 battery to ensure quality battery sales. Under normal circumstances, the appearance of genuine mobile phone batteries with the appearance of color the color is exactly the same. Therefore, we can just choose to install to the phone's battery, to see whether the same color between them, between them if the appearance of color, the color is a clear difference, the battery is most likely fake and shoddy products.
Texture identification method
Some types of mobile phone batteries, we can point hard texture or in accordance with the methods to identify genuine and fake hp elitebook 6930p battery. Firmly press the mobile phone battery with arched point, and directly with your fingers feel the hardness of the binding sites. Typically, a combination of genuine mobile phone batteries is relatively soft texture of some points, but also show some flexibility, especially in the battery when inserted into the phone, there is a smooth non-blocking, insert comfortable feeling, and elastic fit, and phone with a very harmonious, stable and reliable lock; contrast, poor battery some of the texture is more hard, and when the battery is installed, not quite easy to "slip" into the cell phone battery slot.
Advantages of this method is very simple operation, also for "rookie" user. Disadvantage is that identification accuracy is not high, and the identification of a limited range!
Packaging method to identify
Superior quality of each piece of mobile phone batteries, from the outside looks are neat and clean, color, texture is very clear, no scratches the surface casing and damage of the Department; and posted on the hp probook 4710s battery case label should include the type, model, capacity , positive and negative signs, standard voltage, battery manufacturers name and other parameters. In addition, the metal contacts on the battery, it should be no scratches, and do not have green or black moldy phenomenon. If you pick the phone's battery, and the genuine mobile phone batteries described above, the appearance of the phenomenon is not the same, you can buy basically confirmed the current battery is fake.
1 more battery capacity size. General or nickel-cadmium battery is 500mAh 600mAh, Ni-MH batteries, but 800-900mAh; and the capacity of lithium-ion cell phone batteries are generally between the 1300-1400mAh, lithium-ion battery is fully charged so use the time after about nickel-hydrogen battery 1.5 times that of nickel-cadmium batteries of 3.0 times. If you find that you have purchased a block of lithium-ion cell phone battery working time and not propaganda or instructions required length, it may be fake.
(2) see the plastic surface and the plastic material. Genuine battery wear uniform surface, using the PC material, no embrittlement phenomenon; counterfeit compaq presario cq50 battery not wear surface or too rough, using recycled material, easy to rattle.
3 All genuine mobile phone batteries, appearance should be neat, no extra burr, the outer surface has some roughness and feel comfortable; the inner surface of the touch is smooth, light can see fine vertical scratches. Cells electrode and the width of the same cell phone, battery electrodes below the corresponding position marked [+],[-] mark, battery electrode materials, isolation materials and the same shell, but not one.
4 for the original battery, its battery surface color texture clear, uniform, clean, no scratches and damage; battery symbol should be printed on the battery model, type, rated capacity, standard voltage, positive and negative signs, factory name. Should feel smooth on the phone non-blocking, elastic fit, and with good hands, lock and reliable; metal film no scratches and black, green phenomenon. If we buy mobile phone batteries and do not meet the above phenomena can be initially determined to be fake.
5 Currently, many mobile phone manufacturers from its own perspective, through efforts to improve the technological level, to increase the difficulty of false mobile phone and its accessories to further curb the proliferation of fake parallel phenomenon. General formal requirements of mobile phone products and accessories must be consistent in appearance. So we bought the phone if the battery is installed, you should carefully control what the body and the battery bottom shell color, if the color and brightness consistency, is the original battery. Otherwise, the battery itself is dull dull, there is a counterfeit battery.
6 charge of the anomalies observed. General, genuine mobile phone batteries should be within the over-current protection device, as a result of the external short-circuit current is too large, the automatic cut off the circuit, so as not to burn or damage the device; lithium-ion batteries also have over-current protection circuit, when using non-standard electrical , AC electric current is too large will automatically cut off power supply, resulting in charge does not enter normal conditions the battery can be automatically restored to the conduction state. If, in charge of the process we found that the battery of serious heat or smoke, or explosion, the battery is definitely false.
7, a close look at security signs. Such as stickers hidden under the ramp NOKIA printed words, is one of the tips. Clarity is the original product; eclipse is a counterfeit product. If you look closely, you may find the manufacturer's name. For example, Motorola batteries, it's anti-counterfeit trademark is diamond-shaped, and from whatever point of view, can be flashing three-dimensional effect, while Motorola, Original and printing and clear, then it is genuine. On the contrary, once the color of dark, three-dimensional feeling inadequate, vague words, there may be fakes.
8 measure the charging voltage of the battery block. If Ni-Cd, Ni-MH battery block counterfeit lithium-ion cell phone battery block, it must be composed of five single battery, single battery charge voltage not more than 1.55V, the battery voltage does not exceed the total block of 7.75V. When charging the battery block is lower than 8.0V when the total voltage may be nickel-cadmium, nickel hydrogen batteries.
9 with special tools. The face of mobile phone batteries on the market more and more types, but the technology is becoming more sophisticated fake, some large companies are constantly improving anti-counterfeiting technology, such as the new Nokia mobile phone battery, it is marked on a special processing, the need to use a special prism to identify, and this prism only Nokia have. Thus, with improved anti-counterfeiting technology, we are also very difficult to look up from the true and false identification.
10 using a dedicated detector. The quality of mobile phone batteries, one is hard to determine from the appearance on the merits. To this end, the market launch of a mobile phone battery detector, the detector can be battery voltage 2.4V-6.0V for between less than capacity 1999mAH lithium, nickel and other battery capacity, quality testing discrimination, and can activate, charge and discharge functions. Entire process according to the battery characteristics by the microprocessor control, digital display the measured voltage, current, capacity and other technical parameters.
11 lithium-ion cell phone batteries outside the general standard in English 7.2Vlithiumionbattery (lithium-ion battery) or 7.2Vlithiumsecondarybattery (lithium secondary battery), 7.2Vlithiumionrechargeablebattery (Li-ion rechargeable battery). So be sure to buy cell phone batteries battery block to see the appearance of the sign, because did not see the battery to prevent the type of nickel-cadmium, nickel hydrogen batteries mistaken for lithium-ion cell phone batteries.
12 Tell everyone in the battery when the often overlooked a small detail that the battery contacts. True for various brand-name cell phone batteries, their contacts mostly been annealed, it should be matte, not shiny, so it can be initially determined based on what cell phone battery for authenticity. Also closer look at the color contacts, fake cell phone battery contacts are often made of copper, so it's the color red or white, but really this is the cell phone battery should be pure golden yellow, red or white on are likely to be false.
The length of battery standby time is an important indicator to measure the merits of the battery. Battery standby time is the length of the monomer composition of the battery cell balance charging decisions. Really Battery standby time and instructions on the logo should be consistent. The false identity only half the time. Some poor battery cell battery is used as the kernel, with new packaging assembled. If the seller does not guarantee the same standby time with the manual, you can not buy this battery. Some sellers pledged, in fact, he does not know the actual battery capacity, but just oral only.
