Authentication of mobile phone batteries guidelines

Authentication of mobile phone batteries guidelines

First, the duration of standby time


The battery life saver is an important indicator to measure the strengths and weaknesses of the battery. Battery life is the length of time constitutes a single battery for camcorder battery charge battery balanced decision. Waiting time and the instructions are actually on the logo to be basically the same. The false identification of only half the time. Some low-quality battery is used as the core of secondary battery cells, made by compiling new packages. If the seller can not guarantee standby time in accordance with the instructions, you can not buy the batteries. Some vendors promise, in fact, he did not know the actual capacity of the battery, but only used in the language. This battery is generally of poor quality manufacturing of battery cells. If found to bear a little time after the purchase must be returned immediately asked.


Secondly, the battery capacity


Mobile phone battery capacity in general of 1000 mA / hour or two kinds 1000mAh. Some did not leave the battery capacity of identification, there is also the logo unreadable. The battery can also be obtained to measure the current repair shop mobile phones in order to distinguish the authenticity. Now we are all used in lithium batteries, lithium batteries, but several sections 5 and 7, similar to the size of the string of batteries at the same time, coupled with the circuit switching and protective devices formed. Therefore, it has a certain weight. If you buy a lithium too light, indicating the lack of cell capacity battery, the battery may be a problem. General 900mAh lithium cell battery weighs 35g, if a stack of basic plus additional equipment and the hull of the battery weighs less than 35g, then this part of the battery in May false.


3 Security


Mobile phone battery is flammable and explosive items, and if the battery does not protect the internal circuitry, it is easy to distortion, leakage, or even an explosion. However, many low-quality batteries at lower prices to attract consumers, removed the piece of shield circuit to macbook batteryearn more profits. The battery on the market this insecurity is also a lot of people from their appearance difficult to identify. The best time of purchase to the store to buy the traditional telecoms.
Of mobile phone batteries on the market today are basically three types: lithium-ion batteries, hydrogen fuel cells and nickel nickel. The largest capacity for lithium-ion battery, wait times, long, light weight, is that the ordinary varieties of cell phone batteries. Therefore, as described above are mainly lithium batteries.

Appearance distinguish


Existence of counterfeit batteries are a common problem: the battery in the basic components?? Bullets battery of poor quality, inadequate care and discharge time is short, anti-sabotage poor performance, the marked differences in the capacity of the battery current. All this has led to combined standby and talk time is short, the battery charge on the full, a statement on the end, and some have emerged the phenomenon of automatic shutdown.

Currently on the market flooded with counterfeit mobile phone batteries, so that the interests of consumers suffer much. Of mobile phone batteries usually contain authentic following Exterior features: use of the label stack of print technology on the other hand, in a certain light, and the slope of view, part of the barcode clear color than in other parts of the black and Mo Shangqu hand feel a little more than other parts of the convex, with many of the batteries original equipment have this feature. Label battery authentic on the surface of white light with metal objects designated, are similar across the traces of a pencil. Battery  apple iBook G4 12 inch battery， apple iBook G4 14 inch battery， apple MacBook 13 inch battery， apple MacBook Pro 15 inch batteryshell is made of special material, very strong, difficult to damage, under normal circumstances is not easy to open the battery case, battery and neat appearance, there is no extra burrs in some degree of roughness of the outer surface and feel comfortable, feel the smooth inner surface, lighting able to see more fine vertical stripes.

Cell Phone electrode film of the battery and the width of the same corresponding position in the bottom electrode of the battery marked "+""-" brand recharge the battery electrodes separation between the equipment and hull materials, and as, but not one. Batteries in mobile phones should feel at ease, comfortable. Push lock the battery in the premises of an appropriate card firmly. The battery label clear writing, there is correspondence with the type of battery battery parts number. Battery manufacturers should set out clearly, and the fight against counterfeit marks the brightness is good, there are three dimensional search.

Weigh the weight


Under normal circumstances, the weight of lightweight lithium-ion battery, each battery is about more than 100 grams, taking into account the obvious characteristics and can not fake, we can use the method for measuring the weight of the phone batteries mobile to determine if the battery only "sale of dog meat" of the type, after all other types of batteries and lithium-ion batteries in terms of weight difference between the relatively large number, a simple, says the weight of too much or if the batteries are overweight too far from the 100 grams of the standard, then we can usually deduct out of the battery are fake and poor quality products.
A benefit of this method to identify them more intuitive, the operation is simple. The disadvantage is that the identification is limited in scope to the identification of lithium-ion batteries effective and impractical to implement, which will take it with a load cell in?

How the wind blows


Here's how the wind blows, "in fact, to the carefully observed the appearance of mobile phone battery color, so the appearance of the color line and cell phone. At present, mobile phone manufacturers to lasting foothold in the market while a mixed bag, to protect their own interests, often through technological innovation continues to strive to improve the technological level of mobiletopbattery  phone batteries, with a view through quality the removal of high-quality counterfeit batteries to ensure that battery sales. In normal circumstances, the emergence of a genuine appearance of mobile phone batteries color and the color is identical. Therefore, we simply choose to install the cell phone battery to see if the color is the same between them, so between them the appearance of color, there is a clear difference in color, the battery most likely is false and poor quality products.

Texture identification method


Some types of batteries for mobile phones, we can bring the texture according to whether or not the hard to identify genuine and fake batteries. Force pressing the dome in the shape of cell phone battery, and directly with your fingers and feel the soft and hard point conjugate. Often, the texture of a combination of mobile phone batteries are really a relatively low number of points, but also show some flexibility, particularly when the battery is inserted into the phone, it is a non-smooth block, insert the feeling of comfort, and elastic layout, and a cell phone to lock with a very smooth and stable and reliable, however, the relatively poor battery drive, a little more texture, and battery installed, not very easy to "slip" into the slot cell phone battery.
This method has the advantage of this operation is very simple, the same is also suitable for "rookie" of the user. The disadvantage is that identification accuracy is not high, and the identification of a limited series!

Package distinguish France


The quality of each piece of batteries for mobile phones, exterior looks are neat and clean, the texture color is very clear, the surface casing has no scratches and damage to the Office, and posted labeled on the battery case should include the type, model, capacity, signs of positive and negative voltage standard, the names of manufacturers of batteries and other parameters. In addition, the metal contact of the battery on the chip, there should be no scratches, should not become the phenomenon moldy green or black. If you choose to cell phone batteries, with a genuine mobile phone batteries described above, the phenomenon does not look the same, then it can be determined basically buying power of the battery is wrong.

Load Observer


In general, the superior performance of the mobile phone battery, an internal on-device protection current once the external short-circuit the phone, give rise to significant impact on current, protective device against overcurrent can automatically cut off the charging circuit to avoid cell phone batteries due to high current impact of the phenomenon of the manifestation of injury battery808 or burns. The defective battery is likely that there are not too many guards present, so long battery charging, the shell of the battery in May revealed the phenomenon of boiling, the worst case, smoking behavior is May produce. If the battery does not last long, a phenomenon appeared hot, then the probability, the battery is defective. This method of identification, the biggest advantage is the ability to better test the batteries of mobile phones out true or false, but also a variety of cells are valid.
