Package distinguish France

The superior quality of each piece of mobile phone batteries, from the outside looks are neat and clean, color texture is very clear, the surface casing has no scratches and damage the office; and posted on the label the battery case, should include the Toshiba Tecra S2 battery type, model, capacity , positive and negative signs, standard voltage, battery manufacturers names and other parameters. In addition, the battery touch metal on the chip, it should be no scratches, should not become moldy with green or black phenomenon. 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 basically identify the current purchase of the battery is fake.

Charge observation

In general, the superior performance of the cell phone battery, an internal over-current protection device, once the external short-circuit the phone, give rise to significant impact on current, the overcurrent protection device can automatically cut off the charging circuit in order to avoid cell phone batteries due to high current the impact of the phenomenon of the event of damage or burning. The bad battery is likely that there is no over-current protection devices; so lengthy battery charging, the battery shell may appear the phenomenon of boiling, the worst case, smoking behavior may occur. If the battery charge did not take long, hot phenomenon appeared, then the battery 10 with ** are defective. This identification method, the biggest advantage is the ability to more accurately test the genuine and fake mobile phone batteries come out, but also a variety of Toshiba Portege M200 battery are valid.

These methods are and the various vendors and a few friends in chat when the shrimp-class summed up. In general, the machine is suitable for the vast majority of Friends of the selection battery. Some of these methods though stupid, but very useful indeed. Hoping to buy for everyone for the love machine when the Toshiba Satellite A60 battery can buy as cheap and high quality products.

Color

Here’s “See the color,” in fact refers to the carefully observed the appearance of the color mobile phone battery, whether appearance of the color line and cell phone. At present, many mobile phone manufacturers, in order to gain a firm foothold in the market quite a mixed bag, protecting their own interests, often through continuous technological innovation, to strive to improve the Toshiba Satellite A100 battery technological level mobile phone batteries, with a view through the quality of suppression of high-quality counterfeit batteries to ensure that battery sales. Under normal circumstances, the appearance of genuine mobile phone batteries appearance of colors and color is identical. Therefore, we can just choose to install the battery cell phone to see if the color is the same between them, if between them the appearance of color, there is a clear difference in color, the battery most likely is fake and shoddy products.

Texture identification method

Some types of mobile phone Toshiba Satellite Pro 6100 battery, we can point texture according to whether or not the hard way to identify genuine and fake batteries. Force pressing the dome-shaped cell phone battery point, and directly with your fingers and feel the soft and hard levels of the conjugate point. Often, a combination of genuine mobile phone batteries are relatively soft texture of a number of points, but also show some flexibility, especially in the battery when inserted into the phone, there is a smooth non-blocking, insert the comfortable feeling, and elastic fit, and cell phone with a very harmonious, stable and reliable locking; on the contrary, poor battery relatively hard texture a little more, and the Toshiba Satellite A65 battery installed, not very easy to “slip” into the cell phone battery slot.

This method has the advantage that operation is very simple, the same is also suitable for “rookie” user. The disadvantage is that identification accuracy is not high, and the identification of a limited range!

Appearance distinguish

Existence of fake battery are a common problem: the battery inside the core components??? Battery chips of poor quality, insufficient charge and discharge time is short, anti-sabotage poor performance, the marked discrepancies with the actual battery capacity.

Currently on the market flooded with counterfeit mobile phone battery, so that the interests of many Toshiba NB200 battery consumers suffer. Genuine mobile phone battery generally have the following exterior features: battery label use of the second printing technology, in a certain light, and from the slope of view, part of the color bar code significantly more than in other parts of the black, and Mo Shangqu hand feel a little more than other parts of the convex, many with original equipment battery have this characteristic. Genuine battery label at the surface of the white light with metal objects designated, have similar across traces of a pencil. Battery shell is made with special material, very strong, difficult to damage, under normal circumstances is not easy to open the battery case, battery and tidy appearance, there is no extra burr, a certain degree of roughness of the outer Toshiba Satellite A105 battery surface and feel comfortable, feel smooth inner surface, lighting be able to see finer vertical scratches.

Cell phone battery film electrode and the width of the same corresponding position in the bottom of the battery electrodes marked “+”"-” mark, battery charging electrodes separation between the materials and shell materials, the same as, but not one. battery into mobile phones should feel comfortable, comfortable. Battery lock push part of the card spaces appropriate, firmly. The battery label writing clear, there are corresponding with the battery type of battery parts number. Battery manufacturers should outline a clear, and the anti-counterfeiting marks the Toshiba Satellite M115 battery brightness is good, there are three-dimensional look.

Weigh 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 of and can not fake Toshiba Satellite A135 battery, we can use the method of measuring the weight of mobile phone battery to identify whether the battery only ” sell dog meat “of the type, after all other types of battery, and lithium-ion battery in terms of weight difference between the relatively large, a simple one, said that the weight of too much or if the battery are overweight too far away from the 100 grams of the standard, then, we can roughly be inferred The battery are fake and shoddy products.

Has the advantage of this method to identify them more intuitive Toshiba Satellite M70 battery, the operation is simple. The disadvantage is that identification is limited in scope to the identification of lithium-ion battery effective, and inconvenient to implement, who will carry it around with a steelyard in?

True and false identification of mobile phone battery

First, the length of standby time

The length of the battery standby time is an important indicator to measure strengths and weaknesses of the battery. Battery life is the length of time constitutes a single battery charge battery balanced decision. Battery standby time and the instructions are really on the Toshiba Qosmio F50 battery logo to be basically the same. The false identification of only half the time. Some low-quality battery is used as the secondary battery cell core, coupled with new packaging assembly made of. If the seller can not guarantee standby time in line with the instructions, you can not buy the batteries. Some sellers promises, in fact, he did not know the battery’s actual capacity, but only casually spoken. This battery is generally poor quality of the battery cell manufacturing. If found to stand a short time after purchase should be returned immediately asked.

Second, the battery capacity

Mobile phone battery capacity generally of 1000 mA / hour or 1000mah two kinds. Some did not leave the battery capacity of identification, there is also illegible logo. The battery can also be obtained to measure the current mobile phone repair shop in order to distinguish the authenticity. Now we are all used in lithium batteries, but lithium batteries by several sections 5 and 7, similar to the size of the battery string together, coupled with switching devices and protection circuits formed. Therefore, it has a certain weight. If you buy a lithium battery too light, indicating insufficient capacity battery cell, the battery may be a problem. General 900mah lithium battery cell weighs 35g, if a battery cell core plus other equipment and the battery shell weighs less than 35g, then this piece of the battery may be false Toshiba Satellite M45 battery .

Third, security

Mobile phone battery is inflammable and explosive articles, and if the battery does not protect the internal circuitry, it easy to deformation, leakage, or even an explosion. However, many low-quality batteries for a low price to attract consumers, removed the piece of circuit protection board, in order to earn greater profits. The battery on the market this insecurity is also a lot of people from Toshiba Satellite A100 battery appearance difficult to identify. The best time of purchase to the store to buy the regular telecom.

Mobile phone batteries on the market today are mainly three types: lithium-ion batteries, nickel hydrogen batteries and nickel Toshiba Satellite A50 battery. The largest capacity for lithium-ion battery, standby time, long, light weight, is the mainstream varieties of cell phone batteries. Therefore, as described above are mainly lithium batteries.
