| Verification of Real and Fake Batteries for Mobile Phone |
一、Length of Standby Duration
As an important measurement of battery quality, the length of battery’s standby duration is determined by the balanced performance of all rechargeable cells forming the battery. The standby duration of a real battery should be largely the same with what stated in user manual, while that of a fake battery is only about half long. Some shoddy quality battery is assembled with a second-handed battery core as the core and a new package. In case the seller cannot guarantee the standby duration is the same with that of the user manual, do not buy this kind of battery. Some sellers make vacant promises although they in fact have no idea of the actual capacity of battery. This kind of battery is usually made with poor quality battery core. If you find the standby duration of the battery you buy is short, demand your money back or have a good battery.
二、
Battery Capacity

The capacity of a mobile phone battery usually consists of two types, 1000 mA/hour or 1000mAh. The capacity logo of some fake battery either does not exist or is not clear. You can also go to a mobile phone repair shop to measure battery current and verify it is real or fake. All of us use lithium battery today, while lithium battery is composed of a string of almost No. 5 and No.7 battery cells and equipped with switch device and protection circuit. So it has certain weight. If the lithium battery you buy is too light, it indicates the battery core capacity is insufficient, and the battery may be fake. The weight of a 900mAh lithium battery core is typically 35g. If the weight of the battery core, other device and the shell of a battery is less than 35g, this battery is probably fake.
三、Safety
Mobile phone battery is inflammable and is apt to explode. If there is no protection circuit inside, the battery tends to change in shape, leak liquid or even explode. However, many shoddy quality batteries save this circuit protection board so as to lure consumers with low price and make more profits. These unsafe batteries in the market are not a few and it is hard to identify them from appearance. You’d better buy them in formal shops.
There are primarily three types of batteries in the market today: lithium ion battery, Ni-MH battery and Ni battery. Thanks to its biggest capacity, long standby duration and lightweight, lithium ion battery is the dominant form of battery. Henceforward, all statements above are primarily based on the lithium battery.
- Appearance Identification
The common problems of fake and shoddy batteries include: poor quality of battery chip, the core part inside the battery, insufficient charging capacity, short discharge duration, poor damage-proof performance, non-compliance of marked and actual battery capacity, etc. All these lead to short standby and talk durations of the phone, fake charging saturation and quick discharge exhaustion of battery, or even automatic powering off of the phone.
Currently the market is swarm with fake and shoddy phone batteries, which harm the interests of many consumers. Real mobile phone battery usually has following appearance features: The battery label employs secondary printing technology, if you look at it from an slant angle under certain light, the color of the bar code is apparently darker than the color of other parts, and you will feel the bar code part is a little higher than other parts when you feel it with fingers. Many original packaged batteries have this feature. If you scratch the white part of the label surface of real battery with a metal object, a trace as if scratched by a pencil will be left. The battery shell is made of special material, very firm and can hardly be damaged. The battery shell is hard to open in usual case, the battery appearance is neat, there is no redundant burr, the appearance surface is a bit coarse, the finger feeling is comfortable, the internal surface is smooth, and thin longitudinal scratch trace can be seen under lamp light.

The battery electrode is as wide as mobile phone battery, the relevant position below the battery electrode is marked with “+” and “-” signs, the isolating material between the charging electrode plates of the battery is the same with that of the shell, but not integrated. The finger feeling should be comfortable and easy when the battery is installed in the mobile phone. The click-to-install part of the battery lock should be proper and firm. The characters of the battery label should be clear, and a battery number corresponding to the battery type is shown. The producer sign in the battery should have a clear contour, and the anti-fake sign in the battery has good luminosity and a cubic sense.
- Feel Its Weight
Generally, the weight of lithium ion battery is light, and each battery is roughly over 100 grams. Considering this apparent feature, fake products cannot be made easily, and we can verify the battery is fake or not by feeling the weight of mobile phone battery. After all, the batteries of other categories vary significantly from lithium ion battery in weight. Weigh the weight in a simple way, if the weight of a battery is too much from 100 grams, you can probably conclude this battery is fake.
The advantage of this kind of method is that the verification is plain to see and the operation is simple too. The disadvantage is that the verification scope is limited, it works only to the verification of lithium ion battery, and it is not so convenient to implement.
- Observe Its Appearance and Color
You can observe the appearance and color of mobile phone battery to see if they are consistent of the appearance and color of mobile phone. To gain a strong foothold in this messy market and protect their own interests well, many mobile phone producers strive to improve their technologies and the manufacturing process level of mobile phone battery constantly, expecting to suppress fake products with good quality and ensure the sales of their batteries. Generally, the appearance and color of real mobile phone are fully identical to the appearance and color of mobile phone battery. Therefore, we can install the just selected battery to the phone to see if their colors are the same. In case their appearance, luster and color are apparently different, the battery is probably fake.
- Identification Method of Quality of Material
Some categories of mobile phone batteries can be verified to be fake or not by inspecting whether the quality of material of the joint position is hard or not. Press the round arched shaped joint position of the mobile phone battery, and fell how hard the joint position is with fingers. Generally, the quality of material of the joint position of real mobile phone battery is relatively much softer and has some elasticity. Particularly, a smooth, block-free and comfortable feeling should be felt when the battery is inserted in the mobile phone, and the tightness is proper, works harmoniously with the mobile phone and the lock is firm. On the contrary, the quality of material of shoddy quality battery is much harder, and the battery is not easy to slide into the mobile phone battery groove when it is installed.

The advantage of this method lies in easy operation. The disadvantage is that the verification accuracy is not so high and the verification scope is limited.
- Package Identification Method
Every mobile phone battery of good quality looks neat and clean in appearance, whose luster and texture are very clear, and there is no scratch and damage in the surface of shell. The label pasted on the battery shell should include type, model, capacity, anode and cathode signs, standard voltage, battery maker and other parameters. Besides, the metal contact of the battery should be free of scratch and green or black mold. In case the mobile phone battery you select is different from what described above with real mobile phone battery, you are basically sure you have bought a fake battery.
- Charging Observation Method
Generally, mobile phone battery with good performance has overcurrent protection device inside. Once a short circuit occurs outside of the mobile phone and a high shock current occurs, the said overcurrent protection device disconnects the charging loop automatically so as to avoid the mobile phone battery to be damaged or burned because of high current shock. While in shoddy quality battery, such overcurrent protection device is unlikely to exist. Such battery may become very hot in the shell after long time of charging and may produce smoke in worst case. If a battery becomes very hot after a short time of charging, it is probably an inferior quality product. The greatest advantage of this kind of verification method is that it can test the mobile phone battery to be real or fake pretty accurately and works to all kinds of batteries.
These methods mentioned above may be stupid but are very practical. As a whole, they can help most people to select batteries. I hope they can help you to buy inexpensive and quality batteries.
