Identification method of lithium battery
"Lithium battery" is a kind of battery with lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution. Below, I will share the identification method of lithium battery for you, hoping to help you!
Compare the battery capacity
The average nickel-cadmium battery is 5mAh or 6mAh, and the nickel-hydrogen battery is only 8-9mAh; The capacity of lithium-ion mobile phone batteries is generally between 13-14mAh, so the use time of lithium batteries after full charge is about 1.5 times that of nickel-hydrogen batteries and about 3. times that of nickel-cadmium batteries. If it is found that the working time of the lithium-ion mobile phone battery block you bought is not as long as advertised or specified in the manual, it may be counterfeit.
Look at the plastic surface and plastic material
The wear-resistant surface of the genuine battery is uniform, made of PC material, and there is no brittle crack; Counterfeit batteries have no wear-resistant surface or are too rough, and are made of recycled materials, which are easy to crack.
measuring the charging voltage of the battery block
If the battery block of lithium-ion mobile phone is made of Ni-Cd or Ni-MH battery, it must be composed of five single batteries. Generally, the charging voltage of a single battery does not exceed 1.55V, and the total voltage of the battery block does not exceed 7.75V V. When the total charging voltage of the battery block is less than 8.V, it may be Ni-Cd or Ni-MH battery.
For the original battery, its surface color and texture are clear, uniform and clean, without obvious scratches and damage; The battery logo should be printed with the battery model, type, rated capacity, standard voltage, positive and negative signs, and the name of the manufacturer
. The feel should be smooth and unobstructed, the tightness should be appropriate, and the lock should be reliable. There is no obvious scratch, blackening and greening on the metal piece. If the mobile phone battery we bought does not conform to the above phenomenon, we can preliminarily conclude that it is a fake.
Many mobile phone manufacturers have also made efforts to improve their technological level from their own perspective, so as to improve the difficulty of counterfeiting mobile phones and their accessories, thus further curbing the phenomenon of counterfeit parallel imports.
general regular mobile phone products and their accessories require consistency in appearance. Therefore, when we install the bought mobile phone battery, we should carefully compare the fuselage with the battery bottom case? Color, if the color is the same, it is the original battery. Otherwise, the battery itself is dull, and it may be a fake battery.
Observe the abnormal charging situation
Generally, there should be an overcurrent protector inside the genuine mobile phone battery, which will automatically cut off the circuit in case of excessive current caused by external short circuit, so as to avoid burning or damaging the mobile phone; Lithium-ion battery also has an overcurrent protection circuit. When nonstandard electrical appliances are used, the power supply will be automatically cut off when the alternating current is too large, resulting in charging failure. Under normal conditions, the battery can be automatically restored to the on state. If, in the process of charging, we find that the battery is seriously heated, smoked or even exploded, it means that the battery must be fake.
If you look closely, you may find the name of the manufacturer.
For example, for Motorola battery, its' anti-counterfeiting trademark is diamond-shaped, and it can flash with three-dimensional effect from any angle, but if Motorola, Original and printing are clear, it is genuine. On the contrary, once the color is dim, the three-dimensional sense is insufficient, and the words are vague, it may be a fake.
With the help of special tools
There are more and more kinds of mobile phone batteries in the market, and the counterfeit technology is becoming more and more sophisticated. Some large companies are constantly improving the anti-counterfeiting technology, such as the new Nokia mobile phone battery, which has been specially treated on the logo and needs to be identified by a special prism, which is only available in Nokia. Therefore, with the improvement of anti-counterfeiting technology, it is difficult for us to identify the authenticity from the appearance.
