After the ordinary consumers buy the cottage phone, during the use, they will find that the battery has a strong endurance without the label. So, how big is the mobile phone battery in the cottage? At present, the general production technology and level of the cottage mobile phone, its battery life is basically the same as the ordinary battery of the brand machine. More intuitively speaking, the frequency and duration of using a mobile phone by an ordinary consumer can generally stand for about 3 days.
Mobile phone batteries frequently explode, most of them are cottage batteries. How to identify the cottage battery has become a concern of people.
First, look at the capacity
The general cadmium nickel battery is 500mAh or 600mAh, and the hydrogen nickel battery is only 800-900mAh; while the lithium ion mobile phone battery is generally between 1300-1400mAh, so the lithium ion battery is fully charged and the time is about hydrogen nickel battery. 1.5 times, it is about 3.0 times that of cadmium nickel battery. If you find that the working hours of the lithium-ion mobile phone battery block you purchased are not advertised or as long as specified in the manual, it may be counterfeit.
Second, look at the surface of plastic materials
Authentic battery wear surface is uniform, using PC material, no brittle phenomenon; counterfeit battery is not wear-resistant or too rough, using recycled material, easy to crack. 3. Look at the appearance. All genuine mobile phone batteries should be neat and tidy, with no extra burrs, a certain roughness on the outer surface and a comfortable hand; the inner surface is smooth, and fine vertical scratches are seen under the light. The battery electrode and the mobile phone battery have the same width, and the corresponding positions under the battery electrode are marked with [+], [-], and the battery charging electrode is the same as the outer casing material, but not integrated.
Third, look at the signs
For the original battery, its battery surface color texture is clear, uniform, clean, no obvious scratches and damage; battery label should be printed with the battery model, type, rated capacity, standard voltage, positive and negative signs, manufacturer name. When the mobile phone is on, it should be smooth and non-blocking, suitable for tightness, good fit with the hand, reliable lock; the hardware has no obvious scratches and black and green. If the cell phone battery we purchased does not match the above phenomenon, it can be preliminarily determined to be a fake.
Fourth, look at the color
At present, many mobile phone manufacturers have also made efforts to improve the level of craftsmanship to strengthen the difficulty of fraud in mobile phones and their Accessories, thereby further curbing the phenomenon of counterfeit goods. Generally, regular mobile phone products and their accessories must be consistent in appearance. Therefore, if we put the purchased mobile phone battery, we should carefully compare the color of the fuselage and the battery bottom case. If the color is dark and the same, it is the original battery. Otherwise, the battery itself is dull and dull, and it may be a fake battery.
Fifth, look at the protection device
Observe the abnormality of charging. Generally, the internal mobile phone battery should have an overcurrent protector. When the external short circuit causes the current to be too large, the circuit will be automatically cut off to avoid burning or damage the mobile phone. The lithium ion battery has an overcurrent protection circuit when using non-standard electrical appliances. When the AC current is too large, the power will be automatically cut off, resulting in no charge. When the battery is normal, it can automatically return to the conduction state. If, during the charging process, we find that the battery is seriously hot, or smoke or even explode, the battery is definitely fake.
Six, see security
Look carefully at the security signs. For example, the word NOKIA under the sticker is hidden. Clear and flawless is the original product; dim color is counterfeit. If you look closely, you may also find the name of the manufacturer. For example, for Motorola batteries, its anti-counterfeiting trademark is diamond-shaped, and it can be flashed with stereoscopic effect from any angle, while Motorola, Original and printing are clear, it is genuine. On the contrary, once the color is dim, the stereoscopic effect is insufficient, and the words are vague, it may be a fake.
Seven, measuring voltage
Measure the charging voltage of the battery block. If a lithium-ion mobile phone battery block is used to spoof a lithium-ion mobile phone battery block, it must be composed of five single cells. The charging voltage of a single battery generally does not exceed 1.55V, and the total voltage of the battery block does not exceed 7.75V. When the total charging voltage of the battery block is lower than 8.0V, it may be a nickel-cadmium or a nickel-hydrogen battery.
Spun Pile Cage Welding Machine
A spun pile cage welding machine is a specialized equipment used for welding steel cages for spun piles. Spun piles are concrete piles that are manufactured by centrifugal spinning. The machine is designed to produce high-quality welded cages that are used to reinforce the concrete piles.
