How to distinguish the authenticity of lithium battery products?

How to distinguish the authenticity of lithium battery products?Compare the size of battery capacity.

Typical cadmium nickel batteries have a capacity of 500mAh or 600mAh, while hydrogen nickel batteries have a capacity of only 800-900mAh; The capacity of lithium-ion mobile phone batteries is generally between 1300-1400mAh, so the usage time of lithium-ion batteries after being fully charged is about 1.5 times that of nickel hydrogen batteries and about 3.0 times that of cadmium nickel batteries. If it is found that the working time of the lithium-ion phone battery block you purchased is not as advertised or specified in the manual, it may be counterfeit.

Look at the surface and material of the plastic.

The genuine battery has a uniform wear-resistant surface and is made of PC material, with no brittle cracking phenomenon; Fake batteries have no anti-wear surface or are too rough, using recycled materials that are prone to brittle cracking.

Measure the charging voltage of the battery block.
If cadmium nickel or hydrogen nickel battery blocks are used to counterfeit lithium-ion mobile phone battery blocks, they must be composed of 5 individual batteries, with the charging voltage of each battery generally not exceeding 1.55V and the total voltage of the battery block not exceeding 7.75V. When the total charging voltage of the battery block is lower than 8.0V, it may be cadmium nickel or hydrogen nickel batteries.
For original batteries, their surface color and texture are clear, uniform, clean, without obvious scratches or damage; The battery logo should be printed with the battery model, type, rated capacity, standard voltage, positive and negative electrode logos, and manufacturer name. Smooth and unobstructed hand feel, suitable elasticity, good coordination with hands, and reliable locking mechanism; The hardware pieces have no obvious scratches and

Blackening and greening phenomenon.

If the mobile phone battery we purchased does not match the above phenomenon, we can preliminarily conclude that it is counterfeit.
Many mobile phone manufacturers also strive to improve their craftsmanship from their own perspective, in order to increase the difficulty of counterfeiting mobile phones and their accessories, and further curb the proliferation of counterfeit goods. Generally, regular mobile phone products and their accessories require consistency in appearance. Therefore, when installing the battery of a purchased mobile phone, we should carefully compare the body with the battery case? If the color is consistent in brightness and darkness, it is the original battery. Otherwise, if the battery itself is dull and lacks luster, it may be a fake battery.

Observe abnormal charging conditions.

Generally, genuine mobile phone batteries should have an overcurrent protector inside, which automatically cuts off the circuit in case of external short circuits or excessive current to prevent burning or damaging the phone; Lithium ion batteries also have overcurrent protection circuits. When non-standard electrical appliances are used and the AC current is too high, the power supply will be automatically cut off, causing charging failure. Under normal battery conditions, it can automatically return to a conductive state. If we find that the battery is severely overheating, smoking, or even exploding during the charging process, it means that the battery is definitely fake.
