How to identify the type of battery

How to identify battery type and compare battery capacity. Generally, nickel-cadmium batteries are 500mAh or 600mAh, and nickel-hydroxide batteries are 800-900mAh; the capacity of lithium-ion mobile phone batteries is generally between 1300 and 1400mAh, so lithium-ion batteries are about 1.5 times longer than nickel-metal hydride batteries when fully charged. It is about 3.0 times that of cadmium-nickel batteries. If you find that the lithium-ion cell phone battery block you bought does not work as stated in the advertisement or manual, then it may be a counterfeit. Look at the plastic surface and plastic material. The genuine battery has a uniform anti-wear surface and uses PC material without brittle cracks; the fake battery has no anti-wear or too rough surface, and uses recycled materials, which is easy to be brittle and crack. Measure the charging voltage of the battery block. If a cadmium-nickel and nickel-hydrogen battery block is used to counterfeit a lithium-ion cell phone battery block, it must consist of 5 single batteries. 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 cadmium-nickel and nickel-hydrogen battery block. Regarding the original battery, the color and texture of the battery surface are clear, uniform, and clean, without obvious scratches or damage; the battery model, model, rated capacity, standard voltage, positive and negative signs and manufacturer's name should be indicated on the battery logo. The hand feels smooth and has no blockage, suitable for air tightness, good hand feel, and reliable locking; no obvious scratches, blackening, or greening. If the mobile phone battery we bought is inconsistent with the above phenomenon, we can preliminarily conclude that it is fake. From their own point of view, many mobile phone manufacturers have made efforts to improve their technical level and increase the difficulty of counterfeiting mobile phones and accessories, thereby further curbing the phenomenon of counterfeit parallel imports. General mobile phone products and accessories must have the same appearance under general requirements. So if we bought the battery on the mobile phone, should we carefully check the body and the battery shell? The color, if the color is the same light and dark, it is the original battery. Otherwise, the battery itself will be dim and may be a fake battery. Observe abnormal charging conditions. Generally speaking, there should be an over-current protection device inside the battery of a genuine mobile phone. When an external short circuit causes excessive current, it will automatically cut off the circuit to prevent burnout or damage to the phone. Lithium-ion batteries also have an over-current protection line. When using non-standard electrical appliances, the power will be automatically cut off when the current is too high, causing the charging to fail. Under normal conditions, the battery can automatically return to the on state. If we find that the battery overheats, smokes or even explodes during the charging process, it must be fake.
