Pay attention to capacity and anti-counterfeiting when purchasing mobile phone lithium batteries

There is a lot of news about the explosion of mobile phones, and fake batteries are the culprit. Currently, the batteries used in mobile phones are mainly lithium batteries. Experts remind consumers to pay attention to the following points when choosing lithium batteries for mobile phones: First, the general capacity of nickel-cadmium batteries is 500mAh or 600mAh, and nickel-hydrogen batteries are 800-900mAh; while the capacity of lithium-ion mobile phone batteries is generally 1300~1400mAh. Therefore, the use time of a lithium battery at full charge is about 1.5 times that of a nickel-hydrogen battery and about 3.0 times that of a nickel-cadmium battery. 2. Look at whether the wear-resistant surface of the real battery is flat or not, using PC material, there is no brittle cracking phenomenon; the counterfeit battery has no wear resistance or too rough, and the use of recycled materials is easy to break and crack. The surface color and texture of genuine mobile phone batteries are clear, uniform and clean, without obvious scratches and damage. The hardware has no obvious scratches, turns black, or turns green. The color of the bottom case of the battery is the same as that of the phone body, and it works well with the phone. This lock is very reliable. The original battery label should indicate the battery model, model, rated capacity, standard voltage, sign and manufacturer's name. 4. Look at the protection device. The battery of a genuine mobile phone should be an internal overcurrent protector. In the case of an external short circuit, if overcurrent is caused, the circuit will be automatically cut off to avoid burning or damaging the mobile phone. If the battery is found to overheat, smoke or even explode during the charging process, it must be fake. 5. Look at the anti-counterfeiting signs such as the original Nokia battery sticker hidden under the obliquely printed Nokia word. The Motorola battery anti-counterfeiting trademark is diamond-shaped, and it flashes three-dimensionally regardless of angle. On the contrary, the anti-counterfeiting marks are dim in color and lack three-dimensionality, and may be counterfeit. If nickel-cadmium batteries and nickel-metal hydride batteries are used to counterfeit lithium-ion mobile phone batteries, they must be packaged with 5 batteries. The charging voltage of a single battery generally does not exceed 1.55v. When the total charging voltage of a battery is lower than 8.0v, it may be a nickel-cadmium battery and a nickel-hydrogen battery.
