Look at the logo: the logo on the real battery board is clearly printed, while the counterfeit products are copied and printed, and the handwriting is blurred. The "positive and negative" polarity symbols of the real battery panel are directly made on the metal contacts, and the fake ones are made on the plastic case, and some of them have no "positive and negative" symbols at all.
Look at the process: the real battery plate is welded by ultrasonic wave.
The front and rear covers are inseparable, and there is no obvious crack. Fake panels are mostly hand-made, glued together, and will break in half with a little force.
Look at the safety performance: in order to protect the battery and the mobile phone, the regular mobile phone battery panel is equipped with a temperature control switch. If the charging time is too long, the voltage is too high, the temperature rises sharply, and the battery panel heats up, the power supply will be cut off in time to prevent the battery from leaking or exploding. Fake and shoddy battery panels do not have this device, but are welded with an electric soldering iron, and even a small battery dedicated to non-rechargeable cameras is connected in series, while fake lithium batteries, if forcibly charged, may cause an explosion.
Distinguishing whether the mobile phone battery is original can be analyzed from the following aspects:
1, the original battery looks neat, the surface feels comfortable, the inner surface feels smooth, and tiny longitudinal traces can be seen under the light.
2. There are clear manufacturer's words and high-brightness anti-counterfeiting marks on the battery, the battery label is legible, and the battery part number is consistent with the battery type.
3. The battery label adopts secondary printing technology. Seen from the inclined plane under certain light, the color of the bar code part is darker than other parts, and it feels concave and convex by hand.
4. The width of the original battery electrode is equal to the width of the cell of the mobile phone, and the "+"and "-"symbols are marked below the battery electrode. The isolation material between the battery electrode plates is the same as the shell material, but it is not integrated.
5. When the original battery is installed on the mobile phone, it feels comfortable and can be installed freely, and the battery pressing part fits properly and firmly.
6. The metal contacts of the original battery are made of high-quality copper sheets, which will only reflect light when viewed from the front, and will be dim when viewed from other angles.
