1. Compare the size of the battery capacity. The general cadmium nickel battery is 500mAh or 600 mAh, and the hydrogen-nickel battery is also only 800-900 mAh; and the capacity of the lithium ion mobile phone battery is generally between 1300-1400mAh, so the time for the lithium-ion battery is used for a hydrogen-nickel battery.
1.5 times, is about 3.0 times that of the cadmium nickel battery.
If you find that the lithium ion mobile phone battery work hours of the lithium ion mobile phone battery you purchased is not propaganda or the length specified in the specification, it may be counterfeit. 2. Look at plastic surface and plastic material.
The authentic battery anti-wear surface is average, which uses PC materials, no criticism; counterfeit batteries have no anti-grinding surface or too rough, using regeneration materials, easy to scramble. 3. Measure the charging voltage of the battery block.
If the cadmium nickel, the hydrogen-nickel battery block is fake a lithium ion mobile phone battery block, it is not obtained from five monomeric batteries, and the charging voltage of a single battery is generally not more than 1.55V, and the total voltage of the battery block does not exceed 7.75V.
When the battery When the charging total voltage of the block is less than 8.0V, it is possible to be cadmium and nickel, hydrogen-nickel battery. 4.
About the original battery, its battery surface color is clear, average, clean, no scratch mark and damage; battery logo should be printed with battery model, type, rated capacity, standard voltage, positive negative sign, manufacturer name. The hand feels smooth and no blocked, the tight is suitable, good with the hand, the lock is reliable; the five gold flakes are unblocked and black, green phenomenon. If the mobile phone battery we purchased is not in line with the above phenomenon, it can be concluded that it is a fake.
5. Many mobile phone plus manufacturers have also started from their own perspective, and improve the fake difficulty of mobile phones and their accessories through efforts to improve their craftsmanship. Generally, formal mobile phone products and their accessories require the consistency on the appearance.
Therefore, if we put it on the battery battery to buy back, take care of your body and battery undercale. If the color is dark, the original battery is. Otherwise, the battery itself is dull, it may be a fake battery.
6. Observe the abnormal situation of charging. In general, the inside of the genuine mobile phone battery should have an overcurrent protector.
When the exterior short circuit, the current is too large, automatically cut circuit, so as not to burn or damage the phone; the lithium-ion battery has an overcurrent protection line, when using irregular electrical appliances When the sap electrical current is too large, the power is automatically cut off, causing the charge, and automatically recovered to the on state. If we are in the process of charging, it is found that the battery is severely generated or smoke, even exploded, indicating that the battery is definitely fake.
