Lithium battery product discrimination method 1, check whether there is a security label to see if there is a security label, generally, most of the brand battery will put on the anti-counterfeiting label on the battery case. So pay attention to see if this anti-counterfeiting label is intact, it can also scratch the anti-counterfeiting label cryptographic coating to verify the authenticity. Finally, pay attention to the processing date of the upper machine on the lithium battery.

2. Charging process examination method Generally, there should be overcurrent protector inside the genuine lithium battery. If the external short circuit, the current is too large, automatically cut off the circuit to avoid burning or damage the electronic product.

The lithium battery has an overcharge protection line. When using an unregulated electrical appliance, the sap electrical current is too large, if the battery is severely generated or smoke, even explosion during charging, then the battery is fake. 3.

Performance Differential Method Investigating Battery Performance Usually Battery Working Time is a relative concept, the rated capacity of the battery should not be less than 95% of the standard capacity, the lowest electrical placement 28 days, the lowest is 60% of the rated capacity, the battery life is not Less than 400 times; if the battery does not meet the above criteria, it can be judged to be a fake. 4, all genuine lithium battery appearance should be neat, no extra burrs, the outer surface has a certain roughness and feel comfortable; the inner surface is smooth, and the tight vertical scratches can be seen under the light. The battery electrode is the same as the width of the mobile phone storage battery, and the corresponding position below the battery electrode is labeled, the isolation material of the battery charging electrode is the same as the housing material, but is not integrated.

5. Compare the size of the battery capacity, a cadmium-nickel battery of 500 mAh 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 lithium battery is fully charged. Time is approximately 1.

5 times the hydrogen battery, and is about 3.0 times that of the cadmium nickel battery. If you find that the lithium-ion mobile phone battery block working hours do not have a propaganda or the length specified in the specification, it may be counterfeit.
