If the external short circuit, the current is too large, automatically cut off the loop to avoid burning or damage the electronic product. The lithium ion battery has an overcharge protection line.

When using an unregulated electrical appliance, the signal current is too large, and the battery is automatically cut off. If the battery is severely generated or smoke, even the explosion is found during the charging, then the battery is fake. of.

3, Performance Identification Measures Typical Battery Performance Usually Battery Working Time is a relatively concept, the rated capacity of the battery should not be less than 95% of the standard capacity, and the minler is 28 days, the lowest is not less than the rated capacity of 60%, 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-ion battery appearance should be neat, there is no extra burr, there is a certain roughness in the outer surface 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 mobile phone battery width, and the corresponding position below the battery electrode is labeled, the barrier material of the battery charging electrode is the same as the housing material, but is not integrated.

5. Comparing the size of the battery capacity to a cadmium nickel battery of 500mAh or 600mAh, the hydrogen-nickel battery is only 800-900 mAh; and the capacity of the lithium ion mobile phone battery is generally between 1300-1400mAh, so the lithium-ion battery is fully electrically used. Time is about 1.

5 times the hydrogen battery, and it 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.

When you resolve the true and false batteries, you often ignore a small detail, that is, the battery's touches. Because of the true mobile phone batteries of various famous brands, they are mostly annealing, should be matte, not shining, so according to this, it can be initially determined to determine the true and fake of mobile phone battery.
