How effectively quickly identify the lithium battery?

Source: 2020 - 03 - 30 13:58 hits: amateur identification method under the condition of non-professional, can use the following method to identify: 1) Battery capacity is equal, lithium battery lighter than nimh battery, nickel metal hydride batteries. 2) Use the special charger for the battery of lithium battery. If the battery in the process of charging fever, for the nickel hydrogen battery or nickel cadmium battery; If the temperature change is not obvious, that is, lithium battery. 3) Battery to the positive and negative, 'moment' short circuit after use, such as batteries' reactive 'is lithium battery, if the battery is still the' work 'is nickel metal hydride, nickel cadmium battery. Professional recognition method ( 1) With a special tool to identify safety sign in the face of the market increasingly diversified mobile phone batteries and increasingly complex forging technology, some big companies in improving their anti-counterfeiting technology. New nokia mobile phone batteries, for example, is marked on a special kind of lithium, need to use special prism to identify, and only nokia has the special prism. Therefore, with the development of anti-counterfeiting technology, it has been difficult to distinguish between the real battery and appearance. ( 2) Use a dedicated detector to identify battery appearance alone is hard to judge the quality of the battery. To this end, launched a mobile phone battery detector on the market. Battery tester can detect and distinguish the lithium battery, nickel metal hydride batteries, nickel-cadmium batteries and battery capacity and quality of voltage of 2 k - 6. 0 v, the capacity is 1999 mah, with functions of activating, charge and discharge. The whole process is controlled by a micro lithium device according to the battery characteristics, realize the measured voltage, current, capacity, technical parameters, such as digital display. ( 3) Research cell function general standby time, talk time is a relative concept, investigate customer's comprehensive utilization of battery capacity is the length of time, namely, standby time, talk time. In short, the capacity of the battery should not be less than 95% of the standard capacity, 28 days on a full charge, the minimum capacity of not less than 60% of the rated capacity, battery life should not be less than 400 times. If the battery is not in conformity with the above standard, can be judged to be fake. ( 4) Check the battery logo on mobile phone battery packaging shall be marked clearly prescribed by the state trademark, producer name and address, the positive and negative, battery capacity, raw materials, such as rated capacity is an important factor in prices of mobile phone batteries. If there were no marks or incomplete, is that it is relatively low. More importantly, the true battery brand is super glue, it is not easy to tear. And fake batteries, as long as quietly tore it off, can tear up the label. ( 5) Investigate anomalies general quality goods mobile phone battery charging should be over-current device maintenance, when causes such as external short circuit current is too large, should actively blocking circuits, so as not to burn or damage to the cell phone. Lithium-ion batteries have filling line maintenance, when using non-standard electrical appliances, will take the initiative to cut off the power when the current is too large. If in the process of charging, find battery serious heat may smoke, or even explode, that is false.
