How to understand the quality of 18650 lithium battery 3.7 v
As for the advantages and disadvantages of lithium battery UPS, the general approach is to use the technology of professional equipment to judge, but this special equipment is not available to ordinary users.
1. Simply judge from appearance. Just like the four diagnosis methods of traditional Chinese medicine. First check the consistency of the surface, such as whether the appearance of the lithium battery UPS is deformed or bulged. If this situation indicates that the internal chemical structure of the lithium battery has been destroyed, it must be eliminated.
2. In addition to observing deformation, it is also necessary to observe the presence of liquid leakage, cracks, burning or internal liquid at the screw interface. Generally speaking, these rechargeable batteries are rechargeable batteries with major product quality problems. This batch of lithium battery UPS that only has defects in appearance cannot be selected. It is also not recommended to select batteries of the same model and manufacturer to prevent safety accidents and various malfunctions during use.
3. Internal loads must be accurately measured. If the lithium-ion charging and discharging time cannot complete all normal charging and discharging times, or the battery charging time is sufficient and cannot meet all normal appointment time standards, it means that the battery is already brittle and the normal application of lithium-ion can no longer be considered.

1. Simple surface resolution. Just like the four diagnosis methods of traditional Chinese medicine. First examine the consistency of the surface, such as the shape of the lithium ions rising, deformation or suddenness of the wood. If this situation indicates that the internal organic chemical structure of the lithium ions has been destroyed, it belongs to the team that must be cleared.
