The lr927 battery is the same as the model 371.

The model corresponding to 371 is AG6 with a capacity of 28mAh, and the model corresponding to LR927 is AG7 with a capacity of 32mAh. LR927 is a bit thicker. The other parameters are the same.

SR927W is better. It has a large discharge capacity, which is suitable for the high current discharge required by the multi-motor operation of multi-function watches. SR927SW has a small discharge capacity and is suitable for single-motor drive of general function watches. Imported SW batteries are high-power and high-current discharge batteries. There is no difference between domestic ones. Looking at the molds, the technology of domestic batteries is becoming more and more mature now, which is not much different from imported ones.

Discharge characteristic curve battery sorting method:

The battery is sorted by the consistency of the battery discharge characteristic curve. The idea is to use the cluster analysis method to analyze the charge and discharge of the battery based on the statistical principle and considering that most of the single batteries in the combined battery work in the best combination state. Characteristic curves, and then quickly sort a large amount of data through statistical analysis software.

The so-called characteristic curve refers to the curve of the battery voltage changing with time during the charging and discharging process. This curve directly expresses the change of voltage at both ends of the battery with time, and indirectly includes battery characteristics such as the change of battery internal resistance and other indicators with time during the charging and discharging process. Indicators such as the degree of polarization can infer most of the characteristics of the battery.
