What is capacity? What is pressure drop?

In the manufacturing process of the battery, the actual capacity of the battery cannot be completely consistent due to technological reasons. The process of classifying the battery by capacity is called sub-capacity through a certain charge and discharge system.

In the manufacturing process of the battery, the actual capacity of the battery cannot be completely consistent due to technological reasons. The process of classifying the battery by capacity is called sub-capacity through a certain charge and discharge system.

The battery shall be qualitatively charged to more than 80%, and the no-load voltage of the battery shall be measured. The 5W/2W battery is used as a load to connect the positive and negative terminals of the battery. The switch is used as an open circuit of the battery, and the device of the path is connected in series. The voltage drop is not more than 0 5 seconds after the switch is turned on. 4V, which is qualified mainly for testing the battery load performance.
