Advantages

Why is the capacity of some batteries not compatible with the capacity of a single cell?

This is because the coding capacity of our lithium batteries is the actual capacity, and the capacity of a single cell is the nominal capacity, so the capacity of a single cell may not match the capacity of the coding. During the manufacturing process of the battery, the actual capacity of the battery cannot be completely consistent due to technological reasons. Through a certain charge and discharge test, the process of classifying the battery according to the capacity is called capacity division. The lithium battery coding is to print the battery information on the surface of the battery, that is, to give the battery an ID card. Lithium-ion battery coding content includes basic battery information such as manufacturer, model, production date, voltage, capacity, energy, production batch number, and battery QR code.

Buyers should pay attention to the coding information when buying batteries.
