Residual Capacity refers to the amount of electricity that a battery can still store and release after a certain number of charge-discharge cycles or aging processes. It is usually used to measure the remaining effective capacity of the battery relative to its rated capacity (initial capacity) at a certain moment.
Meaning: It is one of the key indicators for evaluating the degree of battery life degradation. It affects the actual usage time and available performance of the battery. It is an important basis for decisions on battery exchange, maintenance, or retirement.
