This is the discharge rate used for the Impedance Track simulation of a voltage profile to determine discharge capacity. It is only used when Load Mode = 0 (constant-current) and Load Select = 6 (user-defined rate).
User Rate-mA is only used if Load Select is set to 6 and Load Mode = 0. If these criteria are met, then the current stored in this register is used for the RemainingCapacity() computation in the Impedance Track algorithm. This is the only function that uses this register.
It is unlikely that this register is used. An example application that requires this register is one that has increased predefined current at the end of discharge. With this application, it is logical to adjust the rate compensation to this period because the IR drop during this end period is affected when Terminate Voltage is reached. The default value is 0.
