The RemCap
ing capacity of the cell before any empty compensation
adjustments are performed. The value is stored in terms
of FVh and must be divided by the application sense-
resistor value to determine remaining capacity in mAh.

prevents large jumps in the reported value caused by
changes in the application such as abrupt changes in
load current. The register value is stored as a percent-
age with a resolution of 0.0039% per LSb. If an 8-bit SOC
value is desired, the host can discard the lower byte and
