The SOC
of charge of the cell based on all inputs from the
ModelGauge m3 algorithm including empty compensa-
tion. The register value is stored as a percentage with a
resolution of 0.0039% per LSb. If an 8-bit state-of-charge
value is desired, the host can discard the lower byte and
use only the upper byte of the register with a resolution of
1.0%. The SOC
tion. Jumps in the value can be caused by changes in
the application such as abrupt changes in load current.

The SOC
the battery according to the voltage fuel gauge. The reg-
ister value is stored as a percentage with a resolution of
0.0039% per LSb. If an 8-bit SOC value is desired, the host
can discard the lower byte and use only the upper byte of
the register with a resolution of 1.0%.
SOC
The TTE register holds the estimated time to empty for
the application under present conditions. The TTE value
is determined by dividing the RemCap
AverageCurrent register. The result is stored in the TTE
register with a resolution of 5.625s per LSb.
