DESCRIPTION
DECODE
Cycles
15:0
Cycles. The Cycles register maintains a total count
of the number of charge/discharge cycles of the
cell. The result is stored as a fraction of a full cycle.
For example, a full charge/discharge cycle results in
the Cycles register incrementing by 100%. The
Cycles register accumulates fractional or whole
cycles. For example, if a battery is cycled 10% x 10
times, then it is equivalent to 100% of one cycle.

DesignCap
15:0
Design capacity. The DesignCap register holds the
nominal capacity of the cell. This value is used to
determine the age and health of the cell by
comparing it against the measured present cell
capacity.
