SBS Commands
FC (Bit 5): Fully Charged
1 = Battery is fully charged.
0 = Battery is not fully charged.
FD (Bit 4): Fully Discharged
1 = Battery is fully discharged.
0 = Battery is ok.
EC3:0 (Bits 3–0): Error Code
0x0 = OK
0x1 = Busy
0x2 = Reserved Command
0x3 = Unsupported Command
0x4 = AccessDenied
0x5 = Overflow/Underflow
0x6 = BadSize
0x7 = UnknownError
17.25 0x17 CycleCount()
This read-word function returns the number of discharge cycles the battery has experienced. The value of
CycleCount() increments when an accumulated discharge is more than Cycle Count Percentage of
FullChargeCapacity() (if [CCT] = 1) or Design Capacity (if [CCT] = 0).
NOTE: A minimum of 10% of Design Capacity change of the accumulated discharge is required
for cycle count increment. This prevents an erroneous cycle count increment due to
extremely low FullChargeCapacity().

17.26 0x18 DesignCapacity()
This read-word function returns the theoretical pack capacity. The default value is stored in the data flash
value Design Capacity mAh or Design Capacity cWh. The data should be entered in the same units as
configured by SpecificationInfo() [IPSCALE].
NOTE: If BatteryMode()[CAPM] = 0, then the data reports in mAh.
If BatteryMode()[CAPM] = 1, then the data reports in 10 mWh.
