range.
BatteryStatus() (0x16)
This read-only word returns the BatteryStatus word.
Output: unsigned integer. Returns the status reg-
ister with alarm conditions bitmapped as shown in
Table 5.
Some of the BatteryStatus flags (Remaining_Capac-
ity_Alarm and Remaining_Time_Alarm) are calculated
based on current. See Table 8 for definitions.
CycleCount() (0x17)
This
charge/discharge cycles the battery has experienced.
charge/discharge cycle starts from a base value equivalent
to the battery's state-of-charge, on completion of a charge
cycle. The bq2092 increments the cycle counter during the
current charge cycle, if the battery has been discharged
15% below the state-of-charge at the end of the last charge
cycle. This prevents false reporting of small
charge/discharge cycles.

unsigned integer. Returns the count of
Units: cycles
Range: 0 to 65,535 cycles; 65,535 indicates battery

Granularity: 1 cycle
DesignCapacity() (0x18)
This read-only word returns the theoretical capacity of a
new pack. The DesignCapacity() value is expressed in
mAh at the nominal discharge rate.
Output: unsigned integer. Returns the battery ca-
pacity in mAh.
Units: mAh
Range: 0 to 65,535 mAh
DesignVoltage() (0x19)
This read-only word returns the theoretical voltage of
a new pack in mV.
Output: unsigned integer. Returns the battery's
normal terminal voltage in mV.
Units: mV
Range: 0 to 65,535 mV
SpecificationInfo() (0x1a)
This read-only word returns the specification revision
the bq2092 supports. It is typically set to all zeros to
represent non-Rev 1.0 compliance to the SMBus speci-
fication output: unsigned integer.
ManufactureDate() (0x1b)
This read-only word returns the date the cell was manu-
factured in a packed integer word. The date is packed
as follows:(year - 1980)
512 + month
32 + day.
