8.1.4
BatteryMode (0x03)
Indicates if capacity information will be reported in mA/
This function selects the various battery operational
modes and reports the battery’s capabilities, modes
and condition.
mAh or 10 mW/10 mWh. When set, the capacity informa-
tion will be reported in 10 mW/10 mWh. When cleared,
the capacity information will be reported in mA/mAh.
Bit 0: INTERNAL_CHARGE_CONTROLLER
8.1.5
AtRate (0x04)
Bit set indicates that the battery pack contains its own
internal charge controller. When the bit is set, this
optional function is supported and the
CHARGE_CONTROLLER_ENABLED bit will be
activated.
Bit 1: PRIMARY_BATTERY_SUPPORT
Bit set indicates that the battery pack has the ability to
act as either the primary or secondary battery in a sys-
tem. When the bit is set, this optional function is
supported and the PRIMARY_BATTERY bit will be
activated.
Bit 2-6: Reserved
AtRate is a value of current or power that is
used by three other functions: AtRateTimeToFull ,
AtRateTimeToEmpty and AtRateOK :
? AtRateTimeToFull returns the predicted time to full
charge at the AtRate value of charge current.
? AtRateTimeToEmpty function returns the
predicted operating time at the AtRate value of
discharge current.
? AtRateOK function returns a Boolean value that
predicts the battery’s ability to supply the AtRate
value of additional discharge current for
10 seconds.
Bit 7: CONDITION_FLAG
8.1.6
AtRateTimeToFull (0x05)
Bit set indicates that the battery is requesting a
conditioning cycle. This typically will consist of a full
charge to full discharge, back to full charge of the pack.
The battery will clear this flag after it detects that a
conditioning cycle has been completed.
Bit 8: CHARGE_CONTROLLER_ENABLED
Returns the predicted remaining time to fully charge the
battery at the AtRate value (mA). The AtRateTimeToFull
function is part of a two-function call set used to deter-
mine the predicted remaining charge time at the AtRate
value in mA. It will be used immediately after the SMBus
Host sets the AtRate value.
Bit is set to enable the battery pack’s internal charge
controller. When this bit is cleared, the internal charge
8.1.7
AtRateTimeToEmpty (0x06)
controller is disabled (default). This bit is active only
when the INTERNAL_CHARGE_CONTROLLER bit is
set.
Bit 9: PRIMARY_BATTERY
Bit is set to enable a battery to operate as the primary
battery in a system. When this bit is cleared, the battery
Returns the predicted remaining operating time if the
battery is discharged at the AtRate value. The
AtRateTimeToEmpty function is part of a two-function
call set used to determine the remaining operating time
at the AtRate value. It will be used immediately after the
SMBus Host sets the AtRate value.
operates in a secondary role (default). This bit is active
8.1.8
AtRateOK (0x07)
only when the PRIMARY_BATTERY_SUPPORT bit is
set.
Bit 10-12: Reserved
Bit 13: ALARM_MODE
Disables the Smart Battery’s transmission of the
BatteryStatus bits on an alarm condition. Will reset to
enabled after 60 seconds.
Bit 14: CHARGER_MODE
Returns a Boolean value that indicates whether or not
the battery can deliver the AtRate value of additional
energy for 10 seconds (Boolean). If the AtRate value is
zero or positive, the AtRateOK function will always
return true. The AtRateOK function is part of a two-
function call set used by power management systems to
determine if the battery can safely supply enough energy
for an additional load. It will be used immediately after
the SMBus Host sets the AtRate value.
Enables or disables the Smart Battery’s transmission of

Returns the pack voltage (mV).
Bit 15: CAPACITY_MODE

Current (0x0a)
Returns the current being supplied (or accepted)
through the battery’s terminals (mA).
