FullChargeCapacity() (0x10); [0x10]
Description:
Returns the predicted pack capacity when it is fully
charged. The FullChargeCapacity() value is expressed
in either current (mAh at a C/5 discharge rate) or power
(10mWh at a P/5 discharge rate) depending on the set-
ting ofthe BatteryMode()’s CAPACITY_MODEbit.
Purpose:
The FullChargeCapacity() function provides the user
with a means of understanding the tank size of their
battery. This information, along with information about
the original capacity of the battery, can be presented to
the user as an indication ofbattery wear.

RunTimeToEmpty() (0x11); [0x11]
Description:
Returns the predicted remaining battery life at the pres-
ent rate of discharge (minutes). The RunTimeToEmpty()
value is calculated based on either current or power de-
pending on the setting of the BatteryMode()’s CAPAC-
ITY_MODEbit.
Purpose:
The RunTimeToEmpty() provides the power management
system with information about the relative gain or loss in
remaining battery life in response to a change in power
policy. This information is NOT the same as the
AverageTimeToEmpty(), which is not suitable to determine
the effectsthat result froma change in powerpolicy.

Unsigned integer—minutes ofoperation left.

AverageTimeToEmpty() (0x12); [0x12]
Description:
Returns a one-minute rolling average of
the predicted remaining battery life (minutes).
AverageTimeToEmpty() value is calculated based on ei-
ther current or power depending on the setting of the
BatteryMode()’s CAPACITY_MODEbit.
The
Purpose:
The AverageTimeToEmpty() displays state-of-charge in-
formation in a more useful way. It averages the instan-
taneous estimations so the remaining time does not ap-
pear to jump around.

AverageTimeToFull() (0x13); [0x13]
Description:
Returns a one-minute rolling average of
the predicted remaining time until the battery reaches
full charge (minutes).
Purpose:
used by the SMBus Host’s power management system to
aid in its policy. It may also be used to find out how long
the system must be left on to achieve full charge.
