7.1.25
Returns the theoretical capacity of a new pack. The
DesignCapacity value is expressed in either current or
power, depending on the setting of the BatteryMode's
CAPACITY_MODE bit.
7.1.26
Returns the theoretical voltage of a new pack (mV).
7.1.27
Returns the version number of the Smart Battery
specification the battery pack supports.
7.1.28
This function returns the date the cell pack was
manufactured in a packed integer. The date is packed
in the following fashion: (year-1980) * 512 + month * 32
+ day.
7.1.29
This function is used to return a serial number. This
number, when combined with the ManufacturerName,
the DeviceName and the ManufactureDate will
uniquely identify the battery.
7.1.30
This function returns a character array containing the
battery manufacturer's name.
7.1.31
This function returns a character string that contains
the battery's name.

DeviceChemistry function returns "NiMH," the battery
pack would contain nickel metal hydride cells. The
following is a partial list of chemistries and their
expected abbreviations. These abbreviations are NOT
case sensitive.
7.1.33
This function allows access to the manufacturer data
contained in the battery (data).
7.1.34
The PS401 includes new SBData functions using the
OptionalMfgFunction command codes. The command
codes 3C HEX to 3F HEX report the individual cell
voltages
converter. These voltages are reported in mV and are
calculated to include compensation for calibration and
sense resistance voltage drops. Only one cell voltage
is measured per measurement cycle (depending on
Run or Sample mode operation.)
Rapid voltage changes will see some variation in
voltages due to the delay of measurement. These
voltage values may be used for cell balancing or other
functions as the Host system may desire
