Enumerate Battery

The following steps describe how to retrieve information about the batteries in the AMT device.

1. Retrieve the list of CIM_Battery elements and examine the following properties:

a. CIM_Battery.BatteryStatus to determine the current status of the battery (such as Low, Critical, or Fully Charged)

b. CIM_Battery.Chemistry to determine the type of battery, such as Nickel Cadmium or Lithium-ion.

c. CIM_Battery.EstimatedChargeRemaining to see an estimate of the percent of battery power remaining.

d. CIM_Battery.FullChargeCapacity to see the battery’s mWh when fully charged.

e. CIM_Battery.DesignVoltage to see the battery’s design voltage in millivolts.

2. Create a reference to each instance of the battery so that the corresponding CIM_PhysicalPackage object can be identified.

3. Use the list of CIM_PhysicalPackage objects to examine the following properties:

a. CIM_PhysicalPackage.SerialNumber to see the battery’s identifying serial number.

b. CIM_PhysicalPackage.Manufacturer to see the name of the organization responsible for producing the battery.
