CIM_Battery class

The CIM_Battery class represents the capabilities and management of the battery logical device. This class applies to batteries in laptop systems and other internal and external batteries.

Important

The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.

SmartBatteryVersion

Data type: string
Access type: Read-only
Qualifiers: MaxLen (64), MappingStrings ("MIF.DMTF|Portable Battery|002.10")

Status

Data type: string
Access type: Read-only
Qualifiers: MaxLen (10), DisplayName ("Status")

String that indicates the current status of the object. Operational and non-operational status can be defined. Operational status can include "OK", "Degraded", and "Pred Fail". "Pred Fail" indicates that an element is functioning properly, but is predicting a failure (for example, a SMART-enabled hard disk drive).

Non-operational status can include "Error", "Starting", "Stopping", and "Service". "Service" can apply during disk mirror-resilvering, reloading a user permissions list, or other administrative work. Not all such work is online, but the managed element is neither "OK" nor in one of the other states.
