{
  uint16   Availability;
  uint32   BatteryRechargeTime;
  uint16   BatteryStatus;
  string   Caption;
  uint16   Chemistry;
  uint32   ConfigManagerErrorCode;
  boolean  ConfigManagerUserConfig;
  string   CreationClassName;
  string   Description;

电池序列号

 Dim results As String = ""
        Dim batteryReturn As Management.ManagementObjectCollection
        Dim batterySearch As Management.ManagementObjectSearcher
        batterySearch = New Management.ManagementObjectSearcher("root\cimv2", "Select * from Win32_Battery")
        batteryReturn = batterySearch.Get

        For Each baseobject In batteryReturn
            results += baseobject("DeviceID")
        Next

        Messagebox.show(results, "Battery serial:")

就像在 c# 中一样（如果你用谷歌搜索解决方案，不要搜索 vb，搜索 .net 甚至 c#）。见https://stackoverflow.com/a/8946096

（我会使用http://msdn.microsoft.com/en-us/library/system.windows.forms.powerstatus.aspx - 如果只有电源状态是相关的）
