You could do it like this:
1. Save the code below as c
Windows\BatteryMonitor.vbs
2. Create a scheduled task that runs once every 30 minutes. It should
execute the following command:
cscript //nologo c
Windows\BatteryMonitor.vbs >>
c
Windows\BatteryMonitor.log
3. Examine the log file c
Windows\BatteryMonitor.log
Note that the battery interface appears to differ somewhat between
manufacturers. The code works on my Acer laptop but it may fail on your own
machine.
Set oWMIService = GetObject("winmgmts
\.\root\CIMV2")
Set cItems = oWMIService.ExecQuery( _
"SELECT * FROM Win32_Battery",,4
For Each oItem In cItems
sOutput = Date() & " " & Time() & ": " _
& "Remaining charge=" & oItem.EstimatedChargeRemaining & "%"
If oItem.BatteryStatus = 1 _
Then sOutput = sOutput & ", Remaining time=" & oItem.EstimatedRunTime & "
minutes"
WScript.Echo sOutput
Next
