Can I get the System Battery Voltage using windows Dll

[Vivek Bhojan]

There is a function "Get System Power Status" under Kernel32.dll, which gives only the system Power Status like On/Off, AC/DC type etc. Can anyone please help me in finding the System Battery Voltage and Current?

Do you really need the voltage level? Or do you only need a indicator for the how much % of the battery level remains. If the latter you can just use the "GetSystemPowerStatus" function, it also returns the % level of the battery.

If not you can use PowerReadACValue; msdn.microsoft.com/en-us/library/windows/desktop/aa372734(v=VS.85).aspx

or PowerReadDCValue; msdn.microsoft.com/en-us/library/windows/desktop/aa372737(v=VS.85).aspx

for all power management functions you can look here: msdn.microsoft.com/en-us/library/windows/desktop/aa373163(v=VS.85).aspx
