Read "time to fully charged"

I am testing several laptops with Windows installed and I need to write code that takes the time (in seconds or minutes) until fully charged - the value that windows shows, as well as the time until fully discharged. The value that indicates how many minutes until full discharge is contained in the PowerStatus.BatteryLifeRemaining Property. I can't find where to read the time until fully charged. I don't want to calculate it because I need exactly the same time that Windows shows. CIM_Battery Methods, Win32_Battery, Win32_PortableBattery and PowerStatus do not provide this information. --- Bat
