I have two indentical batteries for my Lenovo; I received them both the same day, but started only by using one of them at the beginning.
I'm having a problem right now with one of them, and I would like to know which one it is. As they look-alike I have no idea which-one was the first I installed and which one was the second.
Is there a tool in Windows 7 that displays the date at which the battery was first used ? I tried with Powercfg -energy in the PowerShell, but no date is available .
