Battery information was an OS specific issue that plagued Windows Vista and Windows 7. As long as your battery is good, you shouldn't need to worry. While the link ken provided has legitimate Win 7 drivers, I don't know of any specific instability with them.
You may need to disable UEFI/enable CSM/Legacy and disable Secure Boot when installing Windows 7. You may also need to convert the SSD to a MBR disk prior to installing Windows 7 if you have to make said changes to BIOS settings as well.
