Laptop utility to tell me what percentage of original capacity battery will still hold?

With Windows 7, my Lenovo laptop had a utility that would tell me what percentage of the battery's original capacity it was still capable of holding.

But now I have Windows 8.1 on it and the version of the Lenovo battery manager that runs on Windows 8 does not give that information. I tried installing the old versions but it refused to install in Windows 8, or maybe it was Windows 8 that refused to allow it to install.

Anyway, is there any utility out there that will tell me?
