Laptop battery stats

I’m having some issues with my battery shutting down at 40% (unrelated to ClearLinux) and am trying to find some programme, like upower, to give me some detailed specs on its performance. Any ideas what I can use on this OS?

Older batteries typically have voltage drops at higher battery levels and so the machine just fails to run. We do have upower2, so you can run upower from the cli.
