This tool messed my battery

[Migacz85]

Hi, So I wanted to run this command with --help flag. But instead it just run. Immediately after % of my battery disappeared and when I run it again it show up again. But... oddly enough when my battery is discharging now sometimes the number will go up by 1% and then drop by 1 % all that when the laptop is unplugged.

What this tool did when run without parameters?
How can I revert what this tool did?
Thank you...
