Below you can find a very simple shell script that gets information about every battery present in your notebook and shows a summary.
- create a new file (es: /usr/local/bin/battery.sh)
- paste inside the new file the following code

- make the file executable (es: chmod +x /usr/local/bin/battery.sh)
- use the script (from a terminal execute: /usr/local/bin/battery.sh)
