The battery of a notebook can be inspected by using the `upower` command.
To use it the tool needs to be installed.
In most [Linux](/wiki/linux.md) distributions this is bundled in a package of the same name.
A usage example is shown in the following command.
It will show the state, voltage, percentage and many other information about a given battery.
This section is based on [a video by eKiwi](https://youtu.be/t9KMFDTb79E) which addresses battery
health.
To find out about a battery, its name needs to be known, which can be done using the following
command.
```sh
upower -i /org/freedesktop/UPower/devices/battery_BAT0
upower -e
```
Alternatively `acpi` can be used to achieve the same.
Afterwards different values like the state, voltage, percentage and many other can be displayed.
Additionally it will show the original capacity (`energy-full-design`) and the current capacity
(`energy-full`), which can be used to determine the health of the battery.
The following is an example command where `<battery-name>` is the name of the batter returned from
the previous step.
This might by similar to `/org/freedesktop/UPower/devices/battery_BAT0`.
```sh
upower -i <battery-name>
```
Alternatively `acpi` can be used to achieve similar but less information.
It will show the state, the percentage and the time to load or unload.
For this run the following command.
```sh
