As the owner of an Acer Nitro 5 (AN515-57), I wanted to extend my battery's lifespan by limiting its charging capacity to 80%. Unfortunately, Acer doesn't provide an official solution for this on Linux. However, we can still achieve this functionality.
The <a href="https://github.com/frederik-h/acer-wmi-battery">acer-wmi-battery</a> repository provides a custom kernel module for this feature. However, using the alternatives below is recommended so the module is rebuilt automatically when the kernel is updated.
You can use this <a href="https://github.com/Diman119/acer-wmi-battery/tree/dkms">fork with DKMS support</a> or check repositories for packages providing this module, such as the <a href="https://aur.archlinux.org/packages?O=0&#x26;K=acer-wmi-battery-dkms">AUR</a> on Arch Linux (DKMS) or <a href="https://copr.fedorainfracloud.org/coprs/asan/acer-modules">Copr</a> on Fedora (akmods).

The <code>health_mode</code> value sometimes resets to 0, disabling the feature. Running the command below configures the module to always load with the <code>enable_health_mode=1</code> parameter on boot.
<div class="remark-highlight"><pre class="language-bash command-line"><code class="language-bash">echo "options acer_wmi_battery enable_health_mode=1" | sudo tee /etc/modprobe.d/acer-wmi-battery.conf
