Battery Health Charging extension sets the limit of battery charging to maximize battery health mainly for Asus laptop. Since users usually keep their AC adapter connected while using their laptop, the battery is often in a state of high-power(98-100%) for extended length of time which causes a reduction in battery life. Similar to the MyAsus app on Windows OS, you can set the limit to stop charging at one of the 3 following modes.
1. Full Capacity Mode (100%): Battery is charged to its full capacity for longer use on battery power.
2. Balanced Mode (80%): Stops charging when power is above 80% and resumes charging when power is below 78%. This mode is recommended when using the Notebook on battery power during meetings or conferences.
3. Maximum Lifespan Mode (60%): Stops charging when power is above 60% and resumes charging when power is below 58%. This mode is recommended when the Notebook is always powered by AC adapter.
Compatible with Asus laptops and probably other which has only charging stop threshold and doesn't have charging start threshhold.
You can simply check if your device is compatible, and have the following node by executing this in terminal.
ls /sys/class/power_supply/BAT0If you find a node name charge_control_end_threshold and do not find node named charge_control_start_threshold then this extension is compatible with your device.

The service installed is a simple systemd service which on every boot changes the permission of "charge_control_end_threshold" so that users can edit it without root privileged.
