Linux Battery Charge Limiter Service

I have a project to control the battery but at the end of the day I needed something that just works. As I'm using auto-cpufreq I removed the TLP and therefore needed this battery limiter. Help planet and your pocket by preserving your laptop battery life.

Create the service

Create systemd service file (/etc/systemd/system/battery-threshold.service) to run as root:

sudo nano /etc/systemd/system/battery-threshold.service

# Add these Aliases to ~/.bashrc to be able to set battery charging levels to 50-60-70-80-90-100.
#(It appears that lower values than 53 will be ignored)
#Requires SUDO access
