ASUS Battery Health Charging allows limitation of battery charging, which continues working even if the laptop is powered off.

From the GitHub page:

The goal is to replicate the functionality of the ASUS Battery Health Charging utility for ASUS laptops on Windows which aims to prolong the battery's life-span. This has been reported to only work with some ASUS and Lenovo ThinkPad laptops only. For Dell systems, see smbios-utils, particularly the smbios-battery-ctl command, or install it using your package manager. For other manufacturers there is also TLP.
