Battery patch help

Hi! I have already installed Catalina on my Asus TP412FA (Core i3-8145U, 8 GB DDR4, Intel HD620, SSD Kingston NVMe 256 GB) and now I would like to fix the battery readings. I tried to use the Rehabman's guide but it's too complicated. Can someone please help me with it. Here is my DSDT (got it from Linux and it's unpatched): https://drive.google.com/file/d/1ZwAuaxL1LmHA8j7YcMYNEPmpEvyJY4Fr/view?usp=sharing
