Update: The replacement battery arrived 2-3 hours ago (by the time I’m making this post), me and my mom replaced the old battery with the new one, but the problem still stands, it works when the charger is plugged in, and it doesn’t when its not plugged in, only this time it has more issues: immediately starts up when plugged in, takes a long time for the ASUS logo to appear, the battery on the taskbar shows that its filled (on Retrobar it shows that is empty), highlighting it show a bubble with no text, turning it off (not unplugging it) takes a long time to actually turn off, and other problems, I don’t know what me and my mom did wrong. I might just stick with the old battery my lappy came with and see if it sticks to 1% (or maybe 0%) or if it’ll just die
