hp x360 battery dies at 60% and is unable to calibrate properly

i replaced my laptop battery a few months ago (near the end of 2022) due to having a faulty battery (it would only work when plugged in). since getting this (non-hp) battery, it wouldn’t calibrate and i thought nothing of it as it charged from 0-100 completely fine. since then, it’s been shutting off way too quickly (first at 15, then 20, then 40, now 60) and isn’t able to drain to 0% so i could retry calibration. is there a way to fix this without getting a new battery?? i’m quite adamant on keeping the battery as it’s still well functioning for that remaining 40% i can use along with the fac
