Battery swelling on repaired unit

A little over a year ago, I had my 2021 Blade 17 repaired for multiple issues, among them screws popping out of the bottom (which I learned was a symptom of a swollen battery). Even with the warranty expired, it cost less to repair the machine than to buy a new one, so I sent it in. When I got it back, it seemed as though every issue had been fixed; I was satisfied. However, as I returned to using it, I noticed that the battery life had substantially decreased. Now, the screws are popping off again - something that took four years to happen the last time (as opposed to the one after it was repaired). I could send it in for repairs again, but if the problem with my computer can’t be fixed, it’s difficult to see the point in it. What exactly am I to do here?
