Battery on Razer Blade 2016

I had my Razer Blade 2016 (GTX 970M) since its launch and it has served me well in those years. Had a lot of fun time gaming and everything, and used it to its potential in engineering applications in college as well. Bad thing is, the battery got massively inflated, I'm talking about 30% bigger. One of the corner screws popped out of its hole and I have no idea where it is. As I tried to open it, the other screws practically flew out on the bottom side. Seeing that its been a good 2,5 years, I am wondering if getting a replacement battery is worth it at this point, or if I'm better off buying a new laptop with updated cpu + gpu. I removed the battery out of the laptop and pretty much just sitting connected to UPS power so I don't damage the laptop. Honestly have no idea what to do, any and all help appreciated, thanks.
