How do I get an OEM replacement battery for my razer laptop?

I have an Early 2021 Razer Blade 15 and I noticed that the battery has swollen to the point that my touchpad no longer clicks. I tried looking on the razer website to buy replacement parts but it's really hard to navigate/I'm not sure it's possible. I submitted a ticket, but I can't mail my laptop in because I use it every day. I'm an electrical engineer and can replace the part myself, I just want to get a OEM battery instead of an aftermarket one.
