Where can I buy a battery replacement for G14 GA402 (2022)?

So my battery is honestly pretty terrible after barely 2-3 years, and I'm possibly looking at replacing it. It seems that iFixit has a relatively easy to follow guide on how to replace it so I think I'm mostly set there. The problem is that I'm having difficulty finding the actual battery replacement for my model, as the tutorial links to the battery for the 2021 model. Where can I buy this battery replacement??? Or at the very least where can I get service to get it replaced.
