iPhone 13 Pro Max- Swollen Battery

My phone has been acting up even though the battery health is 87%. It keeps turning off, the battery will go from 10 to 100 or 80 to 10 percent. The battery is also swollen and the screen is literally lifting. Im not sure when it started lifting or getting swollen. But it's been around two weeks since I notice my phone turning off and on. My phone has no cracks and it's not damaged. Can I replace the battery?
