Apple MR932LL/A-16GB-256GB-SPACEGRAY (Open Box)

Product arrived with minimal scratches/ scrapes. Has a scratch on the front part and the "A" key has popped out of place. When I plugged it in and started using it it all went smoothly until I saw the battery icon had a "X" on it. It didn't retain charge without being directly hooked to a power source. I just came back from the Apple store where the employee helped assess the problem which obviously it was that the battery needed replacement. He put in a work order for a replacement but said it might not be possible to get the part due to how old the battery is (2018 model). It'd would have cost another almost $300 if they can even get the part. I'm so disappointed since I paid for the refurbished laptop in great condition yet its core isn't functional. Why even sell it in the first place? I'd skip the purchase, y'all. Now I have to see if I can return it and get my money back so I can just save up a few more hundred for a new laptop from the apple store where I know it'll be functional and have apple warranty.
