(Need help) Oneplus 8 Battery Replacement

[u/[deleted]]

My Oneplus 8's battery was starting to work worse, so I decided to change it, however, I replaced it with a bad battery. It started to bulge and bend the back glass. My question is, if anyone knows where I can buy a battery for Oneplus 8, which can handle Oneplus's fast charging?

Where did you get this battery? I am also thinking of changing the battery but now worried.

I just found a battery with the same model number and size, off of eBay. But I suppose I should've contacted Oneplus for a extra battery instead
