Hello, I just replaced the battery in my Macbook. It will hold a charge for about an hour, drain to about 85% and then shoot down to 7% and continue to die in a quick 15 minutes. I already did all possible resets and other troubleshooting. What else could cause this issue?

It looks like you got a bad one, contact the iFixit store support folks to get a replacement https://help.ifixit.com/category/133-con… In your message link to this question so they can see the CoconutBattery output.
