iFixit Battery Replacement Rapidly Discharging

I have a month old battery replacement I purchased for my Macbook. The battery can be at any larger state of charge, go to sleep, and then instantly report a 7% charge upon waking. Here's a screenshot of the Activity Monitor to show the instant drop off (notice the vertical line in the battery state of charge in the bottom right):

Is the battery shorting out somehow? Is it something I can repair?

Indeed this is new with the new battery. Never saw this behavior with the original battery.

Unless you had similar problems with your old battery, nothing should cause such a sharp drop except a faulty battery..ask for replacement.
