Battery drops to 0 from 46% despite having equal design and full charge capacity

I bought a used dell latitude e7450 yesterday. The laptop works fine except the battery drops to 0% from 46% really quickly and it shuts down without warning. The battery report says that the design capacity and full charge capacity are both 38,850 mWh which does not seem to make sense. I am attaching the battery report with the post in case additional information is required.
