Take it to Apple and find out. My guess is they should replace it, but no one here is able to assure you of what Apple will or will not do.
The charge level that is important is the full charge level - what you see when the battery has been fully charged. If that is less than 80% of the maximum charge level of a new battery, then they should replace it for you.
