Not dead exactly but not what you would call lively.
My battery failed in the garage during its hibernation period, it gave readings like your one. It was tested and declared DOA at the garage testing it. Get it tested properly and find out the truth. It should read 12.7 volts or there abouts, check the forum for accurate figures.
