After Unplugging my laptop and got shut down it never charges to any % and shuts down instantly if not in plug

So this strange thing happened today: Had to move to another room and unplugged my laptop to fix the wires etc. After some hour or so it shut down because, well.. it wasn't in charge, and when I put it back in, the Battery always says Estimating in the ubuntu indicato. And INSTANTLY shuts down when I unplug it (even plugged, it shuts down if I do something demanding). I tried close it and charging it while shut down but same thing happens. Also unplugged the battery and replugged it nothing happened It's like battery died in one day. Is that it? Just look to a fresh battery?
