This is pretty outdated. The best care for a battery is try to keep it at 50%. The absolute best way to use a battery would be keep it between 49-51%, which is obviously impossible, so people say keep between 20-80, the closer you get to extremes, the more damage it does to the battery (with fully dead being by far the worse)
