Sounds like you have multiple problems here. First, the display reaction sounds like a logic board issue again (GPU). The battery for some reason has failed. So can you give us some history on this system. Did it get wet as some point? Did it get dropped? Was it used? Also the people who serviced the system before were they an Apple authorized repair shop or just someone who fixes Apple gear? OR did you really go to a Apple Store or sent it directly to Apple? Why I ask is something is not right here. These two different issues shouldn't be happening at the same time, besides this is not that old a system so the battery shouldn't be running on its last legs.
