[Q] Galaxy tab pro 12.2 will not charge topic

Recently purchased a refurbished tab pro 12.2 on ebay. First day I got it it had 60% battery, it worked great through out the day and I watched a movie on it before going to bed, after the movie it was below 15%, when I woke up and tried to used it the screen flickered a lot.
The Tablet wouldn't charge and then it completely ran out and will still not charge. I have tried the cable that came with it and a s5 charger as well as multiple charging bricks. Is the battery dead? Anything I can do?

Thanks
