It's a very common problem. If you google "hp 28s battery door" you find a lot of discussion.
At one point somebody made a metal band that goes across the back of the calculator and holds the batteries in. They don't seem to be available anymore, but that's basically what I need because my battery door is in decent shape, but the case is cracking at the corners.
