Nothing much to do I'm afraid...
If a correcgt battery door can do, get a second hand calculator on ebay. 28C's cand 18C's can be quite cheap. If not, get another 19BII... It's a hell of a machine, would be a pity to part with it.

I have a 19Bii with a feeble door that still works, but I use two large rubber bands around the case and over the door to relieve stress on the door itself during use. I think that really strong rubber bands would also work on a poor or broken door also.
One other major fix (since it is trash otherwise) is to buy brand new batteries and hot weld (or hot melt) glue over the case door while mechancilly holding it with some type of clamp. This would extend your 19Bii for 6-12 months depending upon use. Then remove glue by softening if possible and repeat. Will work at least once (first time) anyway.

I used that model glue/solvent someone recommended here once. Tenax, or some such thing. Anyway, it fixed the chip in the case, and held for quite a while. Of course, I had the chip that came off the case. If the chip is missing, don't know.
Also took one apart once. It seems to be a one way operation. There are approximately 15 gazillion little plastic weldments, and when they break, they break down in the inaccessable areas.

If you want a quick-dirty-functional solution, I've found hot-melt glue solves a LOT of problems. It holds things together well, but is removable later, usually without damage to plastic, metal, glass, and other smooth surfaces.
So, you could use HMG to hold some batteries in place, and later remove the glue, by peeling, when you need to change the batteries.
Obviously, this isn't a good solution for the serious collector wishing to keep a calc in pristine condition.
