Calculator HP 19 B II - replacement of broken part

When chaging the batteries of my HP 19BII I broke the "door" of the compartment of them. For this reason my equipment doesn't work any more because it is not possible to have it well adjusted in its place. How can I get this small piece to have my HP to work again?. In Brazil, where I live, I couldn't find this piece to replace the one which is broken. As you know it is an old model and the replacement of its parts is not easy to find.

    I have the same problem. You are screwed. The only thing that I found that works is using a lot of tape

I had the same problem and fixed it using a small woodscrew and washer to hold the battery cover in place. The screw is 10 milimetre in length with a 5 milimetre head which I have screwed into the calculator case in the gap where the missing edge has snapped off. I inserted the batteries and held the cover in place whilst I tightened the screw and washer so they overlapped the battery cover but held it in place.
To create the hole in the case, I used a very sharp nail as a nail punch, held the HP19BII in between my knees (to allow movement in case I hit it too hard) and tapped the nail into the plastic until it was fully pierced. I then wriggled the nail around to make the hole big enough for the screw to enter. NOTE - don't use a long screw as it might reach too far inside and damage the electronics.
Works a treat for me!

Seeking HP 19B II battery door

HP doesn't sell spare parts for these calculators any more. If the door is the only part you need and the parts of the case opening that hold the door in place are still good, you could make a replacement door.
See the thread about making a battery door for an HP 28S (which uses the same case design as the 19BII).

Does the HP 19Bii use a back-up battery other than the 2 size N batts that go in the back

There is no backup battery as such. The 19Bii uses three N-cell batteries. If only two drop out when you turn the calculator over, tap it against your palm to get the third one out.

The batteries keep popping out when I open the case.

Your battery door or surrounding casing is broken. It's a common problem with this model (especially for units with the side battery door). Unfortunately, your only options are to tape the door shut or get a new calculator. If only the door, and not the casing, is broken you can try to find just the battery door.
