My case was glued or welded together. I thought it was going to break elsewhere first

No need to remove the board. Just use a screwdriver to pop the battery connector off

In at least some of these meters, the caution label has been applied upside-down, so that it covers the screw holes.

The top of the panel has two tabs engaged (can be seen by carefully examining photos above). After screws are freed, lift the bottom edge first to allow tabs to disengage. Also, routing of battery clip wires is critical; take care that they clear the case edges.

I had a spring in mine, and when my grandson took it apart to change battery, I don’t know where the spring came out
