Too late smile look at the picture, that's already a regular user replaceable battery right there smile

In fact , it looks very close to hotel door lock battery packs "Saflok 54240 6V Lithium" which are commonly priced under $10, even as low as $4

The connector might be different though, not a "Molex Micro-Latch (51065-0200 housing + 50212-8100 connectors)"
Some other PLBs use 9volt packs

I'd bet wherever you live there is a small shop (or a person) that would take such a small job for well under $150
