Disassembly requires some brute force, however it should be possible to disassemble with minimal damage.

There are six clips around the main seam that will need to be released, and another one between the "tower" and screw hole on the left in this image.

I recommend cutting up a piece of flat, thin plastic (such as a milk bottle) in to shims. Then once you've lifted up the plastic on the battery, slip the shim underneath to keep the clip up.
-
Even once all clips are released, it takes a good deal of force to separate the two halves of the case.
-
Be very careful when releasing the clip between the tower and screw hole, as a slip here could damage the PCB, preventing repair.

Hi Nathaniel,
I’ve managed to damage the resistors in my battery unit as I pulled it apart, I didn’t notice until I’d replaced all the batteries.
I don’t suppose you have a higher resolution image of the PCB in Step 3? I would like to read the values of the resistors around R42 (near the pink and yellow dots).
Thanks,
Andrew Anderson
Hi Andrew
I'm afraid not. From the image it may be a 510, but no guarantees of that. You may be able to find a high enough resolution image on a search engine.
Just noticed the reduced resolution of the upload, try https://imgur.com/a/Evfjd4x
Thanks Nathaniel that image is better, but I don’t want to get this wrong, its the sort of thing that will wind up overcharging one cell or something and letting the smoke out. I’ll keep looking,
regards,
Andrew Anderson

There's another option:
Completely reverse engineer the whole circuit board to work out what the resistor should be.
