Started to cut the case open. Painting mask, rubber gloves, safety glasses, hat. Glad there was no one to take a picture of me.

I had bought this HF tool when they were on some super sale...was less than $10 as I recall. Never had a need for it until now. Cuts pretty good. I'm not so hot at cutting a straight line, even when using the edge of the tool along the edge of the battery as a guide. Not quite sure how that happens.



Then the bit snapped. Of course, in our current C-19 world...do I have a spare? I do not. Are any of the stores that would have one open? They are not. So I guess I'm done with battery work for the night.



As a note to anyone who might do this same job later....the bottom of this case is not the same material as the sides. Almost seems like a poured material of some sort. When center punching it, or drill holes, it chips and flakes apart to a small degree. Makes a fair amount of dust when cutting it, so I kept a vacuum handy. Doesn't smell too good either.
