My first concern is that this looks very difficult to remove if the battery begins to swell, as silver-oxide batteries are wont to do. Perhaps that's less likely with single use batteries.

This is one of the reasons why we decided not to have rechargeable batteries! We saw what happened to the Samsung ring.

There is no risk of swelling with Index 01

I thought you might find it interesting to know that it’s “wont” instead of “want”, when saying “wont to do”

Also: I agree with your concern

Should be relatively straightforward to remove with a small wire cutter.
