Well-known
My guess, Chuckroast, is that is what Don will do when I send my M5. I suspect I will use the alkaline and see how it goes. Othewise, I will follow in your footsteps with the dummy adapter and a silver oxide battery. My concern is that I've tried that before. I had to file down the adapter in order to get it in the battery well with the battery . The cover never did screw in flush by a long shot.
OK, i just checked my M5. With the adapter in place, the battery cover does not thread all the way in and does stand slightly proud of the body. However, it's really a small amount - perhaps 1-1.5 millimeters or so. This is considerably less than the base height of the strap lugs and does not interfere with any of the camera functions, nor does it get in the way of slipping the camera into my Mr. Zhou half case.
I consider this to be a very minor thing by comparison to the benefit of using silver oxide batteries.
Just for fun, I put in one of my remaining silver PX625s to compare and - while it does thread in completely - the difference is quite small.
I will continue to look for a thinner adapter, however. Supposedly, you can also use #9 O-Rings to hold the smaller batteries in place, but I've not tried this myself.
