Not much to say about the M battery. There are a couple of “generic” batteries for the M, personally I don’t understand why anyone with a $5000 camera would think about saving $20 and risk less than 100% compatibility with the camera.
I have never managed to use more than 2 batteries in one day, each get about 350-400 exposures with average image review on the screen.
This is maybe the worlds smallest camera battery. you can easily have two in a jeans pocket without even noticing.
One could wonder why its not bigger, personally I prefer changing memory card more often than 400 images,mostly out of my own irrational fear of the card going corrupt and loosing a days worth of images.. changing the battery at the same time is not a big deal.
Bottom line… if you are a digital M owner, just do it.
