[Leica] M8 failure in snow

[Frank Filippone]

Batteries supply less total energy in cold weather than warm weather.  If
the camera uses more energy, then the ( same ) battery lasts less long.
Your M240 are more energy efficient than the SL ( if nothing else, the EVF
takes a lot of energy to run, compared to the M bodies).  

(If you had used an M4 or earlier, the non-battery would have lasted
indefinitely..... !)

The SL battery died after two hours at -40C.  The M240 and MM batteries
never quit.
