I find several different options for type 14464 replacement batteries for the M* on Web sites.
These appear to be available in the following values: 1600 mHa and 1900 mHa. The "Liica" branded battery presently in my camera is rated at 1860 mHa and the prices differ considerably.
Can someone, please, advise me as to the pros / cons of using a compatible type battery as against the genuine Leica one.
With many thanks,
