I did provide the official explanation for the changed camera behaviour from the firmware update for whatever you want to make of that ;-). That model has been used and available since 2006 and is still in use with some current models of course. You will see subtly different marked versions in circulation and genuine production has come from at least two different manufacturers/countries that I am aware of. There are different power ratings markings (on some non-genuine ones) too. There are many tens of thousands of the originals in circulation, there having been 30,000+ M9's for a start. Those numbers are tiny compared to the volume production for the big brands of course. One recent comment elsewhere I saw was that leaving the (non-genuine) batteries for longer on the charger past the nominal fully charged indication made them then show as charged fully in the camera. You could try another charger too if you were in a mind to investigate?
