I have had my E-PM2 since Week 1 of launch (Nov 2012?). I charged up 4 batteries, including the original BLS-5 and some old BLS-1 and went on my trip. E-PM2 doesn't power on with any of them! With the BLS-5 it says "NO CHARGE" or whatever in red on the LCD. Thankfully I had brought the G5 as well... I get home, throw all batteries back in the charger including the OEM original BLS-5 with original charger that came with the E-PM2...same thing! What gives?? Camera worked perfectly since new....now it thinks all fully charged batteries are dead???
