OMD: 3rd party battery users

I don't think the communication level is quite the same. I was using one of the third-party batteries today and it died quite abruptly, without triggering the camera's low-battery warning. If I had been in the middle of a card write when that happened, I would have lost shots and might have corrupted the memory card. Unless I discover for sure that this was just a fluke, I'm going to start changing the third-party batteries as soon as they get down to the one-third-segment level on the battery meter.
