@Volusiano: MrV once again gets top marks for his listening skills! The details of his summary are exactly right! Because I don’t possess his level of technical knowledge, I’m not able to speculate as to why the More devices take different batteries than the OPN S, but they apparently do. And it does seem logical to me that they would require a reset in Genie2 for the calibration of the battery meter and proper charging.
Even after the batteries were correctly installed by my audiologist, however, I was experiencing a funny issue: the HA LEDs would fail to turn green when the batteries were fully charged, but remained in their amber “charging” status. If I removed the devices from the charger and reinserted them into their charging cradles, however, the LEDs would immediately show green. My audiologist sent my devices and the charger back to Oticon for testing. They never did tell either me or my audiologist the results of their analysis, but my More1s have been easily lasting through my 18+ hour days with about 20% charge remaining by the time I turn in and put my aids back in the charger.
