As far owned a hearing aid, I have to find my way in the tangle of different batteries once. Previously I had the batteries in the orange packaging - durability ca. 8 days. Use always around 16 hours, sometimes less, sometimes more. After reading the various reviews was already clear to me that the service life of the batteries would unfortunately be no longer. Some reviews after, it might look a bit better at the Panasonic. Unfortunately not. The 1st Battery held for 6 days, the 2nd well, the next two depending only 5 days. This will then have a more expensive fun than it already has. I am the last to have gone over, they do not use as much hours a day, free - 5 Days. Perhaps it will indeed be with the other still a positive surprise because so far taken only 5 batteries of the 60 in use. In this case, I add, of course, the star rating.
