Overall Feedback:
82% positive
69% appreciated the broad compatibility
The battery lasted for 7 days and 5 hours.

73% praised the long-lasting battery life, while 27% experienced shorter duration
Three batteries from my second 8-pack did not work properly.
The hearing aids beep 'low power' every 15 minutes during the last 12 hours of use, which is frustrating.
72% liked the ease of recharging, but 28% found it slow
I find it convenient that these batteries come in small re-sealable dispenser cards holding eight batteries, which I can always carry in my shirt pocket without worrying about losing any while carrying them around.
I used the first battery from the package and it lasted for 7 days plus 5 hours. I wrote the day and time I put it in my hearing aid.
All the batteries in our first pack were dead.
79% liked the durable battery construction, but 21% experienced premature wear
I got a full week out of the batteries, which is the best I have ever heard from those using my type of aid.
When I first installed the batteries, they worked fine, but they do not last as long as proline batteries in my Oticon hearing aids.
74% appreciated the easy-to-use design
I wrote the day and time I put the battery in my hearing aid and it lasted for 7 days plus 5 hours.
