[This review was collected as part of a promotion.] Plenty of batteries in the pack, also from a great brand I can trust. My brother in law suffers from hearing loss after being deployed. He is quite thankful to have these batteries on him at all times so he can hear.
[This review was collected as part of a promotion.] Batteries rayocac for my hearing aid. Fit in perfectly and last so long. Easy to put in and take out.
I have used Rayovac size 13 batteries for the past 5 years in my hearing aids and have been quite satisfied with the performance and longevity. The "new" batteries however, are not so great. The old batteries lasted 18% longer in similar temperature and environmental conditions. I will try another package hoping this fist package was a fluke, otherwise I will switch to another brand and try Rayovac again at a later date. Very disappointed.
