These hearing aid batteries are replacement batteries for size 312 hearing aid batteries. These hearing aid batteries are 1.45 volts. There are 60 batteries total per box and they have a 3 year shelf life, but when activated (tab is removed) shelf life becomes much shorter.
I have used hearing aids for 3 years. This means I have tried many different brands, with all from acceptable quality to the cheapest ones lasting just hours.
Renata is my preferred ones now, as they are very long lasting. They provides a stable sound quality, witch means that they give a very even power instead of giving all the power at once, so they run flat too soon. I love them , and can wholeheartedly recommend them for resound hearing aids.
I have not used many of these batteries, yet. However, those used seem to be fresh and full strength. The delivery was timely, and received in good condition.
Good product and fast shipping

These batteries last longer than others at a much better price.
