These Sony hearing aid batteries are replacement batteries for size 13 hearing aid batteries. These hearing aid batteries are 1.45 volts. There are 6 batteries per package and they have a 3 year shelf life, but when activated (tab is removed) shelf life becomes much shorter.
Purchased for my mother and she states that these battries last just as long as the more pricey ones.
Have ordered batteries from you before and always been happy withem and especially the quick delivery!! Thank you
I am very satisfied with these batteries. They last a few days longer
than my other brands. Also easy to order and can pick up instead of
shipping fees. I'll order again. dottie
Lasts days longer than other popular similar brand batteries.
