The place where we got our hearing aids gives us complementary packages of batteries but they are 1.45 volts as opposed to your 1.4. They seem to last longer. Do you have 1.45 volt, size 13 batteries?
[This review was collected as part of a promotion.] I have to tell you that I have only tried three of your batteries as I have other batteries which I wish to use first. I do not believe in wasting things. I have quite a large number of other batteries and they are NOT as good as yours but they do suffice for my needs. I also will be asking your company to change the delivery to four months as I don't wish to get loaded down with too many batteries. I will continue to use your batteries as to my way of thinking they are the Best.
