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.
These batteries last a lot longer than the brand my hearing aid manufacturer recommends. Their recommended brand lasts 2-3 days where as these Renata batteries last 4-5 days. I am very pleased with this product and intend to order more.
I'd prefer Mallory batteries, but these do the job.
They came a advertised --I'm happi !
Good product and a good price.
The shipping was timely, the batteries are great. This is exactly the service I have come to expect from you guys. I wish I needed more of what you sell, because I would definitely need you.
