These hearing aid batteries are replacement batteries for size 312 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.
I had to order online because of distancing...these batteries are exactly right and mailing time was short. Good job.
Fast, reliable, and cost effective.
As always from Battery Mart
Good price, fast delivery.
These hearing aid batteries are half of what the hearing aid stores charge. Having gotten a sales price as well puts them at a rediculous price, pennies on the dollar.
Having to wear hearing aids is not fun and is very expense not to mention having to buy batteries all the time. Battery mart has sales that allow me to buy in bulk and save a lot of money that helps me financially bwing disabled and on a small fixed income. Thank you Battery Mart.
I was more than pleased. It was my first experience with BatteryMart. I chose regular first class mail for my delivery and was told to expect and 8-10 day delivery period, which I was fine with. I received an email that my order was shipped the next day and two days later, there they were in my mailbox. I've use Rayovac batteries in the past but thought I'd try the Renata this time. I'm hoping the quality is as good, or better, only time will tell. But that no reflection on the performance of this company, whom I will use again.
