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.
Fair price. Long shelf life. Arrived as scheduled.
I wish you offered mallories in this size, but these work OK and shipping is fine. I'll stay your customer
These batteries fit my wife's hearing aids perfectly. They last as long as the ones she was getting from the hearing aid company.
I would prefer Duracell, but I can't find them on your site.
I have ordered hearing aid batteries from Battery Mart for several years. They always have what I am looking for and ordering online is easy and quick. They ship my order immediately and I receive my batteries within a couple of days.
I recommend them if you need batteries of virtually any kind.

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.
