Size 312 Extra Advanced Mercury Free Hearing Aid Batteries (80 Batteries)

These batteries are the exact same as we were purchasing at retail Stores and from the audiologist. But they are less than half the price. They have great expiration dates and hold a charge longer than the ones we got at retail. The service is great through this company and were delivered even faster than the estimated delivery date.

Unable to rate recent order (order delayed). Based on my 1st order I would give Rayovac Batteries a review of "5 Stars". All batteries worked efficiently; ordered other brands in the past and some batteries were dead!

I was SO thrilled to find these 312 hearing aid batteries that DO NOT COME IN A CHILD-PROOF PACKAGE! Ever since the battery companies have started using the new safety packaging I struggle to get the package open and have cut myself on one occasion. I ordered from this seller for two reasons: reasonable pricing and the non-child safety packaging. The order came quickly and in good condition.

They are just what I need for my hearing aids. The pack lasts me about eight months. They came quickly and the price for the amount in the package was good

Great batteries. Mom prefers these as they last a long time, about four to five 16 hour days, and they are economical. New PROBLEM: the last order arrived in CHILD RESISTANT PACKAGING. Mom cannot possibly open those packages by herself. I wore out a pair of scissors cutting through the tough poly carbonate packaging, maybe I should have used a bolt cutter instead, they are really tough to cut open. The previous four orders all arrive in regular packaging and worked perfectly well for mom. A followup on March 28,2026 We are finding some dead batteries in the latest order. When Mom replaces her hearing aid batteries she does not always wait for the chime indicating that hearing aid is working well. Some days Mom had trouble hearing all day long after putting in brand new batteries. When I finally checked her hearing aids I found one battery was dead even though Mom had put in new batteries that morning. It is possible that Mom simply mixed up the old and new batteries, that has happened before. When I pulled up a new battery, and let it breath for 5 minutes before installing it, that new battery was dead too. The second new battery that I tried was good and both of Mom's hearing aids worked as normal again. I am ordering a new package of batteries from another source because this last order is not reliable enough for Mom to be able to change her hearing aid batteries by herself. This is too bad as the first four times we ordered these batteries they were great. This fifth order is junk, what changed?

I’m 87 years old and trying to open up these hearing aid batteries are impossible, even trying to squeeze the scissors tight enough to cut through the plastic is more than difficult… when someone is able to cut through it, it also drops multiple small sharp pieces of plastic on the floor which are just as dangerous for children if they pick them up. I also don’t think anyone wants to carry sharp scissors with them when they leave their house, which makes it all the more difficult to replace a battery when you’re not home. There must be a better way, this way hinders more people than it helps!

Good battery excellent performance

These hearing aid batteries are not good. I went through 5 packs to get one that worked. Not worth the money I paused for them.

Doet wat het moet

Ok

Produto confiável, durabilidade média dentro do esperado.

Die Ausdauer ist gefühlt doppelt so lange wie von herkömmlichen Batterien vom Akustiker.

Yes. Longest lasting batteries
