Rayovac Size 10 Hearing Aid Batteries, 8-Pack 10-8

I have used Rayovac hearing aid batteries for several years and have not found any other brand that lasts any longer as a rule. However when I received some Rayovac packages at my local drug store last fall that had a short service span, I sought a source for batteries less apt to have been aging in the retail inventory and delivery chain. I was pleased to find that these could be purchased directly from the manufacturer. I was also pleased to see them marked: "BEST IF USED BY 03/18" which is a later date than any I have purchased in a store.

After using a variety of domestic and foreign-made products, I happened to buy a pack of Rayovac batteries. I have been sold on Rayovac ever since. They outlast other batteries and are totally reliable, so much so that I can predict to the day and part of the day when I will need to replace them. And, both batteries in a set more often than not die within an hour or so of each other.

I appreciate the RayOVac batteries I receive quarterly for my hearing aids. They seem to last much longer than the ones I purchase in any store. It is so convenient having them shipped to my home address. Another reason for my appreciation is the advice I received on how to let each battery 'breathe' before inserting into the aids. Thanks RayOVac

This battery really last longer than other brands. The one thing that I do not like in the packet is that, there is one or two batteries that does not work or defective. It did not happened once but more than a couple of times. Hopefully this could be remedied.

These batteries work fine. I wish they were even longer lasting, but they seem as good or better than any others I have tried. You really do need to give them some time in the air to wake them up, otherwise they sometimes do not work from the start. I find blowing on them works well and with that routine, I have had no "duds".

I have been timing the RayOVac battery, as compared to other brands, and find it does last longer....by about 12 hours, for the very short time (less than 10 days) I have been testing it. However, I think that is not enough time to state firmly that I would buy it over other brands, as yet. And, of course the cost does figure in as a comparison. When other brands are on sale, I will continue to search for the cheapest, yet longest lasting battery I can find.

Sorry to say that I wanted these batteries to last longer than the ones I got from my audiologist but it is not the case. I placed one battery in the left device on 2/12 and had to replace it on 2/17 and the right device on 2/13 and replace that one on 2/18.

It is June 2025..... These batteries expires May 2024 Really disappointed that nobody bothered to check the expiration date before shipping. These are for hearing aids. They need to be able to work when you get them.

The new child proof packaging makes this product almost useless. The packaging for an older person is almost impossible. Most hearing aids do not say "you are in your car and it is quitting, get your sissors and now fight with the package and get one". or you are at a concert and it goes out and you need to cut the package to get at it. How many leave batteries out where kids can get them compared to how many older people with arthritis, shaky hands, but still on the go need EASY access to their hearing aid batteries. Maybe you should reconsider the design or something. I saved the old packaging and am now reusing it for my convenience, but you design caused more problems then it saved children lives. Think again. I know you will not read or care what I say, but I had to let you know the reality of the packaging. I am writing as a wife that makes sure my husband has his batteries when he needs them. Batteries work find.

Being a very capable senior, I will ask a question, The packaging is so difficult to open, Instructions say use scissors. Very hard to cut through the plastic. No instructiions how to get the batteries out. I like Rayovac, but very DIFFICULT TO OPEN.
