Unfortunately, the last batch of batteries for the hearing aids was very disappointing. Usually one battery lasts about one week, but these last only 15-20 minutes. At first we thought the problem was with the hearing aids themselves, but in the end we found that the cause is the batteries. We are very sorry for this experience and hope there will be an improvement in the quality of the product.

Very low voltage on the batteries in the package, even though the expiration date is 2029. So accordingly the headset does not work properly and has no battery life at all.

Although the expiration date is 03.2029, so far out of the 3 packs I opened, only 1 had batteries with power... I'll see about the next ones too

Reliable batteries. More than 10 years of using this particular company for hearing aid batteries. They have not caused any problems whatsoever.

I bought these specific batteries for hearing aids (312) from the official reseller of the company because it was not worth buying them from the local optical and hearing aid stores in my area, so I went on SKROUTZ, found the RAYOVAC batteries, found the official reseller and bought the quantity that I believe will meet the needs of my relative who uses hearing aids.

They work great and their duration is very satisfactory.

Great batteries. No comparison to the price charged by stores for hearing aid batteries, which can sometimes be 5 times more.

Duration is about a week. Not all 6 batteries have the same duration, and if used in pairs, usually one changes first and then the other after 2 days.

The consistent quality of Rayovac at a very good price. They were placed in an elderly hearing aid and they work perfectly for at least 10 days.

Good quality, they last quite a while, although not all of them because there are some defective ones that don't last more than a day. The price is great as well as the packaging

It's great, there is a normal battery life, I bought 5 packs and the 4 that I have used were okay!

For hearing aids, they are value for money, they withstand exactly the same as the much more expensive branded companies at double the price.

I don't know why. Having used this specific battery again, it lasted seven times longer than the ones I bought last time, and unfortunately, I bought too many. With people I contacted in the market, whole batches have turned out to be defective.... Avoid buying especially batches with expiration date 2023-2024
