I do not notice any reduction in performance and duration, compared to the extremely expensive Rayovac premium batteries sold by the hearing aid dealership.

Bravo to him, impeccable and fast! I ordered 1/2026 and they expire at the end of 2029! Very good batteries! Thank you agronomist!

Compared to other battery brands, these do not drain when not in use. I have a hearing aid which I use rarely because I also have a cochlear implant in the other ear. The problem I had with other battery brands was that they would drain without using the hearing aid, but with Rayovac batteries I don't have such an issue because they only drain when I actually use the hearing aid

Good batteries for hearing aids, although they run out quickly (I don't know, of course, if it's the batteries' fault or the hearing aids, that is, if they have high consumption).

Reliable and very value for money. For 1.20 euros for the pack of 8 batteries, we don't even discuss it when the same brand with six batteries in stores costs six euros.

Very good and economical. They last as long as the "original" batteries (of the headphone company) and are 5 times cheaper.

I asked for size 13 batteries, you brought me size 312 instead. I asked for a refund and the item back!!! Unfortunately, I am not satisfied with the order, be careful what you put in the boxes

Very good in quality and durability. Perhaps the best in terms of their price. I have been using them for years.

In the measurements, it is not clear whether it still holds up or not, on average it lasts 7-8 days in hearing aids

For hearing aids that I use, they are fine.

At least in our experience, the first set of six that we have tried so far have lasted the same amount of time, maybe even a little longer than other comparable branded ones that have twice the price

Excellent packaging, amazing product at an amazing price. Genuine batteries with a fresh production date. I recommend them with closed eyes and of course, I will buy them again from here next time.

The life of this specific battery is very short compared to the same battery I buy from the store with hearing aids. I didn't buy it through an online store. It's better to pay more and get a guaranteed lifespan.

Known Rayovac quality.. No special recommendations needed. This company is worth it and more.

We have been using these batteries for almost three years, we are completely satisfied and here we found them at the lowest price
