My experience of 40+ years, the life is marginally different so therefore the cost is the better factor to use. Kirkland (COSTCo) seems to give me 6 days ± a few hrs consistency with my aids (yours may vary). And they cost about $.17 each.

If you are a Costco member, they rebranded Rayovac batteries and relatively cheap. Rayovac have been consistently the best ones I have used for 312 for the past 7 years. One brand for hearing aid batteries I would avoid is Duracell. They make great batteries in general, but not for hearing aids. I’ve had multiple sizes over the years and their hearing aid batteries are not the best. I would go out of my way to recommend people do not use Duracell for hearing aids.

Considering the cost of the hearing aids worrying about the cost of batteries seems a little unnecessary. But I will agree with others. When it came to reliability Duracell was problematic

#20

When I used Costco they laster 3-4 days. Duracell last 2-3 days which is annoying.

#21

Both my wife and I have been using Duracell 312s for years and have had very good results with them, so our experience has been positive, unlike some others apparently.

In my opinion - Whatever is on sale

Costco is the cheapest and great quality.

Rayovac 312s always seem to give me an extra day over anything else - and I’m a daily streamer. Costco also excellent value per cell. Energizer actually bought the Rayovac Company last year to get their hands on their technology.

I tested several brands and the one that responded best was Duracell.

I currently use Widex Dream 220 and previously GNResound Canta 7 (lasted 12 years!).

The disappointment was Panasonic.

I use Costco batteries from my local outlet in England and they recently changed their supplier to Varta and made in Germany, I have not noticed any difference .

I don’t use 312, but I feel compelled to chime in since I really doubt size matters to the question.
Mine uses the larger 13

Early on my Audi gave me a pack of power one’s that had great life.

At some point I ordered a bulk pack of amazon branded batteries. They were phenomenal. Lasted me a solid week without fail.

When those ran out I ordered a bulk of power ones from amazon. I don’t recall but I believe the date on them was fine… They were garbage, never got more than 4 days or so…it was all over the map. I was very happy when that supply ran out!

I ordered another bulk of amazon branded batteries… getting a solid 7-8 days so far without fail. No, that’s not right, I did have one cell that lasted a day…but I’ve later found that I had some dirt inside the battery compartment so that might be it…
So I’m sold on the amazon brand
Based on the packaging and sticker on each cell, I think they might be Ray O Vac

Ok, I bought some Rayovac Pro Line Advances batteries after my Power One’s dropped down to about 4.5 days. This became very consistent over the past few weeks. I am on day 7 now with my first set of Rayovacs and still going. I am impressed. If I make it to 3:30 today it will be a full 7 days.

#31

Powerone i get pack of 6 for 2$ :slight_smile:

#32

I also have worn hearing aids for years and didn’t find Proline 312 (sold mostly by HA professionals) any better than regular Rayovac mercury-free. Now I’m using Costco batteries and am pleased with their length of service.

#33

I swear by Costco batteries. But I am trying Amazon batteries. So far, so good. Made in U.S.A. per packaging. Good price but Costco batteries are less expensive

#34

Power One … I’ve used them for years with 3 other brands of HA’s; actually, they’re the only ones I’ve ever tried. Since they’re supplied by the V.A., I don’t know about cost, but with my older Widex Dreams, I usually got about 9 days use before the “replace battery” indication. Today, with my newer Phonak M90s, I get only about 5 day’s use before having to replace them due to BT being build into the aids (that’s what I’ve been told) … that creates a bit more battery drain. Seems that 5 days is pretty normal among those whom I’ve asked.

I would just like to take this opportunity to thank all of you that responded to this thread. I never thought the response would be this big. It will be a good thread to look back on for those who ask the same question. Thanks Again
