I use batteries all the time . They dont last as long as Energizer but they do provide . Expensive for an everyday user to say the least . Last about 2 weeks with using Bluetooth . 3 days with. Bluetooth .

These batteries have a long life being used every day. The only downside is how small they are, but if you use a battery storage case - you won't use them. It definitely met, and exceeded, my expectations. I truly can't think of a room to improve, as the size is very important. Perhaps a different coating beside silver?

Bought a multi pack of 3 cases of 8 batteries and over of them are dead. The date on packs say good until Mar 2022.

I think these batteries last the longest, but the packaging is unnecessary and all goes straight into a landfill. None of it can be recycled nor can the cases be used for any other purpose. If a battery has less wasteful packaging but doesn't last as long, I would still be tempted to choose the less wasteful product. Duracell -- you can do better!

Just wanted to express my displeasure with the Duracell 312 batteries. They continually give off a low battery sound and the life of the battery is 2-3 days compared to 5-7 days I get with non brand name products. I have had a continual problem since I got my new hearing aids last June. Had a similar problem when using with my prior hearing aids. My audiologists said she had heard similar complaints from other patients and suggests that her patients get drug store brand batteries since her patients say they have better success with them.

Didn't even know Duracell made hearing aid batteries until I saw them in a store, so I bought a pack to give them a try and so far, I find they last longer than the other brand I was using...

Poor quality hearing aid battery. Short life. Only 4 days. Other brands generally last about 6 days. Guess I'll switch back.

I have had a hearing aid using this size battery for quite a few years now and fairly recently bought Duracell batteries and am in awe of how long they last - I would barely get 2-3 days from another brand but the Duracell are lasting around 8 to 9 days and that is with all day use from the time I get up until I go to bed at night.

I have purchased two of the 24 packs and at least 6 of batteries in both packs were dead.

At any given time the batteries will stop working & then later start again. I threw out several because I thought they were dead even though they had only been in use a couple of days. There is definitely something wrong with them. I'm switching brands.
