These batteries last about 3 days in my hearing aids, the name brand lasts 7 to 8 days. These are half the price of the name brand so the cost verses the more expensive are about the same. The name brand batteries are more consistent to me.

I bought a package, but won't do it again. Well over half the batteries in the card lasted less than a day - some only a couple of hours. None lasted even three days. I won't make that mistake again.

Pass these up and buy the name brand batteries! These don't even last 5 days in my hearing aids. More like 4 1/2 days. Wish I had spent the extra $5 and bought the name brand.

I tried these batteries since Sam's no longer carries Duracell. The worst thing is the tiny tabs, which are hard to handle. Initially the battery life was good, but lately they seem to quit sooner. Wish Sam's would bring back Duracell.

To those having trouble with opening... use one pliers with needle nose pliers to easily pry open the goods. Batteries are often duds and fail to work after a month of storage.

Cheaper than batteries that I get from audiologist by about 1/3 but only last 4 days instead of 6-7 days . Long term, the price per hours used is the same.

Do Not Buy this! I did on 10/3/22. Thought my HA were broken because I kept hearing random dings and they would randomly turn off and on. When in desperation, I used my husband's nearly new HA and... same problem. SO, this week I put ENERGIZER batteries in. Not one single random ding and these batteries are going strong 6 days later. Members Mark batteries are NO GOOD! I have 18 left of this whole pkg. of 40. Guess I'm a slow learner.

I have used several packages of these from Sam's. I may have a couple that did not last a full week, but not enough to not buy them at a very good price. I have used the 312 for about 5 years and used Audibell batteries, for which they also had some that didn't last or work at all, Duracell, and Everready batteries. Since I cannot get my batteries free( due to the

I normally buy Energizer or Duracell but thought I could try out these instead as the price is half that of those brand. Batteries lasts long enough for my hearing aids but the only problem is the tiny plastic tab which is used to remove the battery and position it in the battery compartment. It's too small for adult fingers. Hence 4 stars

I’ve always purchased Eveready or Duracell and they would last 5 days 16 hours a day use. I tried Members Mark and am lucky to get 4 days of use. I’ll never buy them again. I’ve had my hearing aids for 4 years and they Bluetooth to my iPhone. They’re not worth the lesser price.
