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.

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.

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 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 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'm not sure why people say the battery life is short. I use my hearing aids for phone calls, listening to audio books and podcasts, and listening to movies pairing with my remote microphone. The batteries last a week or longer. Maybe they're not storing them properly or not allowing enough time to activate. These work better than Energizer or other top brands. They're priced right and the cardboard packing is easy to access. They're perfect for me.

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’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.

These batteries are just as good as the expensive ones . Use all the time

not sure yet this is a good thing. they don't offer the name brand so trying store brand.
