POWEROWL Hearing Aid Batteries Size 312, High Capacity Cell, Long Lasting 312A Battery, 24 Count

These work as well as the higher priced name brand batteries that have been around for years. And you get a good quantity battery for the price. They last the same amount of time that the higher priced name brand batteries last. And actually I am hearing better so I think they are working better than name brands I have bought in the past because my hearing needs have not changed. I am very happy with my purchase.

Reading reviews about the difficulty of getting to the batteries led me to conclude the purchasers must all be physically disabled. I would like to take this opportunity to apologize to all I had maligned. I first got the cardboard part separated from the plastic discs holding the batteries. I realized there were 2 sections: the part holding the batteries and another disc retaining the batteries. This looked deceptively simple. Just separate the discs and the batteries will fall out. Well, the Chinese must have developed a super-duper glue because those discs were never going to separate. So, following the advice of others, I attacked the plastic with first, scissors, then wire cutters without success. Again, the Chinese must have developed a clear plastic as a substitute for Kevlar. Finally, after watching the video of a guy who successfully got his batteries out, I used a heavy duty utility knife with a good, sharp point to penetrate the plastic in the right location as shown in the video. Then, punching through the plastic at the next battery location and joining the 2 existing holes by several puches between them, I was finally able to do enough damage to the plastic to slightly bend up the part between the batteries. Continuing this around the part holding the batteries and bending up section by section, my batteries were free! Fortunately, I still had the container with 2 batteries left from another manufacturer so I filled the empty spots with these liberated batteries. So easy to get at these. Now, to see if the lifetime of these is sufficiently long for me to recover before I tackle the next "easy-open" package.

The batteries are great - easy to use and last a good week! This is the second time I've bought them and will purchase again!

The batteries themselves is a 5. However, I rated it a bit lower due to the packaging. They're difficult to get out. I had to cut them out with a box cutter because scissors wouldn't work. Need to make the package easier to open.

Great product, great price, immediate shipping.

Do not waste you money on these Chinese rip off's.. they say child proof, well they are also adult proof, it takes a pair of pliers to open the package.. My normal batteries would last from 6 to 8 days, the best I have gotten from these is 5 days and several just 4 days.. They are just not worth the money nor the headache trying to open the package... They don't deserve even one star but I had to use a least one...

The batteries work properly in my hearing aids, but removing them from the holder is a real pain. These are marked as being child-proof but also seem to be largely adult-proof as well.Instead of opening a slot on the back of the holder and allowing the battery to drop out I found that I had to separate the top and bottom plastic sections of the wheel holding the batteries and then pry up the top portion. I did it using my fingers and nails but it is probably better if you use a needle nose pliar. Getting the batteries should not be so difficult.

Rather a maintenance item,, but these hearing aid batteries last a long time compared to other ones that I have tried. I don’t have to change batteries so often, and they continue to work long enough after the dead battery sound that I can easily wait until I replace them.
