Packaging My hearing aid batteries go dead at the most inopportune times. I carry a pack in my handbag. Because of the packaging, the batteries stay put and don't fall out to the bottom where they are difficult to retrieve. May 2, 2012
I haven't gotten the hang of using this packaging yet Earlier this year, I took my mother in law to a medical appointment. Returning home, the sun was right ih her eyes, so we stopped at a CVS to get her some sunglasses. On the clearance rack was three of this item. At that time, my father in law was still alive & he liked this packaging. Daddy died a while back, so I got all the batteries. Lucky for us, all three of our hearing aids take 312 batteries. I haven't gotten accustomed to changing my hearing aid batteries in this packaging yet. My preference is the tear-away single "bubble" packaging. But these batteries all work, as long as I get the correct number. Our audiologist actually recommended a different brand, but said "any 312 battery will work in your aids. The only difference is how long they last before you have to change them." He was right. I generally get a little less than a week on a battery, give or take a day or two. But, at the riduculous low price I paid for the batteris in this purchase, I wouldn't care if I had to change them every day. May 2, 2012
They last a long time. Because I wear two hearing aids, I buy the 16 pack of batteries. Each battery lasts me for three weeks which is not only a convenience but a savings as well. The package design makes them easy to carry in my purse because of its size and secure positioning of the battteries. The tabs makes installing a new battery very easy. May 1, 2012
The size , the packing is just perfect yo carry with .th I recently purchased this pack . Before - I was in habit of carrying only one or two batteries with me- and - without exception , I never could find it .What pocket ?? And , very often , if I was near a drug store , I would just go in and purchase new pack . They do not sell singles . Now- I put a pack in my shirt pocket - and - no problemo. And - almost forgot - it seems that they last for ever. December 30, 2011
Lasts the longest over others tried. Getting samples from many other manufacturers, I could compare and so far these are the best, longest lasting. December 22, 2011
Great product I love your hearing aid batteries. They outlast any other brand of battery I have tried. I've worn a hearing aid fr 25 years now. and I've tried lots of brands, name brands and generic types. Energizer just last and perform better. December 18, 2011
energizer hearing aid batteries E nergZier hearing aid batteries are the only ones i will use. I find them easy to use and long lasting I wait until they go on sale and usually have a coupon. a very good value December 18, 2011
312 HEARING AID BATTERIES I like these batteries because they are easy to handle for my mother of 94. The tabs are long enough for her to put the battery in the hearing aid. The only thing I'm not happy is that all batteries last between 4 - 6 days on her new hearing aid - where the old hearing aid batteries lasted almost 2 weeks. December 18, 2011
