Size 312 Hearing Aid Batteries (60 batteries)

Good value and last a reasonable time. Don't know how they compare to top line expensive batteries but these do a good job for me.

UPDATE: with advice, I've decided to change my review. These are excellent batteries and an excellent value. With removing the tab, then putting the battery in after several minutes, they last a long time in my hearing aides. More than a week. I use them more than 12 hours a day most days. They might last longer. It feels like I hardly change the batteries. I'm so happy I found these. I've ordered more. Unbeatable! Thank you!previous review below:For quantity wise, it is worth the money. Quality wise, its still worth the money, but did encounter small problems. When putting the battery in, sometimes the hearing aide wouldn't turn on, or my hearing aide would beep indicating low battery. I brought my hearing aides in, to ensure are working properly. They are working fine. I just have to turn them off and on a few times and the battery starts working. They last about a week for me. I use them about 12 hours a day, almost daily. All in all, I would say 60 batteries for around $12.00 was worth it, and I am satisfied with my purchase.

These batteries come in a pack of 10 cards holding 6 batteries each 1.4v. The six batteries per card allow easy dispensing by rotating and dispensing each battery. It is very nicely packaged and appears like a premium product but looks are deceiving. The batteries which were purchased in March 2013 with an expiration date of 2016. Initially the batteries worked quite well and lasted 7-10 days in my hearing aid. However, one year later, it's 2014 and most of the new batteries from 2 different cards were DOA and didn't last even 1 minute. I took out twelve batteries and only one worked. I thought first it might be the hearing aid but switching batteries and hearing aid produced the same result.Batteries that have a shelf life of 3 years should still work when taken out of the package unopened one year later. I initially rated them 4 stars, but with a very short shelf life, they deserve a rating of 1 star. These batteries are unacceptable and should be avoided. Most air cell batteries have a very short life once the brown seal is removed and 7-10 days can be expected. The shelf life is very important. If you still chose to buy them, expect a shelf life of less than a year. I am going to stick with a brand name that I know will work up to the expiration date. (Please note this review was updated from April 2013.)

My 90-year-old Mamaw has been using hearing aids for as long as I can remember, and it bothered me how much she was having to spend on hearing batteries. For the past many years she's been spending roughly $16.00 for a 36-count package; one pair of batteries lasted her 3-4 days, typically.I decided to look online for a cheaper option- if hearing aid batteries are going to be relatively crummy, she might as well by the cheap ones, right? I found these, 60ct for $15.00, and convinced her to give them a try. They came in a couple of days later and she's been ranting and raving about them ever since.Where her previous batteries lasted 3-4 days, these have lasted her 7, every time. Where one battery went out sometimes 12-24 hours before the other (when they were put in at the same time) with her previous batteries, these go out within hours of each other. On top of that, she claims that these batteries make everything she hears sound CLEARER. (She says "I can't /hear/ better, I can just /understand/ better") -- Even if you're doubting the ability of these batteries, just do the math to see if they're worth trying:Changing batteries every 4 days (and this is the high end of the lifespan, remember?) leaves you using 182.5 batteries per year. 36ct packages costing $16 each was costing her roughly $81/year, just for batteries.Changing the batteries every 7 days leaves you using 104.3 batteries per year. 60ct packages costing $15 each (their price when I purchased them) now only costs her roughly $26/year.

Maybe I got lucky?? After researching a lot of brand reviews for hearing aid batteries, I cautiously chose this one since the batteries average out to only 19.6 cents apiece and I love bargains. I say cautiously because there were a few very negative reviews on Amazon for this product, but since the price of $11.70 is only about the price of a cup of coffee at McDonalds these days, I didn't have much to lose.I have dual Phonak Audeo Smart digital aids which I put in when I get up in the morning and do not take out until I go to bed (other than taking a shower). I've heard digital aids are more power hungry than other types, but since these are my first pair of aids, I really don't know if that's true or not. The battery expiration date lists 2016, and I mark on the calendar the day on which I insert a new pair (I always replace both at the same time even if the audible battery warning only goes off in one ear) as well as the time of day. To be fair to the negative reviewers, I have only used 6 batteries so far (out of 60), but each pair has given me exactly 7 days of use, so I am thrilled. I've had my aids about 6 months now and when I purchased them, the audiologist included 2 packs of "Power-One" batteries. They lasted an average of 5 days and here on Amazon they are roughly 40% more expensive than these. As I said in the beginning, maybe I just got lucky, but so far, I could not be more pleased. If I get some out of this batch that are bad or are short-lived, I'll revise my review at that time, but for now I'll go with these.UPDATE: 11/09/2013I've been using these batteries for 10 months now, and always reorder as needed. In 10 months, I have had only one battery that was D.O.A. I keep a record each time I change them, and every pair gives me 6 days of use...no more, no less. For the price vs buying them locally, they can't be beat. Very satisfied.
