DURACELLActivair Hearing Aid Batteries Size 312 (80 Batteries), Brown

Unlike some other reviews that I have seen regarding this product, I wholeheartedly approve of this product.It is everything I expected and more. I have been looking for a suitable replacement to the overpriced inferior batteries provided by my hearing aid provider. These batteries are rated higher overall and cost almost half as much as the ones I was using (OnePower).A big part of my approval upon receiving these was my relief that unlike other reviewers who just said they were packaged in the difficult to open packaging, these are anything but that. (see the photos of the product I received today). I have had to struggle with trying to pry open, both tearing and cutting the packaging to get at the batteries sealed in a circular ring. These have the extended tabs, come 8 in a resealable plastic container, 10 containers to a box. These have got to be the most convenient replacement batteries to use. Someone put in a lot of effort being sure they are easy to use. Finally, from everything I've read, these Zinc-Air batteries have more power and are longer lasting than any equivalent alkaline hearing aid battery.

One of the best companies I have ever dealt with. The device is extremely well made, easy to use, and can be used with almost any existing dog collar. I am a scientist and understand the requirements for devices like this very well. I’ve been using the whistle 3 for two months now and it has worked perfectly. You are notified within a few minutes when your dog leaves home (you are texted and or e-mailed a notification with her exact location/street address whether (yes its a she for me) you are with her or not. When we go for a walk it is never more than 10 or 15 feet off the exact address. You can open the app on your phone and see exactly where she is and where you are on a street map. Just like you can follow your travel in a car on your handy dandy gps. Today she is in St. Louis Mo, and I’m in Flagstaff Az. i can see what home she’s in and what she is doing any time I like.If she runs off I can track her minute to minute whether she is at home, at the dog park, or 2000 miles away...and I’ve done all of those things. Of course real time tracking will use up the battery faster so you may have to recharge it more than once a week. Well the damn thing is smart enough to send you a notification that it needs to be recharged soon too.It also sends you tons of info every day and weekly summaries too of activity (yours and your pets)Oh and the customer service is great too. They are responsive, communicate in people talk... not technical mumbo jumbo, and help you quickly resolve your problem or questions. I’ve had a few questions and they are spot on every time. Can’t think of but one or two companies in my lifetime who have been so pleasant and easy to deal with. Did I forget to say it is far less expensive than most of the competitive trackers and services? Nope, I just said it.I’d have to say the device and the company have far exceeded my hopes and expectations to this point. Worth every penny and more. Now if I could just figure out how to attach one these things to my kids I’d sign up for two more in a flash. If you love your pet you will love this tracker. 😀😃😀

Comparable price. Good, working batteries. Has become go to when need hearing aids batteries.

Good Product but the charge does not hold like Energizer Batteries

Works for my needs!Quanity was a major role player for me. Seems my hearing aids drain batteries like no tommorow, so that was a decision element on my part.

Must have for Hearing aids, 80 for a great price.

A complete and total misrepresentation on the packaging. Duracell has a great reputation for quality batteries made in Germany. The posting shows the nice plastic easy access cases with 8 batteries which I appreciate because I have fine dexterity issues with my hands and they are easier than the traditional cardboard dispensers with the rotating plastic case. So I ordered these and when they arrive not only are they not in the nice plastic cases shown in the posting, but they aren’t even the traditional dispensers. They are literally in a sealed carrier that requires you to use scissors to cut the package in order to access a battery. My guess is that this is an intentional design to prevent air from getting to the batteries and prolongs their shelf life, but it isn’t what is being advertised and they are a horrific inconvenience and useless to carry in your pocket unless you want to carry scissors also. Ridiculous and misleading.

The hearing aid batteries were as represented, and delivered in less than a week. They have an expiration date almost 5 years from now.
