VARTA Power One Zinc Air Hearing Aid Batteries (Blue) Size 675 Pack of 60

As a user of hearing aids for about 5 years I have used two different types of hearing aids, both analog and digital. The first set of aids were analog and they used a button battery type 13. My current digital aids now have Bluetooth and use these P625 batteries. Incredible improvement in the length of useful time these P625/R44 are able to provide. My experience with these German made “Power One” has been great. There has been no leaking or inoperable batteries and as previously mentioned the energy provided is significantly longer lasting. Uncertain as to comparable energy consumption of the analog to digital hearing aid devices. Great product at a great price. Highly recommended.

Good Batteries for my grandpa's sound amplifiers

I get about a week and a half on one battery in my high powered hearing aid.

This is the second time I have purchased these batteries. I had never heard of this brand before getting a pack from my audiologist. Since they seemed to work well and the price was so good, I ordered a box of 60. They power my hearing aid for a good length of time and have a long shelf life. My first box lasted well over a year and I did not notice any power loss as the batteries aged. Once the batteries are opened, and the charge depleted, (after use) it does seem that they start to corrode rather quickly, so I do try to get them out of my purse and into the container I collect them in for disposal within a week or two of using.

I received my Cochlear Batteries fast, at a great price. I am so glad to be an Amazon Prime Customer and so glad that vendor is a part of Amaon Prime. This is why I have Amazon Prime. Thank you.

I had upgraded my hearing aids, in which the last set was using size 13 batteries, and they lasted about a week. I have since upgraded to a later set of Phonak H/A's (Naida P70-UP), and these batteries are lasting up to 3 weeks. I stream a lot via my H/A's, which uses one of the 2 aids for the streaming, and that cuts that aid down to 2 weeks.Not sure what other 675 batteries do, but I've read up on these a little, happy with them, and will most likely stick with them.

They’re a good hearing aid battery, lasts a decent amount of time.

I've been using these for years and find they're the best and most economical batteries by far. I use them for my hearing aid and one package of 6 batteries lasts me 4 months. Broken down, that's about one battery lasting for 2 weeks. Not bad at all. This is the first time I purchased a 10 pack. (You get 10 packs of the 6 count packages in a box with this order.)The expiration date that arrived today (8/17/16) says 1/2019 on all 10 of the packages. That's pretty good and doing the math, it works out to these batteries needing to last me until December of 2019, so if they still work until then, i'll be happy, but even if they don't, at this price ($14.75/Prime), i'm still saving money buying the bulk and lasting to the exp. date of Jan. 2019. Nice to know I probably won't have to buy these until the next decade!Best bang for your buck, great product, and highly recommended!
