Power One MERCURY-FREE batteries are manufactured in a specialized hearing aid battery plant in Ellwangen, Germany.We provide eco-friendly battery technology, produced under clean room conditions, with an Enhanced Safety & Performance housing coating.Power One batteries are manufactured using only high-grade and refined raw materials. Our energy management system is certified in accordance with ISO 50001. With the new international standard, energy consumption and energy policy are placed center stage.Hearing aid energy with premium performance and durability - with the patented stable high level of voltage that Power One provides.-----Why zinc air technology?Zinc air batteries have an especially high energy density and exhibit an almost flat drain curve. They are therefore the ideal power supply, especially for today's digital hearing aids.The air holes of the battery are initially sealed with a protective tab. They are kept in this way, in an "inactive state", until they are needed. The inherent self-drain of zinc air batteries with protective tab attached amounts to a mere 3% a year. The film is removed when the battery is inserted into the hearing aid. After several seconds of activation time, the battery begins to produce current.In the activated state (with protective tab removed), zinc air batteries can only be stored for a limited period and should be used as quickly as possible.After removing the tab, please wait for 5 minutes so that the battery can fully activate and function at peak performance.

Work well

I don't know where to start other than my audiologist charges THREE TIMES the cost for the exact same brand and pack of 60 batteries that I get at Walmart. As far as I'm concerned Power One batteries are the best. I've been using them in my Oticon hearing aids for years without a single defect.

Don't pay more elsewhere, shop Walmart and save.

Top of the line batteries. I use them for my hearing aids. They last me for several days. They are from the same company, Power One, that I get from the Veterans Administration.

Good product. Highly recommended.

the best hearing aid batteries I have used.

better hearing

They last longer than other batteries I used.

Good battery

good value  only half of them had a charge  only lasted a few hours in my hearing aids

hearing aid batteries

I bought these as an option to the retailer I normally use. COVID  has changed supply chains and I didn't want to wait in line only to find out that they are out. Convenient to purchase online. Shipping costs seem high given the size and weight of the product.

Looks like the right size

Way too many of the batteries in the box were either unusable immediately, or became unusable within a few hours.  Some were all right, so 20-30 hours use in hearing aids.  Roughly 20-25% didn't offer my money's worth of use.

Uneven quality

did not like them. The batteries lasted about 4 days. Very disappointed. Would not buy again
