Duracell Hearing Aid Size 312, 12 Count

Poor quality hearing aid battery. Short life. Only 4 days. Other brands generally last about 6 days. Guess I'll switch back.

Not only do the Duracell hearing aid batteries last the longest, we find the packaging most helpful as my husband has neuropathy in his fingers. The hard case and long peel off tabs make it so easy for him to change the batteries. Thanks Duracell. Mr. and Mrs. Jim McNichols, Orlando,FL

Hearing Aid Batteries are air activated. When you pull the tab off you must let it sit in the open air for about 45 seconds to let air get in the very small holes to make them active. They can be in the Aid just don't close it up for the time required. If you close them up in the Aid their life span will be very short.

[This review was collected as part of a promotion.] I received the Duracell hearing aid batteries in my Bzzcampaign box. I was happy to try them out since batteries can get costly. I was pleasantly surprised by the ease of changing out the batteries in my hearing aids. I loved the idea that they were long lasting and not toxic. Containing no mercury was not a previous concern because I needed the batteries regardless, but presented with an option that is mercury free is a bonus. The length of use has been holding up since switch to the Duracell batteries. I give these a thumbs up! Thank you for letting me try them!

[This review was collected as part of a promotion.] So my review is they last as long as other hearing aid batteries. Would I buy them yes in a pinch. They last about 16 hrs which is as long as the opposing brand.
