Rayovac 312 Extra Advanced Mercury Free Hearing Aid Batteries 80 Pack

I have been using these batteries for over a year. I usually get 4 to 5 days about 17 hours a day of wearing my hearing aids. But this last box some of the batteries are not lasting 24 hours. In fact I put new batteries in last Saturday and 2 hours later one of the batteries was dead. I have lost a whole card od batteries in this last purchase. NOT THE SELLERS FAULT. It is Rayovac, tried to contact them 2 weeks ago, filled out the contact info hit submit and was told to try again later. Unable to submit.

So we just reordered these after nearly a year ago for use in one hearing aid. Great price and awesome longevity.

Notified batteries had arrived, I looked and they had NOT. No pic taken of delivered item, and next day a ripped bag was there instead. Have read this is happening to others. These batteries I've ordered before last a reliably long time. Amazon commendably giving credit for these missing ones. What's going on, how often and why needs to be resolved ASAP, however.

I’m having a problem trying to find something to say about hearing aids…they work and are a decent price…

I’ve been using these batteries for a year or so with no complaints. But this latest box has been quite unsatisfactory - several batteries have been dead when I installed them. When I peel the backing off before use it seems that some are not stuck on as well as they normally are. For my next order I will be trying another brand.

Once installed they last A good while but if it’s for a single hearing aid then by the last pack or two they start loosing power

Batteries last six days 👍🏻

These came fast and they hold a charge for longer than a day. I do air in refrigerator.

Gran producto de la mejor calidad y duración
