Rayovac Extra Advanced, Size 13 Mercury Free Hearing Aid Batteries (Pack 80 Batteries)

Each batter lasts about a week, which is as long or longer as the Duracell and Energizer brands. Great bargain.

I love this brand. They work well and are a reasonable price.

These batteries last a reasonably good amount of time for me. AND they have the easy open packaging...a must for me.

Exactly as described and worked great

Wearing a hearing aid for 56 years I will never go Wireless batteries are the best but the problems buying batteries in the stores today they have it way over kill on child safety you can't even open the darn battery pack seriously if you have hand issues or you're older you have to have somebody else open the darn package these are the old style and I pray to God they continue to be the old style and just remember you guys hear it batteries should always be left in the freezer yes or the refrigerator to last longer a lot of people don't know that but your batteries you're here it ain't batteries will last longer if the refrigerated or freezed like I said 56 years of wearing hearing aids and and more every single hear a date from around the ear to in the ear God please do not let the ENT or the hearing specialist make you go battery less what do you what are you going to do when you go camping or you have to have all these Chargers and it takes too damn long to charge it in the warranty sucks batteries are the best

I don't like the "new" child proof packing. I know about the issue with children swallowing these batteries but I'm 69 years old with arthritis and it's really hard to open. I think the best solution for the children is for parents to lock up or put up high.

I've tried other brands and keep coming back to these. They last about a week in my hearing aids.

I switched to these batteries for my hearing aides and they last at least 2 days longer than any of the others. In addition, some other brands I was getting dead batteries from the start. That hasn't happened with these so far.
