Rayovac Hearing Aid Battery, Size 312 (60 Batteries)

I have worn hearing aids for 40+ years. Batteries have come a long way since the huge ones once needed. I order these rayovac about every 9 months. More than enough batteries and the price cant be beat. Most drug store batteries are about the same price but you only get 8 batteries. Here I get 60 for the same price. Failure rates are rare and about the same as the drug store bands. Well worth the cost. SInce you can get a lot you can keep them everywhere.

These batteries are great! Each set will normally last 7-8 days, which is better than the more expensive ones.

In 2024, I wrote the following: "I have chosen and used this brand of battery for years. It is reliable and the price is good. For me I get 4-5 days continuous use. "Today, 28 Mar 2025, I started using this box, and the hearing aids are telling me on the day I install them, that the battery is weak. So I measure the voltage. It's 1.37v. I try a different voltmeter. Same reading 1.37. I try a different cell. It reads 1.38v. It is supposed to be 1.45v. The package says, "Use by 2028-02-26".So, I will no longer purchase this product.

better value than a box store

Very good product and easy to use

These are the longest lasting hearing aid batteries I have used. But the new packaging is terrible, you need really strong hands or really sharp scissors to get a battery out and you have to cut out battery everytime you need one.

Bought 2 boxes (12 packages per box?) All worked as expected through the first box and midway through the second box. I know it sounds like they just expired, but they were marked until 08/2025. I'd keep popping them in, (after the appropriate amount of airing, of course,) and they would either last a few minutes or be completely dead.Unfortunately, I have seen this on reviews from other sellers as well, and assume you're just going to run into it now and then.

Batteries seem good but they need to be more customer friendly. You have to cut them out to use them. I will use them because I bought them. I will cut them out and put them in a bag for easy use. I won’t buy them again.
