Rayovac Hearing Aid Battery, Size 312 (60 Batteries)

Please don't waste your money on Duracell or other brands of hearing aid batteries. The RayOVac batteries last longer than the others by far. Not only that, they are consistent in how long they last. The other will quit sometimes after only 2 or 3 days I have Siemens and Opticon hearing aids and they work great in both brands.

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.

Lasted as long as any other

My blind elderly hard of hearing mother spent 32 minutes this morning trying to get the battery out of the new packaging. Bring back the old tab pull down packaging in order to make the batteries accessible.

The batteries are the best but the new packaging is the worst. It is almost impossible to get the package open. The company should have considered the fact that most of their customers are old and frail.

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.

Very good product and easy to use

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.
