Power One Size 312 Hearing Aid Batteries (80 Batteries)

Works just as well as costco, is half the price - 2x as many in package. Lasts about the same amount of time 3 days, which I've heard from friends is comparable. I do try to take them out at night which makes some extend about a day longer. I like the sticky piece on the back of the battery which gives you something to hold on to while trying to put it in the slippery hearing aid Itself. The only downside is the batteries are REALLY hard to get out of the package. The wheel turning area that holds in the battery sometimes will not turn at all and you actually have to rip apart the container holding the batteries. That is aggravating since the Walmart and the Costco wheels turn around easily. But for the price difference I will keep using these

They last about a week in my hearing aids.So I know about when I will need to replace them.Thanks

These are for hearing aids and ordering them in groups means that they are always on hand when needed. Only down side to these batteries is they cannot be discarded in the regular trash but must be held until an e-waste trash drop off is scheduled.

The batteries continue to be high quality and last longer than many other brands. HOWEVER, this new “childproof packaging” that requires a scissors to access a SINGLE BATTERY is ridiculous. Just make the carton childproof or something. Not only that but zinc air batteries are actually quite safe, they would just pass through your body if swallowed. The Reese law case occurred with lithium ion battery from a remote control.It’s crazy they expect people to carry a scissors around to get a battery. What about people that fly? What about those with Parkinson’s or tremors? This had to be one of the most unnecessary and time wasting changes I’ve ever seen in a product, and I say unnecessary because I believe there’s an exemption to the law for medical uses.

work great

They are really a very good product and last for a very good price ,THANK VERY MUCH.

I have used the Power One brand before with no issues. This is the first time I purchased them online and I have had nothing but problems. When replacing a battery in my hearing aid sometimes they do not work, sometimes the work but it is delayed and sometimes I get indications of low battery life, but they still work for days. It seems that the adhesive that is to protect the battery life before use is defective, or the batteries themselves are near the end of life. Regardless I have 27 batteries that I will not use.

Exactly what is needed. Thanks.
