## Description

Power One Size 312 Professional Hearing Aid Batteries. Package of 80 batteries. New stock.

Review: Happy overall. - 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
Review: Reliable quality and long life - Good value for the price and long-lasting

Good value for the price and long-lasting

### ⭐⭐⭐⭐⭐ Good packaging; long lasting
*by M***G on January 14, 2026*

I used to buy my hearing aid batteries at Costco (Kirkland brand), because their prices were so good. However, the last batch of these batteries from Costco were in different packaging that made it very hard to get into without scissors. They made them childproof, and in doing so, made them virtually impossible for older people to get into them. That is why I switched to these RayoVac batteries that are in easy to use packaging (not childproof). These RayoVac batteries last longer than the Costco batteries too, so when you take that into consideration then the price is reasonable. If you have children in your home, then you may want to get the Costco batteries and fight with the packaging every other day to get a set of batteries out. Or, buy the RayoVac batteries and hide them from the kids.
