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

Good value for the price and long-lasting

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.

Some of these of batteries only lasted a day. Some didn’t last two hours. And two of the packets had batteries that didn’t have any charge. I have ordered batteries from this seller many times in the past year or so and never had any problems. But this was terrible. I was constantly removing and installing batteries in my hearing aids which is already tedious but to have to do it over and over in a short span was bad. I need my hearing aids to work and last at least three days. AND the worst is the new “human” proof packaging. As anyone who uses hearing aid batteries knows you have to use scissors to cut open the packets. The batteries are small and can fly out and get lost. You cannot do it easily in a car e en if parked AND you have a pair scissors handy. So imagine going through that process ten or twelve times in the span of ten minutes and still have no results.

These batteries are good quality, but the child-safe packaging makes it VERY hard to extract them. You need sharp scissors and persistence to get them out.

Terrible, cannot open packaging

Good price

Good batteries.

EL VENDEDOR ES MUY RESPONSABLE Y LAS BATERÍAS SON DE MUY BUENA MARCA, MUY BUENA CALIDAD Y MUY BUEN FABRICANTE, ES UNA MUY BUENA MARCA DE ALTA CLIDAD, EN MI CASO LO RECOMIENDO PARA USUARIOS DE PROTESIS AUDITIVAS COMO PHONAK, YA QUE A MI PACIENTE LE FUNCIONAN PERFECTAMENTE.

Cumplen con lo esperado

Hola, He comprado varias veces ésta marca pero este paquete de pilas no duran nada ... Con otros paquetes tenía una duración de 4 a 5 dias y con éste paquete estoy cambiando cada 2-3 días. Mala calidad... Voy a tener que cambiar de marca ...LO raro es de que con los paquetes indicviduales de 6 la durabilidad era mayor y ahora con los paquetes de 8 pilas la durabilidad bajo a la mitad !
