    • Rechargeable hearing aid batteries
Finally! Rechargeable hearing aid batteries that actually work and last at least 12 hours per day. However a little pricey at $70 per piece. But supposed to last a year. Hope so.

    • Pila recargable para audífono, compatible con las de Zn-aire.
Empleada en audífonos Oticon, se recargan cada noche con un cargador específico de Z power. La vida de la pila es de unos 500 ciclos de recarga, tras lo cual pierden capacidad y ya no aguantan todo el dia. Oticon facilita una tapa del audífono que permite recargar la pila sin abrirla, simplemente depositando los audífonos sobre unas cavidadades del cargador, quedando fijados magneticamente. Opción ecologica para quien quiera minimizar los residuos. ... show more

    • This battery only lasted 3 months.
I had ordered this battery in 2022 and had no problems at all with it. However, this particular battery, which was ordered in February 2023, has already fizzled out. It won't charge anymore. I showed it to my audiologist and she agreed that the battery had already died out. I hope to get another battery to replace it and I hope the charge is much less due to this present battery being only 3 months old. ... show more

    • These work with Bernafon hearing aids and ZPower battery charger
The hearing aide provider told us they could no longer obtain ZPower batteries. We were most please to find these ZPower batteries on Amazon. While fairly expensive they were cheaper than buying new hearing aides. And they worked as promised

    • How long will these hearing aids work
The Z power rechargeable hearing aids are working very well. They are brand new. I will be interested to see how long the maintain their ability to recharge fully and provide full charge. My original Z power batteries I got with my hearing aids (got them before the company went bankrupt) lasted for 1.5 years, probably longer than expected. I hope these last that long too. We will see. ... show more

    • Batteries don’t last very long.
The battery life doesn’t last very long. I can get a good 8-10 hours out of them for normal use. Using them for anything else, lowers the life significantly. I love the fact that they are rechargeable. Just wish they would last for more than a day on one charge.
